1.其他界面是豎屏，有個界面只支持橫屏

#pragma mark 強制橫屏的方法

- (BOOL)shouldAutorotate {

returnNO;

}

- (UIInterfaceOrientationMask) supportedInterfaceOrientations {

returnUIInterfaceOrientationMaskLandscapeRight;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {

returnUIInterfaceOrientationLandscapeRight;

}

2.其他界面是豎屏，有個界面又要支持橫屏又要支持豎屏

AppDelegate.h 增加 @property(nonatomic,assign)NSInteger?allowRotation;//全局參數(shù)是否允許橫豎屏切換

初始_allowRotaion = 0

#pragma mark 設(shè)置是否可以橫豎屏切換

- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window

{

if(_allowRotation==1) {

returnUIInterfaceOrientationMaskAllButUpsideDown;//這個可以根據(jù)自己的需求設(shè)置旋轉(zhuǎn)方向

}

else

{

return(UIInterfaceOrientationMaskPortrait);

}

}

在你需要的界面viewwillAppaear設(shè)置_allowRotaion ?= 1
