问题 I have an ImageZoom class that subclasses UIView and is a delgate for the UIScrollView. It's pretty straight forward. The class contains a UIScrollView which contains a UIImageView. When an instance of the class is added to a view controller the image is zoomed so that it is flush with the view. There is a method that zooms in when you double tap and zooms out when repeated. Everything works great except for when I change orientation to landscape. I can't seem to figure out how to get the

I have the following code: - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex]; if ([buttonTitle isEqualToString:@"Text"]) { AddTextViewController *addTextViewController =

问题 If I have an "old" app with a NavBar and build it with iOS7, the StatusBar is visible together with the NavBar and it looks like a mess! And if I have a flip view (TransitionStyleFlipHorizontal), that TopBar is placed below the StatusBar and when turning back the view the window jumps up in an ugly way to cover the StausBar again. Do I have to reconstruct everything from scratch to make it look good. Just to make the StausBar stay on top of the NavBar? It must a simple way to fix that but how

问题 My UIPageViewController was working fine in iOS 5. But when iOS 6 came along, I wanted to use the new scroll transition style (UIPageViewControllerTransitionStyleScroll) instead of the page curl style. This caused my UIPageViewController to break. It works fine except right after I've called setViewControllers:direction:animated:completion: . After that, the next time the user scrolls manually by one page, we get the wrong page. What's wrong here? 回答1: My workaround of this bug was to create

问题 I have a very strange problem that I don't understand. I have a UITableView which causes a crash when I click on a row. self.tableView.backgroundColor = [UIColor clearColor]; self.tableView.delegate = self; <-- If I remove this, no crash caused self.tableView.dataSource = self; The funny thing is that I have no code at all inside didSelectRowAtIndexPath , and is still crashes?
