iOS8 - CoreLocation的变化

并在Info.plist中加入两个缺省没有的字段

NSLocationAlwaysUsageDescription

NSLocationWhenInUseUsageDescription

这两个字段没什么特别的意思，就是自定义提示用户授权使用地理定位功能时的提示语。

CLLocationManager  *locationManager = [[CLLocationManager alloc]init];    locationManager.delegate = self;    [locationManager requestAlwaysAuthorization];    locationManager.desiredAccuracy = kCLLocationAccuracyBest;    locationManager.distanceFilter = kCLDistanceFilterNone;    [locationManager startUpdatingLocation];

这是在调用代理

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {    switch (status) {        case kCLAuthorizationStatusNotDetermined:            if ([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {                [locationManager requestWhenInUseAuthorization];            }            break;        default:            break;    }}

这样就Ok了，就会弹出原来的提示框
