TableViewCell - DetailtextLabel to call WebViewController - ios

Question

I'm working on RSS app, and in my last view (tableView), i would like to use the cell.detailTextlabel to call the WebViewController and open the related article in Safari.
Actually I don't know if this is the best way, but i need to have this "Read More" to open the whole article.
In the end of my third section (attached image), i inserted the "Read More" - detailTextLabel.text = #"Read More" - but i don't know how to link to the WebViewController and to pass the correct URL.
Searching on the net, i found this example to open in Safari:
**WebViewController.h**
#import <UIKit/UIKit.h>
#interface WebViewController : UIViewController
#property (strong, nonatomic) NSString *url;
#property (strong, nonatomic) UIWebView *webView;
- (id)initWithURL:(NSString *)postURL title:(NSString *)postTitle;
#end
**WebViewController.m**
#implementation WebViewController
#synthesize url = _url, webView = _webView;
- (id)initWithURL:(NSString *)postURL title:(NSString *)postTitle
{
self = [super init];
if (self) {
_url = postURL;
self.title = postTitle;
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.url = [self.url stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSURL *newURL = [NSURL URLWithString:[self.url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
// Do any additional setup after loading the view.
_webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[self.view addSubview:self.webView];
[self.webView loadRequest:[NSURLRequest requestWithURL:newURL]];
}
- (void)viewDidAppear:(BOOL)animated {
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#end
Thanks in advance.

You can add a custom UIButton instance to the tableview cell and tag it with indexPath.row or indexPath.section according to your structure. On the button action, get the sender's tag and get the exact URL out of your dataSource Array and call WenViewController with that URL.
You can add the button in cell's contentView with desired frame. For eg
CGRect cellFrame = cell.contentView.frame;
UIButton *readMore = [[UIButton alloc]
initWithFrame:CGRectMake(cellFrame.origin.x+20, cellFrame.origin.y+cellFrame.size.height - yourButtonHeight -10, yourButtonWidth, yourButtonHeight)];
[readMore addTarget:self action:#selector(openWebView:) forControlEvents:UIControlEventTouchUpInside];
[readMore setTitle:#"Read More" forState:UIControlStateNormal];
[readMore setTag:indexPath.row];
[cell.contentView addSubview:readMore];
// Release readMore button if not using ARC
And then make the method
-(void)openWebView:(UIButton*)sender{
int tag = sender.tag;
// Get URL from array using tag as index
}
