单击按钮时无法在 iPhone 中调用触摸事件
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
