我正在使用此IBAction加载两个不同的视图- (IBAction)showFirstView:(id)sender{ theDetailViewController = [DetailViewController new]; [theDetailViewController initWithNibName:@"DetailView" bundle:nil]; NSView *splitRightView = [[theSplitView subviews] objectAtIndex:1]; NSView *aDetailView = [theDetailViewController view]; [aDetailView setFrame:[splitRightView bounds]]; [aDetailView setAutoresizingMask:(NSViewWidthSizable | NSViewHeightSizable)]; [splitRightView addSubview:aDetailView]; NSLog(@"%@",(NSString *)splitRightView);}- (IBAction)showSecondView:(id)sender{ theNewViewController = [NewViewController new]; [theNewViewController initWithNibName:@"NewView" bundle:nil]; NSView *splitRightView = [[theSplitView subviews] objectAtIndex:1]; NSView *aDetailView = [theNewViewController view]; [aDetailView setFrame:[splitRightView bounds]]; [aDetailView setAutoresizingMask:(NSViewWidthSizable | NSViewHeightSizable)]; [splitRightView addSubview:aDetailView]; NSLog(@"%@",(NSString *)splitRightView);}
但有了这段代码，我只是将子视图放在彼此前面的堆栈中
添加新的子视图之前，如何从splitRightView中删除子视图？
谢谢。
最佳答案
尝试以下操作（假设您要删除第一个子视图）：
[[[splitRightView subviews] objectAtIndex:0] removeFromSuperview];
