With the release of iOS8 I have designed my table view with cells taking advantage of self sizing cells. But I need my tables to work in iOS7 as well. How do I do that? Is there a way to check whether self sizing cells is supported or not in runtime, or can I implement some table delegate methods in my controller which will not be called in iOS7?
If I try my table with self sizing cells in iOS7 I get errors on the console like this:
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
