我有一个导致错误的 UIView 类别,我无法确定这是该类别的 .h:
#import <UIKit/UIKit.h>
typedef NS_ENUM(NSUInteger, BCRectEdge) {
BCRectEdgeTop = 0,
BCRectEdgeLeft = 1,
BCRectEdgeBottom = 2,
BCRectEdgeRight = 3
};
@interface UIView (Genie)
/*
* After the animation has completed the view's transform will be changed to match the destination's rect, i.e.
* view's transform (and thus the frame) will change, however the bounds and center will *not* change.
*/
- (void)genieInTransitionWithDuration:(NSTimeInterval)duration
destinationRect:(CGRect)destRect
destinationEdge:(BCRectEdge)destEdge
completion:(void (^)())completion;
/*
* After the animation has completed the view's transform will be changed to CGAffineTransformIdentity.
*/
- (void)genieOutTransitionWithDuration:(NSTimeInterval)duration
startRect:(CGRect)startRect
startEdge:(BCRectEdge)startEdge
completion:(void (^)())completion;
@end
然后我将它导入视图控制器。创建一个新的 UIView 并使用其中一种方法。它在我开始输入时建议使用此方法,如果我定义它,它会出现在正确的位置。但是当我运行它时,它说:
'-[UIView genieInTransitionWithDuration:destinationRect:destinationEdge:completion:]: unrecognized selector sent to instance 0x1552c220'
有什么想法吗?快把我逼疯了。
