Getting the text from a label inside of a UIView when UIView is clicked

I have a custom UIView class called TabView. Each TabView has 2 labels in it as well as a few other elements. I add these labels and to the TabView using interface builder. Inside of my view controller that has the TabViews as subviews I attach a touch event to each of the TabViews using the following method

- (void)viewDidLoad
{
    [super viewDidLoad];
    for (UIView *tabView in self.view.subviews) {
        if([tabView isKindOfClass:[DeviceTabView class]]){
            [self addGestureRecogniser:tabView];
        }
    }
}

-(void)addGestureRecogniser:(UIView *)touchView{

    UITapGestureRecognizer *singleTap=[[UITapGestureRecognizer alloc]initWithTarget:self
                                                                             action:@selector(segueToDeviceUpload:)];
    [touchView addGestureRecognizer:singleTap];
}

I need to be able to get the two label values from the clicked UIView so that I can pass it to the following view controller. I know how to pass values around between ViewControllers, just unsure how to grab the labels from the selected TabView. Thanks for any guidance!

You get the selected tabView from the UIGestureRecognizer passed to segueToDeviceUpload: via gestureRecognizer.view. I'd suggest to assign some tag to each label so you can get them from the tabView via viewWithTag:

Everything at once:

-(void)segueToDeviceUpload:(UITapGestureRecognizer*)sender{
    UIView *tappedView = sender.view;
    UILabel *label1 = (UILabel*)[tappedView viewWithTag:1];
    UILabel *label2 = (UILabel*)[tappedView viewWithTag:2];
}

You could get the text by iterating through the view's subviews, similarly to what you're already doing above:

- (void)segueToDeviceUpload:(UIGestureRecognizer *)gestureRecognizer {
    for (UIView *view in gestureRecognizer.view.subviews) {
        if([view isKindOfClass:[UILabel class]]){
            NSLog(@"One piece of text: %@",((UILabel *)view).text);
        }
    }
}

You could use tags to differentiate between each label.
