UIPickerView: unrecognized selector sent to instance - ios5

Question

I'm building a form for inputting data into a web database. Everything is going great, but I have to have multiple pickers with multiple sets of data. I'm trying to set up a class that I can instantiate and set as the data source and delegate to the pickers that I pull up, and had it to a point, but went with another method. Now I can't get it to load the data, giving me this error:
'NSInvalidArgumentException', reason: '-[__NSArrayI numberOfComponentsInPickerView:]: unrecognized selector sent to instance 0x6c9c970'
So here is my code for the picker class:
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
return myArray.count;
}
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
return [myArray objectAtIndex:row];
}
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
rowInt=row;
}
-(IBAction)setMyArray:(NSMutableArray *)incomingArray{
myArray = incomingArray;
}
And here is the actual picker itself.
PickerViewLoader *source = [[PickerViewLoader alloc]init];
myarray =[[NSMutableArray alloc] initWithObjects:#"a", #"b", #"c", #"d", #"e", nil];
[source setMyArray:myarray];
pickerAction=[[UIActionSheet alloc]initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
[pickerAction setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
UIPickerView *carrierPicker =[[UIPickerView alloc]initWithFrame:pickerFrame];
carrierPicker.showsSelectionIndicator=YES;
carrierPicker.dataSource=source;
carrierPicker.delegate=source;
[pickerAction addSubview:carrierPicker];
UISegmentedControl *closeButton=[[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObject:#"OK"] ];
closeButton.momentary = YES;
closeButton.frame=CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle =UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:#selector(closePicker) forControlEvents:UIControlEventValueChanged];
[pickerAction addSubview:closeButton];
[pickerAction showInView:self.view];
[pickerAction setBounds:CGRectMake(0, 0, 320, 464)];
Thoughts?

I fixed this by running local variables and loading them all using the same class. I pulled these variables in using XML and made them on load of the picker.
