copied!<p>I'm trying to send some data to a PHP script online to submit online scores for my iOS application.</p> <p>The script will require account credentials formatted with the proper escape characters for a HTTP request. It's the setHTTPBody method which cashes the application:</p> <pre><code> [text_field removeFromSuperview]; text_field.text = @""; //Remove text so it doesn't show because the text field is still on top of the open gl view text_field.enabled = NO; NSMutableURLRequest * request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"secret"] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:10.0]; [request setHTTPMethod: @"POST"]; [request setHTTPBody: [[NSString stringWithFormat:@"username=%@&password=%@&score=%i",[ogl_view->username stringByAddingPercentEscapesUsingEncoding:NSUnicodeStringEncoding],[text_field.text stringByAddingPercentEscapesUsingEncoding:NSUnicodeStringEncoding],ogl_view->score[0]] dataUsingEncoding:NSUnicodeStringEncoding]]; NSURLConnection * connection = [[NSURLConnection alloc] initWithRequest: request delegate:self]; if (connection){ received_data = [[NSMutableData data] retain]; ogl_view->section = CURLING_PROCESS_CREDENTIALS; }else{ ogl_view->section = CURLING_LOGIN_OR_REGISTER; UIAlertView *connection_alert = [[UIAlertView alloc] initWithTitle:@"Error" message: @"Can't connect to server" delegate:nil cancelButtonTitle:@"Close" otherButtonTitles: nil]; [connection_alert show]; [connection_alert release]; } </code></pre> <p>I've found that it crashes at the point that the setHTTPBody method is called. Does anyone know why?</p> <p>Thank you for any answer.</p> <p>Edit: Here's the crash log:</p> <pre><code> 2010-09-02 19:02:30.291 iPhone Monkey Curling[431:207] -[DOMText stringByAddingPercentEscapesUsingEncoding:]: unrecognized selector sent to instance 0x5c97ce0 2010-09-02 19:02:30.293 iPhone Monkey Curling[431:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[DOMText stringByAddingPercentEscapesUsingEncoding:]: unrecognized selector sent to instance 0x5c97ce0' *** Call stack at first throw: ( 0 CoreFoundation 0x02531919 __exceptionPreprocess + 185 1 libobjc.A.dylib 0x0267f5de objc_exception_throw + 47 2 CoreFoundation 0x0253342b -[NSObject(NSObject) doesNotRecognizeSelector:] + 187 3 CoreFoundation 0x024a3116 ___forwarding___ + 966 4 CoreFoundation 0x024a2cd2 _CF_forwarding_prep_0 + 50 5 iPhone Monkey Curling 0x00004338 -[PasswordFieldDelegate textFieldShouldReturn:] + 450 6 UIKit 0x00699358 -[UIKeyboardImpl callShouldInsertText:] + 148 7 UIKit 0x05f29c86 -[UIKeyboardImplAccessibility(SafeCategory) callShouldInsertText:] + 70 8 UIKit 0x006a0693 -[UIKeyboardImpl addInputString:fromVariantKey:] + 107 9 UIKit 0x006a2957 -[UIKeyboardImpl handleKeyEvent:] + 1723 10 UIKit 0x007c31c0 -[UIKeyboardLayoutStar sendStringAction:forKey:] + 684 11 UIKit 0x007c79ba -[UIKeyboardLayoutStar touchUp:] + 2556 12 UIKit 0x006b99a3 -[UIKeyboardLayout touchesEnded:withEvent:] + 550 13 UIKit 0x0058a2ff -[UIWindow _sendTouchesForEvent:] + 567 14 UIKit 0x0056c1ec -[UIApplication sendEvent:] + 447 15 UIKit 0x00570ac4 _UIApplicationHandleEvent + 7495 16 GraphicsServices 0x02d97afa PurpleEventCallback + 1578 17 CoreFoundation 0x02512dc4 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 52 18 CoreFoundation 0x02473737 __CFRunLoopDoSource1 + 215 19 CoreFoundation 0x024709c3 __CFRunLoopRun + 979 20 CoreFoundation 0x02470280 CFRunLoopRunSpecific + 208 21 CoreFoundation 0x024701a1 CFRunLoopRunInMode + 97 22 GraphicsServices 0x02d962c8 GSEventRunModal + 217 23 GraphicsServices 0x02d9638d GSEventRun + 115 24 UIKit 0x00574b58 UIApplicationMain + 1160 25 iPhone Monkey Curling 0x00002388 main + 102 26 iPhone Monkey Curling 0x00002319 start + 53 ) </code></pre>
