SendBird

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 我执行这段代码

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 的源类型为：UIImagePickerControllerSourceTypePhotoLibrary.

时，此代码运行良好

如果我使用 imagePicker 发送图像，其来源类型是：UIImagePickerControllerSourceTypeCamera 那么

- (void)channel:(SBDBaseChannel *)sender didReceiveMessage:(SBDBaseMessage *)message 从未触发。

Answer 1

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

sendFileMessageWithBinaryData:filename:type:size:data:completionHandler: 需要 filename 而不是 nil。因为您生成 jpeg 数据，所以只需使用 @"image.jpg" 作为 filename，如下所示：

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) {
}];

SendBird - iOS: 无法接收相机照片，但可以接收存储的图像
