you can set two different images to an UIImageView, one to its image property, another to its highlightedImage property. There are many cases where you want to change the state of the image (eg: a checkmark) from off to on or vice versa. in that case, instead of you setting the UIImageView’s image to the … Read more
The reason your code doesn’t work is because the imageOrientation on the code that you have is not being taken into account. Specifically, if the imageOrientation is right/left, then you need to both rotate the image and swap width/height. Here is some code to do this: -(UIImage*)imageByScalingToSize:(CGSize)targetSize { UIImage* sourceImage = self; CGFloat targetWidth = … Read more
UIImageView has userInteractionEnabled set to NO/ false by default. You are adding the button as a subview to the image view. You should set it to YES / true.
Enable UIImage view user interaction which is disabled by default. [imageView setUserInteractionEnabled:YES]; Adding a Swipe Gesture Events UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)]; UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)]; // Setting the swipe direction. [swipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft]; [swipeRight setDirection:UISwipeGestureRecognizerDirectionRight]; // Adding the swipe gesture on image view [imageView addGestureRecognizer:swipeLeft]; [imageView addGestureRecognizer:swipeRight]; Handling Swipe Gesture … Read more
You can add tapGesture for that. Here is the code: class ViewController: UIViewController { @IBOutlet weak var imageView: UIImageView! override func viewDidLoad() { super.viewDidLoad() // create tap gesture recognizer let tapGesture = UITapGestureRecognizer(target: self, action: “imageTapped:”) // add it to the image view; imageView.addGestureRecognizer(tapGesture) // make sure imageView can be interacted with by user imageView.userInteractionEnabled … Read more
You can create graphics context and draw both images in it. You’ll get an image result from both your source images combined. – (UIImage*)imageByCombiningImage:(UIImage*)firstImage withImage:(UIImage*)secondImage { UIImage *image = nil; CGSize newImageSize = CGSizeMake(MAX(firstImage.size.width, secondImage.size.width), MAX(firstImage.size.height, secondImage.size.height)); if (UIGraphicsBeginImageContextWithOptions != NULL) { UIGraphicsBeginImageContextWithOptions(newImageSize, NO, [[UIScreen mainScreen] scale]); } else { UIGraphicsBeginImageContext(newImageSize); } [firstImage drawAtPoint:CGPointMake(roundf((newImageSize.width-firstImage.size.width)/2), roundf((newImageSize.height-firstImage.size.height)/2))]; … Read more
Example: UIImage *bgImage = [UIImage imageNamed:@”Default@2x.png”]; UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:bgImage]; backgroundImageView.frame = [[UIScreen mainScreen] bounds]; UIImage Overview: A UIImage object is a high-level way to display image data. You can create images from files, from Quartz image objects, or from raw image data you receive. The UIImage class also offers several options for … Read more
You should enable user interaction for UIImageView object: [self.storyImageView_ setUserInteractionEnabled:YES]; EDIT: Try to remove the [showStoryTapRecognizer setDelegate:self]; I don’t think UITapGestureRecognizer has its delegate methods as far as I know.
Another workaround is to add constraints to the layout Before resizing of any views. (add missing constraints e.g.). The bug only seems to occur when there are no constraints available. I have reported the bug to Apple with Bugreporter. Edit: So, at least it seems that Apple Bugreporter is working. The problem is fixed in … Read more
This seems to do the trick: UIBezierPath * imgRect = [UIBezierPath bezierPathWithRect:CGRectMake(0, 0, 100, 100)]; self.textView.textContainer.exclusionPaths = @[imgRect]; Works only from iOS 7 and up.
