  • iPhone SDK: subFolders inside the main bundle

    - by codemercenary
    Hi, in the current project I have a number of folders, with subfolders, and these contain images: 01.png, 02.png. Folder1/FolderA/f1.png Folder1/FolderB/F1.png When I compile the app, I looked inside the the .app and noticed that all the images are placed in the top level, with no sub-folders. So clearly when trying to load the image this doesn't work: NSString *filePath = [[NSBundle mainBundle] pathForResource:@"f1" ofType:@"png" inDirectory:@"Folder1/FolderA"]; But even more strangely, when loading image "f1", the image actually loads "F1" UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"f1.png"]]; Anyone have ideas on how to get around this problem? Is there a compile option to create the folders in the app bundle? TIA.

  • Accessing Instance Attributes from Secondary Thread (iPhone-SDK)

    - by Travis
    I have a class with an NSDictionary attribute. Inside this class I dispatch another thread to handle NSXMLParser handling. Inside my -didStartElement, I access the dictionary in the class (to compare an element found in the XML to one in the dictionary). At this point I get undefined results. Using NSLog (I'm not advanced in XCode debugging), I see that it bombs around access of the NSDictionary. I tried just iterating the dictionary and dumping the key/values inside the didStartElement and this bombs at different keys each time. The only thing I can conclude is that something is not kosher that I'm doing with regards to accessing main thread attributes from the secondary thread. I'm somewhat new to multithreading and am not sure what the best protocol is safely access attributes from additional threads. Thanks all.

  • iPhone SDK 3.2 UIGestureRecognizer interfering with UIView animations?

    - by Brian Cooley
    Are there known issues with gesture recognizers and the UIView class methods for animation? I am having problems with a sequence of animations on a UIImageView from UIGestureRecognizer callback. If the sequence of animations is started from a standard callback like TouchUpInside, the animation works fine. If it is started via the UILongPressGestureRecognizer, then the first animation jumps to the end and the second animation immediately begins. Here's a sample that illustrates my problem. In the .xib for the project, I have a UIImageView that is connected to the viewToMove IBOutlet. I also have a UIButton connected to the startButton IBOutlet, and I have connected its TouchUpInside action to the startButtonClicked IBAction. The TouchUpInside action works as I want it to, but the longPressGestureRecognizer skips to the end of the first animation after about half a second. When I NSLog the second animation (animateTo200) I can see that it is called twice when a long press starts the animation but only once when the button's TouchUpInside action starts the animation. - (void)viewDidLoad { [super viewDidLoad]; UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(startButtonClicked)]; NSArray *recognizerArray = [[NSArray alloc] initWithObjects:longPressRecognizer, nil]; [startButton setGestureRecognizers:recognizerArray]; [longPressRecognizer release]; [recognizerArray release]; } -(IBAction)startButtonClicked { if (viewToMove.center.x < 150) { [self animateTo200:@"Right to left" finished:nil context:nil]; } else { [self animateTo100:@"Right to left" finished:nil context:nil]; } } -(void)animateTo100:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:@"Right to left" context:nil]; [UIView setAnimationDuration:4]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animateTo200:finished:context:)]; viewToMove.center = CGPointMake(100.0, 100.0); [UIView commitAnimations]; } -(void)animateTo200:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:@"Left to right" context:nil]; [UIView setAnimationDuration:4]; viewToMove.center = CGPointMake(200.0, 200.0); [UIView commitAnimations]; }

  • iPhone SDK NSString To NSDate

    - by disp
    I got a string from parsing a XML file which looks like this: Fri, 09 Apr 2010 00:00:45 +0200 and the corresponding pattern should be this "EEE, dd MMM yyyy HH:mm:ss ZZ", but I get (null). This is my code: NSString *dateString = @"Fri, 09 Apr 2010 00:00:45 +0200"; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ss ZZ"]; NSDate *date = [dateFormatter dateFromString:dateString]; NSLog(@"date:%@",date); // result date:(null) Edit: This works for me now, I had to switch to en-US locale: NSLocale* usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en-US"]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setLocale:usLocale]; [dateFormatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ss ZZ"]; NSDate *date = [dateFormatter dateFromString:dateString];

  • image filters for iphone sdk development

    - by plsp
    Hi All, I am planning to develop an iphone app which makes use of image filters like blurring, sharpening,etc. I noticed that there are few approaches for this one, Use openGL ES. I even found an example code on apple iphone dev site. How easy is openGL for somebody who has never used it? Can the image filters be implemented using the openGL framework? There is a Quartz demo as well posted on apple iphone dev site. Has anybody used this framework for doing image processing? How is this approach compared to openGL framework? Don't use openGL and Quartz framework. Basically access the raw pixels from the image and do the manipulation myself. Make use of any custom built image processing libraries like this one. Do you know of any other libraries like this one? Can anybody provide insights/suggestions on which option is the best? Your opinions are highly appreciated. Thanks!

