iphone - 如何以编程方式区分 iphone 4 和 iphone 4S？

Question

我正在开发需要检查 iphone 型号的应用程序，但我找不到任何解决方案。我将非常感谢您的任何建议。

Answer 1

这要简单得多。 简单到只需复制和粘贴

此外，我还为机器名称添加了匹配的型号名称。

//MARK: Required import
#import <sys/utsname.h>

+ (NSString*)deviceModelName {

    struct utsname systemInfo;
    uname(&systemInfo);

    NSString *machineName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

    //MARK: More official list is at
    //http://theiphonewiki.com/wiki/Models
    //MARK: You may just return machineName. Following is for convenience

    NSDictionary *commonNamesDictionary =
    @{
