從Restkit獲取錯誤說明

Question

當我的Web服務返回錯誤時，我想顯示返回響應的錯誤消息。我找不到在RestKit中執行此操作的任何方法。我試過設置對象管理器的錯誤映射屬性，使用以下建議：

Restkit json error response msg from server

但是，這並不爲我工作。首先，RKErrorMessage似乎不再存在。

任何幫助表示讚賞。

Answer 1

在第20節，你必須做兩件事情：

首先，導入RKErrorMessage.h文件：

#import <RestKit/RKErrorMessage.h>

然後，添加錯誤映射到你的ObjectManager ：

RKObjectMapping *errorMapping = [RKObjectMapping mappingForClass:[RKErrorMessage class]]; 
    [errorMapping addPropertyMapping:[RKAttributeMapping attributeMappingFromKeyPath:@"error" toKeyPath:@"errorMessage"]]; 
    [objectManager addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:errorMapping pathPattern:nil keyPath:@"error" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassClientError)]]; 

Answer 2

試試這一個RestKit〜> 0.22.0

// Setup error mapping 
RKObjectMapping *errorMapping = [RKObjectMapping mappingForClass:[RKErrorMessage class]]; 
[errorMapping addPropertyMapping: [RKAttributeMapping attributeMappingFromKeyPath:@"errorDescription" toKeyPath:@"errorMessage"]]; 
RKResponseDescriptor *errorResponseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:errorMapping 
                          method:RKRequestMethodAny 
                         pathPattern:nil 
                          keyPath:nil 
                         statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassClientError)]; 
[[RKObjectManager sharedManager] addResponseDescriptor:errorResponseDescriptor];
