我在线上关注Tutorial,我有2种向Google Places API提交查询的方法。我试图得到一个回应不幸的是,它不工作。我在代码中有一些调试号码。但是,这是代码。Google Places API未返回响应
-(void) queryGooglePlaces{
NSString *url = @"https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=myKey";
//Formulate the string as a URL object.
NSURL *googleRequestURL=[NSURL URLWithString:url];
NSLog(@"1.5");
// Retrieve the results of the URL.
dispatch_async(kBgQueue, ^{
NSData* data = [NSData dataWithContentsOfURL: googleRequestURL];
[self performSelectorOnMainThread:@selector(fetchedData:) withObject:data waitUntilDone:YES];
});
NSLog(@"2");
}
-(void)fetchedData:(NSData *)responseData {
//parse out the json data
NSError* error;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseData
options:kNilOptions
error:&error];
//The results from Google will be an array obtained from the NSDictionary object with the key "results".
NSArray* places = [json objectForKey:@"results"];
//Write out the data to the console.
NSLog(@"Google Data: %@", places);
NSLog(@"3");
}
在日志输出变为这样:

谁能告诉我怎么回事错了,所以我没没有得到回应? 是的,我在ViewDidLoad
方法[self queryGooglePlaces];
方法 欣赏帮助家伙!对不起,如果我太冗长了......刚开始尝试学习!
以及我的网址是不同的 然而,这个特殊的网址,我直接从Google Places API网站拉出来,并简单地更换了我的API密钥。 所以你认为问题只在于网址? – 2012-08-06 18:59:37
确切的URL与您的问题无关。我正在专门讲述如何在将URL发送到服务器进行处理之前对其进行编码。 – 2012-08-06 19:19:38
即使当我添加该行代码 我没有得到回应:( – 2012-08-06 19:43:04
