rotation - UISplitViewController主 Controller 隐藏

Question

我正在将一个应用程序移植到 iOS 6，并且发现了一个用于触发和关闭分割 View Controller 中主视图 Controller 显示的解决方案，该解决方案不再适用于 iOS 6。

这是我用来触发 iOS6 上的操作的代码，如果设备旋转，该操作就会起作用:

- (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;
}

如何在用户不旋转设备的情况下强制触发 shouldHideViewController 回调？

谢谢，法布里齐奥·巴尔托洛穆奇

比预期容易:我把 [spv.view setNeedsLayout];调用您的函数后不久，它就完美地完成了工作。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;  
}
