How to set data for UIPickerView?

Implement the UIPickerViewDataSource methods :

– numberOfComponentsInPickerView:
– pickerView:numberOfRowsInComponent:

      

        
        
        
      

    

and UIPickerViewDelegate :

– pickerView:titleForRow:forComponent:

      

        
        
        
      

    

Don't forget to set properties:

UIPickerView * myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];
myPickerView.delegate = self;
myPickerView.dataSource = self;
[self.view addSubview:myPickerView];

      

        
        
        
      

    

And in the .h file, don't forget to put:

<UIPickerViewDelegate, UIPickerViewDataSource>

      

        
        
        
      

    

I usually use NSMutableArray

filled with strings to fill in the data. Hope it helps!
