Hi everyone, My project is exhibiting a particularly strange behavior. I have a UIViewController subclass which has been pushed into a UINavigationController with pushViewController:. In the UIViewController, there are some UITextFields and a UITableView whose delegate and data source is set to the UIViewController subclass (I manually implement UITableViewDataSource and UITableViewDelegate). The thing is, whenever I click inside one of the UITextFields to edit it, program execution stops, like if it hit a debugger breakpoint. Only, the "breakpoint" stops on this line on main.m Code: int retVal = UIApplicationMain(argc, argv, nil, nil); Beside the line, the following text appears Code: Thread 1: Program recieved signal: 'EXC_BAD_ACCESS' There are no events currently connected to the UITextFields, so their default behavior should be to show which ever keyboard I specified on IB. No error messages are reported on the gdb pane. I am using XCode 4. Can anyone help me troubleshoot this error? Thanks in advance.
