ios 微信开发

首先依照对应的文档获得对应的key

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

    [WXApi registerApp:@"wxd930ea5d5a258f4f" withDescription:@"demo 2.0"];

    return YES;

}

然后配置对应的url  types

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

注冊想你得到的appkey

之后在点击分享的target事件中加入须要的分享信息和链接

if ( [WXApi isWXAppInstalled]) {//isWXAppInstalled推断是否手机上面有微信

    // 读取图片

    NSData  *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:imageUrl]];

    UIImage *imageNew=[UIImage imageWithData:data];

    if (!data || [imageUrl isEqualToString:@""]||!imageUrl) {

        imageNew = [UIImage imageNamed:@"AM_Logo_Share"];

    }

    imageNew = [self scaleToSize:imageNew size:CGSizeMake(imageNew.size.width*0.9, imageNew.size.height*0.9)];

    data= UIImageJPEGRepresentation(imageNew,1);//调整图片大小的,这个是自己的图片有些大

    if ([data length]> 30*1024) {

        data= UIImageJPEGRepresentation(imageNew,0.1);

    }

    WXMediaMessage *message = [WXMediaMessage message];

    message.title = title;                      分享的tittle

    message.description =des;            分享的详情

    [message setThumbData:data];     分享的图片

    

    WXWebpageObject *ext = [WXWebpageObject object];

    ext.webpageUrl = link;                link是分享的链接

    

    message.mediaObject = ext;

    SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];

    req.bText = NO;

    req.message = message;

    if (type == WeiXin) { //微信好友               推断是分享到朋友圈还是分享到好友

        req.scene = WXSceneSession;

    }else if (type == WXFriends){//朋友圈

        req.scene = WXSceneTimeline;

    }else{

        

    }

    

    [WXApi sendReq:req];

    

}else{

    NSLog(@"还没安装微信");  //以下的是,假设没有微信,提示下在微信或者取消

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"您还没有安装微信" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"下载安装微信", nil];

    [alertView show];

 }

}





- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

    switch (buttonIndex) {

        case 0:

            

            break;

        case 1:

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[WXApi getWXAppInstallUrl]]];

            break;

        default:

            break;

    }

}

//这是自己调整图片大小的方法

- (UIImage *)scaleToSize:(UIImage *)img size:(CGSize)size{

    UIGraphicsBeginImageContext(size);

    [img drawInRect:CGRectMake(0, 0, size.width, size.height)];

    UIImage* scaledImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return scaledImage;

}

之后还要跳转对应第三方app的处理

在APPdelegate里面增加两个方法

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url

{

//凝视的是假设有多个分享,比方qq ,微博等   而WeChatKey,SinaKey 这些是对应的请求得到的appkey

//    if([url.scheme isEqualToString:WeChatKey])

//    {

//        return [WXApi handleOpenURL:url delegate:self];

//    }else if([url.scheme isEqualToString:[NSString stringWithFormat:@"wb%@",SinaKey]])

//    {

//        return [WeiboSDK handleOpenURL:url delegate:self];

//        

//    }else

//    {

//        return [TencentOAuth HandleOpenURL:url];

//    }

    return  [WXApi handleOpenURL:url delegate:self];

}



- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

{

    BOOL isSuc = [WXApi handleOpenURL:url delegate:self];

    return  isSuc;

}

假设要知道你分享的成功和失败,则须要调用

-(void) onReq:(BaseReq*)req

{



}

和

-(void) onResp:(BaseResp*)resp

{

}

这两个方法,在这两个方法内做对应的处理
