Thread 1:breakpoint 5.1: incompatible pointer types sending 'MWPhotoBrowser *' to parameter of type UIView

Question

I am trying to create a photo gallery with storyboards using MWPhotoBrowser. I have added a blue view to the first view but receive the error message

Thread 1:breakpoint 5.1:incompatible pointer types sending 'MWPhotoBrowser *' to parameter of type UIView.

Code:

In .h file:

#import <Foundation/Foundation.h>
#import "RESideMenu.h"

#import "MWPhotoBrowser.h"



@interface DEMOSevenViewController : UIViewController<MWPhotoBrowserDelegate>

@property (nonatomic, strong) NSMutableArray *photos;
@property (nonatomic, strong) NSMutableArray *thumbs;

@property (strong, nonatomic) UIView *container;

- (IBAction)showMenu;

@end

In .m file:

#import "DEMOSevenViewController.h"

@interface DEMOSevenViewController ()

@end

Answer 1

The problem is here, you are adding a ViewController and not a view where a View is expected.

[_container addSubview:browser];

Try:

[_container addSubview:browser.view];

Also, not entirely sure why you add it to a NavigationController and to _container depending on the rest of your code that might also cause problems, but the previous thing is what causes your error.
