uitabbarcontroller

问题 How does one hide the UITabBar programmatically?

Typical answer here. 2) Walk through the tabbar controller's view hierarchy and modify the tab bar's frame and/or visibility. Typical answer here. But both sorts of answers fall short, imo. 1) What if we need to hide

问题 I am fairly new to swift and am trying to create a movie database application using TMDB from Apiary. I have created the layout of the view controllers for one category. However, I am planning to have multiple categories, the but only difference between them is the data I retrieve from the API. For example "now_playing" key gets the now playing list and the "top_rated" key gets the top rated list of movies. When I was initially doing this I created the tab bar controller in AppDelegate.swift

问题 I have a tab bar controller-based application and I am using IQKeyboardManager to handle form-like stuff. Step 1: Tab bar controller with bottom a UITextView inside a UIView . Check Image 1. Step2: When I click on UITextView , the keyboard appears but a blank space is appearing due to the tab bar.
