需求如下:
1.app整体只能竖屏,部分页面才可以横屏
2.app整体只能竖屏,部分页面也是竖屏,但是点击某个按钮可以使当前页面变为横屏,如全屏视频播放键。
需求1解决方法:
1.在targets - general中设置设备支持方向如下,确保设备各个方法均支持
屏幕快照 2016-12-08 下午6.41.26.png
2.在appdelegate的.h文件声明属性来标记当前设备方向
@property (assign , nonatomic)UIInterfaceOrientation interfaceOrientation;
在appdelegate的.m文件中:
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window { if(self.interfaceOrientation == UIInterfaceOrientationUnknown) { // 直播间用 return UIInterfaceOrientationMaskAllButUpsideDown; } else if(self.interfaceOrientation == UIInterfaceOrientationLandscapeRight) { //交易页面横屏用 return UIInterfaceOrientationMaskLandscapeRight; } else { return UIInterfaceOrientationMaskPortrait; } }
3.在需要横屏的ViewController的ViewWillApper
方法里面:
Appdelegate *delegate =p.p1[UIApplication sharedApplication].delegate; delegate.canRotate = YES;
需求2解决方法:
方法1:
1.在targets - general中设置设备支持方向如下,确保整体都是竖屏

2.在横屏(如button点击)事件处,代码如下
- (void)fullScreenBtnAction { if (_isNormalOrientation) { // 如果当前是默认的竖屏 //注:当前self是UIView对象,如果是VC,则为self.view..... self.frame = CGRectMake(0, 0, kScreenSize.height, kScreenSize.width); CGRect frame = [UIScreen mainScreen].applicationFrame; // transfrom会以当前center为锚点旋转,所以旋转后位置有偏移,需要处理 CGPoint center = CGPointMake(frame.origin.x + ceil(frame.size.width/2), frame.origin.y + ceil(frame.size.height/2)); self.center = center; //取状态栏旋转时间// CGFloat duration = [UIApplication sharedApplication].statusBarOrientationAnimationDuration; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration: 0.3]; self.transform = CGAffineTransformMakeRotation(M_PI_2); [UIView commitAnimations]; } else { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration: 0.3]; self.transform = CGAffineTransformIdentity; [UIView commitAnimations]; //_originRect是进入横屏前self的frame self.frame = _originRect; } _isNormalOrientation = !_isNormalOrientation; //更改状态}
***方法2:
1.在targets - general中设置设备支持方向如下,确保设备各个方法均支持 (弃用 可不设置)

2.在appdelegate的.h文件声明属性interfaceOrientation标记方向
@property (assign , nonatomic)UIInterfaceOrientation interfaceOrientation;
在appdelegate的.m文件中实现设备方向方法:
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window { if(self.interfaceOrientation == UIInterfaceOrientationUnknown) { // 直播间用 return UIInterfaceOrientationMaskAllButUpsideDown; } else if(self.interfaceOrientation == UIInterfaceOrientationLandscapeRight) { //交易页面横屏用 return UIInterfaceOrientationMaskLandscapeRight; } else { return UIInterfaceOrientationMaskPortrait; } }
横竖屏转换:
//转换到竖屏- (void)rotateToPortraitScreenWithInvocation { AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; SEL selector = NSSelectorFromString(@"setOrientation:"); NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocation setSelector:selector]; [invocation setTarget:[UIDevice currentDevice]]; int val = UIDeviceOrientationPortrait; [invocation setArgument:&val atIndex:2]; [invocation invoke]; delegate.interfaceOrientation = UIInterfaceOrientationPortrait; }//转换到横屏模式- (void)rotateToLandscapWithIncovation { AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; delegate.interfaceOrientation = UIInterfaceOrientationUnknown; SEL selector = NSSelectorFromString(@"setOrientation:"); NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocation setSelector:selector]; [invocation setTarget:[UIDevice currentDevice]]; int val = UIInterfaceOrientationLandscapeRight; [invocation setArgument:&val atIndex:2]; [invocation invoke]; }
补充后来自己又折腾的几个Demo:
