  • what's the right way to cause a subview to redraw when the device orientation changes?

    - by RobertL
    I have a view controller with a view and one subview. When the device orientation changes the view auto-redraws but the subview doesn't. If I explicitly do [subview setNeedsDisplay] it redraws but I don't have a logical place to put that call in my code. And, since I don't have to explicitly tell the view to redraw, it seems counter-intuitive to tell the subview to redraw. Is there a way to make the subview auto-redraw when the view redraws?

  • Why do I get "2010-01-01 00:00:00 +900" from "2010-12-31 15:00:00 +000"?

    - by mikezang
    I have NSDate, it will be shown as below if I used NSLog(@"%@", date.description); 2010-12-31 15:00:00 +0000 it will be shown as if I used NSLog(@"%@", [date descriptionWithLocale:[[NSLocale currentLocale] localeIdentifier]]); Saturday, January 1, 2011 12:00:00 AM Japan Standard Time But it will be show as below if I used NSLog(@"%@", [date formattedDateString]); 2010-01-01 00:00:00 +0900 Where do I make mistake? (NSString *)formattedDateString { return [self formattedStringUsingFormat:@"YYYY-MM-dd HH:mm:ss ZZZ"]; } (NSString *)formattedStringUsingFormat:(NSString *)dateFormat { NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:dateFormat]; NSString *ret = [formatter stringFromDate:self]; [formatter release]; return ret; }

  • numeric sort with NSSortDescriptor for NSFetchedResultsController

    - by edziubudzik
    I'm trying to numerically sort data that's displayed in a UITableView. Before that I used such a sort descriptor: sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES selector:@selector(caseInsensitiveCompare:)]; now I'd like to use block to sort this numerically like this: sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) { return [((NSString *)obj1) compare:(NSString *)obj2 options:NSCaseInsensitiveSearch | NSNumericSearch]; }]; but it sorts the data incorectly causing conflict with section names in NSFetchedResultsController. So I tryed to immitate the old sorting with a comparator block - just to be sure that the problem is not caused by numeric comparison. The problem is that those lines: sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) { return [((NSString *)obj1) caseInsensitiveCompare:(NSString *)obj2]; }]; also cause the same error and I don't see why they won't sort the data in the same way the first method did... Any ideas?

  • Added CAGradientLayer, getting this in my UIView dealloc: [CALayer release]: message sent to deallocated instance

    - by developerdoug
    Here there, I have a custom UIView. This view acts as a activity indicator but as label above the UIActivityIndicatorView. In the init, I add a CAGradientLayer. I allocate and initialize it and insert it at index 0 as a sublayer of the UIView layer property. In my dealloc method was called, I received a message in the console: - [CALayer release]: message sent to deallocated instance. My code: @interface LabelActivityIndicatorView () { UILabel *_label; UIActivityIndicatorView *_activityIndicatorView; CAGradientLayer *_gradientLayer; } @end @implementation LabelActivityIndicatorView //dealloc - (void) dealloc { [_label release]; [_activityIndicatorView release]; //even tried to remove the layer [_gradientLayer removeFromSuperLayer]; [_gradientLayer release]; [super dealloc]; } // init - (id) initWithFrame:(CGRect)frame { if ( (self = [super initWithFrame:frame]) ) { // init the label // init the gradient layer _gradientLayer = [[CAGradientLayer alloc] init]; [_gradientLayer setBounds:[self bounds]]; [_gradientLayer setPosition:CGPointMake(frame.size.width/2, frame.size.height/2)]; [[self layer] insertSublayer:_gradientLayer atIndex:0]; [[self layer] setNeedsDisplay]; } return self; } @end Anyone have any ideas. Since I'm allocating and initializing the gradient layer I'm responsible for releasing it. I should be able to alloc and init and assign to some ivar. Perhaps I should create a property with retain on it. Thanks,

  • Load local Html file doesn't refer the js file in UIWebView

    - by Hero Vs Zero
    I am working with UIWebView project and I want to load an HTML file from a project resource. It is working fine when I run from the URL, but when I view the HTML file locally, JS files are not loaded. Loading the local HTML local file doesn't refer to js files in UIWebView. Here's my code to load the HTML file project local resource and does't refer the js file: NSString *path = [[NSBundle mainBundle] pathForResource:@"textfile" ofType:@"txt"]; NSError *error = nil; NSString *string = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error]; NSString *path1 = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL = [NSURL fileURLWithPath:path1]; NSLog(@"%@ >>> %@",baseURL,path); [webview loadHTMLString:string baseURL:baseURL]; This code doesn't find JS files in UIWebView, even though it loads image files from the project resource successfully.

