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