How to use UIPickerView

Question

I have been newly using UIPickerView, while showing UIPickerView do I need to hide all other controls in the same view, because I am getting issue like this. please see the image below

button behind is showing front. how to avoid this issue. Any idea?

Where are you creating your picker and where are you adding it to the view? And are you using the picker as input for a `UITextField`? You might want to set the picker as `UITextField`'s `inputView` in this case. — Michael Ochs, Oct 19 '12 at 11:20

No its not working, I thing while adding the button I had added over the picker view I guess. I have to check – Newbee Oct 19 '12 at 11:28
yes and where you add button?? and if you add button any where but if you write above method bringToSubview then your pickerview must show as a superview , mate.. – Paras Joshi Oct 19 '12 at 11:30

Hi i think you have to set the frame for picker view. Below code is for uipickerview, plz modify as you wish.

-(IBAction)pickButtonpressed:(id)sender

{

UIActionSheet *asheet = [[UIActionSheet alloc] initWithTitle:@"Select Distance" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Select", nil];

[asheet setTag:200];

UIPickerView *statePicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 40, 0, 0)];

statePicker.delegate=self;

statePicker.showsSelectionIndicator = YES;

[statePicker setTag:11];

[asheet addSubview:statePicker];

[asheet showInView:[self.view superview]]; //note: in most cases this would be just self.view, but because I was doing this in a tabBar Application, I use the superview.

[asheet setBounds:CGRectMake(0,0,320, 700)];

[asheet setFrame:CGRectMake(0, 117, 320, 383)];

NSArray *subviews = [asheet subviews];

[[subviews objectAtIndex:1] setFrame:CGRectMake(20, 266, 280, 46)]; 

[[subviews objectAtIndex:2] setFrame:CGRectMake(20, 317, 280, 46)];

}
