Delete custom UIView randomly Doesn't work fast 3
I am creating an iOS app in swift 3 where I am creating a dynamic UIView. I need to delete a custom view in a random way.
class ViewController: UIViewController {
var myView: subView!
var y : CGFloat!
@IBOutlet weak var addButton: UIButton!
override func viewDidLoad() {
y = 1
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func cancelbutton(_ sender: UIButton)
{
myView.removeFromSuperview()
}
@IBAction func buttonAction(_ sender: Any) {
y = y + 110
myView = subView(frame: CGRect(x: 80, y: y, width: 300, height: 100))
myView.backgroundColor = UIColor.green
myView.actionButton.addTarget(self, action: (#selector(cancelbutton(_:))), for: UIControlEvents.touchUpInside)
self.view.addSubview(myView)
}
above image is my custom view
above image is my output sample
When I click the close button, only one subhead wants to be closed, which is the one I was selected. "Thanks in advance"

There are several ways to achieve this,
I would suggest this.
//1. Create a new class inherited from UIView → Say "CustomView".
// 2. Make "Protocol" in the "CustomView" header. → Say "CustomViewDelegate"
@protocol CustomViewDelegate
@optional
- (void)didCloseButtonClickedWithView:(CustomView *)view;
@end
and delegate correctly in the header.
@property (nonatomic) id <CustomViewDelegate> delegate;
// 3. in CustomView.m → Add an action for the Close button. (via Storyboard or Programmatically, whichever you prefer).
- (void)closeClicked:(UIButton *)button
{
}
And call the delegate using the "Protocol" method,
- (void)closeClicked:(UIButton *)button
{
if (self.delegate && [self.delegate respondsToSelector:@(didCloseButtonClickedWithView:)])
{
[self.delegate didCloseButtonClickedWithView:self]; // passing self is 'CustomView'
}
}
//4. Make CustomView objects in your ViewController.
CustomView *view = [[CustomView alloc] initWithFrame:...];
view.delegate = self;
[self.view addSubview:view];
//five. Inject CustomViewDelegate into your ViewController.
- (void)didCloseButtonClickedWithView:(CustomView *)view
{
// you will get action of close button here
// remove your view here.
[view removeFromSuperview];
// Additional tips:
// Re-arrange frames for other views.
}
