关于解决MGSPlitview iOS版本兼容性问题

问题：运行在4.3模拟器上的程序，到5.01失败了，错误信息如下

MGSplitView[839:f803] *** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<RootViewController: 0x6886380> should have parent view controller:<MGSplitViewController: 0x6ca1c00> but actual parent is:<UINavigationController: 0x6886980>'

解决方案：

UINavigationController *test=[[UINavigationController alloc] initWithRootViewController:detailViewController];
    test.navigationBar.hidden=YES;
    [test retain];
	//invokes a method of the receiver on the current thread using the default mode after a delay.
	[rootViewController performSelector:@selector(selectFirstRow) withObject:nil afterDelay:0];
	[detailViewController performSelector:@selector(configureView) withObject:nil afterDelay:0];
    
 self.splitViewController.viewControllers=[[NSArray alloc] initWithObjects:
rootViewController
,test, nil];

代码修改：

 UINavigationController *root=[[UINavigationController alloc] initWithRootViewController:rootViewController]
 UINavigationController *test=[[UINavigationController alloc] initWithRootViewController:detailViewController];
    test.navigationBar.hidden=YES;
    [test retain];
	//invokes a method of the receiver on the current thread using the default mode after a delay.
	[rootViewController performSelector:@selector(selectFirstRow) withObject:nil afterDelay:0];
	[detailViewController performSelector:@selector(configureView) withObject:nil afterDelay:0];
    
    self.splitViewController.viewControllers=[[NSArray alloc] initWithObjects:root,test, nil];

看完下图就明白为什么这么修改了：

NavigationController的rootviewController 对应了class:rootviewController //

在nib中的 结构，和用代码修改后的view controller结构不一样了，因此在ios 5的情况下，检查严格了，就出错了：

也有一些提出的解决此类问题的方法：

self.view=xxxxxcontroller.view

替换为：self.view addsubview:xxxcontroller.view
