Description
Basically I need to know how a webview knows what kind of file extension is being tapped, (png, zip, etc) and then push another view controller. So far I have this.
UPDATE 6/13 - I have updated my code per what Hunter has suggested, yet it still only opens the png, instead of pushing the vc.
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
NSURL *theRessourcesURL = [request URL];
NSString *fileExtension = [theRessourcesURL pathExtension];
if ([fileExtension isEqualToString:@"png"]) {
MYViewController *vc = [[MYViewController alloc] init];
[dlvc downloadURL:theRessourcesURL userInfo:nil];
[self.navigationController pushViewController:vc animated:YES];
vc.delegate = self;
}
else{}
}
return YES;
}
I have tried this before without the file extension code and it will push another view just fine.
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
NSURL *theRessourcesURL = [request URL];
DetailViewController *vc = [[DetailViewController alloc] init];
[vc downloadURL:theRessourcesURL userInfo:nil];
[self.navigationController pushViewController:vc animated:YES];
vc.delegate = self;
}
return YES;
}
I also tried to use this as a starter base without success, as I don't use interface builder, so I don't know if IBActions can be used (if they can I dont know how to implement them properly). http://stackoverflow.com/questions/7377565/how-to-download-files-from-uiwebview-and-open-again
Any help would be appreciated.
Explanation & Answer
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[DemoFirstViewController alloc] initWithNibName:@"DemoFirstViewController" bundle:nil];
UIViewController *viewController2 = [[DemoSecondViewController alloc] initWithNibName:@"DemoSecondViewController" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = @[viewController1, viewController2];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = navigationController;
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[DemoFirstViewController alloc] initWithNibName:@"DemoFirstViewController" bundle:nil];
// here I create a Navigation Controller and set its root view controller to viewController1
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UIViewController *viewController2 = [[DemoSecondViewController alloc] initWithNibName:@"DemoSecondViewController" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
// updated this line to show the navController1 (which contains viewController1)
self.tabBarController.viewControllers = @[navController1, viewController2];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
