ios - SendBird - iOS：无法接收相机照片，但可以接收存储的图像

Question

我正在使用 SendBird 向我的应用程序添加发送图片功能。

在- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info我执行此代码时

NSData *imageFileData = UIImageJPEGRepresentation(info[UIImagePickerControllerOriginalImage], 0.5);
NSURL* imagePath = [info objectForKey:@"UIImagePickerControllerReferenceURL"];
NSString* imageName = [imagePath lastPathComponent];

[self.currentChannel sendFileMessageWithBinaryData:imageFileData filename:imageName type:@"image/jpg" size:[imageFileData length] data:nil completionHandler:^(SBDFileMessage * _Nullable fileMessage, SBDError * _Nullable error) {}];

当 imagePicker 的源类型为：时，此代码运行良好UIImagePickerControllerSourceTypePhotoLibrary。

如果我使用 imagePicker 发送图像，其 sourcetype 是：UIImagePickerControllerSourceTypeCamera然后

- (void)channel:(SBDBaseChannel *)sender didReceiveMessage:(SBDBaseMessage *)message永远不会触发。

据我所知，info字典 fromUIImagePickerControllerSourceTypeCamera没有UIImagePickerControllerReferenceURL. 所以， theimagePath和 theimageName必须是nil。

不是的sendFileMessageWithBinaryData:filename:type:size:data:completionHandler:需要。因为您生成 jpeg 数据，所以只需像这样使用：filenamenil@"image.jpg"filename

NSData *imageFileData = UIImageJPEGRepresentation(info[UIImagePickerControllerOriginalImage], 0.5);

[self.currentChannel sendFileMessageWithBinaryData:imageFileData filename:@"image.jpg" type:@"image/jpg" size:[imageFileData length] data:nil completionHandler:^(SBDFileMessage * _Nullable fileMessage, SBDError * _Nullable error) {
}];
