UISplitViewController toggleMasterVisible 方法.方法在哪里定义? [英] UISplitViewController toggleMasterVisible method. Where is the method defined?

问题描述

我可以正确调用toggleMasterVisible"方法作为按钮操作，但我想像这样扩展方法.

I can call properly "toggleMasterVisible" method as a Button action but I want to expand the method like this.

(In Button action. It works)
.h 
@interface DetailViewController : UIViewController <UISplitViewControllerDelegate>
@end

.m
UIBarButtonItem *listBarButtonItem = [[UIBarButtonItem alloc] 
initWithImage:[UIImage imageNamed:@"list.png"] 
style:UIBarButtonItemStyleBordered 
target:self.splitViewController 
action:@selector(toggleMasterVisible:)];


(I want to expand the method)
.m
UIBarButtonItem *listBarButtonItem = [[UIBarButtonItem alloc] 
initWithImage:[UIImage imageNamed:@"list.png"] 
style:UIBarButtonItemStyleBordered 
target:self 
action:@selector(toggleMasterVisibleIfCondtionIsOK:)];

-(void)toggleMasterVisibleIfCondtionIsOK
{
     if(isConditionOK){
          [self.splitViewController toggleMasterVisible];
     }
}

但是，我收到一个错误，即‘UISplitViewController’声明没有可见的@interface".方法在哪里定义?我在参考中找不到方法(http://developer.apple.com/library/ios/#documentation/uikit/reference/UISplitViewController_class/Reference/Reference.html)以及如何调用该方法?任何帮助将不胜感激.

However, I got an error which is "No visible @interface for 'UISplitViewController' declares". Where is the method defined? I could not find the method on the reference(http://developer.apple.com/library/ios/#documentation/uikit/reference/UISplitViewController_class/Reference/Reference.html) and how can I call the method? Any help will be appreciated.

[self.splitViewController performSelector:@selector(toggleMasterVisible:)];
