如何获得ios系统版本号，设备名称

Answer 1

获得IOS系统版本号

[[[UIDevice currentDevice] systemVersion] floatValue]
获得硬件名称

+ (NSString*)getMachine{
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *name = malloc(size);
sysctlbyname("hw.machine", name, &size, NULL, 0);

NSString *machine = [NSString stringWithCString:name encoding:NSUTF8StringEncoding];

free(name);

if( [machine isEqualToString:@"i386"] || [machine isEqualToString:@"x86_64"] ) machine = @"ios_Simulator";
else if( [machine isEqualToString:@"iPhone1,1"] ) machine = @"iPhone_1G";
else if( [machine isEqualToString:@"iPhone1,2"] ) machine = @"iPhone_3G";
else if( [machine isEqualToString:@"iPhone2,1"] ) machine = @"iPhone_3GS";
else if( [machine isEqualToString:@"iPhone3,1"] ) machine = @"iPhone_4";
else if( [machine isEqualToString:@"iPod1,1"] ) machine = @"iPod_Touch_1G";
else if( [machine isEqualToString:@"iPod2,1"] ) machine = @"iPod_Touch_2G";
else if( [machine isEqualToString:@"iPod3,1"] ) machine = @"iPod_Touch_3G";
else if( [machine isEqualToString:@"iPod4,1"] ) machine = @"iPod_Touch_4G";
else if( [machine isEqualToString:@"iPad1,1"] ) machine = @"iPad_1";
else if( [machine isEqualToString:@"iPad2,1"] ) machine = @"iPad_2";

return machine;
