问题 Let me first say that I've searched Google and, although many have similar issues, I haven't seen anything with the following bizarre behavior and remedy. I've created a UIViewController and associated nib with several IBOutlets. On trying to consume this nib from another class, I discovered that after instantiating it with initWithNibName:bundle:, the IBOutlets are still nil. I confirmed that they are correctly wired up, and yes, they are being synthesized, but still nothing. While

Initially i have to show 3 tab bar items and after sync i have to show 4th tab bar item in my app. So for this, i am hiding 4th Tab bar item using following code.

问题 I'm working on an iOS library as a Cocoa Pod. In this library, I have a custom view: @interface PlayerView : UIView @property (strong, nonatomic) IBOutlet UIView *contentView; @end @implementation PlayerView - (instancetype) initWithCoder:(NSCoder*)coder { self = [super initWithCoder:coder]; [self initialize]; return self; } - (instancetype) initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; [self initialize]; return self; } - (void)initialize { [[NSBundle mainBundle]

问题 In an attempt to convert an iPhone app to a universal app, I added a MyViewController~ipad.xib to my project. I also set the Targeted Device Family to iPhone/iPad. I then attempted to undo those changes--deleted the MyViewController~ipad.xib and set Targeted Device Family to iPhone only. Now, I can run on iPhone (as always), but not on iPad (which I could do before). I now crash with the following error: "'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed

问题 I have a UIVC loading from a Storyboard which, in turn, loads a Xib. This inner load is causing the VC to take more than a second to load. There is some fancy footwork going on in the inner xib (it loads another xib which has dynamic drawing) but this doesn't appear to be the bottleneck. According to Instruments, UIFont -initWithCoder is the culprit. (If you drill down further TBaseFont::CopyLocalizedName() is the deepest entry that accounts for the majority of the 1s time) I'm a bit stumped

问题 I write the code below: JSImgDeleteCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:displayCellID forIndexPath:indexPath]; and before use it,I registered it: [_displayImgCollectionView registerNib:[UINib nibWithNibName:displayCellID bundle:nil] forCellWithReuseIdentifier:displayCellID]; it is allright in xcode7.3, but when I run this in xcode8.1,there is sth wrong,the msg like this: invalid mode 'kCFRunLoopCommonModes' provided to CFRunLoopRunSpecific - break
