问题 If anyone experienced the issue below, please let me know if you were able to find a fix. I've spent a couple of days trying to come up with a solution, but no luck so far. I'm using XCode 4.5 with iOS 6 SDK Golden Master. Basically, my application reads and HTML file and hands its contents to a web view for rendering.

问题 I have the latest version of Xcode. In one of my projects I noticed that the views for the iPhone were the new iPhone 5 screen sizes. I like it but is there a way to switch back to the smaller screen size? Not everyone has the iPhone 5. 回答1: Also, when your building your interface, you'll see a small icon that lets you quickly switch between 4" and 3.5" screens. It's the rectangular icon on the left. It toggles back and forth between phone sizes. 回答2: There's a size property in the attributes

问题 I am building an application related to the Passbook app. Basically I am generating a boarding pass for a flight ticket and adding it to Passbook. That part is working fine. But, I want to open the Passbook app from my app to see the pass details. I have seen that Apple has removed the URL scheme options. How can I achieve this? 回答1: I had the same problem, it worked well with the emulator but crashed on the device. 1 - Double check the Entitlements 2 - I used this when the _pass is already

问题 How do I get the contents of a custom UITableViewCell to shift and resize using Auto Layout? To make the issue more clear, I've assigned the contentView of my custom cell to have a light gray background color. To reduce this to the smallest problem possible, my custom cell has only one UIImageView named ratingImageView that shows some number of yellow stars; three such cells can be seen in the image below. My ratingImageView has only 4 constraints; (1) width =81, (2) height =40, (3) align

问题 I am working with a UICollectionView that displays fewer items than necessary to fill the whole screen. With this setting, the view simply does not scroll (move and bounce), when I add like 20 items it works. How can I force the collection view to scroll, without enough items to fill the screen? (source: bytolution.com) Thanks for your help! BTW I already tried to set the contentSize (e.g. to {320 , 1000}) but it still does not work. 回答1: Try to set alwaysBounceVertical property to YES : self

问题 I have a UIButton and a UITextField ,when the button is pressed the textfield's content string will be equal to: This is a test string , how can I detect that this text field has changed its contents in this case? p.s. UITextField's delegate methods do not work in such case UPDATE: I want this behavior to be on iOS 6+ devices. 回答1: Maybe simple key-value observing will work? [textField addObserver:self forKeyPath:@"text" options:0 context:nil]; - (void)observeValueForKeyPath:(NSString *

问题 UITextAlignmentCenter seems to be deprecated in iOS 6. What are my alternatives? 回答1: For IOS 6 you should use NSTextAlignmentCenter instead of UITextAlignmentCenter : button.titleLabel.textAlignment = NSTextAlignmentCenter; Source And if you want backward compatibiliy to IOS 5 also you can do this, #ifdef __IPHONE_6_0 # define ALIGN_CENTER NSTextAlignmentCenter #else # define ALIGN_CENTER UITextAlignmentCenter #endif 回答2: #ifdef __IPHONE_6_0 # define ALIGN_CENTER NSTextAlignmentCenter #else

问题 According the docs: In iOS 6 and later, if you assign a value to this view’s restorationIdentifier property, it attempts to preserve its URL history, the scaling and scrolling positions for each page, and information about which page is currently being viewed. During restoration, the view restores these values so that the web content appears just as it did before. I'm doing all that, but nothing is happening. And even if I manually save and restore the URL the user was looking at previously,
