我對此很陌生。 我已經從網站解析10個值到一個tableview並鏈接到一個詳細視圖控制器。 如何在單擊每個單元格時顯示個別值?如何從NSDictionary中檢索值?

  • (無效)viewDidLoad中 {

    [[自的tableView] setDelegate:自]; [[self tableView] setDataSource:self]; array = [[NSMutableArray alloc] init];

    [array removeAllObjects];

    NSURL * url = [NSURL URLWithString:@「https://itunes.apple.com/us/rss/topalbums/limit=10/json」]; NSURLRequest * request = [NSURLRequest requestWithURL:url];

    connection = [NSURLConnection connectionWithRequest:request delegate:self];

    if(connection)webData = [[NSMutableData alloc] init]; }

- (無效)connectionDidFinishLoading:(NSURLConnection的*)連接{ 的NSDictionary * allDataDictionary = [NSJSONSerialization JSONObjectWithData:WEBDATA選項:0錯誤:無]; NSDictionary * feed = [allDataDictionary objectForKey:@「feed」]; NSArray * arrayOfEntry = [feed objectForKey:@「entry」];

for (NSDictionary *diction in arrayOfEntry){ 
    NSDictionary *title = [diction objectForKey:@"title"]; 
    NSString *label = [title objectForKey:@"label"]; 

    [array addObject:label]; 


} 
[[self tableView] reloadData]; 

}

你是什麼意思「從表中得到每個值」? – Wain

是否要打印關鍵字和值? –

你可以添加從webservice收到的json輸出到你的問題?這樣可以更容易地幫助你... – Jailbroken

JSON數據將是NSMutableArray格式。

NSMutableArray *allDataDictionary = [NSJSONSerialization JSONObjectWithData:webData options:0 error:nil]; 

int i=0; 
for (i=0;i<[allDataDictionary count];i++) { 
    NSLog("value is %@", [NSString stringWithFormat:@"%@", [[allDataDictionary objectAtIndex:i] objectForKey:@"yourKey"]];) 
}
