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为我的应用添加发送图片功能。

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

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sourcetype为：UIImagePickerControllerSourceTypePhotoLibrary时，此代码很有效。

如果我发送带有imagePicker的图像，其源类型为：UIImagePickerControllerSourceTypeCamera

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

据我所知，info的UIImagePickerControllerSourceTypeCamera字典没有UIImagePickerControllerReferenceURL的对象。因此，imagePath和imageName必须是nil。

sendFileMessageWithBinaryData:filename:type:size:data:completionHandler:需要不是filename的nil。因为你生成了jpeg数据，所以只需使用@"image.jpg"作为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) {
}];
