iphone - 将 @selector 传递给我的 UIbutton 但单击事件没有响应

Question

我的代码:

 - (void)showWithStatus:(NSString *)status barColor:(UIColor*)barColor textColor:(UIColor*)textColor click:(SEL)click{
    if(!self.superview)
        [self.overlayWindow addSubview:self];
    [self.overlayWindow setHidden:NO];
    [self.topBar setHidden:NO];
    self.topBar.backgroundColor = barColor;
    NSString *labelText = status;
    CGRect labelRect = CGRectZero;
    CGFloat stringWidth = 0;
    CGFloat stringHeight = 0;
    if(labelText) {
        CGSize stringSize = [labelText sizeWithFont:self.stringLabel.font constrainedToSize:CGSizeMake(self.topBar.frame.size.width, self.topBar.frame.size.height)];
        stringWidth = stringSize.width;
        stringHeight = stringSize.height;

        labelRect = CGRectMake((self.topBar.frame.size.width / 2) - (stringWidth / 2), 0, stringWidth, stringHeight);
    }
    self.stringLabel.frame = labelRect;
    self.stringLabel.alpha = 0.0;
    self.stringLabel.hidden = NO;
    self.stringLabel.text = labelText;
    self.stringLabel.textColor = textColor;

    clickBn=[[UIButton alloc]initWithFrame:self.stringLabel.frame];
    clickBn.backgroundColor=[UIColor blueColor];
    [clickBn addTarget:self action:click forControlEvents:UIControlEventTouchUpInside];

    if(!clickBn.superview)
        [self.topBar addSubview:clickBn];


    [UIView animateWithDuration:0.4 animations:^{
        self.stringLabel.alpha = 1.0;
    }];
//    [self setNeedsDisplay];
}

并调用此方法:

 - (IBAction)successButtonPressed:(id)sender {
[KGStatusBar showSuccessWithStatus:@"Successfully synced" click:@selector(clickBn)];
 }


 - (void)clickBn {
NSLog(@"sss");
 [KGStatusBar dismiss];
}

NSLog(@"sss") 不显示。我想将一个方法传递给customView的UIButton，但是当我单击UIbutton时没有响应。

在 @interface 之前和头文件之后的 .h 文件中创建控件委托(delegate)。

@protocol YourControlDelegate <NSObject>

-(void) delegateMethod;

@end

在@interface

@property (nonatomic,assign) id <YourControlDelegate> yourdelegate;

在.m @synthesize中的yourdelegate。

在按钮点击操作中调用[self.yourdelegate delegateMethod];

在您的ViewController中添加YourControlDelegate，如下所示

@interface YourVC : UIViewController <YourControlDelegate>

在.m中实现delegate方法

-(void) delegateMethod
{
    //you code.
}

这里，当您单击按钮时，viewController 中的 delegateMethod 将被调用。
