  • How to install pyobjc on SnowLeopard's non-default python installation

    - by IgorJ
    Hi everybody. I'm having problems installing pyobjc on SnowLeopard. It came with python 2.6 but I need 2.5 so I have installed 2.5 successfully. After that I have installed xcode. After that I have installed pyobjc with "easy_install-2.5 pyobjc" But when I start my python 2.5 and from cmd line try to import Foundation, it says "no module named Foundation" Of course, from 2.6 everything works fine. How do I find out what's wrong and what should i do?

  • Wishlist for Objective-C IDE/Xcode ?

    - by Null Pointer
    My company is evaluating the possibility of developing set of tools for Objective-C extending Xcode default functionality(basically we are thinking about providing better navigation,semantic search, more refactorings, quick fixes, improved code completion (visual assist inspired). So we would like to ask XCode/Objective-C developers: Do you feel that you are missing some features in XCode? What is your wish list? Are you considering the possibility of using addons to Xcode which are not created by Apple? Would you be willing to pay for these addons, or would you only consider free solutions?

  • Can I embed a custom font in an iPhone application?

    - by Airsource Ltd
    I would like to have an app include a custom font for rendering text, load it, and then use it with standard UIKit elements like UILabel. Is this possible? I found these links: http://discussions.apple.com/thread.jspa?messageID=8304744 http://forums.macrumors.com/showthread.php?t=569311 but these would require me to render each glyph myself, which is a bit too much like hard work, especially for multi-line text. I've also found posts that say straight out that it's not possible, but without justification, so I'm looking for a definitive answer. EDIT - failed -[UIFont fontWithName:size:] experiment I downloaded Harrowprint.tff (downloaded from here) and added it to my Resources directory and to the project. I then tried this code: UIFont* font = [UIFont fontWithName:@"Harrowprint" size:20]; which resulted in an exception being thrown. Looking at the TTF file in Finder confirmed that the font name was Harrowprint. EDIT - there have been a number of replies so far which tell me to read the documentation on X or Y. I've experimented extensively with all of these, and got nowhere. In one case, X turned out to be relevant only on OS X, not on iPhone. Consequently I am setting a bounty for this question, and I will award the bounty to the first person who provides an answer (using only documented APIs) who responds with sufficient information to get this working on the device. Working on the simulator too would be a bonus. EDIT - it appears that the bounty auto-awards to the answer with the highest nunber of votes. Interesting. No one actually provided an answer that solved the question as asked - the solution that involves coding your own UILabel subclass doesn't support word-wrap, which is an essential feature for me - though I guess I could extend it to do so.

  • Converting NSData to an NSString representation is failing

    - by Ricky D'Amelio
    Hi there. I have an NSData object which I am trying to turn into an NSString using the following line of code: NSString *theData = [[NSString alloc] initWithData:photo encoding:NSASCIIStringEncoding]; Unfortunately I am getting the following result, instead of my desired binary output (can I expect a binary output here?); ÿØÿà I'd appreciate any help.

  • iPhone - stdint.h file not found!

    - by Mike
    I am dealing with a project designed for iPhone OS 2.0 and I am intending to keep compatibility with this version while offering new OS 3.x functionality. When I set the base SDK to iPhone OS 3.1.3 and Target OS for 2.0, Xcode gives me this error during compilation. 'stdint.h' file not found /Developer/usr/lib/clang/1.0.1/include/stdint.h:32:16: fatal error: 'stdint.h' file not found The strange thing is that the file is there, on the path it says it is not. if I set the target OS for 3.x the problem vanishes. how to solver that? thanks for any help.

    In my code below, CustomWindow is a subclass of NSWindow. CustomWindow *window = [[CustomWindow alloc] init]; if (![NSBundle loadNibNamed:@"NibName" owner:window]) [window center]; // doesn't work How do you get a pointer to control your XIB after you load it so you can do things such as centering the XIB? What am i doing wrong here?

  • Multiple undo managers for a text view

    - by Rui Pacheco
    Hi, I've a text view that gets its content from an attributed string stored in a model object. I list several of these model objects in a drawer and when the user clicks on one the text view swaps its content. I now need to also swap the undo manager for the text view. I initialise an undo manager on my model object and use undoManagerForTextView to return it to the text view, but something's not quite right. Strategically placed logging statements show me that everything's working as planned: on startup a new model object is initialised correctly and a non-null undo manager is always pulled by the text view. But when it comes to actually doing undo, I just can't get the behaviour I want. I open a window, type something and press cmd+z, and undo works. I open a window, type something, select a new model on the table, type something, go back to the first model and try to undo and all I get is a beep. Something on the documentation made me raise an eyebrow, as it would mean that I can't have undo with several model objects: The default undo and redo behavior applies to text fields and text in cells as long as the field or cell is the first responder (that is, the focus of keyboard actions). Once the insertion point leaves the field or cell, prior operations cannot be undone.

