以下是我用来解析的ios代码

 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 )
{


}

问题出在这一行：

items = [jsonArray objectForKey:@"text"];

正如您的代码所暗示的，它是一个数组而不是字典，因此您首先从数组中获取对象：

for (NSDictionary *item in jsonArray ) {
     NSDictionary *user = [item objectForKey:@"user"];  
     NSString *imageURLString = [user objectForKey:@"profile_image_url"];


}

    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"];
    }

使用jsonlint.com验证您的 JSON。错误是缺少 JSON 字符串末尾的最后一个关闭操作数 }。有2个开场，但只有1个关门。

Parse error on line 52:
...cations": null    }

试试这个

items = [[jsonArray objectAtIndex:0] objectForKey:@"text"];

backImage=[[[jsonArray objectAtIndex:0] objectForKey:@"user"] objectForKey:@"profile_background_image_url"] ;
