I found an issue with this code and iOS 7.x

When a table with this custom class is inside a VC that is part of a TabBar VC, the class will seemingly get called recursively (primarily the function 'intrinsicContentSize') until an EXC_BAD_ACCESS 2 error is thrown.

I tested this with multiple VC's that already contained tables with this custom class. They work great when on their own, but as soon they are embedded into a TabBarVC, the error occurs.

This does not happen in iOS 6.x, however.

Sounds interesting, but there is an easier way to do it, which supports iOS 7 too

Just override -setContentSize method:

• (void)setContentSize:(CGSize)contentSize {
  [super setContentSize:contentSize];
  [self invalidateIntrinsicContentSize];
  }

About this problem,may i have demo with storyboard please ?

Hi patric.schenke, Do you have any Sample Project this función?

Thanks for this! Here is a Swift version that I am using https://gist.github.com/johneris/2263781090f271a7a647

About this problem,may i have demo with storyboard please ? it will be great to support swift also

Thanks, this is Swift 5 version https://gist.github.com/sseno/d0a462c600259272fa6bb96c2a76e619
