Question

I have incomplete implementation warning on my implementation page (the same functions is on the right.m file):

left.m file

#import "left.h"
#import "shareL.h"

@interface left ()

@end

@implementation left    // Incomplete implementation

- (IBAction)shareL {

    shareL *screen = [[shareL alloc] initWithNibName:nil bundle :nil];
    screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self presentModalViewController:screen animated:YES];

}


- (IBAction)backButton {

    [self dismissModalViewControllerAnimated:YES];

}


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

Why is incomplete implementation? On the right side I have same functions and everything it’s OK.

By opening up the incomplete implementation warning you can find out exactly what method(s) you may be missing implementations of. Below is a screenshot that illustrates what the issue may be. In my case I’d commented out a method called fadeAction
