Need faster approach to load data in NSTableView from a file

Abhijeet Singh — 2012-10-26T11:17:17

Hi,In my application I am reading data from a text file and displaying it in NSTableView. There are 6 columns in my tableview. My problem is when the records in file are more it takes too long to read and display the data. e.g. It takes around 1 min to read and display 70,000 records from the file. I am using NSArrayController to update my NSTableView. Please suggest some solution to make my application faster. Should I read and display only that much data that is visible to the user (like in iphone but i dont know how is it done OSX?) and update my view on scrolling?Thanks & Regards AbhijeetGet Yourself a cool, short < at >in.com Email ID now!

Dragging file promises

Christiaan Hofman — 2012-10-06T11:24:30

I am trying to figure out how to drag file promises from views such as NSTableView. Before 10.6, I knew how to do this using NSFilesPromisePboardType and the namesOfPromisedFilesDroppedAtDestination: delegate methods. The docs now say I should use (NSString *)kPasteboardTypeFileURLPromise instead of NSFilesPromisePboardType. However, I cannot find anything in the docs, no sample code or whatever, that uses this. The only thing in the docs still refers to NSFilesPromisePboardType, or uses dragPromisedFilesOfType:..., which is not appropriate for standard controls such as NSTableView (because that should use this implicitly behind the scenes). Just replacing NSFilesPromisePboardType by kPasteboardTypeFileURLPromise also does not work, the delegate method is never called. So can anyone tell me how I do file promises in 10.6+ using kPasteboardTypeFileURLPromise?

thanks
Christiaan

iOS Developer Enterprise Program

Jack Harris — 2012-08-19T11:46:01

I am looking into the details of this program and was wondering if anyone
has any experience with it here.

What I am interested in learning about, for the moment, is the distribution
of in-house apps. Specifically, what procedures do you follow to vet the
apps that go into your in-house app store? Are there any good, public,
resources out there that discuss this topic as to what tests / procedures
to follow to make sure an app being placed in the App Store, for example,
doesn't use any private APIs, does not send data when it also claims it
won't, etc...?

Thank you.

NSImageView display problem

Abhijeet Singh — 2012-06-13T06:59:33

Hi,In my application I am displaying an image received from some third party camera library function in NSImageView on screen. On "Capture" button click the image is first saved on hard disk and then I display that image on screen. It works fine during the first time when I start my application. But when I close the window (not the application) that has NSImageView and comes back later the NSImageView stops updating. On Capture button click the new image is created on hard disk but NSImageView keeps showing the previous run's image. I am using a modal window here. I even tried to clear the NSImageView on window close button click (using [imageView setImage:nil] ) but still screen shows the old image when i open the window next time.This is what I am doing on Capture button click Create CameraImage.tiff file using third party camera library. (The image is always saved with same name hence overwritten.) Display image in NSImageView. Here is the code for displaying the image (vo
 id)displayCapturedImage:(char *)imgname contrastvalue:(double) camcontrast{NSImage *image;image = [[NSImage alloc] initWithContentsOfFile:[NSString stringWithCString:imgname encoding: NSUTF8StringEncoding]] ; [calibChipView setImage:image];[calibChipView setNeedsDisplay:YES];//show the contrast value [contrastfield setIntValue:(int) camcontrast];[contrastfield setNeedsDisplay: YES];[image release];}RegardsAbhijeetDear macosxdev !

Textfield background color and SDK

Christiaan Hofman — 2012-05-18T15:25:12

I found some very annoying and weird thing. When I compile my app using the 10.5 SDK (on Xcode 3) the textfields in web pages from WebKit (without style) have a black background color. When compiled using the 10.6 SDK, they're properly white. This seems absolutely wrong. But I don't have an idea why this is happening. Does anyone have an idea? I am very sure that this was not happening a while ago with the 10.5 SDK. I do need it though, as I want to 10.5. I figured out that the text fields have a clearColor set for their backgroundColor by WebKit. Anyone have an idea why this is happening, and whether there's a workaround?

thanks,
Christiaan

NSURL troubles: Apple docset URLs with multiple fragment identifiers

Gerd Knops — 2012-02-29T18:42:46

Hi Everyone,

I am having a hard time converting URL strings pointing into Apple's docsets into actual URLs. Here is an example, which works fine when copying and pasting into Safari:

file:///Library/Developer/Documentation/DocSets/com.apple.adc.documentation.AppleLion.CoreReference.docset/Contents/Resources/Documents/index.html#documentation/Cocoa/Reference/NSTokenFieldDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/NSTokenFieldDelegate/tokenField:shouldAddObjects:atIndex:

However a simple [NSURL URLWithString:urlString] returns nil when presented with the above URL. After adding percent escapes  (which converts the '#' fragment identifiers into '%23') the URL can be created, but it does no longer work (eg when using NSWorkspace's openURL: method).

