Question

我很清楚如何与the iOS sharing activity分享链接...但我想在网址中为不同类型的共享定制跟踪，始终使用相同的标准......示例如下。 ..

Twitter的：

http://www.example.com?utm_source=TWITTER&utm_medium=social&utm_campaign=socialbuttons&utm_content=app_android

Facebook的：

http://www.example.com?utm_source=FACEBOOK&utm_medium=social&utm_campaign=socialbuttons&utm_content=app_android

等等...

有可能吗？我该怎么办？

我通过添加自定义UIActivityItemProvider：

在Objective-C中解决了这个问题

#import "CustomUiActivityItemProvider.h"

@implementation CustomUiActivityItemProvider

- (id)initWithText:(NSString *)text{

    if ((self = [super initWithPlaceholderItem:text])) {
        self.text = text ?: @"";
        self.url = @"";
    }
    return self;
}

- (id)item {
    NSString *activityType = self.activityType;

    if ([self.placeholderItem isKindOfClass:[NSString class]]) {

        if ([self.activityType isEqualToString:UIActivityTypePostToFacebook]) {
            self.url = [[NSString alloc] initWithFormat:@"%@&utm_source=facebook", self.text];
        } else if ([activityType isEqualToString:UIActivityTypePostToTwitter]) {
            self.url = [[NSString alloc] initWithFormat:@"%@&utm_source=twitter", self.text];
        } else if ([activityType isEqualToString:UIActivityTypeMessage]) {
            self.url = [[NSString alloc] initWithFormat:@"%@&utm_source=message", self.text];
        } else if([activityType isEqualToString:UIActivityTypeMail]){
            self.url = [[NSString alloc] initWithFormat:@"%@&utm_source=email", self.text];
        } else if ([activityType isEqualToString:UIActivityTypePostToWeibo]){
            self.url = [[NSString alloc] initWithFormat:@"%@&utm_source=weibo", self.text];
        }else{
            self.url = [[NSString alloc] initWithFormat:@"%@&utm_source=other", self.text];
        }

        return self.url;
    }

    return self.placeholderItem;
}

@end

并像这样使用它：

CustomUiActivityItemProvider *customProvider = [[CustomUiActivityItemProvider alloc] initWithText:urlString];


UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:@[customProvider]
                                                                         applicationActivities:nil];
activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll];
activityVC.completionHandler = ^(NSString *activityType, BOOL completed) {
 // CODE.... 
}
   [self presentViewController:activityVC animated:YES completion:nil];

为此，我们将使用UIActivityItemSource作为UIActivityViewController的数据提供者。文档说明如下。

实现此协议时，您的对象将成为数据提供者，为视图控制器提供对项目的访问权。

详情请参阅此documentation。

按如下方式创建NSObject课程，并在UIViewController课程后添加

class shareDifferentUrl: NSObject, UIActivityItemSource {
@objc func activityViewControllerPlaceholderItem(activityViewController: UIActivityViewController) -> AnyObject {
    return ""
}

@objc func activityViewController(activityViewController:  UIActivityViewController, itemForActivityType activityType: String) -> AnyObject? {
    if activityType == UIActivityTypePostToTwitter {
        return NSURL(string:"https://twitter.com/")
    } else if activityType == UIActivityTypePostToFacebook {
        return NSURL(string:"https://www.facebook.com/")
    }
    return nil
 }
}

现在只需将上述课程添加为activityItems的{{1}}
```
UIActivityViewController
```
现在，我们可以为 twitter 和 fb

@IBAction func share(sender: AnyObject) {
   let activityVC = UIActivityViewController(activityItems: [shareDifferentUrl()] as [AnyObject], applicationActivities: nil)
   self.navigationController?.presentViewController(activityVC, animated: true, completion: nil)
}
