ios – Xcode：通过Action Sheet共享内容

它不是在UIActionSheet它是UIActivityController是iOS中的默认功能

客观-C

- (void)presentActivityController:(UIActivityViewController *)controller {

    // for iPad: make the presentation a Popover
    controller.modalPresentationStyle = UIModalPresentationPopover;
    [self presentViewController:controller animated:YES completion:nil];

    UIPopoverPresentationController *popController = [controller popoverPresentationController];
    popController.permittedArrowDirections = UIPopoverArrowDirectionAny;
    popController.barButtonItem = self.navigationItem.leftBarButtonItem;

    // access the completion handler
    controller.completionWithItemsHandler = ^(NSString *activityType,BOOL completed,NSArray *returnedItems,NSError *error){
        // react to the completion
        if (completed) {
            // user shared an item
            NSLog(@"We used activity type%@",activityType);
        } else {
            // user cancelled
            NSLog(@"We didn't want to share anything after all.");
        }

        if (error) {
            NSLog(@"An Error occured: %@,%@",error.localizedDescription,error.localizedFailureReason);
        }
    };
}

迅速

let shareText = "Hello,world!"

if let image = UIImage(named: "myImage") {
    let vc = UIActivityViewController(activityItems: [shareText,image],applicationActivities: [])
    presentViewController(vc,animated: true,completion: nil)
}
