  • Plist won't copy to documents directory

    - by John
    I have a plist file in my resources group in xcode. I am trying to copy this into my documents directory on app launch. I am using the following code (taken from a sqlite tutorial): BOOL success; NSError *error; NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *filePath = [documentsDirectory stringByAppendingString:@"ActiveFeedsPlist.plist"]; success = [fileManager fileExistsAtPath:filePath]; if (success) return; NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingFormat:@"ActiveFeedsPlist.plist"]; success = [fileManager copyItemAtPath:path toPath:filePath error:&error]; if (!success) { NSAssert1(0, @"Failed to copy Plist. Error %@", [error localizedDescription]); } I am given the error " * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Failed to copy Plist. Error Operation could not be completed. No such file or directory'" in the console however. Any idea what is wrong? Thanks

  • Get objc_exception_throw when setting cookie with ASIHTTPRequest

    - by TuanCM
    I got objc_exception_throw when trying to set cookies for a ASIHTTPRequest request. I tried both of these but it didn't work out. ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:url]; NSMutableDictionary *properties = [[NSMutableDictionary alloc] init]; [properties setValue:@".google.com" forKey:@"Domain"]; [properties setValue:@"/" forKey:@"path"]; [properties setValue:@"1600000000" forKey:@"expires"]; NSHTTPCookie *cookie = [[NSHTTPCookie alloc] initWithProperties:properties]; [request setRequestCookies:[NSMutableArray arrayWithObject:cookie]]; or replacing initiating code for cookie with this one NSHTTPCookie *cookie = [[NSHTTPCookie alloc] init]; When I commented out the following line, everything worked fine. [request setRequestCookies:[NSMutableArray arrayWithObject:cookie]]; Can you guys tell me what the problem here!

  • custom URL scheme doesn't work! Navigon AppInteract

    - by rdesign
    Hey guys, It is really frustrating me. I used the doc provided by Navigon itself. Unfortunately it doesn't work as expected. Navigon launches, but stops at the main menu. All I do is this: NSString *myTestStr = [NSString stringWithFormat:@"navigon://App|Another place|FRA|75008|PARIS|rue de Turin|17|2.324621|48.881273"]; NSString *navigonStrEsc = [myTestStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"navigonStr: %@", navigonStrEsc); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:navigonStrEsc]]; Any ideas what is wrong with my way? thanks a lot!

  • How to use generic (NSObject) controller with subviews of a UIViewController?

    - by wanderlust
    I have a UIViewController that is loading several subviews at different times based on user interaction. I originally built all of these subviews in code, with no nib files. Now I am moving to nib files with custom UIView subclasses. Some of these subviews display static data, and I am using loadNibNamed:owner:options: to load them into the view controller. Others contain controls that I need to access. I (sort of) understand the reasons Apple says to use one view controller per screen of content, using generic controller objects (NSObjects) to manage subsections of a screen. So I need a view controller, a generic controller, a view class and a nib. How do I put this all together? My working assumptions and subsequent questions: I will associate the view class with the nib in the 'class identity' drop down in IB. The view controller will coordinate overall screen interactions. When necessary, it will create an instance of the generic controller. Does the generic controller load the nib? How? Do I define the outlets and actions in that view class, or should they be in the generic controller? How do I pass messages between the view controller and the generic controller? If anyone can point me to some sample code using a controller in this way, it will go a long way to helping me understand. None of the books or stackoverflow posts I've read have quite hit the spot yet.

  • Passing NSArray Pointer Rather Than A Pointer To a Specific Type

    - by mattmccomb
    I've just written a piece of code to display a UIActionSheet within my app. Whilst looking at the code to initialise my UIActionSheet something struck me as a little strange. The initialisation function has the following signature... initWithTitle:(NSString *)title delegate:(id UIActionSheetDelegate)delegate cancelButtonTitle:(NSString *)cancelButtonTitle destructiveButtonTitle:(NSString *)destructiveButtonTitle otherButtonTitles:(NSString *)otherButtonTitles As you can see the otherButtonTitles parameter is a pointer to a String. In my code I set it as follows... otherButtonTitles: @"Title", @"Date", nil Although this compiles fine I don't really understand how it works. My reading of the statement is that I have created an inline array containing two elements (Title and Date). How come this then compiles? I'm passing a NSArray* in place of a NSString*. I know from a little of understanding of C++ that an array is really a pointer to the first element. So is this inline array that I'm creating a C array as opposed to a NSArray? What I'm hoping to achieve is to be able to pass a static NSArray* used elsewhere in my class to the otherButtonTitles parameter. But passing the NSArray* object directly doesn't work.

  • Animating a pulsing UILabel?

