单击按钮时无法在 iPhone 中调用触摸事件

Question

当我点击按钮时，我需要在 iPhone 中调用触摸事件。 我有以下代码，未调用触摸事件

请任何人告诉我如何解决此问题。

按钮代码如下。

-(无效)方法 {

BottomView = [[UIView 分配] init];

btnRefresh =[UIButton buttonWithType:UIButtonTypeCustom]; [btnRefresh setImage:[UIImage imageNamed:@"refresh_icon.png"] forState:UIControlStateNormal]; [btnRefresh setBackgroundImage:[[UIImage imageNamed:@"blue.png"]stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0] forState:UIControlStateNormal]; [btnRefresh setBackgroundImage:[[UIImage imageNamed:@"ggrey1.png"]stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0] forState:UIControlStateHighlighted]; [btnRefresh setBackgroundImage:[[UIImage imageNamed:@"ggrey1.png"]stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0] forState: UIControlStateSelected]; [btnRefresh addTarget:self 操作:@selector(KeyboardRefresh:) forControlEvents:UIControlEventTouchUpInside];
[btnRefresh setUserInteractionEnabled:YES]; [btnRefresh setMultipleTouchEnabled:YES];

[BottomView addSubview:btnRefresh];

if (self.isPortrait) {

    [btnRefresh setFrame:CGRectMake(71, 0, 40, 6)];

    [BottomView setFrame:CGRectMake(0, 160, 320, 41)];
}
else{

    [btnRefresh setFrame:CGRectMake(94, 0, 61, 8)];

    [BottomView setFrame:CGRectMake(0, 123, 480, 41)];
}

}

正在调用上述方法并且

-(void) TouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{ NSLog(@"是"); 。

当我点击刷新按钮时，没有调用

任何人都可以帮我吗？ 提前致谢

您没有 TouchBegan 的 @selector。相反，您可以将其用于 KeyboardRefresh。不要在 TouchsBegan 中检查按钮按下情况。相反，将 TouchBegan 替换为：

-(void)KeyboardRefresh:(id) sender
{ 
    NSLog(@"yes");
}
