iOS - 使用 RestKit 进行 POST：未调用回调函数 - （使用映射数据）

Question

大家好，这是我在 stack-overflow 上的第一篇文章，

首先，非常感谢所有分享的人！

我的问题是：

• 当我使用 RKObjectManager 作为 POST 序列化对象时，我没有回调返回。
• 而且我不知道我对映射数据的使用是否正确...

所以我向您展示了我的 Restful 服务的结果（以 JSON 格式）、我的代码和我的 Restkit 日志

{"sessionId":"DA93D5ECD8E338AA27800794EEB9C20F","user":{"id":3,"ref":"2461498766","login":"clientTest","mail":"[email protected]","phone":"client127","subId":3,"creation":"29/03/2010 10:33:24","language":"en","firstConnection":"30/03/2010 16:42:07","lastConnection":"02/11/2011 09:36:43","connectionStep":"6"},"gateway":{"id":3,"serial":"testserial","status":"A","led":"START","ref":"DJJHGGGG00009","type":"FULL","ip":"192.168.44.168","connection":"","initDate":1290694795533,"activationDate":1290694795533,"manufacDate":1269851384000,"imei":"354482020013035","model":"TYLOP","firmware":"1.3.1","version":"","macWifi":"...","macEthernet":"...","updateDate":1310053274000,"muteMode":"","timezone":""}}

如您所见，我们有一个全局对象里面：用户，网关对象。

VOAuth.h，我用于数据映射的全局对象：

#import "VOUser.h"
#import "VOGateway.h"

@interface VOAuth : NSObject
@property (nonatomic, retain) NSString * sessionId;
@property (nonatomic, retain) VOUser * user;
@property (nonatomic, retain) VOGateway * gateway;
@end

VOGateway.h，

#import <Foundation/Foundation.h>

@interface VOGateway : NSObject

@property (nonatomic, retain) NSString * identifier;
@property (nonatomic, retain) NSString * serial;
@property (nonatomic, retain) NSString * status;
@property (nonatomic, retain) NSString * led;
@property (nonatomic, retain) NSString * ref;
@property (nonatomic, retain) NSString * type;
@property (nonatomic, retain) NSString * ip;
@property (nonatomic, retain) NSString * connection;
@property (nonatomic, retain) NSString * initDate;
@property (nonatomic, retain) NSString * activationDate;
@property (nonatomic, retain) NSString * manufacDate;
@property (nonatomic, retain) NSString * imei;
@property (nonatomic, retain) NSString * model;
@property (nonatomic, retain) NSString * firmware;
@property (nonatomic, retain) NSString * version;
@property (nonatomic, retain) NSString * macWifi;
@property (nonatomic, retain) NSString * macEthernet;
@property (nonatomic, retain) NSString * updateDate;
@property (nonatomic, retain) NSString * muteMode;
@property (nonatomic, retain) NSString * timezone;

@end

VOUser.h，

#import <Foundation/Foundation.h>

@interface VOUser : NSObject

@property (nonatomic, retain) NSString * identifier;
@property (nonatomic, retain) NSString * ref;
@property (nonatomic, retain) NSString * login;
@property (nonatomic, retain) NSString * mail;
@property (nonatomic, retain) NSString * phone;
@property (nonatomic, retain) NSString * subId;
@property (nonatomic, retain) NSString * creation;
@property (nonatomic, retain) NSString * language;
@property (nonatomic, retain) NSString * firstConnection;
@property (nonatomic, retain) NSString * lastConnection;
@property (nonatomic, retain) NSString * connectionStep;

@end

SOAuth.h（我的序列化对象用作我的调用参数），

#import <Foundation/Foundation.h>

@interface SOAuth : NSObject
@property (nonatomic, retain) NSString* login;
@property (nonatomic, retain) NSString* password;
@end

MAModule.h（我的经理，我在这里调用我的restfull服务），

#import <Foundation/Foundation.h>
#import <RestKit/RestKit.h>
#import "VOUser.h"
#import "VOGateway.h"
#import "VOAuth.h"
#import "SOAuth.h"
@interface MAModule : NSObject <RKObjectLoaderDelegate>
-(void)sendLogIn;
- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects;
- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error;
@end

MAModule.m，

#import "MAModule.h"

@implementation MAModule

-(void)sendLogIn
{

RKLogConfigureByName("RestKit/Network", RKLogLevelTrace);

RKObjectManager* manager = [RKObjectManager    objectManagerWithBaseURL:@"http://mydomain.dev/ui/v1"];
[RKObjectManager sharedManager].serializationMIMEType = RKMIMETypeJSON;
[manager.router routeClass:[SOAuth class] toResourcePath:@"/auth" forMethod:RKRequestMethodPOST];

RKObjectMapping* authSerializationMapping = [RKObjectMapping mappingForClass:[NSMutableDictionary class] ];
[authSerializationMapping mapAttributes:@"login", @"password", nil];
[[RKObjectManager sharedManager].mappingProvider setSerializationMapping:authSerializationMapping forClass:[SOAuth class] ];

