AFNetwork和GoogleAPI返回NULL

在對CLGeocoder非常失望之後，我決定改用GoogleMaps API。AFNetwork和GoogleAPI返回NULL

我已經設計了通話如下，使用AFNetwork：

AFHTTPClient *new = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://maps.googleapis.com/"]]; 

    NSDictionary *dict = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:@"thorsgade",@"true", nil] forKeys:[NSArray arrayWithObjects:@"address",@"sensor", nil]]; 
    NSMutableURLRequest *req = [new requestWithMethod:@"GET" path:@"maps/api/geocode/json" parameters:dict]; 

AFJSONRequestOperation *call = [AFJSONRequestOperation JSONRequestOperationWithRequest:req success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { 
      NSArray *geos = [JSON objectForKey:@"results"]; 
    DLog(@"Got result : '%@' %@ from %@ %@ %@",JSON,geos,[NSHTTPURLResponse localizedStringForStatusCode:response.statusCode],response.allHeaderFields,request.URL.description); 

     } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { 
      DLog(@"Failed %@ %@",error.localizedDescription,request.URL.description); 
     }]; 

[call start];

我得到這樣的反饋：

得到的結果：從沒有錯誤（空）（空）{ 「 Cache-Control「=」public，max-age = 86400「; 「內容編碼」= gzip; 「Content-Length」= 1603; 「Content-Type」=「application/json; charset = UTF-8」; 日期=「星期五，2012年12月07日08:51:58 GMT」; Expires =「Sat，08 Dec 2012 08:51:58 GMT」; Server = mafe; Vary =「Accept-Language」; 「X-Frame-Options」= SAMEORIGIN; 「X-XSS-Protection」=「1; mode = block」; } http://maps.googleapis.com/maps/api/geocode/json?sensor=true&address=thorsgade

無結果，但沒有錯誤。內容在標頭中被識別爲JSON，但原始的JSON爲空。

令人討厭的是，如果我在瀏覽器中打開http://maps.googleapis.com/maps/api/geocode/json?sensor=true&address=thorsgade，我會得到很多結果。

到目前爲止，我曾嘗試：

輕彈傳感器booleon真/假。
將用戶代理僞裝成常規Safari。
使用POST而不是GET。

，沒有運氣...

它的正常工作對我來說:)，你檢查哪個IOS版本？ – aahsanali

即時檢查6.0和6.0.1 –

如果問題仍然存在，我會建議使用MKNetworkKit代替

這裏是我的解決方案 -

GoogleGeocodeApi.h

//GoogleGeocodeApi.h 
#import <Foundation/Foundation.h> 
#import "MKNetworkEngine.h" 

typedef void (^JsonResponseBlock)(NSDictionary *); 
typedef void (^ErrorBlock)(NSError* error); 

@interface GoogleGeocodeApi : MKNetworkEngine 

-(MKNetworkOperation*) geocodeWithAddress: (NSString *) address 
          onCompletion:(JsonResponseBlock) completionBlock 
            onError:(ErrorBlock) errorBlock; 

@end

GoogleGeocode Api.m

//GoogleGeocodeApi.m 
#import "GoogleGeocodeApi.h" 

@implementation GoogleGeocodeApi 

-(id)init 
{ 
    if (self = [super initWithHostName:@"maps.googleapis.com" apiPath:@"maps/api/geocode" customHeaderFields:nil]) { 

    } 
    return self; 
} 

-(MKNetworkOperation*) geocodeWithAddress: (NSString *) address 
          onCompletion:(JsonResponseBlock) completionBlock 
            onError:(ErrorBlock) errorBlock; 
{ 
    MKNetworkOperation *op = [self operationWithPath:[NSString stringWithFormat:@"json?sensor=true&address=%@", address] params:nil httpMethod:@"GET"]; 
    [op onCompletion:^(MKNetworkOperation *completedOperation) { 
     NSDictionary *responseJSON = [completedOperation responseJSON]; 
     if (responseJSON && [[responseJSON objectForKey:@"status"] isEqualToString:@"OK"]) { 
      completionBlock(responseJSON); 
     } else { 
      NSDictionary* errorDictionary = @{NSLocalizedDescriptionKey :@"Google geocode failed!"}; 
      NSError *error = [NSError errorWithDomain:@"Failed response" code:100 userInfo:errorDictionary]; 
      errorBlock(error); 
     } 
    } onError:^(NSError* error) { 
     errorBlock(error); 
    }]; 

    [self enqueueOperation:op]; 

    return op; 
}

某處代碼

GoogleGeocodeApi *gma = [[GoogleGeocodeApi alloc] init]; 

    [gma geocodeWithAddress:@"thorsgade" 
       onCompletion:^(NSDictionary *responseJSON) { 
        NSLog(@"Geocode succeeded: %@", responseJSON); 
       } onError:^(NSError *error) { 
        NSLog(@"Geocode failed with error: %@", [error localizedDescription]); 
       }];
