如何整合Google將API放入我們的應用程序？

Question

IAM發展，我想使用谷歌的地方之一application.In api.I寫的網址，並建立類似

連接

NSURL *URL = [NSURL URLWithString:@"https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=true&key=AIzaSyDbiWWIOmc08YSb9DAkdyTWXh_PirVuXpM"]; 
NSURLRequest *request=[[NSURLRequest alloc]initWithURL:URL]; 
[[NSURLConnection alloc] initWithRequest:request delegate:self]; 

But in did finish loading delegate method i cant get the data.That code is here. 
- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
[connection release]; 
NSString *responseString = [[NSString alloc]initWithData:responseDataencoding:NSUTF8StringEncoding]; 
    [responseData release]; 
    SBJSON *parser = [[SBJSON alloc]init]; 
    NSDictionary *data = (NSDictionary *) [parser objectWithString:responseString error:nil]; 

} 

所以，請告訴我，我做了mistake.Why IAM沒有得到數據。

Answer 1

使用ASIHTTPRequest framwork所有這些問題都自動處理

所有你所要做的僅僅是創建一個URL 和分析使用JSON響應框架

Answer 2

據我所知，有幾個mistaks。

1. NSString *responseString = [[NSString alloc]initWithData:responseDataencoding:NSUTF8StringEncoding];

的話responseData編碼是兩個世界。我不知道你是否粘貼過這種東西。

1. 我希望您已使用-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data委託人將數據追加到responseData對象。

2. 我認爲你不需要轉換成NSDictionary。您可以使用以下代碼。

   NSString *content = [[NSString alloc] initWithBytes:[responseDate bytes] length:[responseDate length] encoding:NSUTF8StringEncoding]; NSLog(@"Data = %@", content); NSError *error; SBJsonParser *parser = [[SBJsonParser alloc] init]; NSDictionary *jsonD = [parser objectWithString:content error:&error];
