我希望在用户分享到
时执行某些操作- (void)sharingService:(NSSharingService *)sharingService didShareItems:(NSArray *)items
{
BOOL isSafariReadingList = [sharingService.description rangeOfString:NSSharingServiceNameAddToSafariReadingList].location != NSNotFound;
}
我在NSSharingService
找不到任何可以与常数比较的属性。我错过了什么吗?!

由于似乎没有答案(提交http://openradar.appspot.com/16114564),我创建了一个类别
@implementation NSSharingService (ActivityType)
- (NSString*)activityType {
NSRange range = [self.description rangeOfString:@"\\[com.apple.share.*\\]" options:NSRegularExpressionSearch];
range.location++; // Start after [
range.length -= 2; // Remove both [ and ]
return [self.description substringWithRange:range];
}
@end
然后您可以通过以下方式使用它:
[[sharingService activityType] isEqualToString:NSSharingServiceNameAddToSafariReadingList];
[@[NSSharingServiceNameAddToSafariReadingList, NSSharingServiceNameAddToIPhoto]
containsObject:[sharingService activityType]];
我想Apple认为我们不想知道人们从Picker中挑选了哪些服务。
解析“com.apple.share.System”显然很危险,但这是我看到避免一组rangeOfString || rangeOfString || rangeOfString….
的唯一方法。

此外,作为参考,以下是NSSharingServiceName*
常量的一些值,所有值均以com.apple.share.

此检查的等价物适用于我的Swift代码:
sharingService == NSSharingService(named: NSSharingServiceNameAddToSafariReadingList)