  • Custom URL for the Birdhouse app

    - by bryanjclark
    I'd like to figure out the custom URL scheme for the Birdhouse iPhone app, but there doesn't seem to be any documentation. Birdhouse is an app to store drafts for Twitter. I'd like to send it a string of text, and I know that it's possible: Birdhouse responds to the URL birdhouse:/// The Twitter app sends drafts to Birdhouse if it's installed on your phone. I've figured out the birdhouse:/// part, but how do I send the text?

  • Errors in UILabel

    - by Todd Davies
    I'm trying to use the FXlabel when following this (Adding a gradient label section) tutorial. This is some of the code inside my viewDidLoad method: self.logoLabel = [[FXLabel alloc] initWithFrame:CGRectMake(14, 11, 280, 87)]; [logoLabel setFont:[UIFont boldSystemFontOfSize:45]]; [logoLabel setTextColor:[UIColor whiteColor]]; [logoLabel setShadowColor:[UIColor blackColor]]; [logoLabel setShadowOffset:CGSizeMake(0, 2)]; [logoLabel setTextAlignment:UITextAlignmentCenter]; [logoLabel setBackgroundColor:[UIColor clearColor]]; [logoLabel setText:@"Attorney Biz"]; [logoLabel setGradientStartColor:[UIColor colorWithRed:163.0/255 green:203.0/255 blue:222.0/255 alpha:1.0]]; [logoLabel setGradientEndColor:[UIColor whiteColor]]; Unfortnuately, I get an error "No visible @interface for 'UILabel' declares the selector 'setGradientStartColor'" at the second-to-last line and "No visible @interface for 'UILabel' declares the selector 'setGradientEndColor'" Can somebody explain how to remove these errors?

  • iAd banner gives warning when pushed off screen by navController

    - by James Dunay
    I have a iAd that seems to be correctly displaying but when push a new view controller into the view i get a warning from the iAd that says it has been: WARNING A banner view (0x490fd0) has an ad but may be obscured. This message is only printed once per banner view. But the ad still runs fine so should i pay attention to this? I just tried adding self.adBannerView = nil; [adBannerView release];` just before i push the viewController but i still get that error

  • How to avoid truncation of text with UITableViewCellStyleValue2

    - by Regan
    I use this code to make my UITableViewCells cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier] autorelease]; If you're unfamiliar with UITableViewCellStyleValue2, the main text is shown, and then the detail text is shown after it, generally in a different color. However, when I do this, my main text is truncated, if it is longer than a short word. I want to force it to not truncate the main text and show the entire main text, and then the detail text after it. How can I do that?

  • NSXMLParser values not being retained.

    This is similar to my previous question. I didn't get an answer, maybe by changing the question I might get an answer.

  • Why does XCode keep downloading old deleted profiles and duplicates of the same profile?

    - by Piepants
    If I refresh the profiles in XCode it: a) Pulls down ones that no longer exist. Profiles that have been deleted from the portal and are no longer there b) Pulls down multiple copies of the same profile. If I add a new device and then update the profiles to include that new device. Then XCode will pull down the new updated profile but also the same profile with an older date (even though the portal only shows one, the latest). If I delete them them XCode they re-appear. I'm having problems getting push notifications to work with an ad-hoc distrubtion and so want to ensure I am build with the latest profiles. This behaviour of XCode is irritating at least, and possibly the source of my problems at worst.

  • preventing selection on MKPointAnnotation

    - by Derek
    Is there a way to prevent an annotation in a MKMapView instance from being enabled. In other words, when the user taps the red pin on the map, is there a way to prevent it from highlighting the pin. Right now the pin turns dark when touched... Edit: I'm using the following code to return the MKPinAnnotationView // To future MKMapView users - Don't forget to set _mapView's delegate _mapView.delegate = self; _annotation = [[MKPointAnnotation alloc] init]; _annotation.coordinate = myLocation; [_mapView addAnnotation:_annotation]; -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{ MKPinAnnotationView *pin = [[MKPinAnnotationView alloc] initWithAnnotation:_annotation reuseIdentifier:@"id"]; pin.enabled = NO; return pin; }

