Question

我已经检查过我的应用中是否启用了运动和健身功能。我检查了下面的代码来检查这个。

if([CMMotionActivityManager isActivityAvailable])
    {
    }

如果在设置中禁用了运动和健身，则返回FALSE。但iPhone 5及更低版本中没有运动和健身选项。所以我想知道设备型号是iPhone 5s还是更高版本。有没有办法检查这个？

如果要查看动作，请使用

https://developer.apple.com/library/prerelease/ios/documentation/CoreMotion/Reference/CMSensorRecorder_class/index.html#//apple_ref/occ/clm/CMSensorRecorder/isAuthorizedForRecording

iOS 9及更高版本，CMSensorRecorder类，其中介绍了检查您的应用是否获得Motion＆amp;健身：

如果您正在使用Swift，请使用以下

class`func isAuthorizedForRecording（） - ＆gt;布尔

如果目标C那么

+ (BOOL)isAuthorizedForRecording

如果您只是想检查设备型号，请使用以下方法

[[UIDevice currentDevice] platformType]   // ex: UIDevice4GiPhone
[[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"

获取模型的完整列表

#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];
}

打印设备名称后，您将获得以下输出之一
