//支援Xcode 4.5 - (NSUInteger) supportedInterfaceOrientations{ //僅正面 // return UIInterfaceOrientationMaskPortrait; //支援縱向 （利用 | 設定多參數） // return UIInterfaceOrientationMaskPortrait // | UIInterfaceOrientationMaskPortraitUpsideDown; //支援橫向 //UIInterfaceOrientationMaskLandscape: 支援按鈕在左、按鈕在右 // return UIInterfaceOrientationMaskLandscape; //支援四個方向 return UIInterfaceOrientationMaskAll; } - (BOOL) shouldAutorotate { return YES; } |
TabBarController設定方式
假使今天要控制所有畫面中，某些可支援旋轉，某些不行，
在有使用Navigation Controller和TabBarController的狀況時，
則需要這樣設定：
- 勾選支援畫面旋轉
- 在AppDelegate加上這段程式碼
12345678910- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{NSUInteger orientations = UIInterfaceOrientationMaskAll;if (self.window.rootViewController) {UIViewController* presented = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];orientations = [presented supportedInterfaceOrientations];}return orientations;} - 在tabBarController裡加上
1234567891011121314-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];}-(NSUInteger)supportedInterfaceOrientations{if (self.selectedViewController)return [self.selectedViewController supportedInterfaceOrientations];return UIInterfaceOrientationMaskPortrait;}-(BOOL)shouldAutorotate{return [self.selectedViewController shouldAutorotate];} - 不支援旋轉的子畫面加上
1234567891011121314- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{return (interfaceOrientation == UIInterfaceOrientationPortrait);}- (BOOL)shouldAutorotate{return NO;}- (NSUInteger)supportedInterfaceOrientations{return UIInterfaceOrientationMaskPortrait;} - 要支援旋轉的子畫面加上
1234567891011121314- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{return YES;}- (BOOL)shouldAutorotate{return YES;}- (NSInteger)supportedInterfaceOrientations{return UIInterfaceOrientationMaskAllButUpsideDown;}
Navigation Controller設定方式
若要控制在Navigation Controller之下的單獨畫面是否支援旋轉，則需要在Controller裡加上這段
|
1 2 3 4 5 6 7 8 9 10 11 12 |
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return [self.visibleViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } - (BOOL)shouldAutorotate { return [self.visibleViewController shouldAutorotate]; } - (NSUInteger)supportedInterfaceOrientations { return [self.visibleViewController supportedInterfaceOrientations]; } |
