檢查運動和健身選項是可用的設置

Question

我已檢查是否運動&健身已啓用在我的應用程序。我檢查了下面的代碼來檢查這個。

if([CMMotionActivityManager isActivityAvailable]) 
    { 
    } 

當運動&健身在設置中被禁用時返回FALSE。但運動&健身選項是不存在於iPhone 5及更低版本。所以我想知道設備型號是iPhone 5s還是更高。有什麼方法可以檢查嗎？

如果你想查詢的運動，然後使用

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

的iOS 9以上，CMSensorRecorder類，在他們介紹的方法來檢查，如果您的應用程序被授權爲運動&健身：

如果您使用的是Swift，請使用以下代碼

class`func isAuthorizedForRecording（） - > Bool

如果目標C然後

+ (BOOL)isAuthorizedForRecording 

---

，如果你只是想檢查設備模型，然後用下面的方法

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

，這是讓打印後模型

#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]; 
}
