iOS微信原生分享

首先去微信开放平台注册添加应用

1. 在微信开发平台获取已审核通过的AppId
   微信.开放平台

2. 用CocoaPods集成SDK

   pod 'WechatOpenSDK'
   

3. 添加URL Schemes

4. 添加白名单

代码部分

1. AppDelegate.h中导入#import "WXApi.h"
2. 遵守协议：WXApiDelegate

1. 注册微信

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 注册微信
    [WXApi registerApp:@"wxbbf06491e4a6d0"];
    return YES;
    }
   

2. 跳转处理

    - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{
    return [WXApi handleOpenURL:url delegate:self];
    }
   

3. 微信回调

    - (void)onResp:(BaseResp *)resp{
    /*
    WXSuccess           = 0,   成功
    WXErrCodeCommon     = -1,   普通错误类型
    WXErrCodeUserCancel = -2,   用户点击取消并返回
    WXErrCodeSentFail   = -3,    发送失败
    WXErrCodeAuthDeny   = -4,   授权失败
    WXErrCodeUnsupport  = -5,    微信不支持
    */
    NSString * strMsg = [NSString stringWithFormat:@"errorCode: %d",resp.errCode];
    NSLog(@"strMsg: %@",strMsg);
    NSString * errStr       = [NSString stringWithFormat:@"errStr: %@",resp.errStr];
    NSLog(@"errStr: %@",errStr);
    //判断是微信消息的回调 --> 是支付回调回来的还是消息回调回来的.
   
    if ([resp isKindOfClass:[SendMessageToWXResp class]]){
    // 判断errCode 进行回调处理
    if (resp.errCode == 0){
    nsLog(@"分享成功");
    }
    }
    //发出通知 从微信回调回来之后,发一个通知,让请求支付的页面接收消息,并且展示出来,或者进行一些自定义的展示或者跳转
    NSNotification * notification = [NSNotification notificationWithName:@"WXShare" object:resp.errStr];
    [[NSNotificationCenter defaultCenter] postNotification:notification];
   
    }
   

在分享按钮的控制器.m页面

1. 导入

    scene: 发送的目标场景,可以选择发送到会话(WXSceneSession)或者朋友圈(WXSceneTimeline),默认发送到会话.
    1.分享或收藏的目标场景，通过修改scene场景值实现。
    2.发送到聊天界面——WXSceneSession
    3.发送到朋友圈——WXSceneTimeline
    4.添加到微信收藏——WXSceneFavorite

    /* bText:
    发送消息的类型.包括文本消息和多媒体消息两种.两者只能选择其一.不能同时发送文本和多媒体消息.
    #import "WXApi.h"
    #import "WechatAuthSDK.h"
    #import "WXApiObject.h"
   

2. 接收分享完成回调通知

    - (void)viewDidLoad
    {
    [super viewDidLoad];
   
   
    // 接收分享回调通知
    //监听通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getOrderPayResult:) name:@"WXShare" object:nil];
   
    // 检查是否装了微信
    if ([WXApi isWXAppInstalled]){
   
    }else{
   
    }
    UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.backgroundColor = [UIColor redColor];
    button.frame = CGRectMake(100, 100, 100, 100);
    [button addTarget:self action:@selector(buttonClciked) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button];
   
   
    UIButton * button1 = [UIButton buttonWithType:UIButtonTypeCustom];
    button1.backgroundColor = [UIColor redColor];
    button1.frame = CGRectMake(100, 210, 100, 100);
    [button1 addTarget:self action:@selector(ButtonOneClciked) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button1];
   
   
    UIButton * button2 = [UIButton buttonWithType:UIButtonTypeCustom];
    button2.backgroundColor = [UIColor redColor];
    button2.frame = CGRectMake(100, 320, 100, 100);
    [button2 addTarget:self action:@selector(buttonTwoClciked) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button2];
    }
   
    - (void)getOrderPayResult:(NSNotification *)notification{
    // 注意通知内容类型的匹配
    if (notification.object == 0)
    {
    NSLog(@"分享成功");
    }
    }
