iOS-获取状态栏高度

#define STATUS_H_F \
({\
CGFloat statusBarHeight = 0;\
if (@available(iOS 13.0, *)) {\
    CGFloat topPadding = [UIApplication sharedApplication].windows.firstObject.safeAreaInsets.top;\
    statusBarHeight = topPadding == 0 ? 20.0 : topPadding;\
} else {\
    statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;\
}\
(statusBarHeight);\
})   //状态栏高度

上述方法，在web使用video标签全屏播放视频后，获取到[UIApplication sharedApplication].windows.firstObject.safeAreaInsets.top为0，导致自定义导航栏页面上移，不明所以然。优化后以下代码更为科学：

#define STATUS_H_F \
({\
CGFloat statusBarHeight = 0;\
if (@available(iOS 13.0, *)) {\
    NSSet *set = [UIApplication sharedApplication].connectedScenes;\
    UIWindowScene *windowScene = [set anyObject];\
    UIStatusBarManager *statusBarManager = windowScene.statusBarManager;\
    statusBarHeight = statusBarManager.statusBarFrame.size.height;\
} else {\
    statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;\
}\
(statusBarHeight);\
})   //状态栏高度
