UIButton *but= [UIButton buttonWithType:UIButtonTypeRoundedRect];
[but addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[but setFrame:CGRectMake(52, 252, 215, 40)];
[but setTitle:@"Login" forState:UIControlStateNormal];
[but setExclusiveTouch:YES];
// if you like to add backgroundImage else no need
[but setbackgroundImage:[UIImage imageNamed:@"XXX.png"] forState:UIControlStateNormal];
[self.view addSubview:but];

Szybki
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)
}
Swift3 i wyżej
let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)
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
print("you clicked on button \(sender.tag)")
}
SwiftUI
na przykład implementacja krok po kroku pochodzi z portalu SwiftUI Developer
import SwiftUI
struct ContentView : View {
var body: some View {
VStack {
Text("Target Color Black")
Button(action: {
/* handle button action here */ })
{
Text("your Button Name")
.color(.white)
.padding(10)
.background(Color.blue)
.cornerRadius(5)
.shadow(radius: 5)
.clipShape(RoundedRectangle(cornerRadius: 5))
}
}
}
}
#if DEBUG
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}
#endif
