在写项目的时候&＃xff0c;会遇到很多稀奇古怪的需求&＃xff0c;我就碰到一个写一个网站&＃xff0c;需要强制横屏&＃xff0c;然后不需要上架&＃xff0c;网上看了很多大神的需求&＃xff0c;基本都能实现&＃xff0c;但是不太好用&＃xff0c;
自己参考搞了一个&＃xff0c;代码如下&＃xff1a;
AppDelegate.h
&＃64;property(nonatomic,assign)BOOL allowRotation;//是否允许转向
.m
#pragma mark 支持窗口翻转
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window{if (_allowRotation &＃61;&＃61; YES) {return UIInterfaceOrientationMaskLandscapeRight;}else{return (UIInterfaceOrientationMaskPortrait);}}
横屏展示的viewcontroler&＃xff1a;
.m
- (void)setNewOrientation:(BOOL)fullscreen{if (fullscreen) {NSNumber *resetOrientationTarget &＃61; [NSNumber numberWithInt:UIInterfaceOrientationUnknown];[[UIDevice currentDevice] setValue:resetOrientationTarget forKey:&＃64;"orientation"];NSNumber *orientationTarget &＃61; [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft];[[UIDevice currentDevice] setValue:orientationTarget forKey:&＃64;"orientation"];}else{NSNumber *resetOrientationTarget &＃61; [NSNumber numberWithInt:UIInterfaceOrientationUnknown];[[UIDevice currentDevice] setValue:resetOrientationTarget forKey:&＃64;"orientation"];NSNumber *orientationTarget &＃61; [NSNumber numberWithInt:UIInterfaceOrientationPortrait];[[UIDevice currentDevice] setValue:orientationTarget forKey:&＃64;"orientation"];}}- (void)viewDidLoad {[super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.
AppDelegate * appDelegate &＃61; (AppDelegate *)[UIApplication sharedApplication].delegate;appDelegate.allowRotation &＃61; YES;//(以上2行代码,可以理解为打开横屏开关)
[self setNewOrientation:YES];//调用转屏代码
[self creatWebView];}-(void)creatWebView
{UIWebView *webV &＃61; [[UIWebView alloc]initWithFrame:self.view.frame];[webV loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:&＃64;"https://www.badiu.com"]]];[self.view addSubview:webV];
}
这样的话&＃xff0c;进入的vc直接就是横屏展示了&＃xff0c;我是在这定死了&＃xff0c;只能向右横屏展示&＃xff0c;这个可以自己设置的&＃xff0c;根据重力展示&＃xff0c;如图&＃xff1a;
在上架箭头的地方设置即可&＃xff01;
