[[UIScreen mainScreen] bounds]和 applicationFrame

一直对ios设备的尺寸不大敏感，搞不清[[UIScreen mainScreen] bounds] 和[UIScreen mainScreen] applicationFrame]的区别，故总是心虚，现扫盲下：

定义一个宏：

1#define PrintRect(frame) NSLog(@"X:%f,Y:%f,W:%f,H:%f",frame.origin.x,frame.origin.y,frame.size.width,frame.size.height)

测试调用：

1NSLog(@"[[UIScreen mainScreen] bounds]");
2 PrintRect([[UIScreen mainScreen] bounds]);
3     
4 NSLog(@"[[UIScreen mainScreen] applicationFrame]");
5 PrintRect([[UIScreen mainScreen]applicationFrame]);

测试结果：

从日志输出可以看到，bounds就是屏幕的全部区域，applicationFrame就是app显示的区域，不包含状态栏（高度20，如果状态栏隐藏的话，那么，这个结果就和bounds一样了）
