Iphone 如何使用带有参数的UIButton释放/的父UIView？

我想知道是否有一种方法可以释放UIView，它不存在于通过子视图UIButton的特定函数之外。因为我无法通过iAction的按钮给出指向UIView的指针参数，所以我被卡住了

- (IBAction)statsTemp1:(id)sender{


CGRect newSize = CGRectMake(0,13,322,434);
 UIView *overl = [[UIView alloc] initWithFrame:newSize];
 [self.view addSubview:overl];
 [overl setBackgroundColor:[UIColor grayColor]];
 [overl setAlpha:0.85];
 [self doTheGraphIn:overl];
 CGRect btnFrame = CGRectMake(150, 400, 30, 30);
 UIButton *closeStatButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
 closeStatButton.frame = btnFrame;
 [overl addSubview:closeStatButton];
 [closeStatButton addTarget:self action:@selector(closeStat:) forControlEvents:UIControlEventTouchUpInside];}-(IBAction)closeStat:(id)sender{
 [self release];
    }
    -(IBAction)closeStat:(id)sender{
 [overl release];
    }

我只想对claryfy说：我想用按钮释放UIView*overl，但不能事先创建它

谢谢您的帮助，我很感激：

听起来您想从self.view中删除over1。这意味着释放

试试这个…从记忆中，所以请检查

- (IBAction)statsTemp1:(id)sender{

// Create UIView
     CGRect newSize = CGRectMake(0,13,322,434);
     UIView *overl = [[UIView alloc] initWithFrame:newSize];
     [overl setBackgroundColor:[UIColor grayColor]];
     [overl setAlpha:0.85];
     [over1 setTag:99];

// Add UIButton to overl
       CGRect btnFrame = CGRectMake(150, 400, 30, 30);
       UIButton *closeStatButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
       closeStatButton.frame = btnFrame;
       [overl addSubview:closeStatButton];
       [closeStatButton addTarget:self action:@selector(closeStat:)   forControlEvents:UIControlEventTouchUpInside];

// Add overl to view
     [self.view addSubview:overl];

// over1 can now be released because self.view has a pointer to it
       [overl release];

// Do God knows what
     [self doTheGraphIn:overl];

 }

// Remove overl from self.view
-(IBAction)closeStat:(id)sender {
     UIView *overl = [self.view viewForTag:99];
     [over1 removeFromSuperView];
  }

// The UIButton is autorelease, so you should be good.

这就成功了。非常感谢你！永远不会想到UIView*overl=[self.view viewWithTag:99]；[上覆从SuperView移除]；
