How do I get the text from UITextField into an NSString?

问题

I've tried various methods, which all give me warnings. Such as userName = [NSString stringWithFormat:@"%@", [yournamefield stringValue]]; which just gives me a warning of

'UITextField' may not respond to '-stringValue'

How do i do this?

回答1:

Get the text inside the text field using the text property

NSString *name = yourNameField.text;

回答2:

Use the text property of UITextField:

NSString *userName = yourNameField.text;

回答3:

How about:

userName = [NSString stringWithFormat:@"%@", yournamefield.text];

回答4:

Two ways. It is a property and any property value can be accessed like this -

• yournamefield.text
• [yournamefield text]
