uislider

问题 Got a gesture related problem. I implemented UISwipeGestureRecognizer to get swipe left and right events and that is working fine. However the problem I'm facing is that the UISlider's I have in the same view are not playing nice. The sliding motion of the sliders is being mistaken as a swipe left/right.

I have found how to change the max and min image but not the bar itself. 回答1: You were right to use -setMinimumTrackImage:forState: and -setMaximumTrackImage:forState: methods. What you missed is that you should provide stretchable UIImage to them, the

问题 I have a layout hidden from the view. On a button click I want it to slide up from the bottom pushing the entire screen contents upwards, very similar to how whatsapp shows emoticons panel in chat screen. I have seen SlidingDrawer, that dosen\'t work for me. It requires an image as an handle which is shown at the center of the screen, I don\'t want that.
