Multiple PDFs in different tabs - ios

Question

I have a Tabbar iOS application with three tabs. I have each tab set up to be a UIWebView. I want each web view to display a different PDF. How do I assign, through code, each webview to its corresponding pdf?

It will look something like this in your AppDelegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
WebViewController *webViewController1 = [[WebViewController alloc] initWithPDFAtURL:#"urlToPDF1"];
WebViewController *webViewController2 = [[WebViewController alloc] initWithPDFAtURL:#"urlToPDF2"];
WebViewController *webViewController3 = [[WebViewController alloc] initWithPDFAtURL:#"urlToPDF3"];
UITabBarController *tabBarController = [[UITabBarController alloc] init];
[tabBarController setViewControllers:[NSArray arrayWithObjects:webViewController1, webViewController2, webViewController3, nil]];
self.window.rootViewController = tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
You will need to have a view controller that holds the UIWebView, and could look something like:
// WebViewController.h
#interface WebViewController : UIViewController
#end
// WebViewController.m
#interface WebViewController ()
#property (nonatomic, strong) NSURL *_pdfURL;
#end
#implementation WebViewController
#synthesize _pdfURL;
- (id)initWithPDFAtURL:(NSURL *)url {
self = [super init];
if (self) {
_pdfURL = url;
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Load the PDF into a UIWebView
}
