如何將附加參數傳遞給ASIHTTPRequest didFinishSelector選擇器

Question

使用ASIHTTPRequest爲我們的其餘api構建api。

Api將所有請求包裝到它自己的方法中。

- (void) foo:(id)caller 
    andSuccessCallback:(SEL)successCallback 
    andFailureCallback:(SEL)failureCallback { 

    _currentCaller=caller; 
    _currentSuccessCallback=successCallback; 
    _currentFailureCallback=failureCallback; 

    NSString *urlString = @"http://localhost/foo"; 
    NSURL *url= [NSURL URLWithString: urlString]; 
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; 
    [request setDelegate:self]; 
    [request setDidFinishSelector:@selector(fooSuccess:)]; 
    [request startAsynchronous]; 
} 

- (void) fooSuccess:(ASIHTTPRequest *)request { 
    if (statusCode >=400) { 
    if ([_currentCaller respondsToSelector:_currentFailureCallback]) 
     [_currentCaller performSelector:_currentFailureCallback withObject:statusCode withObject:message]; 
} else { 
    if ([_currentCaller respondsToSelector:_currentSuccessCallback]) 
     [_currentCaller performSelector:_currentSuccessCallback]; 
} 
    [request release]; 
} 

目前通過回調選擇我使用類私有變量_currentCaller _currentSuccessCallback _currentFailureCallback = failureCallback

我可以把它們傳遞給直接fooSuccess回調？

您可以通過填充NSDictionary並將其設置爲請求的userInfo屬性來傳遞對象。