  • unarchiveObjectWithFile retain / autorelease needed?

    - by fuzzygoat
    Just a quick memory management question if I may ... Is the code below ok, or should I be doing a retain and autorelease, I get the feeling I should. But as per the rules unarchiveObjectWithFile does not contain new, copy or alloc. -(NSMutableArray *)loadGame { if([[NSFileManager defaultManager] fileExistsAtPath:[self pathForFile:@"gameData.plist"]]) { NSMutableArray *loadedGame = [NSKeyedUnarchiver unarchiveObjectWithFile:[self pathForFile:@"gameData.plist"]]; return loadedGame; } else return nil; } or -(NSMutableArray *)loadGame { if([[NSFileManager defaultManager] fileExistsAtPath:[self pathForFile:@"gameData.plist"]]) { NSMutableArray *loadedGame = [[NSKeyedUnarchiver unarchiveObjectWithFile:[self pathForFile:@"gameData.plist"]] retain]; return [loadedGame autorelease]; } else return nil; } gary

  • Date since 1600 to NSDate?

    - by Steven Fisher
    I have a date that's stored as a number of days since January 1, 1600 that I need to deal with. This is a legacy date format that I need to read many, many times in my application. Previously, I'd been creating a calendar, empty date components and root date like this: self.gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar ] autorelease]; id rootComponents = [[[NSDateComponents alloc] init] autorelease]; [rootComponents setYear: 1600]; [rootComponents setMonth: 1]; [rootComponents setDay: 1]; self.rootDate = [gregorian dateFromComponents: rootComponents]; self.offset = [[[NSDateComponents alloc] init] autorelease]; Then, to convert the integer later to a date, I use this: [offset setDay: theLegacyDate]; id eventDate = [gregorian dateByAddingComponents: offset toDate: rootDate options: 0]; (I never change any values in offset anywhere else.) The problem is I'm getting a different time for rootDate on iOS vs. Mac OS X. On Mac OS X, I'm getting midnight. On iOS, I'm getting 8:12:28. (So far, it seems to be consistent about this.) When I add my number of days later, the weird time stays. OS | legacyDate | rootDate | eventDate ======== | ========== | ==========================|========================== Mac OS X | 143671 | 1600-01-01 00:00:00 -0800 | 1993-05-11 00:00:00 -0700 iOS | 143671 | 1600-01-01 08:12:28 +0000 | 1993-05-11 07:12:28 +0000 In the previous release of my product, I didn't care about the time; now I do. Why the weird time on iOS, and what should I do about it? (I'm assuming the hour difference is DST.) I've tried setting the hour, minute and second of rootComponents to 0. This has no impact. If I set them to something other than 0, it adds them to 8:12:28. I've been wondering if this has something to do with leap seconds or other cumulative clock changes. Or is this entirely the wrong approach to use on iOS?

  • Finding source of over release

    - by Benedict Lowndes
    Hi, I'm consistently seeing the same message sent in as a crash report from users of an app. It's clear that an object is being over-released but I'm unable to replicate it and I'm looking for tips on tracing the source of it. The relevant section from the crash report shows this: Application Specific Information: objc_msgSend() selector name: release Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x90892edb objc_msgSend + 27 1 com.apple.CoreFoundation 0x95ec5a40 __CFBasicHashStandardCallback + 384 2 com.apple.CoreFoundation 0x95ec564e __CFBasicHashDrain + 478 3 com.apple.CoreFoundation 0x95ead6f1 _CFRelease + 353 4 com.apple.CoreFoundation 0x95eda0ed _CFAutoreleasePoolPop + 253 5 com.apple.Foundation 0x97ecedd6 NSPopAutoreleasePool + 76 6 com.apple.Foundation 0x97ececfe -[NSAutoreleasePool drain] + 130 7 com.apple.AppKit 0x9211255f -[NSApplication run] + 1013 8 com.apple.AppKit 0x9210a535 NSApplicationMain + 574 9 TheApp 0x000020a6 start + 54 I've used zombies and leaks, but haven't seen anything there. I've gone through the code and can't see it. What's the next step? Are there any hints I can discern from this information as to the source of it? Does the fact that this nearly exact same crash report is coming in repeatedly mean that it's the same object that's being over released, or because this is referring to the autorelease pool mean it could be any object? Does the reference to _CFRelease mean it's a Core Foundation object that's being over released?

  • How to troubleshoot deallocation of object in uitableview?

