Question

我想知道是否有关于如何使用RESTKit执行POST请求的特定教程。我看过一些教程，但我没有发现任何说法，“这正是你用RESTKit做POST命令的方式。”非常感谢帮助。

假设您已经有一个映射模型，您可以简单地执行此操作：

首先，设置一个requestDescriptor，使用responseDescriptor的inverseMapping，假设你有一个映射。

//This is used for mapping responses, you already should have one of this. PS:[Data mapping] is a method that returns an RKObjectMapping for my model. You should create yours or use a previous created one
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[Data mapping] pathPattern:nil keyPath:@"data" statusCodes:statusCodeSet];
[[RKObjectManager sharedInstance] addResponseDescriptor:responseDescriptor];

//Inverse mapping, to perform a POST
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[[Data mapping] inverseMapping]  objectClass:[Data class] rootKeyPath:nil];
[[RKObjectManager sharedInstance] addRequestDescriptor:requestDescriptor];

之后，要执行POST，只需调用以下方法即可。 Restkit将获取您要发布的实例，将其序列化并发送到所选路径。

[[RKObjectManager sharedInstance] postObject:instanceOfYourModel path:yourPathHere parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    NSLog(@"Success");

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"Error");
}];

如果您没有映射模型，请告诉我们，我们可以尝试其他方法。
