UISplitViewControlller主控制器隐藏

Question

我正在将应用程序移植到iOS 6,我找到了一个解决方案,我已经设法触发断开视图控制器中的主视图控制器的显示,不再适用于iOS 6.

这是我用来触发iOS6上的操作的代码片段,如果设备被旋转:

- (void)hideMaster:(BOOL)hide {

[self clearOverlay];

UISplitViewController* spv = appDelegate.splitViewController;

NSLog(@"hidemaster: I do %@show the master", (hide?@"not ":@""));

self.hiddenMaster= hide;

NSLog(@"delegate=%@", spv.delegate);

[spv.view setNeedsLayout];
spv.delegate=nil;

spv.delegate=self;

}

- (BOOL)splitViewController:(UISplitViewController*)svc shouldHideViewController: (UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation {

NSLog(@"Spv: I do %@show the master", (self.hiddenMaster?@"not ":@""));

return self.hiddenMaster;
}

如何在用户旋转设备时强制触发shouldHideViewController回调？

谢谢,Fabrizio Bartolomucci

比预期更容易:我把[spv.view setNeedsLayout]; 在调用你的功能之后很快就完成了这项工作.这是为了其他用户的利益的完整代码:

- (void)hideMaster:(BOOL)hide {
   NSLog(@"hide-unhide master");
   UISplitViewController* spv = appDelegate.splitViewController;
   spv.delegate=self;
   self.hiddenMaster= hide;
   [spv willRotateToInterfaceOrientation:self.interfaceOrientation duration:0];
   [spv.view setNeedsLayout];
}

- (BOOL)splitViewController:(UISplitViewController*)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation {
   NSLog(@"Spv: I do %@ show the master", (self.hiddenMaster?@"not ":@""));
   return self.hiddenMaster;  
}
