目标集属性，多个调用

Question

我不能在ObjectiveFlickr中设置元数据和位置

如果我只做了一次，它会很好，但如果两者都做，它只做第一次。

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

{ PRETTY_FUNCTION，NSLog(%s %@，NSLog 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;       

}

}

您需要定义一个新步骤(例如: NSString *kSetImageGeoInfoStep = @"kSetImageGeoInfoStep")，并通过在if/else块中添加一个附加条件来容纳geo更新，从而将sessionInfo设置为这个新步骤。代码应该如下所示(免责声明--而不是编译，因此语法错误是可能的：

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;       

}
