i am making an iPad application,
i want to load 2 webPage on single UIWebView one after another,
1st webpage should come when i load my application,and 2nd webpage should come on click of cell of tableView,
so,inside my didLoad method i am writing this (1st webpage),
NSString *urlAddress = #"http://www.google.com";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[webView loadRequest:requestObj];
it works fine..
but on the same page on same webview on click of cell of tableView i want to load another page,(2nd webpage)
i written code for loading 2nd webPage,
here is the code snippet for 2nd webPage,
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
DatabasesViewController *nextController=[[DatabasesViewController alloc]initWithNibName:#"DatabasesViewController" bundle:nil];
[self.navigationController pushViewController:nextController animated:YES];
[nextController changeProductText:[a objectAtIndex:indexPath.row]];
[nextController changeProductText1:[b objectAtIndex:indexPath.row]];
[nextController changeProductText2:[d objectAtIndex:indexPath.row]];
}
when i selects a cell inside tableView,
it navigates to new view, i don't want to navigate, i want to stay on same page what changes should i do in above function ?
in above function changeProductText,changeProductText1,changeProductText2, are three IBAction and a,b,d are my array names.
- (IBAction) changeProductText:(NSString *)str{
l1=#"http://ipad.appel.com/indexcharts.aspx?id=";
l2=str;
NSString *str1 = [l1 stringByAppendingString:l2];
NSURL *url2=[NSURL URLWithString:str1];
NSURLRequest *req2=[NSURLRequest requestWithURL:url2];
[webView loadRequest:req2];
}
when i click on cell of tableView webView is not displaying,
do i need to clear webpage or reload webpage something like that ?
Help Me Guys, Thanx in Advance !!
I think You can use the UISplitViewController for this issue.
EDIT : Now check out the code like this..
-(void)tableView:(UITableView *)tableView didSelectedRowAtIndexPath:
(NSIndexPath *)indexPath
{
NSString *urlString = [siteAddress objectAtIndex : indexPath.row];
detailViewController.webView.scalesPageToFit= yes;
NSUrl *url = [NSUrlRequest requestWithURL : url];
[detailViewController.webView loadRequest : request];
}
[self.navigationController pushViewController:nextController animated:YES];
This navigates you away from the page. It pushes a new view onto the navigation stack. Get rid of it if you don't want to do that.What is this a splitView?

I have a tabbed application, with a tab that contains a UIWebView and a second tab with a Table View Controller.
I'm trying to make it so that when I click on a row in the table it takes me to my other tab and loads a web page.
Here's my storyboard:
This is in my implementation for the web view:
-(void)loadAViewer:(NSURL*)viewerURL
{
NSURLRequest *requestObj = [NSURLRequest requestWithURL:viewerURL];
[sfnViewer loadRequest:requestObj];
}
And then in the table view controller:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//Get the URL from plist
...
//Generate url, pass it in and switch to web view tab
viewerURL = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#/viewer?username=%#&pw=%#&%#", web, loc, user, pass, params]];
ViewerFirstViewController *viewerWebView = [[ViewerFirstViewController alloc] init];
[viewerWebView loadAViewer:viewerURL];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[self.tabBarController setSelectedIndex:0];
}
Currently nothing happens. I'm taken to the other tab but with a blank UIWebView - no page loads but it doesn't crash either.
//Edit - Changes made based on answer from Steve
Based on this I've added
#property (strong, nonatomic) NSURL viewerUrl;
in my .h file for the UIWebView tab.
I've synthesized it in the .m and added this to my viewDidLoad method.
NSURLRequest *requestObj = [NSURLRequest requestWithURL:viewerURL];
[sfnViewer loadRequest:requestObj];
In the Table View Controller I'm now doing this.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//Get the URL from plist
...
//Generate url, pass it in and switch to web view tab
viewerURL = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#/viewer?username=%#&pw=%#&%#", web, loc, user, pass, params]];
ViewerFirstViewController *viewerWebView = [[ViewerFirstViewController alloc] init];
[viewerWebView setViewerUrl:viewerURL];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[self.tabBarController setSelectedIndex:0];
}
Still to no avail.
It's probably not loading because when you call loadAViewer: the view itself hasn't been loaded yet so the sfnViewer outlet won't be hooked up to the UIWebView in your storyboard.
You can confirm this by checking if sfnViewer is nil in loadAViewer:.
If this is the case you will have to define an NSURL property on the ViewerFirstViewController and assign to that instead of calling loadAViewer:. Then in the viewWillAppear: method you should load the URL into sfnViewer.
However this will result in the web view being reloaded each time the tab is accessed, you could avoid this by checking if viewerURL is different from the URL currently in use in the web view: [sfnViewer.request.URL isEqual:self.viewerURL], if it is the same then don't create/load the request.
I'm trying create a subclass of UIActivity to add a custom button to a UIActivityViewController. I want this custom button to be able to open a link without leaving the application. I've found numerous solutions that allow for opening things in safari, but I can't figure out if it is possible to just open a UIWebview inside my app (Modal view perhaps?).
I've tried creating a `UIWebview in the delegate method to handle the click, but since this isn't a viewcontroller I can't add it to the view hierarchy.
