If you have an IBOutlet to a UIImageView already, then all you have to do is grab an image and call setImage on the receiver (UIImageView). Two examples of grabbing an image are below. One from the Web, and one you add to your Resources folder in Xcode. UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL … Read more
You need to set the layer’s masksToBounds property to YES: cell.previewImage.layer.masksToBounds = YES; This is because the UIImageView control creates a pseudo-subview to hold the UIImage object.
Can you try setting clip to bounds [_photoview setClipsToBounds:YES]; Or directly in your Storyboard / Xib if you can :
I’ve got very simple solution! All you need is to update the center of your subview (imageview) while zooming in the ScrollViewDelegate. If zoomed image is smaller than scrollview then adjust subview.center else center is (0,0). – (void)scrollViewDidZoom:(UIScrollView *)scrollView { UIView *subView = [scrollView.subviews objectAtIndex:0]; CGFloat offsetX = MAX((scrollView.bounds.size.width – scrollView.contentSize.width) * 0.5, 0.0); CGFloat … Read more
You can see the differences between the content modes here: Redraw mode works as Scale to Fill mode. But there is a difference in how they are drawn when view geometry changes. Scale to Fill mode uses already rendered content while Redraw mode renders the content again.
It can be much simpler using the new block-based, UIKit animation methods. Suppose the following code is in the view controller, and the UIImageView you want to cross-dissolve is a subview of self.view addressable via the property self.imageView Then all you need is: UIImage * toImage = [UIImage imageNamed:@”myname.png”]; [UIView transitionWithView:self.imageView duration:5.0f options:UIViewAnimationOptionTransitionCrossDissolve animations:^{ self.imageView.image … Read more
Check that userInteractionEnabled is YES on the UIImageView. Then you can add a gesture recognizer. imageView.userInteractionEnabled = YES; UIPinchGestureRecognizer *pgr = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinch:)]; pgr.delegate = self; [imageView addGestureRecognizer:pgr]; [pgr release]; : : – (void)handlePinch:(UIPinchGestureRecognizer *)pinchGestureRecognizer { //handle pinch… }
Just pasting the solution: Just like @manohar said imageView.contentMode = UIViewContentModeCenter; if (imageView.bounds.size.width > ((UIImage*)imagesArray[i]).size.width && imageView.bounds.size.height > ((UIImage*)imagesArray[i]).size.height) { imageView.contentMode = UIViewContentModeScaleAspectFit; } solved my problem
[UIView transitionWithView:textFieldimageView duration:0.2f options:UIViewAnimationOptionTransitionCrossDissolve animations:^{ imageView.image = newImage; } completion:nil]; is another possibility
You’ll need a UITapGestureRecognizer. To set up use this: override func viewDidLoad() { super.viewDidLoad() let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:))) imageView.isUserInteractionEnabled = true imageView.addGestureRecognizer(tapGestureRecognizer) } @objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer) { let tappedImage = tapGestureRecognizer.view as! UIImageView // Your action } (You could also use a UIButton and assign an image to it, without text … Read more
