Im not quite sure what I am doing wrong here, I have folloed the tutorials to the letter. here is my problem, I have a dictionary called dict which is the result of a TWRequest - I know it contains tweets because of my log details. I am now trying to create an Array of the 'text' element of this but my log says that the array s blank??! Here is my code, any help would be greatly appreciated. Thanks
NSArray *allTweetText = [dict objectForKey:@"text"];
NSLog(@"WHERE IS THIS: %@", allTweetText);
NSString *singleTweet = [allTweetText objectAtIndex:indexPath.row];
NSArray *parsedTweet = [singleTweet componentsSeparatedByString:@":"];
cell.myHeader.text = [parsedTweet objectAtIndex:0];
cell.myDetails.text = [parsedTweet objectAtIndex:1];
cell.myDate.text = [parsedTweet objectAtIndex:2];

For me it looks like you have no key "text" in your dict dictionary. But you have key results. If you execute
NSArray results = [dict objectForKey:@"results"];
you'll get NSArray which contains NSDictionaries. And those nested dictionaries have key "text". So you need to iterate over array results:
NSMutableArray *allTweetText = [NSMutableArray array];
for (NSDictionary *result in results) {
NSString *text = [result objectForKey:@"text"];
[allTweetText addObject:text];
}
