Change text of “Return” keyboard button

问题

How can I change the standard text of the \"Return\" button to something else?

I want it to be \"Add\".

回答1:

Unfortunately, you can change "Return" into only one of these predefined labels with the returnKeyType property:

• Return (default)
• Go
• Google
• Join
• Next
• Route
• Search
• Send
• Yahoo
• Done
• Emergency Call
• Continue (as of iOS 9)

So maybe you should choose "Next" if a data entry kind of activity is what you're after.

You can use this simple way: [textField setReturnKeyType:UIReturnKeyNext]; or [textField setReturnKeyType:UIReturnKeyGo]; instead of "Add" button.

Other, you create a programmatically keyboard with buttons which you want.

iOS 9 now supports Send button. This is the following swift code

self.liveChatMessage.returnKeyType = .Send

Objective C:

[self.liveChatMessage setReturnKeyType: UIReturnKeyTypeSend];