Looking closer at the URL there is something peculiar: It has two fragment identifiers. Safari simply appears to be ignoring the 'index.html#' bit, and ends up with that Reference.html file, which it opens and then jumps to the location indicated by the second fragment.

Any way to make this into a valid URL?

Thanks

Gerd

Calculating NSOutlineView cell indentation

Christiaan Hofman — 2012-02-15T12:41:15

Does anybody know how to calculate the full indentation used by NSOutlineView in its cells at various leveles? And how to influence it?

According to the SL release notes this calculation is not simply (1 + level) * indentationPerLevel, as it was until 10.5. Rather it is some width for the disclosure triangle plus some indentation based on the level. First of all, do I understand that this is something like indentationForLevel0 + level * indentationPerLevel? Or are only the cells at level 0 indented differently from 10.5? Moreover, I have no idea how to get this indentationForLevel0 part, is there any way to figure that our using the API?

Apart from that, I would also like to customize the indentation. What I really like is NO extra indentation for higher levels, but I do want to get the disclosure triangle. However, when indentationPerLevel is 0, there is no disclosure triangle as well. So is there a way to change this? I have tried lying about levelForItem:/levelForRow: by subclassing and always returning 0, but that did not do anything.

thanks,
Christiaan

Atta Boys, 4 bags-full

John Love — 2012-01-26T17:12:13

The purpose of this document is to give thunderous applause to some very patient folk. But, before I crank up the volume, I would like to share with you a small amount of history.

I am within a week of finishing my Universal app, "Love Song to America" whose purpose is to support all our military veterans from World War II, Korea, Vietnam and up to and including Iraq and Afghanistan. Every last one of them, living and deceased, are true heroes and deserve all the applause and support we can generate.

The on-going process of submitting and re-submitting and re-re-submitting my mobile app to the App Store has been very, very painful and I wanted to share a glimpse of it.

I have found that all the rules in the App Guidelines manual are to describe all the official DO's and DO NOT's. The unspoken list of DO's and DON'Ts are what I am concerned about. As a strictly hypothetical example, it is entirely possible that a unspoken rule is to never, ever have need to use the More Nav Controller in a UITabController app. It is clear that no written rule stipulates that, but politically its use may be politically Incorrect.

When I submitted the app the first couple of times (without a TabBar Item pertaining to Military Support Agencies), their response essentially stated my app was nothing but a glorified web page. They were almost correct, but I countered that there are books and movie-equivalents of books. "Gone With the Wind", "Ivanhoe", "Sound of Music", and "Secretariat" come to mind. Did I forget "Cinderella" and "Snow White"? They said, in effect, "Nice Try". Their official comment was "Make Love Song more interactive". "Okay, specifically how or what do you recommend?" "Mr Love, just make it more interactive than it is". What's wrong with this picture?

I just can't deal with this, so I scoured the web and found similar experiences of many, many other developers.

I finally talked with a real human in the App Store and it was like prying wisdom teeth, but I FINALLY extracted his suggestion about the Support Agencies so veterans on the road could find out phone numbers and names to contact in case disaster struck. That idea was really, really awesome so I incorporated it … my mind was literally wrapped up in Protocols and Delegates, I didn't see the forest. But, I had to literally browbeat him to extract the idea. What's wrong with this picture?

In addition, I tried and tried to get an App Store rep to tell me how to de-pixelate all my images (one of their complaints leading to rejection). Give me the name of a specific piece of software and I'll try to use it (praying that it wasn't PhotoShop = $$$). Literally, silence. I then called directly the Apple Business section for Developers, talked to some young man who apparently took pity on me and essentially said "go to this web site and beg". The web site was Apple's Dev Support forum. I did that, and the flood gates opened and that is how I met lots of human beings with a heart. Now, that 8-minute phone call to Apple Business, what a God-send … spent hours with the App Store … but just a few minutes with Apple Business and Manna from Heaven. Do I have to ask what's wrong with this picture?

Manna in the form of:

Bill Kunz <bill-X40Io358+GFYzD5mSbZInQ< at >public.gmane.org>
pbear <pbear-lFcVscZ2ncReoWH0uzbU5w< at >public.gmane.org>
Kevin Messina <DVmagicStudios-unEuM2SsEys< at >public.gmane.org>

All these guys displayed the patience of a million saints. Of extraordinary note is Kevin who came to the table with 20+ years as a programmer and has his own Digital Video Studio. Kevin taught me so darn much about his-res graphics and even more about Xcode. For example, he talked about png-crush (I'm embarrassed to ask, so I'll look around for its meaning). He taught me about making the project settings independent of a particular directory, in short, not hard-wiring the location.

Let's hear a ear-splitting round of applause for these 4 guys … I didn't hear you … oh, come on, you can do better than that! That's better.

