Hi,

How chould I get the text/NSString of selected rows ?

(void)pickerViewController:(RMPickerViewController )vc didSelectRows:(NSArray )selectedRows

Thanks

selectedRows is an array containing NSNumbers. selectedRows[0] contains the selected row in component 0 of your picker view. selectedRows[1] contains the selected row in component 1 of your picker view and so on.

Therefore, you can get the title of the selected row in a certain component just like you calculated the title in

(NSString )pickerView:(UIPickerView )pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

(UIView )pickerView:(UIPickerView )pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view

Hope this helps :)

Hmmm I think I didn't get the point since I tried selectedRows[0] it also shows number

CooperRS commented 10 years ago

Right, selectedRows[0] contains the selected row in component 0. Knowing the index of the selected row also means that you know the title, as in

(NSString )pickerView:(UIPickerView )pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

(UIView )pickerView:(UIPickerView )pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view

you also need a title for a certain index. You just need to re-use that knowledge.
