    text
    copied!<p>I am using modal views in my iphone application. The problem is that the views are working on the simulator but when I am installing it on the device, instead of the modal views,instead it shows a white blank screen . Anyone encountered this problem before? How do i solve this? The following is the code. </p> <pre><code>#import "ResetPWD.h" #import "WebServiceController.h" #import "ProductAppDelegate.h" @implementation ResetPWD @synthesize oldPWD; @synthesize newPWD; @synthesize newPWD2; @synthesize password1; @synthesize password2; -(IBAction)done:(id)sender { NSString *pwd = oldPWD.text; NSString *pwd1 = newPWD.text; NSString *pwd2 = newPWD2.text; if(!self.oldPWD.text ) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Please Enter Old Password." delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; return; } if(!self.newPWD.text ) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Please Enter New Password." delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; return; } if ([pwd1 length]&lt;6) { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:@"New password should be atleast 6 characters long" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; [alert release]; return; } if (![pwd1 isEqualToString:pwd2]) { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:@"Passwords do not match" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; [alert release]; return; } password1 = pwd; password2 = pwd1; NSMutableArray *data = [[NSMutableArray alloc]init]; [data addObject:password1]; [data addObject:password2]; WebServiceController *webCall = [[WebServiceController alloc]init]; NSDictionary *dict = [webCall resetPWD:data]; NSString * nVal = [dict objectForKey:@"ErrorCode"]; NSString *errorDesc = [dict objectForKey:@"ErrorType"]; NSString *errorString = [dict objectForKey:@"ErrorString"]; int n=[nVal integerValue]; if(n&gt;=3) { errorString=[[NSString alloc]initWithFormat:@"%@\nProceed to broker registration.",errorString]; } UIAlertView *successAlert=[[UIAlertView alloc]initWithTitle:errorDesc message:errorString delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [successAlert show]; [successAlert release]; [self.parentViewController dismissModalViewControllerAnimated:YES]; } -(IBAction)cancel:(id)sender { [self.parentViewController dismissModalViewControllerAnimated:YES]; } - (void)textFieldDidBeginEditing:(UITextField *)textField { CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField]; CGRect viewRect = [self.view.window convertRect:self.view.bounds fromView:self.view]; CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height; //if (textField == usernameField) // midline+=20; CGFloat numerator = midline - viewRect.origin.y - MINIMUM_SCROLL_FRACTION * viewRect.size.height; CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) * viewRect.size.height; CGFloat heightFraction = numerator / denominator; if (heightFraction &lt; 0.0) { heightFraction = 0.0; } else if (heightFraction &gt; 1.0) { heightFraction = 1.0; } animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction); CGRect viewFrame = self.view.frame; viewFrame.origin.y -= animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [self.view setFrame:viewFrame]; [UIView commitAnimations]; } - (void)textFieldDidEndEditing:(UITextField *)textField { CGRect viewFrame = self.view.frame; viewFrame.origin.y += animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [self.view setFrame:viewFrame]; [UIView commitAnimations]; } - (BOOL)textFieldShouldReturn:(UITextField *)textField { // the user pressed the "Done" button, so dismiss the keyboard [textField resignFirstResponder]; return NO; } // The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. /* - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization. } return self; } */ /* // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } */ /* // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations. return (interfaceOrientation == UIInterfaceOrientationPortrait); } */ - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc. that aren't in use. } - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end </code></pre> <p>this view is not showing on the device, but showing on the simulator. also the designing is done in a xib file.</p>
