iOS设置只支持某个界面横屏
注意：首先Device Orientation哪里只勾选：Portrait，其他的都不要勾选。
一、指定某个界面横屏
AppDelegate.h
@property (nonatomic,assign)NSInteger allowRotate;
AppDelegate.m
//此方法会在设备横竖屏变化的时候调用
-
(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{// NSLog(@"方向 ============= %ld", _allowRotate);
if (_allowRotate == 1) {
return UIInterfaceOrientationMaskAll;
}else{
return (UIInterfaceOrientationMaskPortrait);
}
}
// 返回是否支持设备自动旋转
- (BOOL)shouldAutorotate
{
if (_allowRotate == 1) {
return YES;
}
return NO;
}
二、基类
//将要出现
-(void)viewWillAppear:(BOOL)animated{
//设置成竖屏
AppDelegate * delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
delegate.allowRotate = 0;
}
三、要竖屏的控制器里这样写
//将要出现
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
//设置成支持横屏
AppDelegate * delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
delegate.allowRotate = 1;
} 这里也推荐一些面试相关的内容！
