Question

I’d like to know how to set up an UIButton. I figured the buttonType method, still, I don’t know the method for using CGRectMake() on it.

Also here is a separate doubt: Can I assign a different method @selector for the same button on different methods?

Thanks.

The easiest way is to set it up in a xib file.

If you want to create it manually, use +buttonWithType: as you suggest, set its frame like

// CGRectMake(x, y, width, height)
myButton.frame = CGRectMake(30,30,100,20)

Set its title with

myButton.titleLabel.text = @"Title!";

To set the selector, use

[myButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];

Finally, add it from your view controller with

[self.view addSubview:myButton]

The selector’s method might look like

-(IBAction)buttonClicked:(id)target
{
    NSLog(@"Button clicked!");
}
