following is the ios code that i used to parse
jsonurl=[NSURL URLWithString:#"https://api.twitter.com/1/statuses/user_timeline.json?screen_name=#SrBachchan&count=10"];
jsonData=[[NSString alloc]initWithContentsOfURL:jsonurl];
jsonArray = [jsonData objectFromJSONString];
items = [jsonArray objectForKey:#"text"];
NSLog(#"the given text:%#",items);
story = [NSMutableArray array];
title = [NSMutableArray array];
picture = [NSMutableArray array];
for (NSDictionary *item in items )
{
}

Answer 1

The problem is in this line:
items = [jsonArray objectForKey:#"text"];
As your code suggest it's an array not a dictionary thus you have grab the object from the array first:
for (NSDictionary *item in jsonArray ) {
NSDictionary *user = [item objectForKey:#"user"];
NSString *imageURLString = [user objectForKey:#"profile_image_url"];
}

Answer 2

NSData *data = [NSData dataWithContentsOfURL:jsonurl];
NSArray *array = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
if (!array) return;
NSDictionary *dictionary = [array objectAtIndex:0];
if (dictionary){
NSString *text = [dictionary valueForKey:#"text"];
NSString *profileBackgroundImageURL = [dictionary valueForKeyPath:#"user.profile_background_image_url"];
}

Answer 3

Use jsonlint.com to validate your JSON.
The error is lacking of the last closing operand } at the end of JSON string.
There're 2 opening but only one closing.
Parse error on line 52:
...cations": null }
----------------------^
Expecting '}', ',', ']'

Answer 4

Try this
items = [[jsonArray objectAtIndex:0] objectForKey:#"text"];
backImage=[[[jsonArray objectAtIndex:0] objectForKey:#"user"] objectForKey:#"profile_background_image_url"] ;
