If you want to navigate through textfields (Next / Done Buttons)? In Cocoa for Mac OS X, you have the next responder chain, where you can ask the text field what control should have focus next. This is what makes tabbing between text fields work. But since iOS devices do not have a keyboard, only touch, this concept has not survived the transition to Cocoa Touch.
This can be easily done anyway, with two assumptions:
UITextFields are on the same parent view.Assuming this you can override textFieldShouldReturn: as this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | -(BOOL)textFieldShouldReturn:(UITextField*)textField { NSInteger nextTag = textField.tag + 1; // Try to find next responder UIResponder* nextResponder = [textField.superview viewWithTag:nextTag]; if (nextResponder) { // Found next responder, so set it. [nextResponder becomeFirstResponder]; } else { // Not found, so remove keyboard. [textField resignFirstResponder]; } return NO; // We do not want UITextField to insert line-breaks. } |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | func textFieldShouldReturn(_ textField: UITextField) -> Bool { let nextTag = textField.tag + 1 // Try to find next responder let nextResponder = textField.superview?.viewWithTag(nextTag) as UIResponder! if nextResponder != nil { // Found next responder, so set it nextResponder?.becomeFirstResponder() } else { // Not found, so remove keyboard textField.resignFirstResponder() } return false } |
