现在,swift是开发iOS应用程序的新语言.

我们如何与AFNetworking集成或使用NSURLSession将是一个更好的选择???

请帮帮我..

我目前有一个用于聊天的应用程序.我使用UItextField作为输入框和气泡来显示消息,有些东西就像系统短信.我想在消息气泡(标签)上启用复制粘贴.问题是,当我想显示UIMenuController时,我需要复制的标签需要成为第一响应者.如果当前显示键盘,当标签成为第一响应者时,文本字段将失去焦点,因此键盘将自动隐藏.这导致UI滚动并感觉不好.无论如何,即使我需要显示菜单,我仍然可以保持键盘显示？

我添加了代码来制作带有导航功能的tabbar应用程序.

        self.objNavConCards = [[UINavigationController alloc]initWithRootViewController:objCardsVC];
        self.objNavConNotification = [[UINavigationController alloc]initWithRootViewController:objNotificationVC];
        self.objNavConSetting = [[UINavigationController alloc]initWithRootViewController:objSettingVC];
        self.objTabBarController = [[UITabBarController alloc]init];