  • Using resources with the same name in Xcode

    - by Roberto
    Is there a way to add multiple resources with the same name to an Xcode project and have 1 of them take priority over the others? Example: I added 2 files, both called icon.png, to an Xcode project. They are on different folders in the file system (Folder1/icon.png and Folder2/icon.png) and on different groups in Xcode. Is there a way to tell Xcode to have Folder2/icon.png take priority over Folder1/icon.png? And if only 1 icon.png exists, then use that one. Thanks. EDIT (2010-12-23): You can have multiple files with the same name in an Xcode project even if they are not in separate folder references, but they are in separate groups. Once compiled, the app bundle (which will be flat with no folders in it), will only have one copy of the file (icon.png). How do you pick which copy of the file to use? I was told that you can do this for BlackBerry. It works something like this: The compiler will go down the list of files in the project and start adding them to the app bundle. If it sees a duplicate, it will overwrite it (or not), so the files at the bottom (or at the top) will have higher precedence and will be the final bundle.

  • Which button called the function?

    - by StoneBreaker
    I have two buttons which call the same function. That functions signature is - (IBAction)eraseTextField {...} I would like to figure out what button called the function. So I would like for the functions signature to be something like - (IBAction)eraseTextField: (id)sender {...}. Is there a way for the system to know to send the id of the calling object to a function that it calls? Thanks for the help.

  • Slide through view controllers but not with the UISwipeGestureRecognizer

    - by JoeyT
    Here is my issue, i got 5 view controllers and i can switch between them trough swipe with the UISwipeGestureRecognizer class and xcode's storyboard. So this works, but, i dont like the slide effect. I like to make it in a way so you can exactly slide the view to another by dragging it. For example, like this slider in JS: http://dimsemenov.com/plugins/royal-slider/ Can anyone send me in the right direction? I searched on the internet but i cant find any functions or tutorial on how to do this. Thanks in advance! Edit: Im not looking the scroll view. Because this will result in some white spaces when i have 3 slides vertical for slide 1 and 5 slides vertical for slide 2. Hope u guys can follow me! Edit: This is what i try to accomplish. **

  • Autorelease and properties

    - by ganuke
    I have few questions to ask about the following class #import <Cocoa/Cocoa.h> @interface SomeObject { NSString *title; } @property (retain) NSString *title; @end implementation SomeObject @synthesize title; -(id)init { if (self=[super init]) { self.title=[NSString stringWithFormat:@"allyouneed"]; } return self; } -(void)testMethod{ self.title=[[NSString alloc] init] ; } -(void)dealloc { self.title=nil; [super dealloc]; } In the .h file do we need to declare the title and sub when we add the property. is it not enough to add the @property (retain) NSString *title; line. 2.Do i need to autorelease both assignment to title in the init and testMethod. if So why? Can some one explain these things to me.

  • Localizing a plist with grouped data

    - by Robert Altman
    Is there a way to localize a plist that contain hierarchical or grouped data? For instance, if the plist contains: Book 1 (dictionary) Key (string) Name (string) Description (localizable string) Book 2 (dictionary) Key (string) Name (string) Description (localizable string) (etcetera...) For the sake of the example, the Key and Name should not be translated (and preferably should not be duplicated in multiple localized property lists). Is there a mechanism for providing localizations for the localizable Description field without localizing the entire property list? The only other strategy that came to my mind is to store a lookup key in the description field and than use that to retrieve the localized text via NSLocalizedString(...) Thanks.

  • UIButton title disappears on touch

    - by psychotik
    I want a touchable UILabel, but since that's not possible I decided to create a UIButton of type UIButtonTypeCustom. It looks how I want it to look, but when I touch it, the title disappears. I tried setting the title for state UIControlStateHighlighted but that didn't help. I know I'm doing something really silly here, but can't figure it out. I tried a few things (commented in the code below) which didn't seem to help. Here's how I'm configuring the button: UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, width, height); button.clearsContextBeforeDrawing = YES; button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; button.enabled = YES; button.hidden = NO; button.highlighted = NO; button.opaque = YES; button.selected = NO; button.userInteractionEnabled = YES; button.showsTouchWhenHighlighted = NO; [button setTitle:@"Hello World" forState:UIControlStateNormal]; button.titleLabel.font = [UIFont boldSystemFontOfSize:16]; button.titleLabel.textColor = [UIColor blackColor]; // Things I tried that didn't help //[button setBackgroundColor:[UIColor clearColor]]; //button.titleLabel.text = @"Hello World"; //[button setTitle:@"Hello World" forState:UIControlStateHighlighted]; Any ideas?

