如何将 RKObjectManager 的委托设置为 nil? [英] How do I set RKObjectManager's delegate to nil?

问题描述

我想将 RKObjectManager 的委托设置为 nil.但是我找不到委托属性.

I want to set RKObjectManager's delegate to nil. But I can't find delegate property.

我的要求是:

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"getData" 
  objectMapping:[[RKObjectManager sharedManager].mappingProvider 
                      objectMappingForKeyPath:@"clips"] delegate:self];

更新:我的应用程序崩溃了.我转到剪辑"并在 viewDidLoad 中发送 loadObjectsAtResourcePath.如果我迅速离开这个屏幕，我会在 [RKResponse connection:didReceiveData:] 处崩溃.

UPDATE: There is a crash in my app. I go to "Clips" and in the viewDidLoad send loadObjectsAtResourcePath. If I rapidly leave this screen I get crash at [RKResponse connection:didReceiveData:].

推荐答案

崩溃是由于您的委托"对象被释放.您的问题有一个简单的解决方案 - 只需取消所有待处理的请求，例如.在您的 viewDidUnload(或 dealloc，这取决于您的实现)方法中.

The crash is caused by your 'delegate' object being dealloc'd. There is a simple solution to your problem - just cancel all pending request eg. in your viewDidUnload (or dealloc, it depends on your implementation) method.

- (void)viewDidUnload 
{
   ...
   [[[[RKObjectManager sharedManager] client] requestQueue] cancelRequestsWithDelegate:self];
   ...
}
