There is the delegate method of UIPickerView. #pragma mark - PickerView Delegates
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
//=====================================================================================
//Customize Number of rows in Component
//=====================================================================================
- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
if([genreList count] != 0)
{
return [genreList count];
}
else
{
return 0;
}
}
//=====================================================================================
//Set title For Row
//=====================================================================================
- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row1 forComponent:(NSInteger)component {
if([genreList count] != 0)
{
return [genreList objectAtIndex:row1];
}
else
{
return nil;
}
//return 4;
}
