Crash on integerValue

[pronebird]

I see a crash on selectedRow = [[_pickerViewArray objectAtIndex:0] integerValue]; but I don't understand why pickerView tries to take an integerValue from objects array that I pass via +(void)showPickerViewInView:(UIView *)view withObjects:(NSArray *)objects withOptions:(NSDictionary *)options objectToStringConverter:(NSString *(^)(id))converter completion:(void (^)(id))completion

You must set selectedObject property as in the example.

NSArray *strings = @[@"This", @"is", @"just", @"an array", @"of strings."];
[MMPickerView showPickerViewInView:self.view
withStrings:strings
withOptions:@{selectedObject:_selectedString}
completion:^(NSString *selectedString) {

                        _label.text = selectedString;
                        _selectedString = selectedString;

}];
