奇怪的UIPickerView in IOS7

Question

开始开发与IOS 7相匹配，但我对UIPickerView's在IOS 7 (Only in IOS7)中的奇怪行为一无所知。正如他们在这里所指出的我也面临一个问题。当我点击pickerView时，键盘就会被打开。我不能就此辞职。

，我尝试了以下所有东西--

[sender resignFirstResponder];
[self dismissKeyboard];
[self.view endEditing:YES];

我的守则：

- (IBAction)selectCountry:(UIControl *)sender {

    UITextField *txtfld = (UITextField*)sender;
    NSLog(@"selectCountry Picker Called:%d ",txtfld.tag);

    [self dismissKeyboard];
    [self.view endEditing:YES];

    [sender resignFirstResponder];

        ActionStringDoneBlock done = ^(ActionSheetStringPicker *picker, NSInteger selectedIndex, id selectedValue) {
            if ([billingCountry respondsToSelector:@selector(setText:)]) {
                [billingCountry performSelector:@selector(setText:) withObject:selectedValue];
                selectedBillingCountry = selectedValue;

                        }

            [self resetShippingServicesControl];
            [self resetProvinceState];
            [self loadViewAsperCountry];
                               };


        ActionStringCancelBlock cancel = ^(ActionSheetStringPicker *picker) {
            NSLog(@"selectCountry Picker Cancelled");
            [self dismissKeyboard];
            [self.view endEditing:YES];
            [sender resignFirstResponder];
        };
        NSArray *countryA = [NSArray arrayWithArray:[self getCountryList]];
        [ActionSheetStringPicker showPickerWithTitle:@"Select Country" rows:countryA initialSelection:0 doneBlock:done cancelBlock:cancel origin:sender];


}

但是，它仍然是：请帮我找出解决办法。我需要为IOS7用户重新设计吗？提前谢谢极客们。

您的问题似乎是关于UIActionSheet，而不是UIPickerView。

您不应该向UIActionSheet添加子视图，如其文件中所述

UIActionSheet不是为子类设计的，也不应该将视图添加到它的层次结构中。如果您需要提供比UIActionSheet API提供的更多定制功能的工作表，您可以创建自己的工作表，并使用presentViewController:动画:completion: more显示它。
