iPhone Bookmark UIWebView - Displaying Page Title and Storing URL - iphone

Question

I have a fully operational web browser application that stores bookmarked pages. When the bookmarks button is clicked, a listview of the stored websites is displayed. Instead of showing the URL, I would like the listview to display the title of the page, but I would like the UIWebView to go to the URL when the title is clicked.
I have included the code below. I have also put the properties in both header files, but can't get it to work. Please help!

You have to implement tableView:didSelectRowAtIndexPath:, roughly as follows:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *url=[bookmarks objectAtIndex:indexPath.row];
// open url here
}
A few considerations about your code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
explorerView.urlField.text = [bookmarks objectAtIndex:indexPath.row];
[explorerView textFieldShouldReturn:explorerView.urlField];
[self.parentViewController dismissModalViewControllerAnimated:true];
}
are you trying to replicate Mobile Safari?
you should probably avoid storing your bookmarks in the NSUserDefaults storage, and use a proper store.
you should not attempt to trigger a navigation action by simulating interaction events; the proper way to make a UIWebView (your underlying browser object) load a webpage is by using loadRequest:
The following code might work for you (I am relying on a lot of assumptions here):
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Get your url from the bookmarks object
NSString *urlString = [bookmarks objectAtIndex:indexPath.row];
// Convert to a URL object.
NSURL *url = [NSURL URLWithString:urlString];
// Create request
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[explorerView.webView loadRequest:requestObj];
// dismiss
[self.parentViewController dismissModalViewControllerAnimated:true];
}
