  • Custom TableViewCell with TextField and first responder

    - by Robb
    I have a custom TableView cell that contains a TextField and I want it to become the first responder as soon as the view is shown but [textcell.textfield becomeFirstResponder] does not work. I know it's because it's a custom cell in another class and I even tried it there and it didn't work. Anyone know how to pull this off? Thanks...

  • Why is my NSMutableArray returning nill?

    - by lampShade
    I have a very simple task: add the contents of a textField to an NSMutableArray.The Problem is the array is returning nill. I believe that it has something to do with the fact that the array I'm using is declared as an instance variable. /* IBOutlet NSTextField *textField; IBOutlet NSTabView *tableView; IBOutlet NSButton *button; NSMutableArray *myArray; */ #import "AppController.h" @implementation AppController -(IBAction)addNewItem:(id)sender { NSString *string = [textField stringValue]; NSLog(@"%@",string); [myArray addObject:string]; NSLog(@"%d",[myArray count]);//this outputs 0 why is that? }

  • Using TagLib as a framework in XCode: C++ header <string> not found

    - by david
    I have build TagLib as a framework using this: https://github.com/rahvin/TagLib.framework. I dragged the produced framework into my XCode Project and now it says: "String: No such file or directory" on including <TagLib/TagLib.h>. I've never done this before. It seems as XCode does not include the c++ headers by default ?! (Or is string not a c++ default header?!) Note: The taglib headers are included right. <string> is the problem

  • Dismissing UIImagePickerController from UITabBarController

    - by Dave
    I have a tab bar application whereby one tab uses a navigation controller to move through a series of views. On the final view, there is a button to add a photo, which presents a UIImagePickerController. So far, so good - however when I finish picking the image, or cancel the operation, the previous view is loaded, but without the tab bar. I'm sure I'm missing something elementary, but any suggestions on how to properly release the UIImagePickerController would be much appreciated. The code is as follows: ImagePickerViewController *aController = [[ImagePickerViewController alloc]; initWithNibName:@"ImagePickerViewController" bundle:[NSBundle mainBundle]]; [self presentModalViewController:aController animated:YES]; [aController release]; //viewDidLoad self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; if([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]){ imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera; } else { imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } [window addSubview:imagePickerController.view]; //ImagePickerViewController imagePickerControllerDidCancel - FinalViewController is the last view in the stack controlled by a navigation controller which contains the button to present the UIImagePickerController [picker dismissModalViewControllerAnimated:YES]; FinalViewController *aController = [[FinalViewController alloc initWithNibName:@"FinalViewController" bundle:[NSBundle mainBundle]]; [picker presentModalViewController:aController animated:YES]; [aController release];

  • How do I draw a proper parallelogram that can be animated on iPhone?

    - by Robert Kosara
    I'm trying to do something very simple: I need some parallelograms in my program. These are attached to other objects, all of which are UIViews. It's important that I be able to animate these, since the objects they are attached to can also be animated. I've figured out how to use the transform in UIView/CALayer to do this, but the problem is that these sheared UIViews don't look very nice: there is no anti-aliasing of the edges. Is there some other way to do this? I would like to use UIViews, since I also use them for user interaction and animation is so much easier than drawing by hand. I don't want to use OpenGL for this.

  • Working with images (CGImage), exif data, and file icons

    - by Nick
    What I am trying to do (under 10.6).... I have an image (jpeg) that includes an icon in the image file (that is you see an icon based on the image in the file, as opposed to a generic jpeg icon in file open dialogs in a program). I wish to edit the exif metadata, save it back to the image in a new file. Ideally I would like to save this back to an exact copy of the file (i.e. preserving any custom embedded icons created etc.), however, in my hands the icon is lost. My code (some bits removed for ease of reading): // set up source ref I THINK THE PROBLEM IS HERE - NOT GRABBING THE INITIAL DATA CGImageSourceRef source = CGImageSourceCreateWithURL( (CFURLRef) URL,NULL); // snag metadata NSDictionary *metadata = (NSDictionary *) CGImageSourceCopyPropertiesAtIndex(source,0,NULL); // make metadata mutable NSMutableDictionary *metadataAsMutable = [[metadata mutableCopy] autorelease]; // grab exif NSMutableDictionary *EXIFDictionary = [[[metadata objectForKey:(NSString *)kCGImagePropertyExifDictionary] mutableCopy] autorelease]; << edit exif >> // add back edited exif [metadataAsMutable setObject:EXIFDictionary forKey:(NSString *)kCGImagePropertyExifDictionary]; // get source type CFStringRef UTI = CGImageSourceGetType(source); // set up write data NSMutableData *data = [NSMutableData data]; CGImageDestinationRef destination = CGImageDestinationCreateWithData((CFMutableDataRef)data,UTI,1,NULL); //add the image plus modified metadata PROBLEM HERE? NOT ADDING THE ICON CGImageDestinationAddImageFromSource(destination,source,0, (CFDictionaryRef) metadataAsMutable); // write to data BOOL success = NO; success = CGImageDestinationFinalize(destination); // save data to disk [data writeToURL:saveURL atomically:YES]; //cleanup CFRelease(destination); CFRelease(source); I don't know if this is really a question of image handling, file handing, post-save processing (I could use sip), or me just being think (I suspect the last).

