IOS代码判断设备类型
判断IOS设备类型一般会使用
//设备名称
return [UIDevice currentDevice].name;
//设备型号，只可得到是何设备，无法得到是第几代设备
return [UIDevice currentDevice].model;
//系统版本型号,如iPhone OS
return [UIDevice currentDevice].systemVersion;
//系统版本名称，如6.1.3
return [UIDevice currentDevice].systemName;
但是，这样只能区分iPhone，iPad
真正能够实现设备类型区分的方法如下
#import
NSString*
machineName()
{
struct utsname systemInfo;
uname(&systemInfo);
return [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
} 结果可能为如下的以逗号分隔的字符串
@"i386" on the simulator
@"iPod1,1" on iPod Touch
@"iPod2,1" on iPod Touch Second Generation
@"iPod3,1" on iPod Touch Third Generation
@"iPod4,1" on iPod Touch Fourth Generation
@"iPhone1,1" on iPhone
@"iPhone1,2" on iPhone 3G
@"iPhone2,1" on iPhone 3GS
@"iPad1,1" on iPad
@"iPad2,1" on iPad 2
@"iPad3,1" on 3rd Generation iPad
@"iPhone3,1" on iPhone 4
@"iPhone4,1" on iPhone 4S
@"iPhone5,1" on iPhone 5 (model A1428, AT&T/Canada)
@"iPhone5,2" on iPhone 5 (model A1429, everything else)
@"iPad3,4" on 4th Generation iPad
@"iPad2,5" on iPad Mini
@"iPhone5,3" on iPhone 5c (model A1456, A1532 | GSM)
@"iPhone5,4" on iPhone 5c (model A1507, A1516, A1526 (China), A1529 | Global)
@"iPhone6,1" on iPhone 5s (model A1433, A1533 | GSM)
@"iPhone6,2" on iPhone 5s (model A1457, A1518, A1528 (China), A1530 | Global)
@"iPad4,1" on 5th Generation iPad (iPad Air) - Wifi
@"iPad4,2" on 5th Generation iPad (iPad Air) - Cellular
@"iPad4,4" on 2nd Generation iPad Mini - Wifi
@"iPad4,5" on 2nd Generation iPad Mini - Cellular为了简化代码，网上找到了如下实现，是通过NSDictionary实现快速查询
#import
NSString *machineName()
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@"iOSDeviceModelMapping" ofType:@"plist"];
NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];
NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
return [iOSDevices valueForKey:deviceModel];
} 在xCode解决方案中添加以 iOSDeviceModelMapping.plist命名的plist文件，内容如下
x86_64

当MachineName方法时，NSDictionary通过匹配key，即utsname.machine的值，判断设备类型。
网上找到的类似的解决方法
#import
- (NSString*) deviceName
{
struct utsname systemInfo;
uname(&systemInfo);
NSString* code = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
static NSDictionary* deviceNamesByCode = nil;
if (!deviceNamesByCode) {
deviceNamesByCode = @{@"i386" :@"Simulator",
@"iPod1,1" :@"iPod Touch", // (Original)
@"iPod2,1" :@"iPod Touch", // (Second Generation)
@"iPod3,1" :@"iPod Touch", // (Third Generation)
@"iPod4,1" :@"iPod Touch", // (Fourth Generation)
@"iPhone1,1" :@"iPhone", // (Original)
@"iPhone1,2" :@"iPhone", // (3G)
@"iPhone2,1" :@"iPhone", // (3GS)
@"iPad1,1" :@"iPad", // (Original)
@"iPad2,1" :@"iPad 2", //
@"iPad3,1" :@"iPad", // (3rd Generation)
@"iPhone3,1" :@"iPhone 4", //
@"iPhone4,1" :@"iPhone 4S", //
@"iPhone5,1" :@"iPhone 5", // (model A1428, AT&T/Canada)

@"iPhone6,2" :@"iPhone 5s", // (model A1457, A1518, A1528 (China), A1530 | Global)
@"iPad4,1" :@"iPad Air", // 5th Generation iPad (iPad Air) - Wifi
@"iPad4,2" :@"iPad Air", // 5th Generation iPad (iPad Air) - Cellular
@"iPad4,4" :@"iPad Mini", // (2nd Generation iPad Mini - Wifi)
@"iPad4,5" :@"iPad Mini" // (2nd Generation iPad Mini - Cellular)
};
}
NSString* deviceName = [deviceNamesByCode objectForKey:code];
if (!deviceName) {
// Not found on database. At least guess main device type from string contents:
if ([deviceName rangeOfString:@"iPod"].location != NSNotFound) {
deviceName = @"iPod Touch";
}
else if([deviceName rangeOfString:@"iPad"].location != NSNotFound) {
deviceName = @"iPad";
}
else if([deviceName rangeOfString:@"iPhone"].location != NSNotFound){
deviceName = @"iPhone";
}
}
return deviceName;
}
// (rest of class implementation omitted)
@end 后面加个获取系统版本号的，好记心不如烂笔头
NSLog(@"System Name: %@", [[UIDevice currentDevice] systemName]); //"iPhone OS"
NSLog(@"System Version: %@", [[UIDevice currentDevice] systemVersion]); //7.0.3
