如何处理名称为“的键盘按钮”；“完成”；在ios中

现在我有了一个文本字段

当我输入一些单词时，键盘就会出现

当我按下键盘“完成”时，键盘将消失。（我已经完成了这个功能）

但是接下来呢,

我想在用户按下“完成”按钮时使用core data framework插入数据

那么，如何解决这个问题呢

我知道如何使用核心数据插入数据，因此您无需告诉我如何插入数据

我正在使用此代码来删除键盘

-(BOOL)textFieldShouldReturn:(UITextField *)theTextField {
  [txtName resignFirstResponder];
  return YES;
}

谢谢大家

在示例代码中，我有3个UITextField。您可以在到达最后一个字段后处理更新

// I the tag property to indicate which field I am on during runtime
enum {
    Line1Tag = 50,
    Line2Tag,
    Line3Tag
};

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    // The user has pressed the "Return Key"
    // Which I have set to "Next" for first two lines
    // and "Done" for the last line, so jump to the next text field
    NSLog(@"\"Return\" key pressed.");

    // based on which text field we are in jump to the next
    if (textField.tag == Line3Tag)
        // We have reach the last line so hide keyboard
        [textField resignFirstResponder];

        // this is where you can perform Core Data updates if you like

    else {
        int nextTag = textField.tag + 1;
        UIView *nextField = [self.view viewWithTag:nextTag];
        [nextField becomeFirstResponder];

        // Once the next text field is the first responder
        // I need to make sure the user can see it
        [self makeActiveTextFieldVisible];
    }
    return NO;
}
