问题 This problem comes when I build an app targeting iOS 5 or 6, but run it on iOS 7. If I have a controller in a navigationController that is a part of a tabBarController, and I do the following: controller.hidesBottomBarWhenPushed = YES; [self.navigationController pushViewController:testController animated:YES]; A strange vertical positioning animation occurs. I would instead like the new controller (with the bottom bar hidden) to push or pop on the navigation controller pushing the tab bar out

问题 Now that we have iOS 7, Apple apparently has removed the option to receive keyboard notifications from -sendEvent: . This is a huge pain to people who are wanting to write something that captures all key events and sends it off to a remote computer, E.G. a VNC client. UIKeyCommand does not provide the functionality needed. There are many bug reports submitted to apple, but they will not listen. The bug report apple is closing all reports as a duplicate is rdar://14129420. What is the best

问题 There's a pretty big bug in Safari 7 on both Mac and iOS that's hard to find anything on, but is pretty easy to fix. In some situations when using position:fixed, Safari 7 fails to draw part of the page when scrolling. This can be seen at http://ruelculture.com/glitchy.html by clicking on the arrow, waiting a bit and trying to scroll back up. 回答1: To fix this, force hardware acceleration on the disappearing element by adding the following CSS hack: -webkit-transform: translate3d(0, 0, 0); See

问题 It is a simple pull to refresh case. I have data loaded into table and have a mutable data array at back-end, I receive a array of new data and want to add this complete array at start of existing array. One workaround is to create new array with new arrived data and then add previous array into it using addObjectsFromArray: method. Is there some workaround to add new data array to the start of previous array directly? 回答1: First, build an NSIndexSet . NSIndexSet *indexes = [NSIndexSet

问题 Just wondering if this is possible. Currently, the first time I play a sound file while the app is running, there is a noticeable delay before the sound actually plays (like it's caching it or something). After this it plays instantly without issue, but if I close the app completely and relaunch it, the delay will be back the first time the sound is played. Here is the code I'm using to play the sound: [self runAction:[SKAction playSoundFileNamed:@"mySound.caf" waitForCompletion:NO]]; 回答1:

问题 In iOS 7.0, I hid the status bar in my apps by adding <key>UIStatusBarHidden</key> <true/> <key>UIViewControllerBasedStatusBarAppearance</key> <false/> to the info.plist. I just updated my testing iPad to iOS 7.1, and the status bar is now back in all of my apps. How can I hide it in both 7.0 and 7.1? Update: This is only happening in iPhone apps running on the iPad, I don't see this problem on the iPhone or in the simulator. 回答1: In the view controllers in which you want the status bar

问题 The question is what's the right-most way to display a separator in the last cell in a table/section. Basically this is what I am after. This is from the native music app, which makes me think that it should be possible to achieve just by means of UITableView , they would not be using some private API for cell separators, right? I know you can get away without using actual separators, but adding one pixel line in the bottom of the cell. But I'm not a fan of this approach because When a cell
