来自链接的代码snippit:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    if (textField == field1TextField) {
        [textField resignFirstResponder];
        [field2TextField becomeFirstResponder];
    } 
    else if (textField == field2TextField) {
        [textField resignFirstResponder];
        [field3TextField becomeFirstResponder];
    }
    else if (textField == field3TextField) {
        [textField resignFirstResponder];
    }
    return YES;
}
