URLリクエストをWebサーバーに送信する際に+文字を処理する方法

Question

サーバーにリクエストに+文字の強制電話番号などの詳細を掲示して問題が発生しました。サーバー側に+文字が表示されません。

curl = [curl stringByAppendingString:@"name="]; 
    curl = [curl stringByAppendingString:profileObj.name]; 
    curl = [curl stringByAppendingString:@"&email="]; 
    curl = [curl stringByAppendingString:profileObj.email]; 
    curl = [curl stringByAppendingString:@"&password="]; 
    curl = [curl stringByAppendingString:profileObj.password]; 
    curl = [curl stringByAppendingString:@"&phoneno="]; 
    curl = [curl stringByAppendingString:profileObj.phoneno]; // here my data is +919999999999 
    curl = [curl stringByAppendingString:@"&address="]; 
    curl = [curl stringByAppendingString:profileObj.address]; 
    curl = [curl stringByReplacingOccurrencesOfString:@"\n" withString:@""]; 

    NSString *escapedUrlString = [curl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 

    NSURL *finalURL = [NSURL URLWithString:escapedUrlString]; 

    [self updateStatus]; 
    if (internetConnectionStatus == NotReachable) 
    { 
     UIAlertView *reachbleAlert = [[UIAlertView alloc] initWithTitle:@"Network Error" 
                message:@"No Network Available. \n This Application requires network connectivity. " 
                delegate:self 
             cancelButtonTitle:@"Ok" 
             otherButtonTitles: nil]; 
     [reachbleAlert show]; 
     [reachbleAlert release]; 
     return; 
    } 
    else 
    { 

     NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; 
     NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:finalURL 
                    cachePolicy:NSURLRequestReloadIgnoringCacheData 
                   timeoutInterval:10]; 
     [theRequest setHTTPMethod:@"POST"]; 

     [[[NSURLConnection alloc] initWithRequest:theRequest delegate:self] autorelease]; 

     [pool release]; 

    } 

私はラインの下に使用されます。サーバーに要求する前に

NSString *escapedUrlString = [curl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 

。ですから、+文字を扱うための解決策を教えてください。

Answer 1

よく、+はURL内の有効な文字なので、無視されます。stringByAddingPercentEscapesUsingEncoding:+記号をURLに挿入する前に手動で逃げてください。

... 
curl = [curl stringByAppendingString:@"&phoneno="]; 
curl = [curl stringByAppendingString: [profileObj.phoneno stringByReplacingOccurencesOfString: @"+" with: @"%2B"]]; // here my data is +919999999999 
... 

%2BについてNBわかりません。 2Bか2Bでなければ、それは問題です。
