如何从swift类调用以下目标c类别

Question

#import <UIKit/UIKit.h>

@interface UIView (AEScaningEffect)


- (void) startScaningRepeatCount:(int)count;
- (void) startScaningRepeatCount:(int)count Duration:(int)duration;
- (void) startScaningRepeatCount:(int)count Duration:(int)duration HeightFactor:(float) factor;

- (void) stopScaning;

@end

Answer 1

您可以简单地将其称为：

imgView.startScaningRepeatCount(2)

或者

imgView.startScaningRepeatCount(1000, duration: 2)

或者

imgView.startScaningRepeatCount(1000, duration: 2, heightFactor: 0.3)

等

请务必从项目的桥接标题中导入您的类别标题。

Answer 2

您可以这样称呼它：

var view = UIView(frame: CGRect.zero)

view.startScaningRepeatCount(0)
view.startScaningRepeatCount(0, duration: 0)
view.startScaningRepeatCount(0, duration: 0, heightFactor: 0)
view.stopScaning()
