[英]Is it possible to prevent iPhone/iPad orientation changing in the browser?
[英]iOS (iPhone/iPad) SDK - Application not changing orientation
在我的自定義標簽欄應用程序中,即使強制旋轉狀態欄,方向也似乎從未改變。 這是我在AppDelegate中的代碼:
AppDelegate.h:
#import <UIKit/UIKit.h>
#import "MBProgressHUD.h"
@class exampleViewContoller;
@class example1ViewController;
@class example2ViewController;
@class example3ViewController;
@class example4ViewController;
@interface <appname>AppDelegate : NSObject <UIApplicationDelegate, MBProgressHUDDelegate> {
UIWindow *window;
UITabBarController *rootController;
exampleViewContoller *viewController;
example1ViewController *viewController1;
example2ViewController *viewController2;
example3ViewController *viewController3;
example4ViewController *viewController4;
NSMutableData *responseData;
NSMutableArray *tweets;
MBProgressHUD *HUD;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *rootController;
@property (nonatomic, retain) IBOutlet exampleViewContoller *viewController;
@property (nonatomic, retain) IBOutlet example1ViewController *viewController1;
@property (nonatomic, retain) IBOutlet example2ViewController *viewController2;
@property (nonatomic, retain) IBOutlet example3ViewController *viewController3;
@property (nonatomic, retain) IBOutlet example4ViewController *viewController4;
@property (nonatomic, retain) NSMutableArray *tweets;
@end

問題是,當我在iOS Simulator中旋轉設備時,應用程序不會旋轉。 任何想法將不勝感激!
更新
我還注意到啟動圖像也沒有旋轉(對於iPad,-iPhone不做橫向啟動圖像)。
JMAN的注意事項
我覆蓋了UITabBarController:
@implementation UITabBarController (MyApp)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
if(self.selectedIndex==4)
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
else
return (toInterfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
@end
我首先將其包含在所有視圖控制器中:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
另外,請確保您在Info.plist中支持多種方向。
標簽欄控制器和視圖旋轉
標簽欄控制器默認情況下支持縱向,除非包含的所有視圖控制器均支持橫向,否則它們不會旋轉為橫向。 當設備方向發生變化時,選項卡欄控制器將查詢其視圖控制器數組。 如果其中任何一個都不支持方向,則標簽欄控制器不會更改其方向。
