Question

Shortly, I am parsing a xml file and getting user MD5 password. Now when i am comparing parsed password and user given password in a text field then i am finding Program received signal: “EXC_BAD_ACCESS”

when i do not compare between these password then code execute.Here is my code.

if([checkingParsedPassword isEqualToString:passwordMD5String]){
tabbarController = [[TabbarController alloc] initWithNibName:@"TabbarController" bundle:nil];
UINavigationController *myTabbarController = [[[UINavigationController alloc] initWithRootViewController:tabbarController] autorelease];
myTabbarController.navigationBar.barStyle = UIBarStyleBlackOpaque;
[self.navigationController presentModalViewController:myTabbarController animated:YES];
[tabbarController release];    
}

If i have to give u any more information then please don’t hesitate because i am in serious problem.

EDIT

when i am using NSLog…i can see both string.

 NSLog(@"The parsed pass: %@ and the user pass: %@ ",checkingParsedPassword, passwordMD5String);

but when i try to compare then i got these exc_bad_access on if condition

if([checkingParsedPassword isEqualToString:passwordMD5String]){
    NSLog(@"checked");
}

Answer 1

The converted password from md5 might not be a UTF8string,so try converting md5 password in a string like

passwordMD5String=[NSString stringWithFormat:@"%@",passwordMD5String];

before comparing.
