iOS开发 关于ios14系统以上状态栏高度改变的问题之前状态栏高度：有刘海屏iPhone为44，无刘海屏为20。 但是从ios14开始有刘海屏的iPhone状态栏高度不一定是44了。如： iPhoneXR,iPhone11 状态栏高度为48， iPhone X，iPhone 11 Pro，iPhone 11 Pro Max，iPhone 12 mini，状态栏高度44， iPhone 12，iPhone 12 Pro，iPhone 12 Pro Max，状态栏高度为47.
iPhone 13 mini状态栏高度为50，
iPhone 13，iPhone 13 Pro，iPhone 13 Pro Max，状态栏高度为47. 所以之前项目中如果是写固定值的状态栏高度为44的宏就不适用了。 替换为以下宏：
#define phoneStatusHeight ({CGFloat statusBarHeight = 0.0;if (@available(iOS 13.0, *)) {statusBarHeight = [UIApplication sharedApplication].windows.firstObject.windowScene.statusBarManager.statusBarFrame.size.height;} else { statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;}(statusBarHeight);})