  • iPhone SDK: Get GPS coordinates from Google Maps

    - by RaYell
    In an iPhone application I'm developing I need to get GPS coordinates to perform some actions based on the values received. Users should have two possibilities of giving the location: automatically from iPhone build-in GPS by finding a specific point on a map (Google Maps) I know how to user CLLocationManager to get current position coordinates and I know how to add Google Maps using JS API. What I would like to know if how can I get coordinates for a specific point on a map that user clicks. Is that possible with UIWebView or is there any other way of getting the values I need?

  • New to iPhone SDK: touchesBegan not called

    - by coriolan
    Hi, I created a very very basic iPhone app with File/New Projet/View-Based application. No NIB file there. Here is my appDelegate .h @interface MyAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MyViewController *viewController; } .m - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } And here is my loadView method in my controller - (void)loadView { CGRect mainFrame = [[UIScreen mainScreen] applicationFrame]; UIView *contentView = [[UIView alloc] initWithFrame:mainFrame]; contentView.backgroundColor = [UIColor redColor]; self.view = contentView; [contentView release]; } Now, in order to catch the touchesBegan event, I created a new subclass of UIView: .h @interface TouchView : UIView { } .m - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"Touch detected"); } and modified the second line in my loadView into this : TouchView *contentView = [[UIView alloc] initWithFrame:mainFrame]; Why is touchesBegan never called?

  • Can't change background for UIWebView in iPhone SDK

    - by leon
    Hi, Is there a way to change background color for UIWebView? None of the colors set in IB effect UIWebView behavior: before acctual content is loaded it shows as up as white (causing a white flash between the moment it is loaded and content is rendered). Setting background color programmatically does not do anything either. Here is code: @interface Web_ViewViewController : UIViewController { UIWebView *web; } @property (nonatomic, retain) IBOutlet UIWebView *web; @end .... (void)viewDidLoad { super viewDidLoad; web.backgroundColor = UIColor blueColor; NSURL *clUrl = NSURL URLWithString:@"http://www.apple.com" ; NSURLRequest *req = NSURLRequest requestWithURL:clUrl; web loadRequest:req; } thanks

  • iPhone SDK / Facebook Connect: Using a custom login dialog

    - by boliva
    Exactly what the title says. Is it possible to use Facebook Connect (or any other means of FB integration) in a native iPhone app without resorting to the built in login dialog (which looks awful)? Something where I could create my own custom login screen asking for the facebook login username and password and then using the fbconnect native methods to validate that info and retrieve a valid session?

    Looking at the QuartzDemo sample application, I love the speed of the PDF rending using quartz alone (that is, without using uiwebview). However, when I'm zooming in the PDF it doesn't seem to become more clear like it does in PDF view. Is there something that I can change to have the same effect when zooming in and out using multitouch? like manipulate the PDF transformation matrix or something? Thanks a bunch. --Ben

  • iPhone SDK: Rendering a CGLayer into an image object

    - by codemercenary
    Hi all, I am trying to add a curved border around an image downloaded and to be displayed in a UITableViewCell. In the large view (ie one image on the screen) I have the following: productImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:product.image]]; [productImageView setAlpha:0.4]; productImageView.frame = CGRectMake(10.0, 30.0, 128.0, 128.0); CALayer *roundedlayer = [productImageView layer]; [roundedlayer setMasksToBounds:YES]; [roundedlayer setCornerRadius:7.0]; [roundedlayer setBorderWidth:2.0]; [roundedlayer setBorderColor:[[UIColor darkGrayColor] CGColor]]; [self addSubview:productImageView]; In the table view cell, to get it to scroll fast, an image needs to be drawn in the drawRect method of a UIView which is then added to a custom cell. so in drawRect - (void)drawRect:(CGRect)rect { ... point = CGPointMake(boundsX + LEFT_COLUMN_OFFSET, UPPER_ROW_TOP); //CALayer *roundedlayer = [productImageView layer]; //[roundedlayer setMasksToBounds:YES]; //[roundedlayer setCornerRadius:7.0]; //[roundedlayer setBorderWidth:2.0]; //[roundedlayer setBorderColor:[[UIColor darkGrayColor] CGColor]]; //[productImageView drawRect:CGRectMake(boundsX + LEFT_COLUMN_OFFSET, UPPER_ROW_TOP, IMAGE_WIDTH, IMAGE_HEIGHT)]; // [productImageView.image drawInRect:CGRectMake(boundsX + LEFT_COLUMN_OFFSET, UPPER_ROW_TOP, IMAGE_WIDTH, IMAGE_HEIGHT)]; So this works well, but if I remove the comment and try to show the rounded CA layer the scrolling goes really slow. To fix this I suppose I would have to render this image context into a different image object, and store this in an array, then set this image as something like: productImageView.image = (UIImage*)[imageArray objectAtIndex:indexPath.row]; My question is "How do I render this layer into an image?" TIA.
