地图二维码的扫描

首先 自动生成:
target ‘mapsaomiao’ do
pod ‘AMap3DMap’
pod ‘AMapSearch’
pod ‘AMapLocation’
pod ‘ZBarSDK’
end

开启权限:
Privacy - Location When In Use Usage Description 使用应用期间允许访问位置信息
Privacy - Location Usage Description 永不允许访问位置信息
Privacy - Location Always Usage Description 始终允许访问位置信息

然后在appdelegate.m里面写:
#import “AppDelegate.h”

#import
@interface AppDelegate ()

@end

@implementation AppDelegate

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [[AMapServices sharedServices] setEnableHTTPS:YES];
  [AMapServices sharedServices].apiKey = @“a5a335fcdb25ee5d71e94e78a9692e9b”;
  return YES;
  }

然后再在viewcontroller.m里面写:

#import “ViewController.h”
#import
#import
#import
#import “ZBarSDK.h”
#define ScreenFrame [[UIScreen mainScreen]bounds]
@interface ViewController ()

@end

@implementation ViewController

  MAMapView *_mapView = [[MAMapView alloc] initWithFrame:self.view.bounds];
