如何在ios中使用json解析獲取數據

我是iPhone開發者的初學者。我想顯示從下面的源代碼我已經使用服務器數據..如何在ios中使用json解析獲取數據

-(void)loadData:(id)sender 
{ 
    self.requestdata=[NSMutableData data]; 
    NSURLRequest *request=[NSURLRequest requestWithURL:[NSURL URLWithString:kLatestKivaLoansURL]]; 
    [[NSURLConnection alloc]initWithRequest:request delegate:self]; 

    } 

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
{ 

    [requestdata setLength:0]; 
} 
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
{ 
    [requestdata appendData:data]; 

} 
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error 
{ 

    [connection release]; 
    self.requestdata=nil; 

} 

#pragma mark- 
#pragma process loan data 
- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 

    [connection release]; 
    NSString *responsedata=[[NSString alloc]initWithData:requestdata encoding:NSUTF8StringEncoding]; 
    self.requestdata=nil; 
    NSDictionary *respDict = [[responsedata JSONValue]objectForKey:@"nodes"]; 
    NSLog(@"Response Dict:%@",respDict); 
    NSMutableArray *arraY = [[NSMutableArray alloc]init]; 
    arraY = [respDict mutableCopy]; 
    NSLog(@"My array:%@",arraY); 
    NSString *mystr = [[[arraY objectAtIndex:0]valueForKey:@"node"]valueForKey:@"field_company_name_value"]; 
    NSLog(@"Mystrname:%@",mystr); 
    NSArray *latestLoans=[(NSDictionary *)[responsedata JSONValue]objectForKey:@"responseData"]; 
    NSLog(@"latest_dictionary:%@",latestLoans); 
    DisplayViewController *disp=[[DisplayViewController alloc]init]; 

    for (int i = 0; i< [[latestLoans valueForKey:@"entries"] count] ; i++) { 

     // Search *aSearches = [[Search alloc] init]; 

     NSDictionary *tempDict = [[latestLoans valueForKey:@"entries"] objectAtIndex:i]; 

     // disp.link=[tempDict valueForKey:@"link"]; 

     /*link = [tempDict valueForKey:@"link"]; 
     aSearches.title = [tempDict valueForKey:@"title"]; 
     aSearches.description = [tempDict valueForKey:@"contentSnippet"]; 
     [appDelegate.search addObject:aSearches];*/ 

     [appDelegate.disparray addObject:tempDict]; 
    } 

    NSLog(@"DisplayArray:%@",appDelegate.disparray); 
    [self.view addSubview:disp.view]; 
    /* DisplayViewController *disp=[[DisplayViewController alloc]initWithNibName:@"DisplayViewController" bundle:nil]; 
    [self.navigationController pushViewController:disp animated:YES];*/ 



}

請給任何建議或源代碼，這是適用於我的代碼

請問，你可以把更多的可讀代碼？ – RFG

首先向我們解釋它的功能。如果你不能解釋它，*你在做什麼使用它？* –

你對這個源代碼有什麼問題需要幫助？ –
