关于获取ios系统版本号 与 获取iphone设备型号的相关代码搜集

      一、获取iOS设备的型号     

// 需要#import "sys/utsname.h"
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceString = [ NSString stringWithCString:systemInfo.machine encoding: NSUTF8StringEncoding ];

    if ([deviceString isEqualToString:@ "iPhone1,1" ])
return @ "iPhone 1G" ;
    if ([deviceString isEqualToString:@ "iPhone1,2" ])
return @ "iPhone 3G" ;
    if ([deviceString isEqualToString:@ "iPhone2,1" ])
return @ "iPhone 3GS" ;
    if ([deviceString isEqualToString:@ "iPhone3,1" ])
return @ "iPhone 4" ;
    if ([deviceString isEqualToString:@ "iPhone4,1" ])
return @ "iPhone 4S" ;
    if ([deviceString isEqualToString:@ "iPhone5,2" ])
return @ "iPhone 5" ;
    if ([deviceString isEqualToString:@ "iPhone3,2" ])
return @ "Verizon iPhone 4" ;
    if ([deviceString isEqualToString:@ "iPod1,1" ])
return @ "iPod Touch 1G" ;
    if ([deviceString isEqualToString:@ "iPod2,1" ])
return @ "iPod Touch 2G" ;
    if ([deviceString isEqualToString:@ "iPod3,1" ])
return @ "iPod Touch 3G" ;
    if ([deviceString isEqualToString:@ "iPod4,1" ])
return @ "iPod Touch 4G" ;
    if ([deviceString isEqualToString:@ "iPad1,1" ])
return @ "iPad" ;
    if ([deviceString isEqualToString:@ "iPad2,1" ])
return @ "iPad 2 (WiFi)" ;
    if ([deviceString isEqualToString:@ "iPad2,2" ])
return @ "iPad 2 (GSM)" ;
    if ([deviceString isEqualToString:@ "iPad2,3" ])
return @ "iPad 2 (CDMA)" ;
    if ([deviceString isEqualToString:@ "i386" ])
return @ "Simulator" ;
    if ([deviceString isEqualToString:@ "x86_64" ])
return @ "Simulator" ;
    NSLog (@ "NOTE: Unknown device type: %@" , deviceString);
    return deviceString;


二、 另一种更加暴力的获取设备型号的方法就是直接去读屏幕的长宽
#define IS_IPHONE5 (([[UIScreen mainScreen] bounds].size.height == 568) ? YES : NO) #define IS_IPhone6 (667 == [[UIScreen mainScreen] bounds].size.height ? YES : NO) #define IS_IPhone6plus (736 == [[UIScreen mainScreen] bounds].size.height ? YES : NO) 这种方法的好处是更加直接，代码量也少，但是缺点在于 如果没有适配大屏，分辨率永远是 568。


三、获得Ios系统版本号的函数copy + (float)getIOSVersion   {       return [[[UIDevice currentDevice] systemVersion] floatValue];   }
