Answer 1

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
}
