如何从此JSON响应中获取电话号码？

Question

一个小幽默：。书呆子总是有问题让电话号码:(

我试图得到电话号码从这个谷歌Places API的响应，在iOS上开发应用

    "html_attributions" : [], 
    "result" : { 
    "address_components" : [ 
     { 
     "long_name" : "48", 
     "short_name" : "48",

     }, 
     { 
     "long_name" : "Pirrama Road", 
     "short_name" : "Pirrama Road", 
     "types" : [ "route" ] 
     }, 
     { 
     "long_name" : "Pyrmont",

目标： “international_phone_number”： “+61 2 9374 4000”

我迄今为止的努力，

NSDictionary *results = [responseString JSONValue]; 
    placeInfo = [results objectForKey:@"result"]; 
//Getting result details but than I am stuck how to get to that international phone number? 

任何输入将不胜感激！谢谢

Answer 1

尝试：

NSString *phoneNumber = [placeInfo objectForKey:@"formatted_phone_number"]; 
NSLog(@"Her Phone Number: %@", phoneNumber); 

Answer 2

你有上述转储布局的结构。最外层的结构是一个字典，一些字典条目包含数组，一些包含其他字典。 （{}表示字典，[]表示数组）。

因此，您可以看到“结果”会生成另一个字典。该字典的一个元素是“formatted_phone_number”。它包含一个字符串形式的电话号码。

剥离洋葱的层。

Answer 3

placeInfo = [results objectForKey:@"result"]; 
NSString *internationalPhone = [placeInfo objectForKey:@"international_phone_number"]; 

试试这个，看看，当你这样做的NSLog出现的电话号码（@ “电话：％@”，internationalPhone）

Answer 4

NSError *parseError = nil; 

// Your test json as NSString 
NSString * json = @"{ \"html_attributions\" : [], \"result\" : { \"address_components\" : [ { \"long_name\" : \"48\", \"short_name\" : \"48\", \"types\" : [ \"street_number\" ] }, { \"long_name\" : \"Pirrama Road\", \"short_name\" : \"Pirrama Road\", \"types\" : [ \"route\" ] }, { \"long_name\" : \"Pyrmont\", \"short_name\" : \"Pyrmont\", \"types\" : [ \"locality\", \"political\" ] }, { \"long_name\" : \"NSW\", \"short_name\" : \"NSW\", \"types\" : [ \"administrative_area_level_1\", \"political\" ] }, { \"long_name\" : \"AU\", \"short_name\" : \"AU\", \"types\" : [ \"country\", \"political\" ] }, { \"long_name\" : \"2009\", \"short_name\" : \"2009\", \"types\" : [ \"postal_code\" ] } ], \"formatted_address\" : \"5/48 Pirrama Road, Pyrmont NSW, Australia\", \"formatted_phone_number\" : \"(02) 9374 4000\", \"geometry\" : { \"location\" : { \"lat\" : -33.8669710, \"lng\" : 151.1958750 } }, \"icon\" : \"http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png\", \"id\" : \"4f89212bf76dde31f092cfc14d7506555d85b5c7\", \"international_phone_number\" : \"+61 2 9374 4000\", \"name\" : \"Google Sydney\", \"rating\" : 4.60, \"reference\" : \"CnRlAAAAAfV6JIqSzL8Cf4VnXn0EaI1d5k3IPhdkEonq0MxiUbQFFSVuptVbXbNH4mrevb0bc7G8yWqTUv76i4KTuO_Wf3OrRHjCJJwzQ0mNLjbYGSVqy2eqyrgOUkl6S_sJfTbHzWZYrfPy7KZaet0mM5S6thIQJYuy5v_JD--ZxXEJLWTQRRoU5UaciXBBo89K-bce18Ii9RsEIws\", \"types\" : [ \"store\", \"establishment\" ], \"url\" : \"http://maps.google.com/maps/place?cid=10281119596374313554\", \"vicinity\" : \"5/48 Pirrama Road, Pyrmont\", \"website\" : \"http://www.google.com.au/\" }, \"status\" : \"OK\" }"; 

// Converting to data and stripping last 0x0 byte 
NSData* aweData = [json dataUsingEncoding:NSUTF8StringEncoding]; 
[aweData subdataWithRange:NSMakeRange(0, [aweData length] - 1)]; 

id jsonObject = [NSJSONSerialization JSONObjectWithData:aweData options:NSJSONReadingAllowFragments error:&parseError]; 

NSString* result = [[jsonObject objectForKey:@"result"] objectForKey:@"international_phone_number"]; // +61 2 9374 4000 

Answer 5

你也可以避免通过使用创建额外变量

NSString* phoneNumber = [results objectForKeyPath@"result.international_phone_number"];
