问题 As the design of table views using the grouped style changed considerably with iOS 7, I would like to hide (or remove) the first section header. So far I haven't managed to achieve it. Somewhat simplified, my code looks like this: - (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { if (section == 0) return 0.0f; return 32.0f; } - (UIView*) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if (section == 0) { UIView* view =

问题 I've been setting my own names on launch images for my apps in the Info.plist like with the following images in bundle (with correct dimensions, 320x480 px for default.png and 640x960 px for default@2x.png etc.) this have been working great prior to iOS 7 and Xcode 5.

I should also mention that this issue is not present on iOS6. 回答1: Add an empty optgroup at the end of the select list: <select> <option selected="" disabled="">Select a value</option> <option>Grumpy

问题 Until iOS7 update I was using... UIImage *image = [moviePlayer thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame]; ...with great success, so that my app could show a still of the video that the user had just taken. I understand this method, as of iOS7 has now deprecated and I need an alternative. I see there's a method of - (void)requestThumbnailImagesAtTimes:(NSArray *)playbackTimes timeOption:(MPMovieTimeOption)option though how do I return the image from it so I can

问题 Since iOS 7, a UITextView does not scroll automatically to the cursor as the user types text that flows to a new line. This issue is well documented on SO and elsewhere. For me, the issue is still present in iOS 7.1. What am I doing wrong? I installed Xcode 5.1 and targeted iOS 7.1. I'm using Auto Layout. Here's how I position the text view's content above the keyboard: - (void)keyboardUp:(NSNotification *)notification { NSDictionary *info = [notification userInfo]; CGRect keyboardRect = [
