The split view controller has a two column layout the master column on the left and the detail on the right. I want to be able to set the width of the columns. I came across this solution in stack overflow. It works but does not respond to numbers over 410 which means I can't make the split 50/50. Any ideas why it is limiting me and how I get around it? Thanks edit: This is an iPad only project not iPhone From stack overflow Code: In IOS 8.0 you can easily do this by doing the following: In your MasterSplitViewController.h add @property(nonatomic, assign) CGFloat maximumPrimaryColumnWidth NS_AVAILABLE_IOS(8_0); In your MasterSplitViewController.m viewDidLoad method add self.maximumPrimaryColumnWidth = 100; self.splitViewController.maximumPrimaryColumnWidth = self.maximumPrimaryColumnWidth; This is a really good, simple and easy feature of IOS 8.
