在我的UIActivityViewController中,我使用完成处理程序来执行“成功共享”通知.它的工作原理但我唯一的问题是,如果用户按下取消,它仍会显示通知.
这是我的完成处理程序代码,
[controller setCompletionHandler:^(NSString *activityType,BOOL completed) {
CWStatusBarNotification *notification = [CWStatusBarNotification new];
[notification displayNotificationWithMessage:@"✓ Successfully Shared Centre!"
forDuration:3.0f];
notification.notificationLabelBackgroundColor = [UIColor colorWithRed:38.0f/255.0f green:81.0f/255.0f blue:123.0f/255.0f alpha:1.0f];
notification.notificationLabelTextColor = [UIColor whiteColor];
}];
谢谢您的帮助！
解决方法
这就是完成的论证：
[controller setCompletionHandler:^(NSString *activityType,BOOL completed) {
if (!completed) return;
CWStatusBarNotification *notification = [CWStatusBarNotification new];
[notification displayNotificationWithMessage:@"✓ Successfully Shared Centre!"
forDuration:3.0f];
notification.notificationLabelBackgroundColor = [UIColor colorWithRed:38.0f/255.0f green:81.0f/255.0f blue:123.0f/255.0f alpha:1.0f];
notification.notificationLabelTextColor = [UIColor whiteColor];
}];
