For the tap you can use UIButton's "addTarget:..." method and for the longpress you can add a gesture recognizer:
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(100.0, 100.0, 100.0, 20.0);
[btn setTitle:@"Test" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(userTapped:) forControlEvents:UIControlEventTouchUpInside];
UILongPressGestureRecognizer *gr = [[UILongPressGestureRecognizer alloc] init];
[gr addTarget:self action:@selector(userLongPressed:)];
[btn addGestureRecognizer:gr];
[gr release];
[self.view addSubview:btn];
Of course you need to implement the 2 methods that will be called:
- (void)userTapped:(id)sender {
NSLog(@"user tapped");
}
- (void)userLongPressed:(id)sender {
NSLog(@"user long pressed");
}
Hope that helps.

EDIT: It seems that you are using your button as a BarButtonItem inside a UIToolbar. So I changed my code to do the same:
- (void)viewDidLoad {
[super viewDidLoad];
// set up the button
UIImage *redImage = [UIImage imageNamed:@"TabFav2.png"];
UIButton *tabRedbutton = [UIButton buttonWithType:UIButtonTypeCustom];
tabRedbutton.backgroundColor = [UIColor redColor];
[tabRedbutton setImage:redImage forState:UIControlStateNormal];
tabRedbutton.frame = CGRectMake(0.0, 0.0, 50,35);
// set up a bar button item with the button as its view
UIBarButtonItem *redTab = [[UIBarButtonItem alloc] initWithCustomView:tabRedbutton];
// set up toolbar and add the button as a bar button item
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0, 100.0, 768.0, 40.0)];
toolbar.barStyle = UIBarStyleBlack;
NSArray *items = [NSArray arrayWithObject:redTab];
[toolbar setItems:items];
[self.view addSubview:toolbar];
[toolbar release];
// add tap handler to button for tap
[tabRedbutton addTarget:self action:@selector(redbottonmethod) forControlEvents:UIControlEventTouchUpInside];
// add gesture recognizer to button for longpress
UILongPressGestureRecognizer *longpressGesture1 = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressHandler:)];
longpressGesture1.minimumPressDuration =0.1;
[tabRedbutton addGestureRecognizer:longpressGesture1];
[longpressGesture1 release];
}
And the two methods that get called:
- (void)longPressHandler:(UILongPressGestureRecognizer *)gestureRecognizer {
NSLog(@"Long press");
}
-(void)redbottonmethod {
NSLog(@"single tapped");
}
This code definitely works.
By the way: I noticed that in your code in the 2 methods that get called you have typo: You must use NSLog() and not NSlog(). Could that be the problem?