    - by fuzzygoat
    I am trying to animate the color the the text on a UILabel to pulse from: [Black] to [White] to [Black] and repeat. - (void)timerFlash:(NSTimer *)timer { [[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:0.0]]; [UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{[[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:1.0]];} completion:nil]; } . [self setFadeTimer:[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerFlash:) userInfo:nil repeats:YES]]; Firstly I am not sure of my method, my plan (as you can see above) was to set up a animation block and call it using a repeating NSTimer until canceled. My second problem (as you can see above) is that I am animating from black (alpha 0) to white (alpha 1) but I don't know how to animate back to black again so the animation loops seamlessly Essentially what I want is the text color to pulse on a UILabel until the user presses a button to continue. EDIT_001: I was getting into trouble because you can't animate [UILabel setColor:] you can however animated [UILabel setAlpha:] so I am going to give that a go. EDIT_002: - (void)timerFlash:(NSTimer *)timer { [[self navTitle] setAlpha:0.5]; [UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{[[self navTitle] setAlpha:0.9];} completion:nil]; } This works (BTW: I do want it to stop which is why I hooked it up to a NSTimer so I can cancel that) the only thing is that this animates from midGray to nearWhite and then pops back. Does anyone know how I would animate back from nearWhite to midGray so I get a nice smooth cycle? EDIT_003: (Solution) The code suggested by dave DeLong (see below) does indeed work when modified to use the CALayer opacity style attribute: UILabel *navTitle; @property(nonatomic, retain) UILabel *navTitle; . // ADD ANIMATION CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"opacity"]; [anim setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [anim setFromValue:[NSNumber numberWithFloat:0.5]]; [anim setToValue:[NSNumber numberWithFloat:1.0]]; [anim setAutoreverses:YES]; [anim setDuration:0.5]; [[[self navTitle] layer] addAnimation:anim forKey:@"flash"]; . // REMOVE ANIMATION [[[self navTitle] layer] removeAnimationForKey:@"flash__"];

  • Does correcting a value in an validation method mark the object as dirty?

    - by dontWatchMyProfile
    From the docs: If you change the input value in a validate:error: method, you must ensure that you only change the value if it is invalid or uncoerced. The reason is that, since the object and context are now dirtied, Core Data may validate that key again later. If you keep performing a coercion in a validation method, this can therefore produce an infinite loop. So when I modify a value in a validation method, the context gets dirtied? And the next time I save, the validation happens again - and when I change the value even if the validation is OK, then the context is again dirtied, and revalidated again - and I change the value, and Core Data validates, again, because the context is dirtied. And so on...for ever... is that right? Or did they try to say something different?

  • How to store UISegmentedControle state in NSUserdefaults

    - by Chrizzz
    The problem is when de selectedSegmentIndex is unselected: "UISegmentedControlNoSegment" alias "-1". The other states (0, 1, 2 , etc.), I can store as Integers and retrieve with carTypeSegmentedControl.selectedSegmentIndex = [defaults integerForKey:@"typeOfCar"]; But -1 is no NSInteger. I also tried to remove the Integer out of the NSUserdefaults but a request would return an "0", which is not acceptable. So, is there another easy way? tnx for reading

  • How to release a "PopUp" view"?

    - by david
    I have this class that shows a popup. I do a alloc-init on it and it comes up. DarkVader* darkPopUp = [[DarkVader alloc] init:theButton helpMessage:[theButton.titleLabel.text intValue] isADay:NO offset:0]; It shows itself and if the user presses Ok it disappears. When do I release this? I could do a [self release] in the class when the OK button is pressed. Is this correct? If I do this the Analyzer says it has a retain count of +1 and gets leaked in the calling function. If I release it just after the alloc-init the Analyzer says it has a retain count of +0 and i should not release it. DLog(@"DarkVader retain count: %i", [darkPopUp retainCount]); says it has a retain count of 2. I'm confused. In short my question is: How do I release an object that gets initialized does some work and ends but no one is there to release it in the calling function.