RKObjectMapping *userMapping = [RKObjectMapping mappingForClass:[VOUser class]];
[userMapping mapKeyPath:@"id" toAttribute:@"identifier"];
[userMapping mapKeyPath:@"ref" toAttribute:@"ref"];
[userMapping mapKeyPath:@"login" toAttribute:@"login"];
[userMapping mapKeyPath:@"mail" toAttribute:@"mail"];
[userMapping mapKeyPath:@"phone" toAttribute:@"phone"];
[userMapping mapKeyPath:@"subId" toAttribute:@"subId"];
[userMapping mapKeyPath:@"creation" toAttribute:@"creation"];
[userMapping mapKeyPath:@"language" toAttribute:@"language"];
[userMapping mapKeyPath:@"firstConnection" toAttribute:@"firstConnection"];
[userMapping mapKeyPath:@"lastConnection" toAttribute:@"lastConnection"];
[userMapping mapKeyPath:@"connectionStep" toAttribute:@"connectionStep"];


RKObjectMapping *gatewayMapping = [RKObjectMapping mappingForClass:[VOGateway class]];
[gatewayMapping mapKeyPath:@"id" toAttribute:@"identifier"];
[gatewayMapping mapKeyPath:@"serial" toAttribute:@"serial"];
[gatewayMapping mapKeyPath:@"status" toAttribute:@"status"];
[gatewayMapping mapKeyPath:@"led" toAttribute:@"led"];
[gatewayMapping mapKeyPath:@"ref" toAttribute:@"ref"];
[gatewayMapping mapKeyPath:@"type" toAttribute:@"type"];
[gatewayMapping mapKeyPath:@"ip" toAttribute:@"ip"];
[gatewayMapping mapKeyPath:@"connection" toAttribute:@"connection"];
[gatewayMapping mapKeyPath:@"initDate" toAttribute:@"initDate"];
[gatewayMapping mapKeyPath:@"activationDate" toAttribute:@"activationDate"];
[gatewayMapping mapKeyPath:@"manufacDate" toAttribute:@"manufacDate"];
[gatewayMapping mapKeyPath:@"imei" toAttribute:@"imei"];
[gatewayMapping mapKeyPath:@"model" toAttribute:@"model"];
[gatewayMapping mapKeyPath:@"firmware" toAttribute:@"firmware"];
[gatewayMapping mapKeyPath:@"version" toAttribute:@"version"];
[gatewayMapping mapKeyPath:@"macWifi" toAttribute:@"macWifi"];
[gatewayMapping mapKeyPath:@"macEthernet" toAttribute:@"macEthernet"];
[gatewayMapping mapKeyPath:@"updateDate" toAttribute:@"updateDate"];
[gatewayMapping mapKeyPath:@"muteMode" toAttribute:@"muteMode"];
[gatewayMapping mapKeyPath:@"timezone" toAttribute:@"timezone"];

RKObjectMapping *authReturnMapping = [RKObjectMapping mappingForClass:[VOAuth class]];
[authReturnMapping mapKeyPath:@"sessionId" toAttribute:@"sessionId"];
[authReturnMapping mapKeyPath:@"user" toRelationship:@"user" withMapping:userMapping];
[authReturnMapping mapKeyPath:@"gateway" toRelationship:@"gateway" withMapping:gatewayMapping];
[[RKObjectManager sharedManager].mappingProvider setMapping:authReturnMapping forKeyPath:@""];
[[RKObjectManager sharedManager].mappingProvider setSerializationMapping:[authReturnMapping inverseMapping] forClass:[VOAuth class]]; 

NSLog(@"LOGIN SEND --------------------------------");    
SOAuth *logObj = [[SOAuth alloc]init];
logObj.login = @"clientTest";
logObj.password = @"216a2e1269b5daaa35fd911964e5a86ce11f267d";

RKObjectMapping* authhMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[VOAuth class] ];
[[RKObjectManager sharedManager] postObject:logObj mapResponseWith:authhMapping delegate:nil];
}

- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects {
//RKLogInfo(@"Load collection of Articles: %@", objects);
NSLog(@"LOGIN OK --------------------------------");
}

- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error {
NSLog(@"LOGIN KO --------------------------------");
}

@end

我想强调几点：

• [[RKObjectManager sharedManager].mappingProvider setMapping:authReturnMapping forKeyPath:@""] ：我有我的全局对象映射的空键，因为我没有它的根键...

• [[RKObjectManager shareManager] postObject:logObj mapResponseWith:authhMapping delegate:nil];我的委托为零，否则我的应用程序崩溃...

最后，

我的回调函数没有被调用：

• (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects

• (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error

希望有人可以帮助我，

TY。

您的方法不会被调用，因为您将 nil 设置为您的委托。根据我们后面的讨论，如果 self 作为委托传递，则随后的崩溃是由于 MAModule 过早释放而导致的。使用属性或单例模式保留 MAModule 对象至少直到您的请求完成。
