在awakeFromNib中添加子视图

Question

为什么在awakeFromNib方法中添加子视图会导致它进入infinate循环？应该在哪里添加子视图？感谢。

- (void)awakeFromNib
{
     outlineViewController = [[OutlineViewController alloc] initWithNibName:nil bundle:nil];

     NSArray *subViews = [leftView subviews];
     if ([subViews count] > 0)
     {
         [[subViews objectAtIndex:0] removeFromSuperview];
     }

     [leftView addSubview:outlineViewController.view];

}

Answer 1

也许是由于

     outlineViewController = [[OutlineViewController alloc] initWithNibName:nil bundle:nil];

调用initFromCoder然后调用awakeFromNib。如果OutlineViewController是你发布的awakeFromNib的同一个对象就是这样。
