How do I create a basic UIButton programmatically?

Question

How can I create a basic UIButton programmatically? For example in my view controller, when executing the viewDidLoad method, three UIButtons will be created dynamically and its layout or properties are set.

http://webindream.com/how-to-add-uibutton-programmatically-in-swift/ has a good tutorial to add uibutton programmatically — farhad rubel, Sep 26 '16 at 11:10

Here's one:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];

Thanks! can you explain to me what is aMethod? – domlao Sep 04 '09 at 12:43
aMethod is your own defined method which will respond to the button press. (For me)It takes an id object. – John Smith Sep 04 '09 at 16:49
When the button is manipulated (pressed and held down, or pressed and released or dragged through, etc) you want something to happen, right? The code that you want called is usually a method like: - (void) myButtonWasPressed or - (void) myButtonWasPressed:(id) whichButton That's what I am talking about. – mahboudz Sep 04 '09 at 19:49
The aMethod is kinda like and IBaction that is called when the button is tapped. – David Jul 09 '10 at 11:05
You don't need [UIButton alloc] to reserve memory? Or does buttonWithType: handle this? – Casey Flynn Apr 13 '11 at 21:35

buttonWithType: returns an autoreleased instance of UIButton – Allyn Apr 14 '11 at 21:05
267

Handy Tip: If you don't want your button to activate as soon as you touch it, use UIControlEventTouchUpInside instead of UIControlEventTouchDown - this will wait for the user to lift their finger, giving them the option of cancelling by dragging away (recommended in Apple Human Interface Guidelines) – ayreguitar Jul 29 '11 at 15:33
buttonWithType is cerated as autoreleased, but then when -addSubview is called, the button is retained until it is removed from the view. – mahboudz Sep 30 '11 at 17:45

I do recommend using UIControlEventTouchUpInside for most cases. I have used UIControlEventTouchDown in some games and music playing apps (ClefTunes and ClefNotes) so that the touch immediately generates music notes. – mahboudz Sep 30 '11 at 17:47

Note for the people like me that struggled with this--@selector(aMethod:) refers to a method with an argument. @selector(aMethod) refers to a method with no argument. If your method signature looks like -(void) aMethod; and you use @selector(aMethod:), your app will crash. – Chad Schultz Oct 16 '12 at 17:31
On iOS 7.0 you may want to customize the button more. I have a [iOS 7.0 UIButton code and animations](http://iphonedev.tv/blog/2014/1/22/programmatic-uibutton-on-ios-70-create-a-uibutton-with-code) to show UIButton variations. – Paul Solt Apr 03 '14 at 15:41

 [but setFrame:CGRectMake(52, 252, 215, 40)];

-(void) buttonClicked:(UIButton*)sender
 {
NSLog(@"you clicked on button %@", sender.tag);
 }

Swift

    let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)
    myButton.setTitle("Hai Touch Me", forState: .Normal)
    myButton.setTitleColor(UIColor.blueColor(), forState: .Normal)
    myButton.frame = CGRectMake(15, 50, 300, 500)
    myButton.addTarget(self, action: "pressedAction:", forControlEvents: .TouchUpInside)

    self.view.addSubview( myButton)


func pressedAction(sender: UIButton!) {
   // do your stuff here 
  NSLog("you clicked on button %@", sender.tag)

    myButton.setTitle("Hi, Click me", for: .normal)
    myButton.setTitleColor(UIColor.blue, for: .normal)
    myButton.frame = CGRect(x: 15, y: 50, width: 300, height: 500)

    myButton.addTarget(self, action: #selector(pressedAction(_:)), for: .touchUpInside)
    self.view.addSubview( myButton)



func pressedAction(_ sender: UIButton) {
   // do your stuff here

To add a button programatically to your controller's view, use the following:

-(void)viewDidLoad
{
   UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
   btn.frame = CGRectMake(0, 0, 100, 50);
   [btn setTitle:@"Hello, world!" forState:UIControlStateNormal];
   [self.view addSubview:btn];
}

To add three of these, rinse and repeat.

