urlConnection委託處理同一類中的多個答案

Question

我有一個ViewController.m文件，它帶有2個打開urlConnection的按鈕，我需要處理響應。 我的問題是，當連接來自按鈕1（abilita）或按鈕2（登錄）時，我在委託中無法理解。 我該怎麼辦？

-(IBAction)abilita { 

    NSString *usernameEncoded = [username.text urlencode]; 
    NSString *passwordEncoded = [password.text urlencode]; 
    NSString *mittenteEncoded = [abilitaField.text urlencode]; 
    NSString *code=@"abcdef"; 

    NSString * address = [NSString stringWithFormat:@"http://www.xxx.net/smsweb/setsender/recsender.php?login=%25%40&password=%25%40&codice%@",usernameEncoded, passwordEncoded,code]; 

    NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:address]]; 
    urlConnectionRecsender=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 
} 


- (IBAction)login { 
    NSString * address = [NSString stringWithFormat:@"http://www.xxx.net/smsscript/sendsms.php?login=%25%40&password=%25%40&tipo=2",usernameEncoded, passwordEncoded]; 

    NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:address]]; 
    urlConnectionLogin=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 
} 

//DELEGATE: 

- (void)connection:(NSURLConnection *)conn didReceiveResponse:(NSURLResponse *)response 
{ 
     mutableData = [NSMutableData data] ; 
     if ([conn isEquals:urlConnectionRecsender]){ 
      // this is request urlConnectionRecsender 
     } 
     if ([conn isEquals:urlConnectionLogin]){ 
      // this is request urlConnectionLogin 
     } 
} 

- (void)connectionDidFinishLoading:(NSURLConnection *)conn 
{ 
    NSMutableString *stringData = [[NSMutableString alloc] initWithData:mutableData encoding: NSASCIIStringEncoding]; 
} 

你可以寫我可以理解connectionDidFinishLoading我在處理什麼連接方式的代碼？

Answer 1

採取urlConnection1 & urlConnection2爲2個不同的變量，然後在connectionDidFinishLoading或didReceiveResponse方法對它們進行比較如下：

if ([conn isEquals:urlConnection1]){ 
    // First urlConnection 
} 
if ([conn isEquals:urlConnection2]){ 
    // Second urlConnection 
} 

希望它可以幫助...
