shows user location在iOS8上不能使用地圖定位

在xcode6中 蘋果地圖得定位方法修改了，以前得不能用了

報錯說明：Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.

解決辦法：

在Supporting Files下得XXX.info.plis裡面添加NSLocationAlwaysUsageDescription 或 NSLocationWhenInUseDescription 兩個String欄位，value可以為空白，也可以設定YES，不過我得問題還是不能解決，最終還是找到得了問題所在，就是info.plist中還需要包含Supported interface orientations 這個Array欄位。然後運行就解決了.

代碼處理：

locationManager = [[CLLocationManager alloc] init];        locationManager.delegate = self;        locationManager.desiredAccuracy=kCLLocationAccuracyBest;        if([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {            [locationManager requestWhenInUseAuthorization];        }        [locationManager startUpdatingLocation];

另外一處：

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {    if (        ([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)] && status != kCLAuthorizationStatusNotDetermined && status != kCLAuthorizationStatusAuthorizedWhenInUse) ||        (![locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)] && status != kCLAuthorizationStatusNotDetermined && status != kCLAuthorizationStatusAuthorized)        ) {        NSString *message = @"您的手機目前未開啟定位服務，如欲開啟定位服務，請至設定開啟定位服務功能";        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"無法定位" message:message delegate:nil cancelButtonTitle:@"確定" otherButtonTitles: nil];        [alertView show];    }else {        [locationManager startUpdatingLocation];    }}

上面那行是 iOS 8 以上，第二行是 iOS 7 以下， kCLAuthorizationStatusAuthorized 在 iOS 8 完全不能使用。

別的地方：

CLAuthorizationStatus status = [CLLocationManager authorizationStatus];        if (status == kCLAuthorizationStatusAuthorizedWhenInUse || status == kCLAuthorizationStatusAuthorized) {    // 開始定位}else {    // 提示警告}
