IOS RESTKIT HTTP PUT示例

Question

我想更新在REST API中運行的服務器中的數據。我使用ios設備的RESTKIT。但我找不到如何在restkit中使用PUT。

我必須發送如key：「user_id」的數據值：「2」這些格式。任何人都可以請幫我解決這個問題.. :(

SOKeyValue.h：作爲參數，你的電話，序列化對象

#import <Foundation/Foundation.h> 

@interface SOKeyValue : NSObject 
@property (nonatomic, retain) NSString* key; 
@property (nonatomic, retain) NSString* value; 
@end 

這裏有一個簡單的代碼來初始化Restkit：

/* 
This part of code must be executed only one time in your application 
*/ 
//To see logs 
RKLogConfigureByName("RestKit/Network", RKLogLevelTrace); 

//Init with good domain 
RKObjectManager* manager = [RKObjectManager objectManagerWithBaseURL:@"http://mydomain.dev/ui/v1"]; 

//Indicate to use JSON 
[RKObjectManager sharedManager].serializationMIMEType = RKMIMETypeJSON; 

//Route path when you call a PUT with SOKeyValue class 
[manager.router routeClass:[SOKeyValue class] toResourcePath:@"/yourpath" forMethod:RKRequestMethodPUT]; 

//Serialization for SOKeyValue class 
RKObjectMapping* keyvalueSerializationMapping = [RKObjectMapping mappingForClass:[NSMutableDictionary class] ]; 
[authSerializationMapping mapAttributes:@"key", @"value", nil]; 
[[RKObjectManager sharedManager].mappingProvider setSerializationMapping:keyvalueSerializationMapping forClass:[SOKeyValue class] ]; 

現在我們可以實現一個使用PUT的服務，在實現該調用的對象中不要忘記restkit委託RKObjectLoaderDelegate：

#import <Foundation/Foundation.h> 
#import <RestKit/RestKit.h> 
#import "SOKeyValue.h" 
@interface MyViewOrMyServiceObject: NSObject <RKObjectLoaderDelegate> 
- (void)putKeyValue; 
- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects; 
- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error; 
@end 

在你（.M）：

- (void)putKeyValue 
{ 

    SOKeyValue *keyvalue = [[SOKeyValue alloc] init]; 
    keyvalue.key = @"k"; 
    keyvalue.value = @"2"; 
    [[RKObjectManager sharedManager] putObject:keyvalue delegate:self]; 
    [keyvalue release]; 
} 

你可以看到你的跟蹤狀態代碼，並使用回調函數：

- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects; 
- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error; 

所以我沒有MAC在家裏，這是艱難的齧合以幫助您瞭解代碼結構。如果你有問題，請不要猶豫。
