Question

I just opened my project with Xcode 4.1GM (was using 4.0.2 before). When I enter a number in a textfield I get an EXC Bad Access error but the log doesn’t provide any info so I can’t figure out whats going on. Is there something new in the 4.1 GM that messed this up?

Crash is happening in main.m file at line int retVal = UIApplicationMain(argc, argv, nil, nil);

This is a code that pushes the view and keyboard which is crashing:

- (IBAction)weightButtonPressed
{
    [self.weightView setFrame:CGRectMake(0, self.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height)];
    [self.view addSubview:self.weightView];

    BOOL isKgs = [[NSUserDefaults standardUserDefaults] boolForKey:@"isKgs"];
    if (isKgs)
    {
        self.weightLabel.text = @"0 kgs";   
    }
    else
    {
        self.weightLabel.text = @"0 lbs";   
    }
    self.weightTextField.text = nil;

    UIBarButtonItem *acceptButton = [[UIBarButtonItem alloc]initWithTitle:@"Next" style:UIBarButtonItemStyleDone target:self action:@selector(dismssPickerSetWeight)];
    self.navigationItem.rightBarButtonItem = acceptButton;
    [acceptButton release];

    [weightTextField addTarget:self action:@selector(textFieldDidChange) forControlEvents:UIControlEventEditingChanged];
    self.weightSelectedString = self.weightTextField.text;
    self.weightTextField.hidden = YES;

    [UIView animateWithDuration:.2
                     animations:^
    {[weightTextField becomeFirstResponder]; [self.weightView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];} 
                     completion:^(BOOL finished){}];
}

Does the stack trace where you crash include [AppleSpell init]?

It’s a known bug on Lion with Xcode 4.1 GM seed.

But you installed the final version already, right? Check About Xcode. It should say 4B110. It will probably say 4B95. The Xcode final installer doesn’t properly upgrade the seed.

You need to completely uninstall Xcode 4.1 GM seed first for the Xcode installer to do its job. See the About Xcode.pdf in your /Developer folder.

If you’re not on the 4.1 branch for whatever reason, you could work around this by turning off autocorrect in your viewDidLoad, but make sure you’re using a final build of Xcode for public releases.
