Im working on a tiny app just to learn cocoa, and Im having a hard time with setting FirstResponder to some NSTextFields.
When the view opens, I want the first NSTextField, clientNumber, to be selected, so I trigger [clientNumber becomeFirstResponder] at the end of my loadView method, but it does not select the text field.
But when I click the button that fires the (IBAction)addToArray method, it selects the right text field. Further do I have another text field, it should contain integers only, so I have a crude verification for it. When the content is not a int, I get a beep, just like it should, but it does not select the text field.
Here is my code:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
NSLog(@"initWithNibName");
}
return self;
}
- (void)viewWillLoad {
NSLog(@"viewWillLoad");
}
- (void)viewDidLoad {
NSLog(@"viewDidLoad");
[self initNewInvoice];
}
- (void)loadView {
NSLog(@"loadView");
[self viewWillLoad];
[super loadView];
[self viewDidLoad];
[clientNumber becomeFirstResponder];
}
- (void)awakeFromNib
{
NSLog(@"awakeFromNib");
}
- (IBAction)saveInvoice:(id)sender
{
[invoiceCredit becomeFirstResponder];
}
- (IBAction)addToArray:(id)sender
{
[clientNumber setStringValue: @"Toodeloo"];
[clientNumber becomeFirstResponder];
}
- (IBAction)updateCreditDays:(id)sender
{
if(invoiceCredit.intValue){
[self updateCredit];
}else{
NSBeep();
[invoiceCredit becomeFirstResponder];
}
}
I really hope someone can help me out here.
Regards,
GJ Nilsen
