我想知道是否可以确定当前设备是哪种 iPhone（例如）？我知道可以通过该模型 NSString *deviceType = [[UIDevice currentDevice] model]; 返回无论我有“iPhone”还是“iPod”，但我想知道是否有可能检测/知道我是否有 iPhone 3GS vs. 和 iPhone 4 vs. iPhone 4S （实际上，我真正想做的就是确定我是否有 3G，因为我正在做相当图形密集型的东西）。
NSString *deviceType = [[UIDevice currentDevice] model];
所以，是的，请告诉我，谢谢！
试试这个库： http: //github.com/erica/uidevice-extension/（作者 Erica Sadun）。（图书馆已有 7-8 年历史，因此已过时）
（示例代码）：
[[UIDevice currentDevice] platformType] // ex: UIDevice4GiPhone [[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"
或者您可以使用此方法：
您可以使用 uname 从 sys/utsname.h 获取设备型号。例如：
Objective-C
#import <sys/utsname.h> // import it in your header or implementation file. NSString* deviceName() { struct utsname systemInfo; uname(&systemInfo); return [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; }
Swift 3
extension UIDevice { var modelName: String { var systemInfo = utsname() uname(&systemInfo) let machineMirror = Mirror(reflecting: systemInfo.machine) let identifier = machineMirror.children.reduce("") { identifier, element in guard let value = element.value as? Int8, value != 0 else { return identifier } return identifier + String(UnicodeScalar(UInt8(value))) } return identifier } } print(UIDevice.current.modelName)
结果应该是：
