IOS UISegmentedController 选择键盘

Question

是否可以使用 UISegmentedController 来确定用户可用的键盘类型？例如，我希望用户在激活一个段时使用数字键盘，而在激活另一段时使用默认键盘:

if (self.segmentController.selectedSegmentIndex == 1)
{
    NSLog(@"Seg1");
    [self.myTextField becomeFirstResponder];
    [self.myTextField setKeyboardType:UIKeyboardTypeNamePhonePad];
    //enter numbers

    [self resignFirstResponder];
    [self.myTextField reloadInputViews];
}
else if (self.segmentController.selectedSegmentIndex == 0)
{
    NSLog(@"seg0");
    [self.myTextField becomeFirstResponder];
    [self.myTextField setKeyboardType:UIKeyboardTypeDefault];
    // enter words

    [self resignFirstResponder];
    [self.myTextField reloadInputViews];
}

我确定我遗漏了什么。谁能帮忙？

谢谢

尝试在显示键盘之前设置类型。

改变:

[self.myTextField becomeFirstResponder];
[self.myTextField setKeyboardType:UIKeyboardTypeNamePhonePad];

收件人:

[self.myTextField setKeyboardType:UIKeyboardTypeNamePhonePad];
[self.myTextField becomeFirstResponder];
