UINavigationController、UITabBarController 支持屏幕自动旋转问题

来源：互联网发布：clint eastwood 知乎编辑：程序博客网时间：2024/05/19 01:10

写了一篇关于屏幕强制旋转的文章，可是有人跟我反应说没成功，状态栏依旧没有改变。原因是他的rootViewController是UINavigationController跟UITabBarController混合使用的。

因为UINavigationController跟UITabBarController也是UIViewController，所以会覆盖其子页面的旋转方法。

解决方法：添加以下类

////  UINavigationController+Rotation_IOS6.m//  djy////  Created by SuFuTe on 14/12/30.//  Copyright (c) 2014年 SuFuTe. All rights reserved.//#import "UINavigationController+Rotation_IOS6.h"@implementation UINavigationController (Rotation_IOS6)-(BOOL)shouldAutorotate {        NSLog(@"UINavigationController 100");    // 不想其子页面支持旋转， 可直接返回 NO    return YES;}-(NSUInteger)supportedInterfaceOrientations {    NSLog(@"UINavigationController 200");    return [[self.viewControllers lastObject] supportedInterfaceOrientations];}- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {    NSLog(@"UINavigationController 300");    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];}@end

////  UITabBarController+Rotation_IOS6.m//  djy////  Created by SuFuTe on 14/12/30.//  Copyright (c) 2014年 SuFuTe. All rights reserved.//#import "UITabBarController+Rotation_IOS6.h"@implementation UITabBarController (Rotation_IOS6)-(BOOL)shouldAutorotate {    NSLog(@"UITabBarController 100");    // 不想其子页面支持旋转，可直接返回 NO    return YES;}-(NSUInteger)supportedInterfaceOrientations {    NSLog(@"UITabBarController 200");    //return UIInterfaceOrientationMaskPortrait;    return [[self.viewControllers lastObject] supportedInterfaceOrientations];}- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {    NSLog(@"UITabBarController 300"); //return UIInterfaceOrientationPortrait;    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];}@end

AppDelegate.m中导入头文件

#import "UINavigationController+Rotation_IOS6.h"#import "UITabBarController+Rotation_IOS6.h"

在想要旋转的页面重写以下方法，设置你想要的旋转方向

-(BOOL)shouldAutorotate;-(NSUInteger)supportedInterfaceOrientations;-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;
