Can I get the element by Tag from iOS?

Question

I want to get back a button, I\'ve already assign the tag to there, how can I do so?

Answer 1

UIButton *button=(UIButton *)[self.view viewWithTag:tag]; 

//Now you can get your button based on tag value

Answer 2

//Get View using tag
        UITextField *textFieldInView = (UITextField*)[self.view viewWithTag:sender.tag+1000];
        UILabel *labelInView = (UILabel*)[self.view viewWithTag:sender.tag+2000];

//Print its content based on the tags
        NSLog(@"The tag is %d ", textFieldInView.tag);
        NSLog(@"The tag is %d ", labelInView.tag);
        NSLog(@"The Content is %@ ", textFieldInView.text);
        NSLog(@"The Content is  %@ ", labelInView.text);

Answer 3

Use the viewWithTag method. e.g. if your button is in your controller's view and your button's tag is 100 the following line will return the button:

UIButton *button = (UIButton *)[self.view viewWithTag:100];

EDIT:

Get view with particular tag in Swift -

let view = self.view.viewWithTag(100)

If you want to make sure you have the specific type of view, say a UIButton, you should check the type:

if let button = self.view.viewWithTag(100) as? UIButton {
    //Your code
}
