在自定义单元格动态UITableView内的Tap文本字段上显示UiPickView

Question

我需要在Tableview中显示一个自定义的uidropdown，但是在iOS中使用UIPickerView而不是dropdown.Table视图是动态生成的，取决于服务器的输入数据，它对于UiTextFields很好用，但是我不能使用它显示UIPickerView.Plese指导我如何解决此问题。谢谢。

Answer 1

Write delegate method of UItextFiled

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
   [textField resignFirstResponder];
   [self setupPicker];        
}

and call setupPicker method

-(void)setupPicker
{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Set alarm time" message:@"\n\n\n\n\n\n\n\n" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil];
    [alert show];
    alert.bounds = CGRectMake(0, 10, 284, 279);
    if(!self.datePicker)
    {
        self.Picker = [[UIPickerView alloc] init];
        self.Picker.frame = CGRectMake(20, 45.0, 240.0, 150.0);
        self.picker.delegate = self;
        self.picker.dataSource = self;
    }
    [alert addSubview:self.Picker];
}

Above code for display picker view when you click on UITextFiled and UIPickerView display on AlertView.
