UIPickerView values

[iph_s]

I want UIPicker to start from 2 (0, 1 to be not displayed)

self.tmpArray = [NSMutableArray arrayWithCapacity:10];

    for(int x = 2; x < 10; x++)
    {
        [self.tmpArray addObject:[NSNumber numberWithInt:x]];
    }

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {

    return [self.tmpArray count];
}

With the code above UIPicker shows 0,1,2,3 etc...

Are you loading the values for the pickerView in the pickerView delegate?

#pragma mark - 
#pragma mark Picker Delegate Methods

-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    return [self.tmpArray objectAtIndex:row];
}

Here is the delegate I use:

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
    NSString *title;
    title = [@"" stringByAppendingFormat:@"%d",row];
    
    return title;
}

I tried your suggest but I get:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber isEqualToString:]: unrecognized selector sent to instance 0x6a64b30'

It looks like your delegate is just putting the number of the row as the title. So, it will put the 0 and 1 in the picker.

You need to fill with the objects in your array.

Sorry, my fault. (I am still learning as well) I didnt realize it was a NSNumber in the array and not a NSString. Try this code instead.

-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{

    NSString *title = [NSString stringWithFormat:@"%@", [self.tmpArray objectAtIndex:row]];
    return title;
    
}
