Add placeholder to UITextView Swift

There are instances where we need to use UITextView as a multi-line text field in our app. The UITextView does not provide a placeholder property like the UITextField. So, in order to achieve this we need to implement the following methods in our UIViewController:

class DemoVC: UIViewController, UITextViewDelegate { //hook this to the storyboard UITextView @IBOutlet weak var…

UIlabel 대신에 UITextView를 자주 사용하는데 그 이유

brian은 UIlabel 대신에 UITextView를 자주 사용하는데 그 이유는 UITextView는 ui가 위해야할 위치의 최대 위로 붙여서 생성되지만 UIlabel는 중간 위치에서 생성되기 때문이다.

By default UITextFielf doesn't have a placeholder property like UITextField, so it has to be manipulate programmatically.

First adopt UITextViewDelegate and then set the placeholder text in viewDidLoad:

messageTextView.delegate = self messageTextView.text = placeholderText messageTextView.textColor = UIColor.lightGrayColor()

Text View delegate methods:

var placeholderText = "Compose message" func textViewShouldBeginEditing(textView: UITextView) -> Bool {    if messageTextView.text == placeholderText        messageTextView.text = ""        messageTextView.textColor = UIColor.blackColor()    }    return true } func textViewShouldEndEditing(textView: UITextView) -> Bool {    if textView.text.isEmpty {        messageTextView.text = placeholderText        messageTextView.textColor = UIColor.lightGrayColor()    }    return true }

How to lose margin/padding in UITextView?

I have a UITextView in my iOS Application, which displays a large amount of text. I am then paging this text by using the offset margin parameter of the UITextView. My problem is that the padding of the UITextView is confusing my calculations as it seems to be different depending on the font size and typeface that I use.

Therefore, I pose the question:…

Multiple lines of text in UILabel

Is there a way to have multiple lines of text in UILabel like in the UITextView or should I use the second one instead?

Thanks.

One just has to add the following code:

// Swift textLabel.lineBreakMode = .ByWordWrapping // or NSLineBreakMode.ByWordWrapping textLabel.numberOfLines = 0 // Objective-C…
