问题描述
我正在使用ObjectiveFlickr库从我的iPhone应用程序上传照片到Flickr。我可以授权应用程序并执行一般请求，但我在尝试上传照片时收到错误消息。要上传的照片是使用AVFoundation拍摄的图像。以下是相关代码：
I'm working on using the ObjectiveFlickr library to upload photos to Flickr from my iPhone app. I am able to authorize the app and perform general requests, but I am getting an error while trying to upload a photo. The photo is meant to be uploaded is an image captured using AVFoundation. Here is the relevant code:
UIImage *image = [[UIImage alloc] initWithData:imageData];
if ([[AppDelegate sharedDelegate].apiContext.OAuthToken length]) {
NSData *uploadData = UIImageJPEGRepresentation(image, 1);
if (!flickrRequest) {
flickrRequest = [[OFFlickrAPIRequest alloc] initWithAPIContext:[AppDelegate sharedDelegate].apiContext];
flickrRequest.delegate = self;
flickrRequest.requestTimeoutInterval = 60.0;
}
[flickrRequest uploadImageStream:[NSInputStream inputStreamWithData:uploadData] suggestedFilename:@"Test" MIMEType:@"image/jpeg" arguments:[NSDictionary dictionaryWithObjectsAndKeys:@"0", @"is_public", nil]];
[UIApplication sharedApplication].idleTimerDisabled = YES;
NSLog(@"Can upload photo");
flickrRequest 对象已定义且 @property 'd。在.h文件中与上述代码有关。
The flickrRequest object is defined and @property'd in the .h file pertaining to the code above.
OFFlickrRequestDelegate 方法如下：
- (void)flickrAPIRequest:(OFFlickrAPIRequest *)inRequest imageUploadSentBytes:(NSUInteger)inSentBytes totalBytes:(NSUInteger)inTotalBytes {
NSLog(@"Success");
}
- (void)flickrAPIRequest:(OFFlickrAPIRequest *)inRequest didCompleteWithResponse:(NSDictionary *)inResponseDictionary {
NSLog(@"%s %@ %@", __PRETTY_FUNCTION__, inRequest.sessionInfo, inResponseDictionary);
}
- (void)flickrAPIRequest:(OFFlickrAPIRequest *)inRequest didFailWithError:(NSError *)inError {
NSLog(@"%s %@ %@", __PRETTY_FUNCTION__, inRequest.sessionInfo, inError);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[inError description] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
当我在设备上运行项目时，控制台显示：
When I run the project on the device the console shows:
Can upload photo
Success
Success
Success
Success
flickrAPIRequest:didFailWithError:(null) Error Domain=org.lukhnos.ObjectiveFlickr Code=2147418115 "The operation couldn’t be completed. (org.lukhnos.ObjectiveFlickr error 2147418115.)"
通过API的文档搜索，错误 2147418115 被定义为 OFFlickrAPIRequestFaultyXMLResponseError 。我不太确定这意味着什么。同样奇怪 - 当我只是尝试上传一张照片时，成功出现了四次。
Searching through the API's documentation, "error 2147418115" is defined as "OFFlickrAPIRequestFaultyXMLResponseError". I'm not really sure what this means though. Also strange--"Success" appears four times when I'm only attempting to upload one photo.
使用ObjectiveFlickr的示例应用程序，快照并运行上传照片在我正在测试的同一台设备上。比较我的应用程序与Snap和Run之间的代码，我没有看到任何可能导致照片无法上传的重大差异。
The sample app utilizing ObjectiveFlickr, "Snap and Run" uploads photos fine on the same device that I am testing on. Comparing the code between my app and Snap and Run, I don't see any major differences that could cause the photo not to upload.
非常感谢任何帮助。
推荐答案
这很奇怪。 OFFlickrAPIRequestFaultyXMLResponseError 表示无法将返回的数据解析为XML。如果示例应用程序SnapAndRun正确运行而你的没有，我建议在ObjectiveFlickr.m中添加一行，就在行 NSString * stat = [rsp objectForKey：@stat]之后; ：
That is strange. OFFlickrAPIRequestFaultyXMLResponseError means the returned data cannot be parsed as XML. If the sample app SnapAndRun runs correctly and yours don't, I suggest add one line in ObjectiveFlickr.m, right after the line NSString *stat = [rsp objectForKey:@"stat"];:
NSString *dataString = [[[NSString alloc] initWithData:[request receivedData] encoding:NSUTF8StringEncoding] autorelease];
NSLog(@"received response: %@", dataString);
这可以帮助您找出问题所在（例如，如果它是服务器端问题，或者某些问题）库遗漏的响应格式。）
This may help you find out what goes wrong (e.g. if it's a server-side issue, or some response format that the library missed).
