webview is not loading from table view cell - iphone

Question

Im adding a custom cell. Whenever someone presses the add button, a alert view pops up and they add a name of a website. once pressed saved, it gets saved in the table view cell under whatever name they choose. Then once someone clicks that cell i want it to load with http:// in my web view. the only problem is that its not loading. What am I doing wrong?
This is my table view controller
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellIdentifier = #"cellTwo";
UITableViewCell *cell = [myTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
if (indexPath.section == 0) {
cell.textLabel.text = [NSString stringWithFormat:#"%#",[tableData objectAtIndex:indexPath.row]];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"Index Selected,%d",indexPath.row);
MainTwoViewController *View = [self.storyboard instantiateViewControllerWithIdentifier:#"mainTwo"];
View.urlString = [[NSString alloc] initWithFormat:#"http://www.%#",tableData];
View.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
//Only do the following action if the user hits the ok button
if (buttonIndex == 1) {
NSString *tapTextField = [alertView textFieldAtIndex:0].text;
if (!tableData) {
tableData = [[NSMutableArray alloc]init];
}
[tableData insertObject:tapTextField atIndex:0];
[myTableView reloadData];
}
and of course i put this in the mainTwo view controller so it loads the urlString.
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:self.urlString]]];

Answer 1

You instantiate a view controller but do not show it.
Use storyboard segues instead and configure the new view controller in prepareForSegue.
Also, check the following:
If you are using storyboard, most likely you do not have to create cells in cellForRowAtIndexPath.
Also, simplify:
[NSString stringWithFormat#"%", string];
--> string
Finally, check the url that arrives at the new view controller before you load the request. Make sure sure the url is correct. Implement the UIWebViewDelegate methods to check for loading failures or unexpected return data.

i think your this code
View.urlString = [[NSString alloc] initWithFormat:#"http://www.%#",tableData];
should be like
View.urlString = [[NSString alloc] initWithFormat:#"http://www.%#",[tableData objectAtIndex:indexPath.row]];
at your didSelectRowAtIndexPath method, and it is also advisable that you use NSLog to check at which point you loose your data

Ok, I just identified your problem.
What you should do is put a tap gesture on the custom cell label first of all.
UITapGestureRecognizer *openURLTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(openURLTapped:)];
keypadDisableTapGestureRecognizer.numberOfTapsRequired = 1;
keypadDisableTapGestureRecognizer.numberOfTouchesRequired = 1;
[cell.textLabel addGestureRecognizer:openURLTapGestureRecognizer];
Now, in this openURLTapped, you can pass the url and open it.
-(void)openURLTapped:(UITapGestureRecognizer*)tap
{
// your code here
}
It will definitely resolve your issue.
