闲话不多说先上效果图
这里面用的present�页面切换
1.先在AppDelegate中重写-(UIInterfaceOrientationMask)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window方法，交代进入的BaseNavi，以及RootView。代码如下
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
// Override point for customization after application launch.
self.window= [[UIWindowalloc]initWithFrame:[[UIScreenmainScreen]bounds]];
[self.windowsetBackgroundColor:[UIColorwhiteColor]];
UIStoryboard*storyBoard = [UIStoryboardstoryboardWithName:@"Main"bundle:[NSBundlemainBundle]];
ViewController*vc = [storyBoardinstantiateViewControllerWithIdentifier:@"ViewController"];
BaseViewController* nav = [[BaseViewControlleralloc]initWithRootViewController:vc];
[self.windowsetRootViewController:nav];
[self.windowmakeKeyAndVisible];
returnYES;
}
-(UIInterfaceOrientationMask)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window{
returnUIInterfaceOrientationMaskAll;
}
2.创建一个BaseNavi，就是上一步用到的。方法写上
- (BOOL)shouldAutorotate
{
return[self.topViewControllershouldAutorotate];
}
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return[self.topViewControllersupportedInterfaceOrientations];
}
3.在第一个页面写上，支持旋转 但是这个页面只支持竖屏，代码：
//支持旋转
-(BOOL)shouldAutorotate{
returnYES;
}
//支持的方向因为界面A我们只需要支持竖屏
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
returnUIInterfaceOrientationMaskPortrait;
}
4.第二个页面我们写上，我们所需要的横屏效果，代码：
//支持旋转
-(BOOL)shouldAutorotate{
returnYES;
}
//
//支持的方向
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
returnUIInterfaceOrientationMaskLandscapeLeft;
}
//一开始的方向很重要
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
returnUIInterfaceOrientationLandscapeLeft;
}
以上就是横屏设置了，代码不到位的，请多包涵。
