Accepted Answer

Following line is the issue

```
AVC.popoverPresentationController.sourceView = _webView;
```

You will have to put iOS8 condition in order `popoverPresentationController` is introduced for iOS 8 and later so you can not use it with iOS 7

For checking for iOS8 you can define a macro like found from here

```
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
```

And use it in following way.

```
     NSURL *linkURL = [NSURL URLWithString:_DetailModal1[4]];//article url
     NSMutableAttributedString *stringText = [[NSMutableAttributedString alloc]  initWithString:_DetailModal1[0]];//_DetailModal1[0] contain article title////
    [stringText addAttribute:NSLinkAttributeName value:linkURL range:NSMakeRange(0, stringText.length)];
    NSArray * itemsArray = @[[NSString stringWithFormat:@"%@",_DetailModal1[0]], [NSURL URLWithString:_DetailModal1[4]]];
    NSArray * applicationActivities = nil;
    UIActivityViewController * AVC = [[UIActivityViewController alloc] initWithActivityItems:itemsArray applicationActivities:applicationActivities];

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")){

AVC.popoverPresentationController.sourceView = _webView;
   }
   [self presentViewController:AVC animated:YES completion:nil];
```
