IOS FAQ (What ghost series)--problems that cannot be modified from the code after adding Size Class mizmization in Storyboard, storyboardsizeclass

 

 

Preface

The company's products are compatible with the iPhone and iPad at the same time, and insist on using Storyboard for adaptation. Today, another pitfall (previously encountered) thinks it is a ghost problem of XCode.

Body

I. Purpose/Requirement

The text on iPhone 4, iPhone 6, and iPad must have different font sizes and image widths.

 

Ii. Problems

As shown in: On the Storyboard, set the "18" character on the iPad for UILabel. The image uses 160 on the iPad. Then, drag the constraint into the ViewController and determine that it is the value of iPhone 4 to fix the constraint.

However, you find that no matter how you change the code, it does not work !! Clean almost gave up countless times !! I thought it would be the impact of Add Size Class mizmization. It would be nice to delete it!

 

Iii. Solution

What else can be done? Only Add Size Class Customization can be removed. In addition, you can use NSLayoutConstraint for [iOS] screen adaptation.
