Hello guys I want to create a UIButton programmatically from every object in an array. something like
for answer in answers {
//create button
}
But how do I assign all these buttons a randomized and unique variable?
like var randomvar = UIButton() ?
I had this problem when I was new to OOP x).
Basically a variable when handling an object is just a pointer to the address in memory.
An array with objects will actually be an array with pointers to all unique objects, in your case these objects are UIButton's.
So in your for-loop you have to add those buttons inside another array.
var buttons = [UIButton]()
for answer in answers {
let btn = UIButton()
...
buttons.append(btn)
}
Then you can access each unique button by accessing them trough buttons.
buttons[2].setTitle("test 2", forControlEvent: .Normal)
Loop over your array and create the button for each item. Either add it to your view directly or save it into an array for later access
var buttons = [UIButton]()
for answers in answer {
let button = UIButton(...)
button.addTarget(self, action: "buttonAction:", forControlEvents: . TouchUpInside)
// add to a view
button.frame = ...
view.addSubview(button)
// or save for later use
buttons.append(button)
}
The better approach is to create an array property:
var array: [UIButton]?
and inside the loop create a button and add it to this array.
If you need to access any button you can access it by index.