Here you can create dynamically a UIButton:

//For button image
UIImage *closebtnimg = [UIImage imageNamed:@"close_btn.png"];
//Custom type button
btnclose = [[UIButton buttonWithType:UIButtonTypeCustom]retain];
//Set frame of button means position
btnclose.frame = CGRectMake(103, 257, 94, 32);
//Button with 0 border so it's shape like image shape
[btnclose.layer setBorderWidth:0];
//Set title of button
[btnclose setTitle:@"CLOSE" forState:UIControlStateNormal];
[btnclose addTarget:self action:@selector(methodname:) forControlEvents:UIControlEventTouchUpInside];
//Font size of title
btnclose.titleLabel.font = [UIFont boldSystemFontOfSize:14];
//Set image of button
[btnclose setBackgroundImage:closebtnimg forState:UIControlStateNormal];

Come on, it's 2014! Why isn't code block evaluation assignment being used yet, as trends show it's the future!

UIButton* button = ({
    //initialize button with frame
    UIButton* button = [[UIButton alloc] initWithFrame:({
        CGRect frame = CGRectMake(10.0, 10.0, 200.0, 75.0);
        frame;
    })];
    //set button background color
    [button setBackgroundColor:({
        UIColor* color = [UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0];
        color;
    })];
    //set button title for state
    [button setTitle:({
        NSString* string = [NSString stringWithFormat:@"title words"];
        string;
    }) forState:({
        UIControlState state = UIControlStateNormal;
        state;
    })];
    //set selector
    [button addTarget:self action:({
        SEL select = @selector(method:);
        select;
    }) forControlEvents:({
        UIControlEvents event = UIControlEventTouchUpInside;
        event;
    })];
    //return button
    button;
});
[self.view addSubview:button];

whoa!

Or the exact results can be accomplished as such:

UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(10.0, 10.0, 200.0, 75.0)];
[button setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0]];
[button setTitle:@"title words" forState:UIControlStateNormal];
[button addTarget:self action:@selector(method:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];

that is the string to pass as a parameter just for additional info, you can also use that method like this -(void) myButtonClick{ NSLog(@"you clicked on button"); } but be sure that while calling the method remove the : just use like this [myButton addTarget:self action:@selector(myButtonClick) forControlEvents:UIControlEventTouchUpInside]; – ashokdy Aug 15 '13 at 15:16

btnTest.titleLabel?.numberOfLines = 2
btnTest.titleLabel?.textAlignment = .center
btnTest.setTitleColor(UIColor.gray, for: .normal)

 [btn addTarget:self action:@selector(btnAction) forControlEvents:UIControlEventTouchDragInside];
 [btn setTitle:@"click button" forState:UIControlStateNormal];
  btn.frame = CGRectMake(50, 100, 80, 40);

You can implement it in your ViewDidLoad Method:

continuebtn = [[UIButton alloc]initWithFrame:CGRectMake(10, 100, view1.frame.size.width-20, 40)];
    [continuebtn setBackgroundColor:[UIColor grayColor]];
    [continuebtn setTitle:@"Continue" forState:UIControlStateNormal];
    continuebtn.layer.cornerRadius = 10;
    continuebtn.layer.borderWidth =1.0;
    continuebtn.layer.borderColor = [UIColor blackColor].CGColor;
    [continuebtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [continuebtn addTarget:self action:@selector(continuetonext) forControlEvents:UIControlEventTouchUpInside];
    [view1 addSubview:continuebtn];

Where continuetonext is:

-(void)continuetonext
{
    GeneratePasswordVC *u = [[GeneratePasswordVC alloc]init];
    [self.navigationController pushViewController:u animated:YES];
}

For Swift 2.2 (with the with the new "selector" declaration).

let btn = UIButton(type: UIButtonType.System) as UIButton
btn.frame = CGRectMake(0, 0, 100, 20) // set any frame you want
btn.setTitle("MyAction", forState: UIControlState.Normal)
btn.addTarget(self, action: #selector(MyClass.myAction(_:)), forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(btn)


func myAction(sender:UIButton!){
  // Some action 
}

As of Swift 3, several changes have been made to the syntax.

