问题 I've got a basic storyboard setup that segue transitions through some view controllers by clicking a button. I've also got a Navigation controller at the root of the storyboard, hoping this segue chain performs similarly to how a series of Pushes used to work. The functionality is all there, as is the navigation bar controlling, however the transitions all have the new views coming in from the bottom and sliding up, Cover Vertical. How do I configure this to slide in from the right side like

In this example, I placed a label, pinned it's leading and top space, then moved the label.

问题 I want my application to animate an ellipse to a new position everytime a certain event happens. For testing purposes I made a button that changes a viewmodel property and this property is bound to a datatrigger that fires the animation, but later on I want the viewmodel to trigger it based on other events I haven't implemented yet - that's why I can't use the eventtrigger being bound to that button directly in the view, I need the viewmodel.

问题 In the WWDC video "Session 309 - Introducing Interface Builder Storyboarding" the speaker adds a table view controller and creates a cell in IB that can be directly linked to outlets in the app (at about 13:30 in the video). Can this be done without story boards and if so, how to do it? 回答1: You can create a nib file with just a table cell in it, set the class to a custom UITableViewCell subclass, and link any cell subviews to outlets in the class. 来源： https://stackoverflow.com/questions
