将从笔尖加载的子视图添加到框架中

我想在点击按钮时从笔尖文件添加视图作为我的主视图的子视图，但它必须位于框架中（0,108,320,351）。我试过下面的代码：将从笔尖加载的子视图添加到框架中

-(IBAction) displayJoinmeetup:(id)sender 
{ 
    [meetups removeFromSuperview]; //removing the older view 
    CGRect myFrame = CGRectMake(0, 108,320,351); 
    [joinmeetup initWithFrame:myFrame]; //joinmeetup declared in header file as IBoutlet UIView*joinmeetup  
    [self.view addSubview:joinmeetup];  
}

此只显示黑屏，否则如果我删除帧子视图显示覆盖了整个屏幕，我怎么能正确地做到这一点？

已创建后，您应该调用初始化...的对象上。如果您可以更改设置，则会有一个设置。在这种情况下，SETFRAME：

-(IBAction) displayJoinmeetup:(id)sender { 
    [meetups removeFromSuperview]; //removing the older view 
    CGRect myFrame = CGRectMake(0, 108,320,351); 
    [joinmeetup setFrame:myFrame]; //joinmeetup declared in header file as IBoutlet UIView*joinmeetup  
    [self.view addSubview:joinmeetup];  
}

谢谢你现在正常工作！ – sujith1406 2010-12-20 06:25:01

initWithFrame不针对从nib加载的视图调用。有关详细信息，请参阅UIView类ref。您需要在界面构建器（检查器）中设置视图大小属性。

您可以尝试THI如下：

-(IBAction) displayJoinmeetup:(id)sender 
{ 
if(meetups) 
{ 
[meetups removeFromSuperview]; //removing the older view 
//also here you should release the meetups, if it is allocated 
meetups = nil; 
} 

UIView *tempView = [[UIView alloc] initWithFrame:CGRectMake(0, 108,320,351)]; 
joinmeetup = tempView; 
[tempView release]; 
[self.view addSubview:joinmeetup]; 

}

我建议你试试这个：

[joinmeetup setFrame:CGRectMake(0, 108,320,351)]; 
[self.view addSubview:joinmeetup];

框架是在UIView中声明的属性 – 2010-12-20 06:17:09
