libc++abi.dylib: terminating with uncaught exception of type NSException

这是我的代码，如果有人可以帮助我

- (IBAction)compartir:(id)sender{
    NSLog(@"Sharing2");

    NSString *text = self.story.title;
    NSURL *url = self.story.url;
    UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:self.story.thumb]];

    UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:@[text, url, image] applicationActivities:nil];

    if ([controller respondsToSelector:@selector(popoverPresentationController)]) {
        controller.popoverPresentationController.barButtonItem = (UIBarButtonItem *)sender;
    }

    [self presentViewController:controller animated:YES completion:nil];
}

如果我工作，

在iPhone上使用相同的代码

这是iPhone中的代码：

- (IBAction)share:(id)sender {
    NSLog(@"Sharing");

    NSString *text = self.story.title;
    NSURL *url = self.story.url;
    UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:self.story.thumb]];

    UIActivityViewController *controller =
    [[UIActivityViewController alloc]
     initWithActivityItems:@[text, url, image]
     applicationActivities:nil];

    [self presentViewController:controller animated:YES completion:nil];
}

Answer 1

由于sender实际上是UIBarButtonItem，因此您无法将sender强制转换为UIButton。

更改行：

controller.popoverPresentationController.barButtonItem = (UIBarButtonItem *)sender;

为：

controller.popoverPresentationController.sourceView = sender;
