如何判断iOS设备硬件型号

Question

如何判断iOS设备型号，比如iPhone5.现在我的做法是写了个宏：#defineiPhone5([UIScreeninstancesRespondToSelector:@selector(currentMode)]?CGSizeEqualToSize(CGSizeMake(640,1136),[[UIScreenmainScreen]currentMode].size):NO)API中直接有方法可以调用吗？

Answer 1

+(NSString*)getMachine{
size_tsize;
sysctlbyname("hw.machine",NULL,&size,NULL,0);
char*name=malloc(size);
sysctlbyname("hw.machine",name,&size,NULL,0);
NSString*machine=[NSStringstringWithCString:nameencoding:NSUTF8StringEncoding];
free(name);
if([machineisEqualToString:@"i386"]||[machineisEqualToString:@"x86_64"])machine=@"ios_Simulator";
elseif([machineisEqualToString:@"iPhone1,1"])machine=@"iPhone_1G";
elseif([machineisEqualToString:@"iPhone1,2"])machine=@"iPhone_3G";
elseif([machineisEqualToString:@"iPhone2,1"])machine=@"iPhone_3GS";
elseif([machineisEqualToString:@"iPhone3,1"])machine=@"iPhone_4";
elseif([machineisEqualToString:@"iPod1,1"])machine=@"iPod_Touch_1G";
elseif([machineisEqualToString:@"iPod2,1"])machine=@"iPod_Touch_2G";
elseif([machineisEqualToString:@"iPod3,1"])machine=@"iPod_Touch_3G";
elseif([machineisEqualToString:@"iPod4,1"])machine=@"iPod_Touch_4G";
elseif([machineisEqualToString:@"iPad1,1"])machine=@"iPad_1";
elseif([machineisEqualToString:@"iPad2,1"])machine=@"iPad_2";
returnmachine;
}历史上是这样的
