uiimageview

I have a UIImageView that is animated using the following code: NSMutableArray *imageArray = [[NSMutableArray alloc] init]; for(int i = 1; i < 15; i++) { NSString *str = [NSString stringWithFormat:@"marker_%i.png", i]; UIImage *img = [UIImage imageNamed:str]; if(img != nil) { [imageArray addObject:img]; } } _imageContainer.animationImages = imageArray; _imageContainer.animationDuration = 0.5f; [_imageContainer startAnimating]; What I want now is to repeat the image to get a pattern. There is colorWithPatternImage , but that isn't made for animations. I want the whole background filled with a

well I know that every imageViews have a layer (we can access it with :imageView.layer).I would like to use the layer of my imageView and add a subLayer to it's layer: shapeLayer (that is a CAShapeLayer) My code doesn't work, it doesn't show the shape layer! - (void)viewDidLoad { imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 100, 100, 100)]; [self.view addSubview:imageView]; } - (void)anotherMethod { [imageView.layer addSublayer:shapeLayer]; } How can I solve this please ? Try this: [outputImage.layer insertSublayer:shapeLayer atIndex:0]; I solved similar problem by using

I am making application related to images. I have multiple images on my screen. I had take screen shot of that. But it should not provide my whole screen. Little part of the top most & bottom most part need not be shown in that. I have navigation bar on top. And some buttons at bottom. I don't want to capture that buttons and navigation bar in my screenshot image. Below is my code for screen shot. -(UIImage *) screenshot { UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, YES, [UIScreen mainScreen].scale); [self.view drawViewHierarchyInRect:self.view.frame afterScreenUpdates:YES];

So it looks like I have no leaks detected throughout my entire project, and I have lots of sections that do various things. However, I found that I am having some allocation issues, proven to me with mark heap in leaks instrument, which have happened most of the time when using the iPad with an external screen. The app is programmed to behave differently when connected to an external screen. I have a zoomable UIScrollView map section that I can go in and out of. When using the iPad by itself, and checking the mark heap, the heap growth will eventually go down to 0 bytes, which is good. However

I use this code to load a UIImage from a URL : NSURL *imageURL = [NSURL URLWithString:@"http://testwebsite.com/image.png"]; NSData *imageData = [[NSData alloc] initWithContentsOfURL:imageURL]; imageView.image = [UIImage imageWithData: imageData]; but I'm stuck at a URL that looks like this one : http://www.testwebsite.com/getFile?userID=123 this works fine in the browser but returns nil in the imageData variable above. how can I load the image from such an obscured URL (i.e. from a URL that does not show off the file name but rather redirects to the image file) ? thank you in advance. for some
