Custom Uitextview placeholder (placeholder text)

We know that in iOS development, the control Uitextfield has a placeholder property, Uitextfield and Uitextview use the method basically similar, there are two small differences: 1. Uitextfield single-line input, while Uitextview can enter multiple lines. 2.UITextField has a placeholder attribute, and Uitextview does not. As for the two agent method, the principle is basically similar, but the method name slightly different.

How to add a placeholder function for Uitextview, in fact, the method is very simple, three steps can be achieved:

1. When creating a TextView, assign its Text property

namely Textview.text = @ "Want to say words";

2. In the agent method to begin editing, do the following

-(void) textviewdidbeginediting: (Uitextview *) TextView {

if ([Textview.text isequaltostring:@ "want to say"]) {

Textview.text = @ "";

}

}

3. In the proxy method that ends the edit, do the following

-(void) textviewdidendediting: (Uitextview *) TextView {

if (textview.text.length<1) {

Textview.text = @ "words to say";

}

}
