In practical terms, don’t do that. Instead add a button with Custom style (no button graphics unless you specify images) over the UIImageView. Then attach whatever methods you want called to that. You can use that technique for many cases where you really want some area of the screen to act as a button instead … Read more
SWIFT 5 let preArrowImage : UIImageView // also give it frame let singleTap = UITapGestureRecognizer(target: self, action: #selector(tapDetected)) preArrowImage.isUserInteractionEnabled = true preArrowImage.addGestureRecognizer(singleTap) //Action func tapDetected() { print(“Imageview Clicked”) } Objective-c UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapDetected)]; singleTap.numberOfTapsRequired = 1; [preArrowImage setUserInteractionEnabled:YES]; [preArrowImage addGestureRecognizer:singleTap]; -(void)tapDetected{ NSLog(@”single Tap on imageview”); }
It’s not necessary to rewrite everything. I recommend doing this instead: Post this inside your .m file of your custom cell. – (void)layoutSubviews { [super layoutSubviews]; self.imageView.frame = CGRectMake(0,0,32,32); } This should do the trick nicely. :]
tldr: ImagedNamed is fine. It handles memory well. Use it and stop worrying. Edit Nov 2012: Note that this question dates from iOS 2.0! Image requirements and handling have moved on a lot since then. Retina makes images bigger and loading them slightly more complex. With the built in support for iPad and retina images, … Read more
It’s all good, man. Don’t harm yourself or others. You probably don’t want to store these images in Core Data, since that can impact performance if the data set grows too large. Better to write the images to files. NSData *pngData = UIImagePNGRepresentation(image); This pulls out PNG data of the image you’ve captured. From here, … Read more
First you create a UIImage from your image file, then create a UIImageView from that: let imageName = “yourImage.png” let image = UIImage(named: imageName) let imageView = UIImageView(image: image!) Finally you’ll need to give imageView a frame and add it your view for it to be visible: imageView.frame = CGRect(x: 0, y: 0, width: 100, … Read more
Have you tried [myColor isEqual:someOtherColor] ?
With OS > 3.0 you can do this: //you need this import #import <QuartzCore/QuartzCore.h> [imageView.layer setBorderColor: [[UIColor blackColor] CGColor]]; [imageView.layer setBorderWidth: 2.0];
Instead of this code: [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate]; you should have: image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate]; Use this in Swift 4.1 image = UIImage(named: “name”)!.withRenderingMode(.alwaysTemplate)
