我就直接贴代码了，copy后放入按钮中即可用

-(void)shareWXButton{

    UIImage *image = [self snapsHotView:self.view];

    NSData* imageData = UIImagePNGRepresentation(image);

    WXImageObject *imageObject = [WXImageObject object];

    imageObject.imageData = imageData;

    WXMediaMessage *message = [WXMediaMessage message];

    message.mediaObject = imageObject;

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

    req.bText = NO;

    req.message = message;

    req.scene = WXSceneTimeline;

    [WXApi sendReq:req completion:^(BOOL success) {

        NSLog(@"分享完成");

    }];

}

- (UIImage*)snapsHotView:(UIView *)view{

    UIGraphicsBeginImageContextWithOptions(view.bounds.size,NO,[UIScreen mainScreen].scale);

    [view drawViewHierarchyInRect:view.bounds afterScreenUpdates:NO];

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return image;

}

问题一：点击按钮后直接显示分享成功，不跳转微信。

问题二： PBItemCollectionServicer connection disconnected. 报错。

问题三：由于不支持的分享类型，【返回(未审核应用)】。
