Selecting a row in a UIPickerView dynamically?

Hook the button to an action method, then in your action method simply call the same selectRow:inComponent:animated: method, i. E (IBAction)button1Action { picker selectRow:20 inComponent:0 animated:YES; } And you hook up the button to that method in Interface Builder.

Yes, I did that. I even call 'reloadComponent' from the picker but it still does not work. I must be missing something here.

This is the code I use for 'button1' in my app. - (IBAction) goToRowTwenty { picker selectRow:20 inComponent:0 animated:YES; timerPickerView reloadComponent:0; } – Tuyen Nguyen Sep 10 '10 at 14:19.

You can put the same code that you have kept in viewDidLoad for selecting pickerRow on the event that get fires when button is clicked. -(void)button1clickevent{ //FUNCTION MUST GET FIRE WHEN BUttON! IS CLICKED picker selectRow:50 inComponent:0 animated:YES; } HAPPY iCODING...

Please check out whether your picker is really binded with the picker in xib.

Also make sure that picker is defined with "IBOutlet" as follows. And connect the picker's referencing outlet to this: @property (nonatomic, retain) IBOutlet UIPickerView *picker.

OK, now I recreate the project and retype the code: - (IBAction) goToRowTwenty { picker selectRow:20 inComponent:0 animated:YES; timerPickerView reloadComponent:0; } and it works, I really don't know what happened, but thank you guys for answering my question.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
