Question

How I can loop some action in Cocoa? For example I want that random numbers change in textField every 1 sec.

Answer 1

Example:

 -(void)awakeFromNib {

    [NSTimer scheduledTimerWithTimeInterval:1
                                 target:self
                               selector:@selector(changeTextFieldsInt:)
                               userInfo:nil
                                repeats:YES];
}

- (void)changeTextFieldsInt:(NSTimer *)time {
     [textField setIntValue:rand()];
}

Don’t forget IBoutlet textField.
