Is there exist a way to use assets in storyboard from different bundle? Thanks. 回答1: So, based on answers to this question, I do know of one solution. Sounds like you've already done some of

问题 I have a very basic screen sharing iPhone app, I have successfully added the pinch/zoom effect to my app using a UIImageView inside a UIScrollView . The UIImageView receives the screen content from the PC on a regular interval. Everything works fine but as soon as I scroll/pinch/zoom it works at first but then it stops, and the delegate method that's updating the image view content stops firing up even though the server still sends the screen content. The whole app seems to be frozen but

问题 In my UICollectionViewCell class I wrote this: - (void)layoutSubviews { [super layoutSubviews]; self.myImageView.layer.cornerRadius = CGRectGetHeight(self.myImageView.frame) / 2; self.myImageView.layer.masksToBounds = YES; } But this does not work correctly in all cases, it appears like this: 回答1: I faced a similar problem trying to get a collectionView inside a TableView Cell.

问题 i've got an UIImageView, now i want to repeat this image, that it always shows up again when scrolling left or right. Little Example: is this possible? it should feel like an infinite loop 回答1: The word "infinite" rules out a UISCrollView or a CATiledLayer , obviously. I'd say the easiest way to achieve this is to initialize enough UIImageView s to completely fill your screen (or scroll area), plus one, and implement your own dragging/scrolling system and recycle the UIImageView s as they go

问题 I'm currently trying to create a subclass of UIImageView in order to make it download its image from server asynchronously ;) I tried to do it by myself but I haven't gone very far yet :D Anyway, I looked around here and found this : AsyncImageDownload I had a look at the code and the first which springs to mind is : why subclassing a UIView and not a UIImageView ?!?