- (void)prepareWithActivityItems:(NSArray *)activityItems{
UIWebView *webView=[[UIWebView alloc] initWithFrame:CGRectMake(0,0,320,480)];
NSURLRequest *urlRequest;
NSURL *urlforWebView;
urlforWebView=[NSURL URLWithString:#"http://www.google.com"];
urlRequest=[NSURLRequest requestWithURL:urlforWebView];
[webView loadRequest:urlRequest];
}
// example:Need to add your webview to your mainview first
UIWebView *webView = [[UIWebView alloc] init];
[webView setFrame:CGRectMake(0, 0, 320, 460)];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://google.com"]]];
[[self view] addSubview:webView];
I believe this project implements just what you would like to do but it opens in safari: https://github.com/davbeck/TUSafariActivity Good for starting point.
The activity itself cannot open the view as it is not connected to the controller view hierarchy. You need some way to tell the host controller that the user has selected your activity. The easiest way to do this is through notifications:
The view controller registers for notifications with a given identifier.
The activity posts this notification if performed.
The notification is processed by the activity in the handler method and it opens the web view.
Don't forget to unregister the view controller from the notification center if the controller is being removed from the navigation stack.
There are lots of examples for using notifications, like this Send and receive messages through NSNotificationCenter in Objective-C?
Try this
UIPlainViewController here is just a custom UIViewController with a WebView added to it. Implement (UIViewController *)activityViewController in your derived UIActivity class as such:
(UIViewController *)activityViewController {
NSString *page = #"some url";
NSURL *url = [[NSURL alloc] initWithString:page];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
[((UIPlainViewController*)self.plainViewController).webView loadRequest:request];
return self.plainViewController;
}
I have an app. In this on the click of an Upload button a UITableView appears inside a UIPopOverController with a few entries. On clicking on any of these entries, a corresponding site should open in the wUIWebView of my UIDetailView of SplitView app.
I am using the following lines of code ::
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here. Create and push another view controller.
hUrl = [kk objectAtIndex:indexPath.row];
hUrl = [Url stringByReplacingOccurrencesOfString:#" " withString:#"_"];
NSString *hisPage= [[NSUserDefaults standardUserDefaults] stringForKey:#"url_preference"];
Page = [hisPage stringByAppendingString:#"/index.php/"];
Page = [hisPage stringByAppendingString:hUrl];
NSURL *Url = [NSURL URLWithString:Page];
NSLog(#"%#", Url);
NSURLRequest *request = [NSURLRequest requestWithURL:Url];
self.detailViewController.webView.scalesPageToFit = YES;
[self.detailViewController.webView loadRequest:request];
}
The UITableView appears inside a UIPopoverController. However, I am unable to load the corresponding webPage. Can someone help me to sort this out ?? Thanks and regards.
Per your answer to my comment, the proper procedure to follow in this scenario is as follow:
Implement a delegate method protocol for your popOverController instant.
In didSelectRowAtIndexPath, call the delegate method back to the parent view controller (where your Upload button located). And passing back the Url string as a parameter.
From the parent view controller, dismiss the popover and using the passed back Url to prepare your detailViewController and then push it onto display stack.
An example of delegate method can be found in this SO .
My webpage will not load it shows nothing I have 3 viewcontrollers in firstviewcontroller you click the button which loads the next page thirdviewcontroller up to this point all is good but the webpage doesnt load
code from firstviewcontroller
-(IBAction)moveToViewSiteView:(id)sender{
self.third = [[[SecondViewController alloc]initWithNibName:#"ThirdViewController" bundle:nil]autorelease];
[self.navigationController pushViewController:self.third animated:YES];
}
code in thirdviewcontroller
- (void)viewDidLoad {
NSString *urlAddress=#"http://www.apple.com/";
NSURL *url=[NSURL URLWithString:urlAddress];
NSURLRequest *requestObj= [NSURLRequest requestWithURL:url];
[self.cscsPage loadRequest:requestObj];
[super viewDidLoad];
}
the uiwebview i have called webview in the document window in ib if i drag from files owner to the webview then when i run it the app crashes.
hope all is clear
thanks
Move [super viewDidLoad]; to the top of viewDidLoad method. You should invoke the super class implementation of it first.
im making an application where i have to load my database from html file which is in my resource folder. i have a table view and when i click on a certain cell it will open html file based on that click. can any one help me how to do this. thanks
// create a web view in "cellForRowAtIndexPath"
UIWebView *wv = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,320,480)];
[wv loadHTMLString: << your html >> baseURL: nil];
wv.delegate = self;
// implement the webView delegate
- (void) webViewDidFinishLoad:(UIWebView *)webView {
[self.view addSubView:webView]; // or push onto the naviation controller
}
I think when you 'didSelectCellAtIndex' in the table view will open a new view controller with the webview. And you have also mapping of each cell with the corresponding html file name. Then in the viewDidLoad method of your next VC, you can use this code, while webView is the outlet pointing to your UIWebView. And htmlFileName is the html file's name.
[webView loadRequest:[NSURLRequest requestWithURL:
[NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:htmlFileName
ofType:#"html"]
isDirectory:NO] ] ];