  • Storing arrays in NSUserDefaultsController

    - by neoneye
    Currently I use NSUserDefaults and I'm interested in using NSUserDefaultsController, so that I get notifications when things change. Below is my current code. items = /* NSArray of MYItem's */; NSData* data = [NSKeyedArchiver archivedDataWithRootObject:items]; [[NSUserDefaults standardUserDefaults] setObject:data forKey:kMYItems]; How should I rework my code to store items in NSUserDefaultsController ? Is NSKeyedArchiver the smartest way to store arrays? @interface MYItem : NSObject <NSCoding> { NSString* name; NSString* path; } @property (copy) NSString* name; @property (copy) NSString* path; @end @implementation MYItem @synthesize name, path; -(void)encodeWithCoder:(NSCoder*)coder { [coder encodeObject:name forKey:@"name"]; [coder encodeObject:path forKey:@"path"]; } -(id)initWithCoder:(NSCoder*)coder { [super init]; [self setName:[coder decodeObjectForKey:@"name"]]; [self setPath:[coder decodeObjectForKey:@"path"]]; return self; } @end

  • Adding help button for each window

    - by Miraaj
    Hi all, I have found that user can associate help with his application using Help Viewer. Users typically launch Help Viewer by choosing the application help item from the Help menu, or by typing a query in the Spotlight For Help text field in the Help menu. I have some different requirement: I want to associate component specific help to my application, means that there will be a small '?' marked icon at bottom left corner of a window and when user clicks it, appropriate help page will open. This case is similar to 'print' panels where there is a small '?' icon. Can anyone suggest me some way to accomplish it, if it is possible? Thanks, Miraaj

  • How to auto-scroll UITableView?

    - by Sheehan Alam
    I am trying to do something interesting. I am pulling some JSON data and populating cells in a UITableView. How can I make the UITableView scroll ever second or so? I want to give the effect that as new data is coming in, the table is scrolling, so it is streaming. Any ideas?

  • iPhone OS: Tap status bar to scroll to top doesn't work after remove/add back

    - by avocade
    Using this method to hide the status bar: [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; When setting "hidden" back to NO, the tap-to-scroll-to-top (in UIWebView, UITableView, whatever) doesn't work any more, and requires a restart of the app to get the functionality back. Is this a bug (I filed a rdar anyhow) or have I missed a step? Should I perhaps expect this behavior since the statusBar "loses touch" somehow with the respective view?

  • Blending Three Images into Graphics Context Using Alpha Blend Mode kBlendModeOverlay

    - by steganous
    Does kCGBlendModeOverlay not work exactly like Photoshop's Overlay blending mode? I'm trying to overlay three images into a graphic context via: [uiimageGreen drawAtPoint:CGPointMake(x, y) blendMode:kCGBlendModeOverlay alpha:1.0]; [uiimageRed drawAtPoint:CGPointMake(x, y) blendMode:kCGBlendModeOverlay alpha:1.0]; [uiimageBlue drawAtPoint:CGPointMake(x, y) blendMode:kCGBlendModeOverlay alpha:1.0]; In the end, if I overlay just two of the three, the result is much closer to my desired output color in places where both images intersect. Adding the third image, however, causes the first-drawn image's color to be dominant in the resulting mix of colors. (e.g. in the above code, green comes out dominant, when the result should actually be white) Do you get the same result if you try?

