高德地图使用和定位

高德定位失败的原因可能是未对iOS8做适配

解决方法是:

1.工程的info.plist添加NSLocationWhenInUseDescription,NSLocationAlwaysUsageDescription字段,不同的字段对应的方法不同

2.在AppDelegate.m中声明个CLLocationManager私有变量,代码如下:

@interface AppDelegate()
{
UINavigationController *_navController;
CLLocationManager *_locationmanager;
}
@end @implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[UIApplication sharedApplication].idleTimerDisabled = TRUE;
_locationmanager = [[CLLocationManager alloc] init];
[_locationmanager requestAlwaysAuthorization]; //NSLocationAlwaysUsageDescription
[_locationmanager requestWhenInUseAuthorization]; //NSLocationWhenInUseDescription
_locationmanager.delegate = self;
}

//ViewController.h文件

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
@interface ViewController : UIViewController<MKMapViewDelegate,CLLocationManagerDelegate>
@end
