如何设置谷歌地点的自动完成请求到iOS中的UITextField [英] How to set the google places Autocomplete Requests to a UITextField in iOS

问题描述

我是iOS编程新手。我的要求是将Google地方的自动填充请求设置为 UITextField 。
我写了下面的代码：

  NSString * urlPath = [NSString stringWithFormat：@/ maps / api / place /自动填充/ JSON输入=％@&安培;类型=地理编码及安培;语言= EN-EN&安培;传感器=假，串]; 
 NSURL * url = [[NSURL alloc] initWithScheme：@httphost：@maps.googleapis.compath：urlPath]; 
 NSLog（@url is :::％@，url）; 
 
 NSMutableURLRequest * request = [[NSMutableURLRequest alloc] init]; 
 [request setURL：url]; 
 [request setHTTPMethod：@POST]; 
 
 NSURLResponse *回应; 
 NSError *错误; 
 NSData *数据; 
 data = [NSURLConnection sendSynchronousRequest：request returningResponse：& response error：& error]; 
 NSLog（@data is :::％@，data）; 
 
 NSMutableDictionary * jsonDict =（NSMutableDictionary *）[NSJSONSerialization JSONObjectWithData：data options：kNilOptions error：& error]; 
 NSLog（@jsonDict is：％@，jsonDict）; 
  

但它是空的。你可以告诉我我在哪里做错了。 解决方案

U需要密钥才能申请Google Places API。
请参阅 SPGooglePlacesAutocomplete 链接，该链接符合您的要求。

编辑：请参阅文档。另请参阅如何注册Google地方信息

I am new to iOS programming. My requirement is to set the google places autocomplete request to a UITextField. I wrote the code as below

NSString *urlPath = [NSString stringWithFormat:@"/maps/api/place/autocomplete/json?input=%@&types=geocode&language=en-EN&sensor=false",string];
NSURL *url = [[NSURL alloc]initWithScheme:@"http" host:@"maps.googleapis.com" path:urlPath];
NSLog(@"url is:::%@",url);

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setURL:url];
[request setHTTPMethod:@"POST"];

NSURLResponse *response ;
NSError *error;
NSData *data;
data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"data is:::%@",data);

NSMutableDictionary *jsonDict= (NSMutableDictionary*)[NSJSONSerialization  JSONObjectWithData:data options:kNilOptions error:&error];
 NSLog(@"jsonDict is:%@",jsonDict);

But it gives empty. Can you tell me where I made wrong.

解决方案