Here is how you would go about creating a basic button as of Swift 3:

    let button = UIButton(type: UIButtonType.system) as UIButton
    button.frame = CGRect(x: 100, y: 100, width: 100, height: 50)
    button.backgroundColor = UIColor.green
    button.setTitle("Example Button", for: UIControlState.normal)
    self.view.addSubview(button)

Here are the changes that have been made since previous versions of Swift:

let button = UIButton(type: UIButtonType.System) as UIButton

// system no longer capitalised

button.frame = CGRectMake(100, 100, 100, 50)

// CGRectMake has been removed as of Swift 3

button.backgroundColor = UIColor.greenColor()

// greenColor replaced with green

button.setTitle("Example Button", forState: UIControlState.Normal)

// normal is no longer capitalised

self.view.addSubview(button)

try this:

first write this in your .h file of viewcontroller

UIButton *btn;

Now write this in your .m file of viewcontrollers viewDidLoad.

btn=[[UIButton alloc]initWithFrame:CGRectMake(50, 20, 30, 30)];
[btn setBackgroundColor:[UIColor orangeColor]];
[btn setTitle: @"My Button" forState:UIControlStateNormal];
[btn setTitleColor: [UIColor blueVolor] forState:UIControlStateNormal];
[btn.layer setBorderWidth:1.0f];
[btn.layer setBorderColor:[UIColor BlueVolor].CGColor];
//adding action programatically
[btn addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];

write this outside viewDidLoad method in .m file of your view controller

- (IBAction)btnClicked:(id)sender
{
  //Write a code you want to execute on buttons click event
}

For Swift 3 (even shorter code)

let button = UIButton(type: UIButtonType.custom)
button.frame = CGRect(x: 0, y: 0, width: 200.0, height: 40.0)
button.addTarget(nil, action: #selector(tapButton(_:)), for: UIControlEvents.touchUpInside)
button.tintColor = UIColor.white
button.backgroundColor = UIColor.red
button.setBackgroundImage(UIImage(named: "ImageName"), for: UIControlState.normal)
button.setTitle("MyTitle", for: UIControlState.normal)
button.isEnabled = true

func tapButton(sender: UIButton) {

}

The Swift 3 version should be:

let myButton:UIButton = {
    let myButton = UIButton() // If you want to set the type use like
                              // UIButton(type: .RoundedRect) or
                              // UIButton(type: .Custom)
    myButton.setTitle("Hai Touch Me", for: .normal)
    myButton.setTitleColor(UIColor.blue, for: .normal)
    myButton.frame = CGRect(x: 20, y: 20, width: 100, height: 40)

    myButton.addTarget(self, action: #selector(ViewController.pressedAction(_:)), for: .touchUpInside)
    self.view.addSubview(myButton)

    return myButton
}()

In Swift 5 and Xcode 10.2

Basically we have two types of buttons.

1) System type button

2) Custom type button (In custom type button we can set background image for button)

And these two types of buttons has few control states https://developer.apple.com/documentation/uikit/uicontrol/state

Important states are

1) Normal state

2) Selected state

3) Highlighted state

4) Disabled state etc...

//For system type button
let button = UIButton(type: .system)
button.frame = CGRect(x: 100, y: 250, width: 100, height: 50)
//  button.backgroundColor = .blue
button.setTitle("Button", for: .normal)
button.setTitleColor(.white, for: .normal)
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 13.0)
button.titleLabel?.textAlignment = .center//Text alighment center
button.titleLabel?.numberOfLines = 0//To display multiple lines in UIButton
button.titleLabel?.lineBreakMode = .byWordWrapping//By word wrapping
button.tag = 1//To assign tag value
button.btnProperties()//Call UIButton properties from extension function
button.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)
self.view.addSubview(button)

//For custom type button (add image to your button)
let button2 = UIButton(type: .custom)
button2.frame = CGRect(x: 100, y: 400, width: 100, height: 50)
//        button2.backgroundColor = .blue
button2.setImage(UIImage.init(named: "img.png"), for: .normal)
button2.tag = 2
button2.btnProperties()//Call UIButton properties from extension function
button2.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)
self.view.addSubview(button2)

@objc func buttonClicked(sender:UIButton) {
    print("Button \(sender.tag) clicked")
}

//You can add UIButton properties using extension
extension UIButton {
    func btnProperties() {
        layer.cornerRadius = 10//Set button corner radious
        clipsToBounds = true
        backgroundColor = .blue//Set background colour
        //titleLabel?.textAlignment = .center//add properties like this
    }
}
