ios - 在纵向和横向模式下获得相同的屏幕宽度和高度

我已经使用此代码来获取屏幕宽度和屏幕高度，

    float scaleFactor = [[UIScreen mainScreen] scale];
    CGRect screen = [[UIScreen mainScreen] bounds];
    CGFloat widthInPixel = screen.size.width * scaleFactor;
    CGFloat heightInPixel = screen.size.height * scaleFactor;

    NSLog(@"%f",widthInPixel);
    NSLog(@"%f",heightInPixel);

和

    CGRect screenBounds = [[UIScreen mainScreen] bounds];
    NSLog(@"screenBounds W %f",screenBounds.size.width);
    NSLog(@"screenBounds H %f",screenBounds.size.height);

但是对于纵向和横向模式，其显示的宽度均为768，高度为1024。

最佳答案

这将为您提供良好的解释-How to get orientation-dependent height and width of the screen?

和为建议的Here's a handy macro:定义宏的方法之一。

#define SCREEN_WIDTH(UIInterfaceOrientationIsPortrait([UIApplication sharedApplication] .statusBarOrientation)？[[UIScreen mainScreen] bounds] .size.width:[[UIScreen mainScreen] bounds] .size.height)
#define SCREEN_HEIGHT(UIInterfaceOrientationIsPortrait([UIApplication sharedApplication] .statusBarOrientation)？[[UIScreen mainScreen] bounds] .size.height:[[UIScreen mainScreen] bounds] .size.width)
