1叁征、屏蔽AppDelegate下面的屏幕旋轉(zhuǎn)方法
#pragma mark - 屏幕旋轉(zhuǎn)的
//-(UIInterfaceOrientationMask)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window {
// return UIInterfaceOrientationMaskPortrait;
//}````
2家破、對(duì)UINavigationController和UITabBarController寫兩個(gè)擴(kuò)展類別屹篓，此東西不需要在具體的ViewController中引用
UINavigationController+Autorotate.h

}

{
return [self.topViewController supportedInterfaceOrientations];
}

{
return [self.topViewController preferredInterfaceOrientationForPresentation];
}
@end````

3.在使用的ViewController中的再次重寫這三個(gè)方法，可以在根ViewController中重寫如下方法混巧，就能實(shí)現(xiàn)豎屏细睡，子ViewController再重寫實(shí)現(xiàn)旋轉(zhuǎn)
- (BOOL)shouldAutorotate {
//是否允許轉(zhuǎn)屏
return NO;
} - (UIInterfaceOrientationMask)supportedInterfaceOrientations{
//viewController所支持的全部旋轉(zhuǎn)方向
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
} - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{ //viewController初始顯示的方向
return UIInterfaceOrientationPortrait;
}
注意：在使用的時(shí)候發(fā)現(xiàn)在ios9以下的版本出現(xiàn)一個(gè)奇怪的問題，就是編譯出來的app默認(rèn)是橫的忍宋，解決辦法是看app.plist下面Supported interface orientations里的列表中痕貌，正屏的是不是排在第一個(gè)。
