判断当前设备的类型 名

1。添加头文件

#import <sys/utsname.h>

#import <sys/types.h>

#import <sys/sysctl.h>

2。 添加代码

 

struct utsname systemInfo;

    uname(&systemInfo);

    NSString *machinename = [NSString StringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

if ([@"iPhone1,1" isEqualToString:machinename])

return iPhone_1;

else if ([@"iPhone1,2" isEqualToString:machinename])

return iPhone_3G;

else if ([@"iPhone2,1" isEqualToString:machinename])

return iPhone_3GS;

else if ([@"iPhone3,1" isEqualToString:machinename] || [@"iPhone3,2" isEqualToString:machinename] || [@"iPhone3,3" isEqualToString:machinename])

return iPhone_4;

else if ([@"iPod1,1" isEqualToString:machinename])

return iPod_1;

else if ([@"iPod2,1" isEqualToString:machinename] || [@"iPod2,2" isEqualToString:machinename])

return iPod_2;

else if ([@"iPod3,1" isEqualToString:machinename])

return iPod_3;

else if ([@"iPod4,1" isEqualToString:machinename])

return iPod_4;

else if (/*[@"iPad1,1" isEqualToString:machinename]*/[machinename hasPrefix:@"iPad"])

return iPad_1;

return unkNown;
