ios单个ViewController屏幕旋转

作者：佚名      IOS开发编辑：admin      更新时间：2022-07-23

如果需要旋转的ViewController 使用了UINavigationController，对UINavigationController进行如下扩展

@implementation UINavigationController(shouldAutorotate)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (BOOL)shouldAutorotate
{
 return self.topViewController.shouldAutorotate;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return self.topViewController.supportedInterfaceOrientations;
}

@end

需要旋转的ViewController设置

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return YES;
}

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

 

其他不需要旋转的 ViewController设置，建议添加BaseViewController统一控制

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)shouldAutorotate
{
    return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationPortrait;
}
