Iphone 试图解析推特趋势

我试图解析twitter趋势，但我一直在“as_of”处遇到一个解析错误。有人知道为什么会这样吗

编辑：

这是我使用的代码

NSMutableArray *tweets;
tweets = [[NSMutableArray alloc] init];
NSURL *url = [NSURL URLWithString:@"http://search.twitter.com/trends/current.json"];
trendsArray = [[NSMutableArray alloc] initWithArray:[CCJSONParser objectFromJSON:[NSString stringWithContentsOfURL:url encoding:4 error:nil]]]; 

NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];

for (int i = 0; i < [trendsArray count]; i++) {
    dict = [[NSMutableDictionary alloc] init];
    //[post setObject: [[currentArray objectAtIndex:i] objectForKey:@"query"]];
    [dict setObject:[trendsArray objectAtIndex:i] forKey:@"trends"];
    //[dict setObject:[trendsArray objectAtIndex:i] forKey:@"query"];
    //[post setObject:[trendsArray objectAtIndex:i] forKey:@"as_of"];
    [tweets addObject:dict];
    //post = nil;
}

NSMutableArray*推文；
tweets=[[NSMutableArray alloc]init]；
NSURL*url=[NSURL URLWithString:@”http://search.twitter.com/trends/current.json"];
trendsArray=[[NSMutableArray alloc]initWithArray:[CCJSONParser objectFromJSON:[NSString stringWithContentsOfURL:url编码：4错误：无]]；
NSMutableDictionary*dict=[[NSMutableDictionary alloc]init]；
对于（int i=0；i<[trendsArray计数]；i++）{
dict=[[NSMutableDictionary alloc]init]；
//[post setObject:[[currentArray objectAtIndex:i]objectForKey:@“查询”]；
[dict setObject:[trendsArray objectAtIndex:i]forKey:@“趋势”]；
//[dict setObject:[trendsArray objectAtIndex:i]forKey:@“查询”]；
//[post-setObject:[trendsArray-objectAtIndex:i]forKey:@“as_of”]；
[tweets addObject:dict]；
//post=零；
}

我不太确定您的问题可能是什么，但我已经尝试过twitter api和CCJSON，并获得了一些似乎有效的示例代码。如果您将其剪切并粘贴到新项目的

applicationdFinishLaunching

方法中，并包含CCJSON文件，它将正常工作（希望如此）

这段代码将从twitter获取趋势json，输出值的as_并创建一个趋势数组

// Make an array to hold our trends
NSMutableArray *trends = [[NSMutableArray alloc] initWithCapacity:10];

// Get the response from the server and parse the json
NSURL *url = [NSURL URLWithString:@"http://search.twitter.com/trends/current.json"];
NSString *responseString = [NSString stringWithContentsOfURL:url encoding:4 error:nil];
NSDictionary *trendsObject = (NSDictionary *)[CCJSONParser objectFromJSON:responseString]; 

// Output the as_of value
NSLog(@"%@", [trendsObject objectForKey:@"as_of"]);

// We also have a list of trends (by date it seems, looking at the json)
NSDictionary *trendsList = [trendsObject objectForKey:@"trends"];

// For each date in this list
for (id key in trendsList) {
    // Get the trends on this date
    NSDictionary *trendsForDate = [trendsList objectForKey:key];

    // For each trend in this date, add it to the trends array
    for (NSDictionary *trendObject in trendsForDate) {
        NSString *name = [trendObject objectForKey:@"name"];
        NSString *query = [trendObject objectForKey:@"query"]; 
        [trends addObject:[NSArray arrayWithObjects:name, query, nil]];
    }
}

// At the point, we have an array called 'trends' which contains all the trends and their queries.
// Lets see it . . .
for (NSArray *array in trends)
    NSLog(@"name: '%@' query: '%@'", [array objectAtIndex:0], [array objectAtIndex:1]);

希望这是有用的，如果您有任何问题，请发表评论

PS我曾经可视化JSON响应-这使查看发生了什么变得更容易-我只是将JSON从中剪切并粘贴到其中：）

你能发布一些示例代码和数据吗？你只是在使用吗？您使用的JSON解析库/框架是什么？发布您正在使用的代码。我正在使用CCJSON解析上面发布的代码。您可以发布一些示例代码和数据吗？您正在使用吗？您使用的JSON解析库/框架是什么？发布您正在使用的代码。我正在使用CCJSON解析上面发布的代码
