cllocationmanager不要求用戶權限iOS8上

Question

這裏是我的代碼：

if (!_locationManager) 
    { 
     _locationManager = [[CLLocationManager alloc] init]; 
     [_locationManager setDelegate:self]; 
    } 
    [_locationManager startUpdatingLocation]; 

如果有人知道請幫助..謝謝

Answer 1

當您使用位置服務iOS-8.0及以上時，您需要添加一個致電requestWhenInUseAuthorization。找到下面的示例代碼。

locationManager = [[CLLocationManager alloc]init]; 
locationManager.delegate = self; 

// this check is required for iOS 8+ 
// selector 'requestWhenInUseAuthorization' is first introduced in iOS 8 
if ([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) { 
    [locationManager requestWhenInUseAuthorization]; 
} 

[locationManager startUpdatingLocation];

希望這會有所幫助。

添加[locationManager requestAlwaysAuthorization];到您的代碼，並添加條目NSLocationAlwaysUsageDescription與您的.plist價值是某種你想要求用戶許可的消息。
