iOS-微信-分享

一.微信原生的分享--准备工作.

1. 需要申请微信AppId.

2. 导入系统架包.

SDK文件包括 libWeChatSDK.a，WXApi.h，WXApiObject.h,WechatAuthSDK.四个.

3.导入必要的系统库.

     SystemConfiguration.framework,

     libz.dylib,

     libsqlite3.0.dylib,

     libc++.dylib,

     CoreTelephoy.framework (坑一: 这个库是必要的,但是微信官方文档中没有说到要导入)

4. 该项目中的Bundle Identifier 应该填向微信注册的Bundle Identifier

5. 注册微信 (回调的时候用到,告诉微信,从微信返回到哪个APP)

 Target --> info --> URL Types --> +按钮 --> 填写identifier 和 URL Schemes. 前一个是标识符,一般填@"weixin".后一个是注册的微信appId. 比如"wx19a984b788a8a0b1".(注释: 假的appid)

 6. 添加微信白名单

  info.plist --> 右击 --> open as  --> source Code --> 添加白名单

我是在<key>CFBundleVersion</key>这一行上面添加的. 注意保持正确的键值对.别插错了.

二. 代码部分.

1.

AppDelegate.h中

(1) 导入

#import "WXApi.h"

 (2) 遵守协议

WXApiDelegate

2. WXApiDelegate.m中

1.注册微信

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    // 注册微信
    [WXApi registerApp:@"wxbbf0646591e4a6d0" withDescription:@"测试"];
    return YES;
}

2.跳转处理

//被废弃的方法. 但是在低版本中会用到.建议写上
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [WXApi handleOpenURL:url delegate:self];
}
//被废弃的方法. 但是在低版本中会用到.建议写上

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    return [WXApi handleOpenURL:url delegate:self];
}

//新的方法
- (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

{

    NSString * strMsg = [NSString stringWithFormat:@"errorCode: %d",resp.errCode];

    NSLog(@"strMsg: %@",strMsg);

    NSString * errStr       = [NSString stringWithFormat:@"errStr: %@",resp.errStr];

    NSLog(@"errStr: %@",errStr);

    NSString * strTitle;

    //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]])

    {

        strTitle = [NSString stringWithFormat:@"发送媒体消息的结果"];

    }

    NSString * wxPayResult;

    //判断是否是微信支付回调 (注意是PayResp 而不是PayReq)

    if ([resp isKindOfClass:[PayResp class]])

    {

        //支付返回的结果, 实际支付结果需要去微信服务器端查询

        strTitle = [NSString stringWithFormat:@"支付结果"];

        switch (resp.errCode)

        {

            case WXSuccess:

            {

                strMsg = @"支付结果:";

                NSLog(@"支付成功: %d",resp.errCode);

                wxPayResult = @"success";

                break;

            }

            case WXErrCodeUserCancel:

            {

                strMsg = @"用户取消了支付";

                NSLog(@"用户取消支付: %d",resp.errCode);

                wxPayResult = @"cancel";

                break;

            }

            default:

            {

                strMsg = [NSString stringWithFormat:@"支付失败! code: %d  errorStr: %@",resp.errCode,resp.errStr];

                NSLog(@":支付失败: code: %d str: %@",resp.errCode,resp.errStr);

                wxPayResult = @"faile";

                break;

            }

        }

        //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:@"WXPay" object:wxPayResult];

        [[NSNotificationCenter defaultCenter] postNotification:notification];

    }

}

3.在分享按钮的控制器.m页面

(1) 导入

 #import "WXApi.h"

#import "WechatAuthSDK.h"

#import "WXApiObject.h"

(2) 分享文字

- (void)buttonClciked
{
    SendMessageToWXReq * req = [[SendMessageToWXReq alloc] init];
    req.text = @"分享的内容";
    req.bText = YES;
    req.scene = WXSceneSession;
    [WXApi sendReq:req];
}

(3)分享图文

- (void)ButtonOneClciked
{
    //
    WXMediaMessage * message = [WXMediaMessage message];
    [message setThumbImage:[UIImage imageNamed:@"seeall@1x"]];
    
    WXImageObject * imageObject = [WXImageObject object];
    NSString * filePath = [[NSBundle mainBundle] pathForResource:@"seeall@1x" ofType:@"png"];
    imageObject.imageData = [NSData dataWithContentsOfFile:filePath];
    message.mediaObject = imageObject;
    
    SendMessageToWXReq * req = [[SendMessageToWXReq alloc] init];
    req.bText = NO;
    req.message = message;
    req.scene = WXSceneTimeline;
    [WXApi sendReq:req];
}

(4)分享链接

- (void)buttonTwoClciked
{
    WXMediaMessage * message = [WXMediaMessage message];
    message.title = @"标题";
    message.description = @"副标题";
    [message setThumbImage:[UIImage imageNamed:@"seeall@1x"]];
    
    WXWebpageObject * webpageObject = [WXWebpageObject object];
    webpageObject.webpageUrl = @"www.baidu.com";
    message.mediaObject = webpageObject;
    
    SendMessageToWXReq * req = [[SendMessageToWXReq alloc] init];
    req.bText = NO;
    
    req.message = message;
    req.scene = WXSceneSession;
    
    [WXApi sendReq:req];
}