  • inserting time delay with cocos2d

    - by KDaker
    I am trying to add several labels that appear sequentially with a time delay between each. The labels will display either 0 or 1 and the value is calculated randomly. I am running the following code: for (int i = 0; i < 6; i++) { NSString *cowryString; int prob = arc4random()%10; if (prob > 4) { count++; cowryString = @"1"; } else { cowryString = @"0"; } [self runAction:[CCSequence actions:[CCDelayTime actionWithDuration:0.2] ,[CCCallFuncND actionWithTarget:self selector:@selector(cowryAppearWithString:data:) data:cowryString], nil]]; } the method that makes the labels appear is this: -(void)cowryAppearWithString:(id)sender data:(NSString *)string { CCLabelTTF *clabel = [CCLabelTTF labelWithString:string fontName:@"arial" fontSize:70]; CGSize screenSize = [[CCDirector sharedDirector] winSize]; clabel.position = ccp(200.0+([cowries count]*50),screenSize.height/2); id fadeIn = [CCFadeIn actionWithDuration:0.5]; [clabel runAction:fadeIn]; [cowries addObject:clabel]; [self addChild:clabel]; } The problem with this code is that all the labels appear at the same moment with the same delay. I understand that if i use [CCDelayTime actionWithDuration:0.2*i] the code will work. But the problem is that i might also need to iterate this entire for loop and have the labels appear again after they have appeared the first time. how is it possible to have actions appear with delay and the actions dont always follow the same order or iterations???

  • Attach GestureRecogniser to multiple imageviews

    - by AppleDeveloper
    Something strange I encountered today while attaching same gesture recogniser to multiple image views. It gets attached to only the last one, in other words, it can be attached to only one view! I had to create multiple gesture recognisers to meet my requirements. Following is what I have done. Am I doing correct? Is that's the only way to attach recognisers to the multiple imageviews? Please note that I don't want to use UITableView or UIVIew and put all imageviews in it and attach gesture recogniser to only UITableView or UIVIew. I have all image scattered and I have to detect which image is being dragged. Thanks. [imgView1 setUserInteractionEnabled:YES]; [imgView1 setMultipleTouchEnabled:YES]; [imgView2 setUserInteractionEnabled:YES]; [imgView2 setMultipleTouchEnabled:YES]; [imgView3 setUserInteractionEnabled:YES]; [imgView3 setMultipleTouchEnabled:YES]; [imgView4 setUserInteractionEnabled:YES]; [imgView4 setMultipleTouchEnabled:YES]; [imgView5 setUserInteractionEnabled:YES]; [imgView5 setMultipleTouchEnabled:YES]; [imgView6 setUserInteractionEnabled:YES]; [imgView6 setMultipleTouchEnabled:YES]; //Attach gesture recognizer to each imagviews gestureRecognizer1 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; gestureRecognizer1.delegate = self; gestureRecognizer2 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; gestureRecognizer2.delegate = self; gestureRecognizer3 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; gestureRecognizer3.delegate = self; gestureRecognizer4 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; gestureRecognizer4.delegate = self; gestureRecognizer5 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; gestureRecognizer5.delegate = self; gestureRecognizer6 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; gestureRecognizer6.delegate = self; [imgView1 addGestureRecognizer:gestureRecognizer1]; [imgView2 addGestureRecognizer:gestureRecognizer2]; [imgView3 addGestureRecognizer:gestureRecognizer3]; [imgView4 addGestureRecognizer:gestureRecognizer4]; [imgView5 addGestureRecognizer:gestureRecognizer5]; [imgView6 addGestureRecognizer:gestureRecognizer6];

  • Change UIView alpha value

Here is my code if (TransparentView == nil) { TransparentView = [[UIView alloc] initWithFrame:self.view.bounds]; TransparentView.backgroundColor = [UIColor whiteColor]; self.view = TransparentView; } start=start+appDelegate.OnOffTime; TransparentView.alpha = 0.2; float step = 1.0 / ( appDelegate.OnOffTime * 100); for (float f = 0; f < 1; f=f+step) { TransparentView.alpha = (CGFloat)(1 - f); [NSThread sleepForTimeInterval:0.01]; } Both TransparentView.alpha = 0.2 and TransparentView.alpha = (CGFloat)(1 - f) do change TransparentView.alpha, but only TransparentView.alpha = 0.2 changes real device "brightness'. What am I doing wrong?
