iOS 7中的自定义UIView方向问题
[英]Custom UIView orientation issue in iOS 7
问题描述
我的方式是自定义UIView显示，如我的iPad应用程序中的警报消息在iOS 8及更高版本中正常工作，但iOS 7视图仅在纵向模式下显示？
我的iPad应用程序部署目标是iOS 7，设备方向是仅左侧和右侧。

在你的方法- (CGRect)getBounds
方法UIInterfaceOrientationIsPortrait和UIInterfaceOrientationIsLandscape仅在iOS8上及更高版本
可用性
适用于iOS 8.3及更高版本。
手动检查这些情况
enum UIInterfaceOrientation : Int {
case Unknown
case Portrait
case PortraitUpsideDown
case LandscapeLeft
case LandscapeRight
}

- (CGRect)getBounds {
[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
CGRect screenBounds = [UIScreen mainScreen].bounds;
NSString *ver = [[UIDevice currentDevice] systemVersion];
float ver_float = [ver floatValue];
if (ver_float >= 8.0) {
return screenBounds;
}
CGFloat width = CGRectGetWidth(screenBounds);
CGFloat height = CGRectGetHeight(screenBounds);
UIInterfaceOrientation interfaceOrientation =
[UIApplication sharedApplication].statusBarOrientation;
if (interfaceOrientation == UIInterfaceOrientationPortrait) {
screenBounds.size = CGSizeMake(width, height);
} else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
screenBounds.size = CGSizeMake(height, width);
}
return screenBounds;
}
