小编Avi*_*are的帖子

我在为内部测试选择构建时得到了这条消息.有关在info.plist中设置ITSAppUsesNonExemptEncryption的含义是什么意思？有必要吗？

我有两个文本字段的电子邮件和密码.当在常规视图上显示字段时,以下代码可以正常工作,但是当它们在弹出窗口上时,resignFirstResponder不起作用(becomeFirstResponder工作).两个字段都调用了textFieldsShouldReturn.如果我遗失了什么,不知道吗？谢谢!

  - (BOOL)textFieldShouldReturn:(UITextField *)theTextField {

     if (theTextField == email) {
         [password becomeFirstResponder];
         return NO;
     }

     [theTextField resignFirstResponder];
     return NO;
}

我已经使用以下iOS 8,9代码:

 UIMutableUserNotificationAction *action1;
    action1 = [[UIMutableUserNotificationAction alloc] init];
    [action1 setActivationMode:UIUserNotificationActivationModeBackground];
    [action1 setTitle:@"REJECT"];
    [action1 setIdentifier:NotificationActionOneIdent];
    [action1 setDestructive:NO];
    [action1 setAuthenticationRequired:NO];

    UIMutableUserNotificationAction *action2;
    action2 = [[UIMutableUserNotificationAction alloc] init];
    [action2 setActivationMode:UIUserNotificationActivationModeBackground];////UIUserNotificationActivationModeBackground
    [action2 setTitle:@"ACCEPT"];
    [action2 setIdentifier:NotificationActionTwoIdent];
    [action2 setDestructive:NO];
    [action2 setAuthenticationRequired:NO];

    UIMutableUserNotificationCategory *actionCategory;
    actionCategory = [[UIMutableUserNotificationCategory alloc] init];
    [actionCategory setIdentifier:NotificationCategoryIdent];
    [actionCategory setActions:@[action1, action2]
                    forContext:UIUserNotificationActionContextDefault];

    NSSet *categories = [NSSet setWithObject:actionCategory];

    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:
                                        UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:categories];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

委托方法处理:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
//Handle according to app state …

我们正在使用JavaScript代码滚动到具有给定ID的div。我尝试使用

jQuery.animate({scrollTop: number})

window.scrollTo(0, number) 

setTimeout(function() {window.scrollTo(0, number);}, 1000)

我还尝试添加#element_id到url中以滚动到element_id。

这些选项均无效。有什么办法可以使其正常工作吗？

iOS：9.2.1

铬：48.0.2564.87

我的ContentView中有太多子视图，现在我想要UIScrollview中的contentView，但是如果这样做，我将失去所有子视图的约束。在UIScrollview中的Editor-> Embed无法正常工作。

有什么方法可以将ContentView嵌入UIScrollView中吗？谢谢

我的应用程序还没有上线。我从App Store Connect. 我想在社交媒体应用上分享应用链接。我使用了UIActivityViewController：

let string1 = "itms-apps://itunes.apple.com/app/idXXXXXXX"
let url = NSURL(string: string1)

let shareItems = [UIApplication.sharedApplication().openURL(url!)]
    
let activityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
self.presentViewController(activityViewController, animated: true, completion: nil)

问题：它没有显示一些社交媒体应用程序，如 WhatsApp。

我需要插入和删除选项,所以......

self.navigationItem.rightBarButtonItem = self.editButtonItem;
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addItem:)];
self.navigationItem.leftBarButtonItem = addButton;

到目前为止,这一切都很好.我完成了"删除"编程,但是"插入"有问题

   - (void)addItem:sender {
}

我在addItem中添加什么来启动"编辑模式"并将我的EditingStyle更改为UITableViewCellEditingStyleInsert？在Apple库中看到的iteminputcontroller到底是什么？对此没有任何解释,帮助是模糊的在线:(
