iOS UITextField禁止键盘弹出，同时又实现代理方法的实现方式！

#pragma mark 实现textField代理中的方法-(void)textFieldDidBeginEditing:(UITextField*)textField{    if (textField.tag == 70) {        [textField resignFirstResponder];        _picker = [[PickerChoiceView alloc]initWithFrame:self.view.bounds];        _picker.delegate = self;        _picker.strType = @"注册日期";        _picker.arrayType = DeteArray;        [self.view addSubview:_picker];    }}
