使用微信sdk只能发送一张图片:
SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
req.bText = NO;//分享内容带图片和文字时必须为NO
UIImage *image = [UIImage imageNamed:@"opinion"];
WXImageObject *imageObject = [WXImageObject object];
imageObject.imageData = [NSData dataWithContentsOfURL:url];
WXMediaMessage *message = [WXMediaMessage message];
[message setThumbImage:image];
message.mediaObject = imageObject;
//如果分享的内容包括文字和,这个时候的文字不能使用req.text属性来接收,必须使用下边的两个属性
message.title = @"title";
message.description = @"description";
req.message = message; req.scene = WXSceneSession;//好友 //req.scene = WXSceneTimeline;//朋友圈
[WXApi sendReq:req];
/**
* 分享功能
*
* @param context
* 上下文
* @param activityTitle
* Activity的名字
* @param msgTitle
* 消息标题
* @param msgText
* 消息内容
* @param imgPath
* 图片路径，不分享图片则传null
*/
public void shareMsg(String activityTitle, String msgTitle, String msgText,
String imgPath) {
Intent intent = new Intent(Intent.ACTION_SEND);
if (imgPath == null || imgPath.equals("")) {
intent.setType("text/plain"); // 纯文本
} else {
File f = new File(imgPath);
if (f != null && f.exists() && f.isFile()) {
intent.setType("image/jpg");
Uri u = Uri.fromFile(f);
intent.putExtra(Intent.EXTRA_STREAM, u);
}
}
intent.putExtra(Intent.EXTRA_SUBJECT, msgTitle);
intent.putExtra(Intent.EXTRA_TEXT, msgText);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(Intent.createChooser(intent, activityTitle));
}
发送多张图片:
UIImage *image1 = [UIImage imageNamed:@"opinion"];
UIImage *image2 = [UIImage imageNamed:@"current_1"];
NSArray *activityItems = @[image1,image2];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityVC animated:TRUE completion:nil];
activityVC.completionWithItemsHandler = ^(UIActivityType _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {
if (completed) {
}else{
}
};
上面发送多张图片, 是微信iOS APP实现的统一分享功能, 如果在Android就只能发送一张图片
如果需要发送多个媒体文件, 需要使用AccessibilityService, 发送朋友图后, 程序手动选择
媒体.
