第一次寫你的代碼...然後我建議你。 – 2012-12-11 09:56:13

檢查我的答案http://stackoverflow.com/questions/12580407/i-have-json-data-given-below-and-i-want-to-display-it-in-a-table/12580451#12580451 – Rajneesh071

看起來你的價值觀已經被提取出來了，否則你怎麼能發佈它們......？ – holex

NSString *responseString = [request1 responseString];//your json response will be here 
NSMutableDictinoary *dataDict = [[[responseString JSONValue] valueForKey:@"DAATA"]mutableCopy];//take response in dictinoary 
for(int i = 0 ; i<[[dataDict valueForKey:@"DAATA"] count];i++) 
{ 
    if([[[[dataDict valueForKey:@"DAATA"] objectAtIndex:i] valueForKey:@"Image_Id"] isEqualToString:@"court"])//get what you want here for example get "Image_Id" 
    { 
     NSMutableDictionary *dd=[[dataDict valueForKey:@"result"] objectAtIndex:i]; 
     [arrCourt addObject:dd]; 
    } 
    and so on......... 

}

謝謝，我已經做了那個時間.... –

檢出NSJSONSerialization並用它來解析你的json字符串。

另一種選擇是使用SBJson庫。

- (void) connectionDidFinishLoading:(NSURLConnection *) conn 
{ 
//Call back called when data reception completes (stored in variable data) 
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
NSDictionary *results = [jsonString JSONValue]; // This is a new category added to the NSString by SBJSON 
if ([results count]>0) 
{ 
    // decoding a JSON object like so: {"result":"yes"} 
    [results objectForKey:@"result"] ; 
    if ([[results objectForKey:@"result"] isEqualToString:@"yes"]) 
    { 
     [self registrationStateSetTo:YES]; 
     NSLog(@" registered OK "); 
    } 
    else 
    { 
     [self registrationStateSetTo:NO]; 
     NSLog(@" registration failed "); 
    } 
} 
}
