uinavigationcontroller – shouldAutorotate,supportedInterfaceOrientations和preferredInterfaceOrientationForPresentation在iOS 7中无法正常

概述我在尝试阻止某些视图中的方向时遇到问题,但代码不是工作属性. 我在每个视图中使用这些行： - (BOOL)shouldAutorotate{ return YES;}- (NSUInteger)supportedInterfaceOrientations{ if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUse 我在尝试阻止某些视图中的方向时遇到问题,但代码不是工作属性.

我在每个视图中使用这些行：

- (BOol)shouldautorotate{    return YES;}- (NSUInteger)supportedInterfaceOrIEntations{    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {        return UIInterfaceOrIEntationMaskPortrait;    } else {        return UIInterfaceOrIEntationMaskAll;    }}- (UIInterfaceOrIEntation)preferredInterfaceOrIEntationForPresentation{    return UIInterfaceOrIEntationPortrait;}

它几乎可以在使用UINavigationController的视图中工作,但是在使用UITabbarController的视图中我遇到了很大的问题,因为它接缝代码没有被调用.

解决方法 好吧我解决了,你必须继承UINavigationController和UITabbarController,所以这里是代码：

//cCustomNavigationController.h file#import <UIKit/UIKit.h>@interface cCustomNavigationController : UINavigationController <UINavigationControllerDelegate>@end//cCustomNavigationController.m file#import "cCustomNavigationController.h"@interface cCustomNavigationController ()@end@implementation cCustomNavigationController - (BOol)shouldautorotate {    return [self.visibleVIEwController shouldautorotate];}- (NSUInteger)supportedInterfaceOrIEntations {    return [self.visibleVIEwController supportedInterfaceOrIEntations];}- (UIInterfaceOrIEntation)preferredInterfaceOrIEntationForPresentation {    return [self.visibleVIEwController preferredInterfaceOrIEntationForPresentation];}@end//cCustomTabController.h file#import <UIKit/UIKit.h>@interface cCustomTabController : UITabbarController <UITabbarControllerDelegate>@end//cCustomTabController.m file#import "cCustomTabController.h"@interface cCustomTabController  ()@end@implementation cCustomTabController- (BOol)shouldautorotate {    return [self.selectedVIEwController shouldautorotate];}- (NSUInteger)supportedInterfaceOrIEntations {    return [self.selectedVIEwController supportedInterfaceOrIEntations];}- (UIInterfaceOrIEntation)preferredInterfaceOrIEntationForPresentation {    return [self.selectedVIEwController preferredInterfaceOrIEntationForPresentation];}@end

现在你只需要在你需要它的地方创建你的TabbarController或者你的NavigationController,即

//For the UINavigationControllerUINavigationController *navigationController = [[cCustomNavigationController alloc] init];//For the UITabbarControllerUITabbarController *tabController = [[cCustomTabController alloc] init];

我希望这能帮到你们.