  • Extend TTPhotoViewController with custom TTPhotoView

    - by ggould75
    I have successfully integrated the three20 framework in my project, and I have extended the TTPhotoViewController to add some further functionality. Now I need to add some subviews to the TTPhotoView loaded by the TTPhotoViewController. In particular I would like to add that subviews after every TTPhotoView as been loaded. These subviews represents sensible area over the image so they should scale proportionally with the image. The user can tap a subview to get extra info about the image. I don't know how to implement this behavior. Should I extend the TTPhotoView and make sure that the TTPhotoViewController use this extended version instead of its TTPhotoView? Could someone point me to the right direction? Thank you

  • Slider Not Behaving As I Would Expect

    - by Adam Waite
    I have a slider that changes a float from 1 to 10 but I want to save this value and use it across all view controllers so I have saved that float as an NSNumber in a model class (settingsData.sensitivitySliderSettingValue). I am trying to output the updated slider value to the console every time that it is changed however it just gets set to 0 rather than 0 to 10. I don't understand why this is... Here's my code: -(IBAction)sensitivitySliderValueChanged:(id)sender { [self updateSensitivity]; } -(void)updateSensitivity{ settingsData.sensitivitySettingValue = [NSNumber numberWithFloat:sensitivitySlider.value]; NSLog(@"The Slider Value is: %1.1f", [settingsData.sensitivitySettingValue floatValue]); }

  • UIImage Rotation

    - by Kamchatka
    I display an image in a UIImageView (within a UIScrollView) which is also stored in CoreData. In the interface, I want the user to be able to rotate the picture by 90 degrees. I also want it to be saved in CoreData. What should I rotate in the display? the scrollview, the uiimageview or the image itself? (If possible I would like the rotation to be animated) But then I also have to save the picture to CoreData. I thought about changing the image orientation but this property is readonly.

  • Getting x/y coordinate of a UITouch...

    - by Tarek
    HI, I have been trying to get the x/y coordinates from a touch on any iDevice. When getting the touch locations, everything looks ok if the touch is in the middle of the screen. But if I drag my finger to the bottom of the screen, I can only get a y coordinate of 1015. It should be getting to 1023. Same thing for dragging my finger to the top of the screen. I get -6. It should be 0. I have explicitly set the window and views to an origin of 0,0 and the width, height of the device's screen. Still nothing. I am really lost on what might be going on. Is something shifted? Am I not reading the x/y coordinates properly. Does something need to be transformed or converted? Any help would be much appreciated. T

  • Views jump during ViewDidLoad

    - by Jon-Paul
    Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

  • touchesEnded Sound?

    - by NextRev
    I'm trying to play a sound on touchesEnded but I'm having a problem. There are multiple objects that get moved around, so if the below code holds true when any object is moved, it constantly plays the sound. How do I only play it once? -(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ if(CGRectContainsRect([image1 frame], [image2 frame])){ [self playsound]; } }

  • I need a way to not rotate a subview when the parent view rotates

    - by jmurphy
    Hello, I have a situation where I have a view, and several subviews, and the view and all but one of its subviews are expected to rotate. The one subview that I don't want to rotate is a UIImageView and the image gets distorted when I rotate so I need it to simply not rotate when the rest of the views components rotate. Does anybody know of a way to achieve this? Is there some excludeFromRotating property I've overlooked? Thanks!

  • NSTimer freezes the app until it gets fired again?

    - by itai alter
    Hello all, I have a simple app with a button, UIImageView and a NSTimer. The timer is fired up every 5 seconds repeatedly to update the ImageView with a new image, while the button simply stops the timer and switches to another View. The problem is that when I press the button, nothing happens for a few seconds (until the timer fires up again). Is there a way to cause the button to stop the timer and do its job at any given time instead of between intervals of the timer? Thanks!

  • OO Objective-C design with XML parsing

    - by brainfsck
    Hi, I need to parse an XML record that represents a QuizQuestion. The "type" attribute tells the type of question. I then need to create an appropriate subclass of QuizQuestion based on the question type. The following code works ([auto]release statements omitted for clarity): QuizQuestion *question = [[QuizQuestion alloc] initWithXMLString:xml]; if( [ [question type] isEqualToString:@"multipleChoiceQuestion"] ) { [myQuestions addObject:[[MultipleChoiceQuizQuestion alloc] initWithXMLString:xml]; } //QuizQuestion.m -(id)initWithXMLString:(NSString*)xml { self.type = ...// parse "type" attribute from xml // parse the rest of the xml } //MultipleChoiceQuizQuestion.m -(id)initWithXMLString:(NSString*)xml { if( self= [super initWithXMLString:xml] ) { // multiple-choice stuff } } Of course, this means that the XML is parsed twice: once to find out the type of QuizQuestion, and once when the appropriate QuizQuestion is initialized. To prevent parsing the XML twice, I tried the following approach: // MultipleChoiceQuizQuestion.m -(id)initWithQuizRecord:(QuizQuestion*)record { self=record; // record has already parsed the "type" and other parameters // multiple-choice stuff } However, this fails due to the "self=record" assignment; whenever the MultipleChoiceQuizQuestion tries to call an instance-method, it tries to call the method on the QuizQuestion class instead. Can someone tell me the correct approach for parsing XML into the appropriate subclass when the parent class needs to be initialized to know which subclass is appropriate?
