Re: How to optimize image loading during core animation?

Hello, since no one replied so far, I’d take a try. I’m not much familiar with desktop Cocoa, but on iOS we have to be careful to keep longer actions from the main thread, since delays in the main thread block the UI. Isn’t this about the same issue? Image loading would be the first thing I wo

Actually, now that I think of it, an even simpler, more sweeping solution is to make the split view controller your own UISplitViewController subclass, and implement didReceiveMemoryWarning to return immediately: - (void) didReceiveMemoryWarning { return; } Now the detail view will never be

Graham, I thought there was a long process to make the control even visible to IB? I could create a custom view and set the class, but that wouldn't show the button would it? Thanks, Bruce On Feb 16, 2011, at 4:51 PM, Graham Cox wrote: > > On 17/02/2011, at 10:17 AM, Bruce Cresan
