我正在尝试编辑系列//This is an example for if you want to have different data sent based on which app they choose.
//I have an NSURL pointing to a local video in "videoUrl"
//And I have NSData of a GIF in "gifData"
- (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType {
id item;
//If it's Facebook, send a video
if ([activityType isEqualToString:UIActivityTypePostToFacebook])
item = self.videoUrl;
//if its Twitter, send a GIF
else if ([activityType isEqualToString:UIActivityTypePostToTwitter])
item = self.gifData;
//if its mail, send a GIF
else if ([activityType isEqualToString:UIActivityTypeMail])
item = self.gifData;
//If it's text, send a GIF
else if ([activityType isEqualToString:UIActivityTypeMessage])
item = self.gifData;
//If it's Facebook Messenger, send a video
else if ([activityType isEqualToString:@"com.facebook.Messenger.ShareExtension"])
item = self.videoUrl;
//Just default to a video
else
item = self.videoUrl;
return item;
}
的索引。我之前实际上问了一个类似的问题，并且能够使用答案。但是，使用answer to the question I asked略有不同的目的并不能给我正确的结果，因为此代码中的最后一个print语句显示bond.to_cash_flows().amounts与以前相同。我不知道如何尝试更改系列的指数。
bond.to_cash_flows().amounts.index谢谢
