ios8定位问题（建议CLLocationManager 和MKMapView 结合使用）

1.在info.plist中添加key NSLocationWhenInUseUsageDescription、NSLocationAlwaysUsageDescription。

2.CLLocationManager 切记定义成成员变量、或者属性，否则导致不弹出系统提示打开定位提示框

3.直接上代码

#pragma mark - CLLocationManagerDelegate

- (void)startLocation{

self.locationmanager = [[CLLocationManager alloc] init];

self.locationmanager.delegate = self;

}

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{

switch (status) {

case kCLAuthorizationStatusNotDetermined:

if([self.locationmanager respondsToSelector:@selector(requestAlwaysAuthorization)]){

[self.locationmanager requestWhenInUseAuthorization];

}

break;

case kCLAuthorizationStatusDenied:

[UIAlertView bk_alertViewWithTitle:@"请在设置-隐私-定位服务中开启定位功能！"];

break;

case kCLAuthorizationStatusRestricted:

[UIAlertView bk_alertViewWithTitle:@"定位服务无法使用！"];

default:

break;

}

}

4.开启定位后直接使用MKMapView定位。
