我是 iOS 开发的新手。我想使用 RestKit 访问 Web 服务并将数据映射到我的自定义对象。
我确定正在达到搜索方法。但是，没有触发任何回调方法（didLoadObjects 或 didFailWithError）。我的代码如下。谢谢你的帮助！
编辑：我尝试用一个简单的 RKClient 请求做同样的事情，这些回调方法也没有被触发。我还实现了“观察请求进度”方法，这些方法也没有被触发。我没有正确分配代表吗？
编辑 2：看起来请求可能被卡在队列中。如果我强制它异步发送，则会触发“requestWillPrepareForSend”和“requestDidStartLoad”方法。不会触发其他方法。
- (void)search{
NSString *baseURL = @"sws.acpl.lib.in.us:8080/symws/rest/";
NSURL *url=[NSURL URLWithString:baseURL];
RKObjectManager *manager=[RKObjectManager objectManagerWithBaseURL:url];
RKObjectMapping *availabilityMapping = [RKObjectMapping mappingForClass:[TitleAvailabilityInfo class]];
[availabilityMapping mapAttributes:@"totalAvailableCopies", @"holdable", nil];
RKObjectMapping *titleMapping = [RKObjectMapping mappingForClass:[SearchResultsTitle class]];
[titleMapping mapAttributes:@"titleID",@"title",@"author",@"materialType",@"yearOfPublication",@"ISBN",@"callNumber", nil];
[titleMapping mapKeyPath:@"TitleAvailabilityInfo" toRelationship:@"titleAvailabilityInfo" withMapping:availabilityMapping];
RKObjectMapping *searchResponseMapping = [RKObjectMapping mappingForClass:[SearchCatalogResponse class]];
[searchResponseMapping mapAttributes:@"queryID",@"totalHits",@"firstHitDisplayed",@"lastHitDisplayed", nil];
[searchResponseMapping mapKeyPath:@"HitlistTitleInfo" toRelationship:@"results" withMapping:titleMapping];
[manager.mappingProvider setMapping:searchResponseMapping forKeyPath:@"SearchCatalogResponse"];
[manager loadObjectsAtResourcePath:@"standard/searchCatalog" delegate:self];
}
