不确定在对象上何处调用释放。帮帮我？

Question

我有一个类可以处理iPhone上的所有网络访问。我用它的方式如下：

-(void) randomFunction: 
{ 
    // Assign params etc. <br /> 
    TTNetworkAccessLib *nLib = [[TTNetworkAccessLib alloc] initWithParams:..]; 
    [nLib createAndStartRequest]; 
    // Can't release here since the request is async and is still running. 
} 

-(void) requestSucceded:(NSData *) data 
{ 
    // Can pass a reference to the request object and release here, but doesn't seem right? 
} 

-(void) requestFailed:(int) responseCode 
{ 
    // Can pass a reference to the request object and release here, but doesn't seem right? 
} 

Answer 1

当我创建一个异步执行某个对象的对象时，我通常会在启动该过程时保留它自己，并在完成并完成任何回调后释放它自己。这样，创建它的代码可以在以后不需要它时释放它，并且我知道在该过程完成之前它不会被释放。

有了这样的委托，我会建议使用自动释放 TNetworkAccessLib * nLib = [[[TTNetworkAccessLib页头] initWithParams：..]自动释放]。
