(iOS) get screen size

How to get Screen Size

    int screenSizeW = (int)[[UIScreen mainScreen] bounds].size.width;

    int screenSizeH = (int)[[UIScreen mainScreen] bounds].size.height;

    

    NSLog(@"screen size : %d %d", screenSizeW, screenSizeH);

이렇게 하면 그냥 픽셀단위만 나옴 

레티나등 해상도 대응하려면 여기서 스케일을 곱해줘야함

    int screenSizeW = (int)[[UIScreen mainScreen] bounds].size.width * [[UIScreen mainScreen] scale];

    int screenSizeH = (int)[[UIScreen mainScreen] bounds].size.height * [[UIScreen mainScreen] scale];

    

    NSLog(@"screen size : %d %d", screenSizeW, screenSizeH);