    - by 4thSpace
    I have a table view with tall cells. About 300 in height. The cells are custom and have an associated nib. In cellForRowAtIndexPath, I access an object in an array using indexPath.row. The object has properties, which I assign to labels on the custom cell. This works fine for the first two cells. Once I scroll enough for the third cell to get created, the app crashes. I have NSZombieEnabled set and here is the output: 2010-04-19 21:48:13.360 MyApp[54463:207] *** -[CALayer release]: message sent to deallocated instance 0xfc4e50 (gdb) continue 2010-04-19 21:48:18.382 MyApp[54463:207] *** NSInvocation: warning: object 0xfc4e50 of class '_NSZombie_CALayer' does not implement methodSignatureForSelector: -- trouble ahead 2010-04-19 21:48:18.383 MyApp[54463:207] *** NSInvocation: warning: object 0xfc4e50 of class '_NSZombie_CALayer' does not implement doesNotRecognizeSelector: -- abort (gdb) continue Program received signal: “EXC_BAD_ACCESS”. (gdb) I'm not sure what is deallocated. How can I trace this to the source?

  • iPhone "slide to unlock" animation

    - by Russ
    Any ideas as to how Apple implemented the "slide to unlock" (also, "slide to power off" is another identical example) animation? I thought about some sort of animating mask - but masking is not available on the iPhone OS for performance reasons. Is there some private API effect (like SuckEffect) that they might have used? A spotlight type of effect? Some Core Animation thing? Edit: It's definitely not a series of stills. I've seen examples of being edit a plist value or something and customize the string on jailbroken iphones.

  • Image "moves" when varying heightForRowAtIndexPath in UITableViewCell.

    - by Kalle
    I have a table view with varying height, as defined in the heightForRowAtIndexPath. For some very odd reason, the image is "indented" to the right based on the height; if the height is low enough, the image is stuck to the left side of the cell, but as the height increases, the image for said cell is shifted rightward compared to other rows. The result of this is a very poor looking list, with images floppily laid out in a zig-zag pattern depending on the height of each individual row. The problem is revealed by this simple example: - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return (indexPath.row+1) * 50; } Each cell is set up (simplified) as a "Subtitle" style cell with: // ... cell.textLabel.text = @"foo"; cell.detailTextLabel.text = @"bar"; cell.imageView.backgroundColor = [UIColor redColor]; // for debugging; i have images with transparent bg cell.imageView.image = anImageThatIs55x50pixelsBig; return cell; Any ideas? My head bleeds from the wall-love-affair. Edit: uploaded a screen which displays this. The "image" is just a screenshot of a tiny area of the screen which makes it look a little weird, but you get the picture I'm sure: http://img28.imageshack.us/img28/549/screenshot20100311at172.png

  • TTNavigator doesn't use existing navigation bar (iPhone)

    - by user220770
    I am using the three20 framework in one view controller of my App. I create TTNavigator object and open a url which works fine. The problem is that TT creates it's own navigation bar and does not use the existing bar. There is no back button on the new nav bar so I cannot go back to my previous view controller. Has anybody run into this issue? Any ideas on how to fix (besides not using three20)? Thanks

  • Getting a WebView to act exactly like Safari

    - by Kelly McDonald
    (edited to give a better description of the answer I gave) I have created a very simple browser in InterfaceBuilder consisting of a nav bar and a webview. Everything works fine except when I try to tab between input fields is the webview, the focus goes to the nav bar. I'm assuming I need to do something with the responder chain, but I haven't been able to figure out what. Any advice? Thanks, Kelly

  • Packaging a Bundle with a static library

    - by 4thSpace
    I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't be part of the target. I thought about creating a CFPluginBundle but that creates a new project. I'd loose all of my IBOutlet and IBAction references. What is the best way to reuse xibs that also have outlets and actions to specific controllers?

  • How to update a detailView in a splitViewController?

    - by pikebu
    Hello, I'm trying to update a detailView in a splitViewController. This is what I try: //Get the application delegate AppDelegate *delegate = [[UIApplication sharedApplication] delegate]; //Get the masterViewController MasterViewController *master = [delegate.splitViewController.viewControllers objectAtIndex:0]; This seems to work fine so far. Then I try to update a label in the detailViewController by doing this: master.detailViewController.myLabel.text = "someText"; But this doesn't work. (ignore the missing at sign in front of the "someText" - I have it, but it seems it's not allowed to put it in this forum.) So how is the right way to access the outlets of in the detailView? Thanks for help.

  • Callback for camera shutter open event

    - by Raj
    Hi all, I have been working around in UIImagePickerController and am struck with a problem where I need to get the precise moment when the camera shutter opens in UIImagePickerController when the source type is set to camera (UIImagePickerControllerSourceTypeCamera). I have done some googling around and have realized that no one had such strange requirement! I looked around the docs of UIImagePickerController and UIImagePickerControllerDelegate hoping to get some delegate method / callback indicating the camera shutter open event, but did not find any. Any suggestions? Thanks for any help, Raj Pawan
