IOS学习笔记2-IOS屏幕 [[UIScreen mainScreen] bounds] 与[UIScreen mainScreen] applicationFrame]区别

2014-03-11 15:41 381 查看
一直对ios设备的尺寸不大敏感，搞不清[[UIScreenmainScreen]bounds]和[UIScreenmainScreen]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：

1
NSLog(@
"[[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）
