Question

I have 10 different pages built into a slider control in my app, these pages are setup using storyboards.

The only difference on each page is a different web view to display rich text and a different image as a background are used.

Is it possible for me to have one view controller for all 10 pages and setup some flags in the constructor which would be executed on every page when its loaded to tell it what image and web view to show? If so what would this look like?

Thanks,

Lewis.

You can create subclass of UIViewController, for example MyViewController.
And then replace your .h file with:

#import <UIKit/UIKit.h>

@interface MyViewController : UIViewController

@property (nonatomic, strong) UIWebView *myWebView;
@property (nonatomic, strong) UIImageView *myImageView;

- (id)initWithURLString:(NSString *)urlString image:(NSString *)imageName;

@end

And your .m file with:

#import "MyViewController.h"

@interface MyViewController ()

@end

@implementation MyViewController

@synthesize myWebView = _myWebView;
@synthesize myImageView = _myImageView;

- (id)initWithURLString:(NSString *)urlString image:(NSString *)imageName
{
    self = [super init];

    if (self) {
        NSURL *url = [NSURL URLWithString:urlString];
        NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];

        _myWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 400)];
        [_myWebView loadRequest:urlRequest];

        _myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
        _myImageView.frame = CGRectMake(0, 400, 60, 60);
    }

    return self;
}

@end

And then just create an instances of your UIViewController subclass:

MyViewController *vCon = [[MyViewController alloc] initWithURLString:someURLString image:imageName];
