我无法在 ObjectiveFlickr 中设置 Meta 和设置位置

如果我只做一个，它可以正常工作，但如果我两个都做，它只会做第一个

- (void)flickrAPIRequest:(OFFlickrAPIRequest *)inRequest didCompleteWithResponse:(NSDictionary *)inResponseDictionary

{ NSLog(@"%s %@ %@", PRETTY_FUNCTION, inRequest.sessionInfo, inResponseDictionary);

if (inRequest.sessionInfo == kUploadImageStep) {
    snapPictureDescriptionLabel.text = @"Setting properties...";


    NSLog(@"%@", inResponseDictionary);
    NSString *photoID = [[inResponseDictionary valueForKeyPath:@"photoid"] textContent];

    flickrRequest.sessionInfo = kSetImagePropertiesStep;
    [flickrRequest callAPIMethodWithPOST:@"flickr.photos.setMeta" arguments:[NSDictionary dictionaryWithObjectsAndKeys:photoID, @"photo_id", @"Snap and Run", @"title", @"Uploaded from my iPhone/iPod Touch", @"description", nil]];        
    flickrRequest.sessionInfo = kSetImagePropertiesStep;
    [flickrRequest callAPIMethodWithPOST:@"flickr.photos.geo.setLocation" arguments:[NSDictionary dictionaryWithObjectsAndKeys:photoID, @"photo_id",@"34" ,@"lat",@"-118",@"lon", nil]];                        



}
else if (inRequest.sessionInfo == kSetImagePropertiesStep) {
    [self updateUserInterface:nil];     
    snapPictureDescriptionLabel.text = @"Done";

    [UIApplication sharedApplication].idleTimerDisabled = NO;       

}

}

【解决方案1】：

您需要定义一个新步骤（例如：NSString *kSetImageGeoInfoStep = @"kSetImageGeoInfoStep"）并通过在 if/else if 块中添加一个附加条件来将 sessionInfo 设置为这个新步骤以适应地理信息更新。代码应如下所示（免责声明 - 未编译，因此可能出现语法错误：

if (inRequest.sessionInfo == kUploadImageStep) {
    snapPictureDescriptionLabel.text = @"Setting properties...";


    NSLog(@"%@", inResponseDictionary);
    NSString *photoID = [[inResponseDictionary valueForKeyPath:@"photoid"] textContent];
    [photoID retain];

    flickrRequest.sessionInfo = kSetImagePropertiesStep;
    [flickrRequest callAPIMethodWithPOST:@"flickr.photos.setMeta" arguments:[NSDictionary dictionaryWithObjectsAndKeys:photoID, @"photo_id", @"Snap and Run", @"title", @"Uploaded from my iPhone/iPod Touch", @"description", nil]];            

}
else if (inRequest.sessionInfo == KSetImagePropertiesStep) {
    snapPictureDescriptionLabel.text = @"Setting Geo info..."; 
    flickrRequest.sessionInfo = kSetImageGeoInfoStep;
    [flickrRequest callAPIMethodWithPOST:@"flickr.photos.geo.setLocation" arguments:[NSDictionary dictionaryWithObjectsAndKeys:photoID, @"photo_id",@"34" ,@"lat",@"-118",@"lon", nil]];                        
}
else if (inRequest.sessionInfo == kSetImageGeoInfoStep) {
    [self updateUserInterface:nil];     
    snapPictureDescriptionLabel.text = @"Done";
    [photoID release];
    photoID = nil;

    [UIApplication sharedApplication].idleTimerDisabled = NO;       

}
