uiimageview

问题 I have 6 images, all the same size (65x65). When I create an imageview and add this image through the "image view attributes" in the interface builder, the picture is very small. Maybe 5x5. The pictures also show up small when viewing them in the resource folder however, when running the program, they are the right size. Is there some setting I need to change to get the images to show the full size/full resolution within the interface builder? Thanks. 回答1: Make sure your UIImageView is active

问题 Greetz, So this is rather a simple question (maybe not a simple answer). I want the IB option called 'send to back' (On IB, go to Layout -> Send to back) to be done programmatically. Is it possible? If not, any suggestions to simulate the same thing? This is for an UIImageView as the title states. 回答1: Use sendSubviewToBack: [yourSubView.superview sendSubviewToBack:yourSubView]; 回答2: [self insertSubview:view atIndex:index]; Just experiment with the index you need. 来源： https://stackoverflow

问题 My code UIImage *img = [UIImage imageWithCGImage:[repr fullResolutionImage]]; [_photoPreview setImage:img]; works fine for the first time.
