I have a web service and I make HTTP calls to it from cocoa using this line of code:
NSData *imageData = [[NSData alloc] initWithContentsOfUrl:url options: NSDataReadingUncached error:&error];
Sometimes is it take 10 seconds, sometimes 30 seconds to load the picture from this URL. I tried loading this URL from a normal browser and it takes 1-2 seconds. I'm doing lazy loading and the problem is the time it takes to load the contents of this URL vs a normal browser. Both tests were done from the same network.
Download.m
NSError *error;
NSData *imageData = [[NSData alloc] initWithContentsOfURL:self.photoRecord.URL options:NSDataReadingUncached error:&error];
NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:imageData options:NSJSONReadingAllowFragments error:&myError];
NSMutableDictionary *pictureInfo = [jsonArray objectAtIndex:0];
NSString *picture;
picture = [pictureInfo valueForKey:@"Picture"];
NSData *base64Data = [[NSData alloc]initWithBase64Encoding:picture];
if (base64Data) {
UIImage *downloadedImage = [UIImage imageWithData:base64Data];
self.photoRecord.image = downloadedImage;
}
[(NSObject *)self.delegate performSelectorOnMainThread:@selector(imageDownloaderDidFinish:) withObject:self waitUntilDone:NO];
Then on the main thread PictureController.m:
-(void) loadScrollViewWithPage:(NSUInteger)page{
....
NSIndexPath *myIndexPath = [NSIndexPath indexPathForRow:page inSection:0];
[self startOperationsForPhotoRecord:aRecord atIndexPath:myIndexPath];
}
- (void)startOperationsForPhotoRecord:(PictureRecord *)record atIndexPath:(NSIndexPath *)indexPath {
Download *imageD = [[Download alloc] initWithPhotoRecord:record atIndexPath:indexPath delegate:self];
[self.pendingOperations.downloadsInProgress setObject:imageD forKey:indexPath];
[self.pendingOperations.downloadQueue addOperation:imageD];
}
Then I have the delegate method to update the UIImageView when the download is done which is working just fine.
The size of the content being loaded is around 400kb.
Any ideas?
