我在ios7中使用UIActivity.只需几行代码即可正常工作.现在我想添加Instagram分享按钮.有没有办法将自定义按钮添加到操作表？
这就是我创建UIActivityViewController的方式：
NSString *textToShare = self.navigationItem.title; NSArray *itemsToShare = @[textToShare,[imagesArray objectAtIndex:afImgViewer.currentImage]]; UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil]; activityVC.excludedActivityTypes = @[UIActivityTypePrint,UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact]; //or whichever you don't need [self presentViewController:activityVC animated:YES completion:nil];