  • UIImagePickerController camera preview is portrait in landscape app

    - by Jane Sales
    In my landscape-only iPhone application, I launch a UIImagePickerController to take a photo, but the live image displayed from the camera is in portrait orientation, with blank space around it. The image is rotated. Once the camera button is pressed, the preview is very messy, with most of the preview off screen, and views not correctly aligned. Apple has acknowledged that this is defect, and is working on it. My question is, does anyone have a work-around (legal or illegal) that would allow me to get this working now. I wouldn't release to the App Store with an illegal fix, but I would have a much better app for user testing - currently the camera is pretty much unusable in landscape. I will attach a simple test project and images if I can. Edit - just to clarify, the image I get is correctly landscape. I want the camera & preview UIs to look right!

  • CAShapeLayer slowing down interface rotation

    - by MrMage
    Hi, I am trying to move some custom drawing code from a view into a CAShapeLayer, which then get added as a sublayer to the original view's CALayer. This also works well, but when rotating the device, the animation starts to stutter, e.g. you just see the frame in the original orientation and then the final orientation, with at most one frame in between - not smooth at all. Slide-in and slide-out animations of the corresponding UIViewController are a bit jerky, too (but not that much). All the CAShapeLayer has in its path is one CGPathAddRect, it is set to be opaque, its opacity is 1.0f and the fillColor is set to opaque blue. When drawing the path directly in the views drawRect method, however, the animation is smooth. So I suppose it has something to do with the CAShapeLayer being animated during the rotation. Could you tell me how to either get rid of those jerkiness or just hide the CAShapeLayer when animating? Getting back to just draw CGPaths directly is not an option to me because I rely on the ability of CAShapeLayer to animate its path (it is not animated in my tries with rotating the view). /update: this also happens when the rotating UIViewControllers view contains a view with a subclass of CAGradientLayer as its layerClass (e.g. a view with a gradient layer as background). Cheers MrMage

  • Unselected UIPickerView value

    - by morticae
    According to the documentation, if a UIPickerView has no selected value, the expected return from selectedRowInComponent: should be: "A zero-indexed number identifying the selected row, or -1 if no row is selected." However, if I check the value the very line after initializing one, its value is 0. Even if I then manually set it to -1, it still returns 0. I would like to be able to detect whether the user has chosen a value yet or not, without recording it in a local variable. Is this possible? example: UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 46.0, 320.0, 216.0)]; [picker selectRow:-1 inComponent:0 animated:NO]; NSLog(@"SELECTED %d", [picker selectedRowInComponent:0]); expected output: SELECTED -1 actual output: SELECTED 0

  • MKReverseGeocoder delegate location?

    - by fuzzygoat
    I have a quick question regarding memory management that I am not quite sure about. I currently have a locationManager delegate that calls locationManager:didUpdateToLocation:fromLocation when it resolves the device location. My question is I am looking at adding ReverseGeoCoding after I have obtained the [newLocation coordinate] but am unsure about doing the alloc here, as each time locationManager:didUpdateToLocation:fromLocation gets called I will be alloc-ing a new MKReverseGeoCoder? // LOCATION -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // GeoCoding: MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:[newLocation coordinate]]; [geoCoder setDelegate:self]; [geoCoder start]; [self foundLocation]; } Can anyone point me in the right direction with regards to this? I did try doing the alloc in application:didFinishLaunchingWithOptions: but then realised I did not have access to [newLocation coordinate]. many thanks gary

  • How to animate the drawing of a CGPath?

    - by Jordan Kay
    I am wondering if there is a way to do this using Core Animation. Specifically, I am adding a sub-layer to a layer-backed custom NSView and setting its delegate to another custom NSView. That class's drawInRect method draws a single CGPath: - (void)drawInRect:(CGRect)rect inContext:(CGContextRef)context { CGContextSaveGState(context); CGContextSetLineWidth(context, 12); CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, 0, 0); CGPathAddLineToPoint(path, NULL, rect.size.width, rect.size.height); CGContextBeginPath(context); CGContextAddPath(context, path); CGContextStrokePath(context); CGContextRestoreGState(context); } My desired effect would be to animate the drawing of this line. That is, I'd like for the line to actually "stretch" in an animated way. It seems like there would be a simple way to do this using Core Animation, but I haven't been able to come across any. Do you have any suggestions as to how I could accomplish this goal?
