NSUTF8StringEncoding gives me this %0A%20%20%20%20%22http://example.com/example.jpg%22%0A
- by user1530141
So I'm trying to load pictures from twitter. If i just use the URL in the json results without encoding, in the dataWithContentsOfURL, I get nil URL argument. If I encode it, I get %0A%20%20%20%20%22http://example.com/example.jpg%22%0A. I know I can use rangeOfString: or stringByReplacingOccurrencesOfString: but can I be sure that it will always be the same, is there another way to handle this, and why is this happening to my twitter response and not my instagram response?
i have also tried
stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]
and it does nothing.
this is the url directly from the json...

)
here is my code
if ([post valueForKeyPath:@"entities.media.media_url"]) {
NSString *twitterString = [[NSString stringWithFormat:@"%@", [post valueForKeyPath:@"entities.media.media_url"]]stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
twitterString = [twitterString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(@"%@", twitterString);
if (twitterString != nil){
NSURL *twitterPhotoUrl = [NSURL URLWithString:twitterString];
NSLog(@"%@", twitterPhotoUrl);
dispatch_queue_t queue = kBgQueue;
dispatch_async(queue, ^{
NSError *error;
NSData* data = [NSData dataWithContentsOfURL:twitterPhotoUrl options:NSDataReadingUncached error:&error];
UIImage *image = [UIImage imageWithData:data];
dispatch_sync(dispatch_get_main_queue(), ^{
[streamPhotoArray replaceObjectAtIndex:indexPath.row withObject:image];
cell.instagramPhoto.image = image;
});
});
}
}