I think I'm ready to throw in the towel - I really need help here

John Love — 2012-01-24T13:06:25

I've got my universal iApp (entitled "Love Song to America") all ready (started in Sept, 2011), except I've got quite a few .png graphics whose x2 version are very, very pixelated.

Furthermore, it will never get to the app store because my app has been rejected because of the pixelation I've just mentioned.

I do coding and have learned a helluva lot from you over the years (notably Graham Cox).  I have next to zero skill using Photoshop, etc. Most of my graphics are from screen shots that are more than ample for my website:

http://webpages.charter.net/jolove/usa

For my UITabBar icons I have used the free-version of the famous glyph icons and so I'm good for 9 out the total of 12 UITabBar icons.  For the png graphics on my many UIView's, however, it is clear to me that these graphics almost need total re-building for my universal app.

Yes, my app will be free; however, within reason, I am very willing to pay someone for such efforts.

The help I seek comes in 2 varieties:

(1) John, use this graphics app, do these 3-or-whatever things on your png graphics and bingo!

enhancing Force Quit or improving user-driven diagnostics

John Hawkinson — 2012-01-15T16:18:18

I've had a number of cases recently where I would like to encourage
some of my site's users to SIGABRT processes when they hang (so I can
at least have a crash report to take to a software vendor or stare at
myself, and maybe even a core dumps), but some of my users really
really like to Force Quit when things go wrong (and they're in a hurry).

While trying to modify user behavior is hard, I'd like to give them the
option to send SIGABRT and make it as easy as possible.

Is it possible to trap the Cmd-Opt-Escape sequence and redirect it to
a custom implementation?

Is there any prior art in this space?


I understand that it currently goes to loginwindow, and I assume there
is no hope in modifying loginwindow to add one more
button. [Hmm. Maybe I could modify loginwindow to send SIGABRT instead
of SIGKILL though? That might be unwise. ]

I know I can disable force quit entirely with the Kiosk API and
kUIOptionDisableForceQuit. But that's not very palatable.
(Though I suppose if I could disable it and then bind another key to
invoke my custom app, that would not be so bad).

Is it practical to use a Quartz Event Tap for this purpose?

Thoughts appreciated.

(It's not for "my app" so I suppose this is a sysadmin-ish kind of
question, but I'm certainly prepared to write code to accomplish it.)


TANGENT:
Another thing I would like to do is to take a screenshot of app state
at the time a crash happens. Does anyone have any experience extending
ReportCrash to do something like that?

Perhaps it is as easy as a shell-script wrapper.

It is amusing to me that my ability to take screenshots of app state
at crash time improves exponentially when core dumps are enabled.
When you have tends of seconds to realize the app is crashing, taking
a screenshot is pretty easy. And they can be invaluable in debugging
complex problems.


Thanks, all.

When to update NSFindPboard

Christiaan Hofman — 2011-12-21T18:46:29

What are the appropriate times to set NSFindPboard?

I can find really very little information about this in the documentation, basically nothing, and the only sample I could find is very limited in this respect, too little to give any useful information.

Also, looking at various Apple applications I can actually find several different behaviors.

So here is my setting. A window containing searchable information, which can have a scope bar containing a search field. The scope bar can be added and removed, and searching can be done through performFindPanelAction: or buttons (more precisely an segmented control). So similar to Xcode 3's edit windows.

So there are a few things that can happen:
1. find (replace) actions, including search field action (Enter)
2. set find string (NSFindPanelActionSetFindString)
3. add scope bar
4. remove scope bar
5. window becomes key
6. window resigns key

Would the correct behavior be to update the NSFindPboard in 1, 2, 4, 5, 6? Or perhaps only when the find string is not empty? Or only at a subset of these events? Or did I forget about events that should trigger updating NSFindPboard?

thanks,
Christiaan

Calling commitEditing text field loses focus

Christiaan Hofman — 2011-12-20T13:14:30

I have a text field whose value is bound through an NSObjectController. Before performing certain actions I call -commitEditing on that object controller to make sure I have the current value from the text field. What I notice is that if there are any uncommitted changes to the text, the text field loses focus due to this call. This is certainly not what I want, I just want to commit the edit. I also don't recall this to happen in the past, but I am not sure for how long this has been going on. Also, the focus is not lost when the text had not changed since the last commit. To me this sounds like a bug. Can anyone confirm this is a bug, or tell me why this would make sense? Or tell me whether there is some kind of setting to change this behavior?

thanks,
Christiaan

When is editWithFrame:... used?

Christiaan Hofman — 2011-12-04T23:18:35

Can anyone tell me when NSTextFieldCell's editWithFrame:... method is used? In my testing all ways of editing I have tried always go through selectWithFrame:... and never use editWithFrame:.... I need to know for a subclass whether I need to override this method, but for that I need to test it. But when it's not used it's not tested...

thanks,
Christiaan
