关于百度地图定位

首先先导入4个配置文件

#import "AppDelegate.h"#import#import@interface AppDelegate ()

@end

static NSString *APIKey =@"b12a81f5c32c3f061ad8489f079c83d3";

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    [AMapServices sharedServices].apiKey =APIKey;

    return YES;

}

导入必要的几个类库

视图页面：

#import "ViewController.h"
#import <AMapLocationKit/AMapLocationKit.h>
#import <MAMapKit/MAMapKit.h>

#define DefaultLocationTimeout 6
#define DefaultReGeocodeTimeout 3
@interface ViewController ()<MAMapViewDelegate,AMapLocationManagerDelegate>
@property(nonatomic,strong)MAMapView *mapView;
@property(nonatomic,strong)AMapLocationManager *locationManager;
@property(nonatomic,copy)AMapLocatingCompletionBlock completionBlock;
@end

@implementation ViewController
