问题 I've been testing my apps under the iOS 8 Simulator in Xcode 6 GM but for some weird reason, the app interface is displaying blurry, like its been slightly zoomed. Even the status bar is zoomed in the same way. Edit: When the Launch Image loads, the zoom is correct and everything including the status bar is sharp, but then once the app loads fully, everything zooms. Has anyone else noticed this or have a fix? Thanks! 回答1: I suppose you have not added launch images for iphone 6 and iphone 6

Is there a way to programmatically get VoiceOver to say "disabled" instead of "dimmed"? 回答1: There are ways to do what you want, but you absolutely should not use them. The announcement "Dimmed" occurs, when the User Interaction Enabled trait is set to NO . This is the way VoiceOver users are use to on screen, focusable, but disabled elements being announced.

问题 Apple released a new feature allowing movie recording via QuickTime player. All you need to do is to connect the iOS 8 device to a Mac Yosemite machine, run QuickTime and set the connected device as the source of the movie. (Like explained here: http://www.tekrevue.com/tip/record-iphone-screen-quicktime/) I would like to prevent QuickTime to record a movie while my application is running. Any idea how can I do that? Any value I can change in plist? Any special event I can listen to? Any other

问题 I have header (a UICollectionReusableCell) in a UICollectionView whose height needs to be variable. How can I have it resize itself according to the height of its contents? I do not need to support iOS 7, and Autolayout solutions are preferable (if they exist). 回答1: This is how I solved it. I wish it was more elegant. Set the UILabel in the header view to have a numberOfLines value of 0. This will let it resize itself. Move the header out of the storyboard and into a xib. In collectionView(_
