ios版本适配，机型适配，横竖屏适配

1，版本适配： iOS系统的判定，这个可以通过[[[UIDevice currentDevice] systemVersion] floatValue]来获得当前的系统版本。

2，机型适配（屏幕尺寸）：

                           #define DEVICE_IS_IPHONE4S ([[UIScreenmainScreen] bounds].size.height == 480)

                           #define DEVICE_IS_IPHONE5 ([[UIScreenmainScreen] bounds].size.height == 568)

                           #define DEVICE_IS_IPHONE6 ([[UIScreenmainScreen] bounds].size.height == 667)

                           #define DEVICE_IS_IPHONE6_Plus ([[UIScreenmainScreen] bounds].size.height == 960)

3，横竖屏适配：（根据使用layoutSubviews方法，检测横竖屏）

              -（void）layoutSubviews{

                 [super layoutSubviews];

                 UIDeviceOrientation  interfaceOrientation = [[UIApplicationsharedApplication] statusBarOrientation];

                 if(interfaceOrientation ==UIDeviceOrientationPortrait || interfaceOrientation ==UIDeviceOrientationPortraitUpsideDown){

            //翻转为竖屏时

               [self setVerticalFrame];

               }else if (interfacePrientation ==UIDeviceOrientationLandscapeLeft || interfaceOrientation ==UIDeviceOrientationLandscapeRight){

           //翻转为横屏时

               [self setHorizontalFrame];

                 }

             }

 

          -(void)setVerticalFrame

           {

              NSLog(@"竖屏")；

             [titleLable setFrame:CGRectMake(283,0,239,83)];

             [leftView setFrame:CGRectMake(34,102,384,272)];

           }

 

        -(void)setHorizontalFrame

          {

             NSLog(@"横屏")；

             [titleLable setFrame:CGRectMake(183, 0, 239, 83)];

          }
