UIButton的自定義視圖 - addTarget：動作：forControlEvents：不工作

Question

我的按鈕如下

1. 創建LABEL1
2. 創建LABEL2
3. 創建customView（UIView）
4. 添加label1和label2自定義視圖
5. 創建myCustomButton（UIButton）
6. 在myCustomButton上添加customView

我已經爲custom_View，label1和label2做了userInteractionEnable。

然後加入

[myCustomButton addTarget:self action:@selector(OnButtonClick:) forControlEvents:UIControlEventTouchUpInside]; 

而且

-(void)OnButtonClick:(UIButton *)sender 
{ 
} 

但上述功能，甚至當我觸摸按鈕永遠不會被調用。任何解決方案

Answer 1

只是你的代碼我的朋友一個小問題，你只需要添加只有一個下面一行到你的代碼，忘了setUserInteractionEnabled:NO到UIView它可以讓你按一下按鈕

UILabel *lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 30)]; 
[lbl1 setText:@"ONe"]; 
UILabel *lbl2 = [[UILabel alloc] initWithFrame:CGRectMake(0, 30, 100, 30)]; 
[lbl2 setText:@"Two"]; 

UIView * view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 130)]; 
[view setUserInteractionEnabled:NO]; 

[view addSubview:lbl1]; 
[view addSubview:lbl2]; 

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; 
[btn addSubview:view]; 
[btn setFrame:CGRectMake(0, 0, 200, 130)]; 
[btn addTarget:self action:@selector(click) forControlEvents:UIControlEventTouchUpInside]; 

[self.view addSubview:btn]; 

單擊方法

-(void)click 
{ 
    NSLog(@"%s",__FUNCTION__); 
}

而不是創建customView（UIView的實例），您在CustomViewClicked方法

-(void)customViewClicked:(id)sender 
{ 
    UIControl *senderControl = (UICotrol *)sender; 

    NSLog(@"sender control = %@",senderControl); 
} 

成也addTarget添加customView作爲UIControl的實例的customView，

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
[button setFrame:CGRectMake(10,10,300,300)]; 

UIControl *customView = [[UIControl alloc] initWithFrame:CGRectMake(0,0,300,300)]; 
[customView addTarget:self action:@selector(customViewClicked:) forControlEvents:UIControlEventTouchUpInside]; 

UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(10,10,100,100)]; 
[label1 setText:@"Hello How are you ?"]; 

UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(10,150,100,100)]; 
[label1 setText:@"I am fine Thnank You!"] 

[customView addSubView:lebel1]; 
[customView addSubView:lebel2]; 

現在希望它能幫助你。
