获取视图尺寸大小方法

iOS获取屏幕分辨率

获取屏幕分辨率可以两步走

1、得到当前屏幕的尺寸：

CGRect   rect_screen = [[UIScreenmainScreen]bounds];
CGSize   size_screen = rect_screen.size;

2、获得scale：

CGFloat scale_screen = [UIScreen mainScreen].scale;

此时屏幕尺寸的宽高与scale的乘积就是相应的分辨率值。

[[UIScreen mainScreen] bounds]               屏幕大小

 self.view.frame.size.width                       宽度    

 self.view.frame.size.hight                        高度

[UIScreen mainScreen].currentMode.size    真实的设备分辨率

//1 Available in iOS 4.0 and later
UIScreen *MainScreen = [UIScreen mainScreen];
CGSize Size = [MainScreen bounds].size;
CGFloat scale = [MainScreen scale];
CGFloat screenWidth = Size.width * scale;
CGFloat screenHeight = Size.height * scale;

//2 Available in iOS 3.2 and later
UIScreen *MainScreen = [UIScreen mainScreen];
UIScreenMode *ScreenMode = [MainScreen currentMode];
CGSize Size = [ScreenMode size];
CGFloat screenWidth = Size.width;
CGFloat screenHeight = Size.height;

App尺寸，去掉状态栏

屏幕尺寸

CGRect  rx = [ UIScreen mainScreen ].bounds;  //r=0，0，320，480

状态栏尺寸   

CGRect  rect = [[UIApplication sharedApplication] statusBarFrame];
