预期类型

Question

I get an error that says 'Expected a Type' and I have no clue what that means. Here are the lines where the error is:

#pragma mark - Flipside View Controller

- (void)flipsideViewControllerDidFinish:(XYZFlipsideViewController*)controller <=== This    
is the line with the error
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        [self dismissViewControllerAnimated:YES completion:nil];
    } else {
        [self.flipsidePopoverController dismissPopoverAnimated:YES];
        self.flipsidePopoverController = nil;
    }
}

Answer 1

Generally, this message shows up when you have a structural typo in your file (that messes up the quotes or parenthesis balancing, etc...)

This has happened to me before and it was a header file that had a typo in it. Did you check XYZFlipsideViewController.h? Check for typos but also circular dependencies.

Answer 2

I had the same Problem. You should look at the elements which don't get highlighted correct, the type of the not highlighted element should be added to your class.

In my case, I had a problem with UIColor . This happens if UIKit.h is not included, so xCode doesn't know how to handle the used classes.

In your case, ** XYZFlipsideViewController.h** should be the problem. It might be possible you have also to include UIKit.h by adding

#import <UIKit/UIKit.h>

If this doesn't fix your problem have a look at other elements and there type and try to include the framework from iOS.
