没有得到JSON响应谷歌查询经度和纬度在iOS？ [英] Not getting json response in google query of longitude and latitude in iOS?

问题描述

我是iOS新手，所以如果有任何帮助，将不胜感激。
我想从地址中获取经度和纬度，之前的代码工作正常，但现在JSON数据将变为空。

这里我的示例代码，

  url = [NSString stringWithFormat：@http://maps.google.com/maps/api/geocode/json ？地址=％@&安培;传感器=假，appDelegate.sAddress]; 
 
 url = [url stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding]; 
 NSLog（@地址URL：％@，url）; 
 
 //将字符串表示为URL对象。 
 NSURL * requestURL = [NSURL URLWithString：url]; 
 NSData * data = [NSData dataWithContentsOfURL：requestURL]; 
 
 NSString * returnString = [[NSString alloc] initWithData：data encoding：NSUTF8StringEncoding]; 
 
 NSLog（@my Coordinate：％@，returnString）; 
 
 NSError *错误; 
 NSDictionary * json = [NSJSONSerialization 
 JSONObjectWithData：data 
 options：kNilOptions 
 error：& error]; 
  

但是我得到的输出为空。

>感谢你的回复，所有这些让我学到了很多东西。
作为我的朋友之一，告诉我解决方案，以便我与您分享。

以下是代码，

  url = [NSString stringWithFormat：@http://maps.google.com/maps/api/geocode/json?address=%@&sensor=false  appDelegate.sAddress]; 
 
 url = [url stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding]; 
 NSLog（@地址URL：％@，url）; 
 
 //将字符串表示为URL对象。 
 NSURL * requestURL = [NSURL URLWithString：url]; 
 NSData * data = [NSData dataWithContentsOfURL：requestURL]; 
 
 NSString * returnString = [[NSString alloc] initWithData：data encoding：NSUTF8StringEncoding]; 
 
 SBJSON * parser = [[SBJSON alloc] init]; 
 NSDictionary * locationResult = [解析器objectWithString：returnString]; 
 // [reverseGeoString copy]`
  

其工作正常。

但仍然存在一个问题，为什么会发生这种情况。早些时候，代码工作正常，但它突然停止工作。

I am new to iOS, so if any help it will be appreciated. I am trying to get the longitude and latitude from address, earlier the code was working fine but now the JSON data are coming null.

Here my sample code,

     url = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?address=%@&sensor=false",appDelegate.sAddress];

    url=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSLog(@"Address URL: %@",url);

    //Formulate the string as a URL object.
    NSURL *requestURL=[NSURL URLWithString:url];
    NSData* data = [NSData dataWithContentsOfURL: requestURL];

    NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

    NSLog(@"my Coordinate : %@",returnString);

    NSError* error;
    NSDictionary* json = [NSJSONSerialization 
                          JSONObjectWithData:data
                          options:kNilOptions 
                          error:&error];

But i am getting the output as null.

So please help me out.

Thanks!

解决方案

Thanks for your replies that all make me learn a lots. As one of my friend just tell me the solution so i am sharing with you.

Here is the code,

url = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?address=%@&sensor=false",appDelegate.sAddress];

url=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(@"Address URL: %@",url);

//Formulate the string as a URL object.
NSURL *requestURL=[NSURL URLWithString:url];
NSData* data = [NSData dataWithContentsOfURL: requestURL];

NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

SBJSON *parser = [[SBJSON alloc] init];
NSDictionary *locationResult = [parser objectWithString:returnString];
//[reverseGeoString copy]`

And its working fine.

But still there is a question that why this happen.As earlier that code is working fine but it suddenly stopped working.
