Question

实际上，我必须在点击按钮后显示和消失视图。请告诉我完成任务的具体代码

happyView=[[UIView alloc]init];
happyView.frame=CGRectMake(MainView.frame.size.width*0.26,CGRectGetHeight(happyBtn.frame)*2.2, CGRectGetWidth(MainView.frame)/1.6, CGRectGetHeight(MainView.frame)/3);
happyView.layer.cornerRadius=8.0;
happyView.layer.borderWidth=0.5;
happyView.layer.borderColor=[[UIColor grayColor]CGColor];
[MainView addSubview:happyView];    

LettingGo=[[UIButton alloc]init];
LettingGo.frame=CGRectMake(happyView.frame.size.width*0.01,happyView.frame.size.height*0.1, CGRectGetWidth(happyView.frame)/1.05, 50);
[LettingGo setTitle:@"Letting go of negativity" forState:UIControlStateNormal];
LettingGo.titleLabel.numberOfLines=2;
LettingGo.titleLabel.adjustsFontSizeToFitWidth=YES;
[LettingGo setBackgroundColor:[UIColor colorWithRed:0.400f green:0.737f blue:0.761f alpha:1.00f]];
[happyView addSubview:LettingGo];

LivingPresent=[[UIButton alloc]init];
LivingPresent.frame=CGRectMake(happyView.frame.size.width*0.01,LettingGo.frame.size.height*1.4, CGRectGetWidth(happyView.frame)/1.05, 40);
[LivingPresent setTitle:@"Living in the present" forState:UIControlStateNormal];
LivingPresent.titleLabel.adjustsFontSizeToFitWidth=YES;
[LivingPresent setBackgroundColor:[UIColor colorWithRed:0.400f green:0.737f blue:0.761f alpha:1.00f]];
[happyView addSubview:LivingPresent];
happyView.hidden=YES;

...

- (void)tapHappy:(id)selector {
    happyView.hidden=NO;
}

Answer 1

UIButton有一个方法addTarget，可以在按钮上发生操作时调用方法

[yourButton addTarget:self action:@selector(tapHappy:) forControlEvents:UIControlEventTouchUpInside];

当用户从“UIControlEventTouchUpInside”按钮上抬起手指时，这将搜索“self”中的类以获取方法“tapHappy：”

显然，您可以根据需要更改这些值

但那应该是你想要的......我想..

然后可能更改tapHappy方法，因此它不会总是将YES设置为隐藏属性...可能类似

happyView.hidden=!happyView.hidden;

这将打开和关闭

Answer 2

当您致电tapHappy方法检查天气时，您的happyView是否隐藏。

UIButton * yourButton=[[UIButton alloc]init];
    yourButton.frame=CGRectMake(YOUR_FRAME);
    [yourButton setTitle:@"Title" forState:UIControlStateNormal];
    [yourButton addTarget:self action:@selector(tapHappy:) forControlEvents:UIControlEventTouchUpInside];
    [yourButton setBackgroundColor:[UIColor colorWithRed:0.400f green:0.737f blue:0.761f alpha:1.00f]];
    [YourView addSubview:yourButton];




-(void)tapHappy:(id)selector{
    if(happyView.hidden)
        happyView.hidden = NO;
    else
        happyView.hidden = YES;
}
