I just found that SDL is crashing in the iPad simulator for iOS 3.2 but not for
iOS 4.2 or over when compiling with Xcode 4.0.2.
The Xcode debugger points to line 127 in video/uikit/SDL_uikitopenglview.m as
the line that triggers the crash.
On those lines one can find:
/* Use the main screen scale (for retina display support) */
if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
self.contentScaleFactor = [UIScreen mainScreen].scale;
I believe the problem to be that the "scale" selector is supported in iOS 3.2
in the iPad, but contentScaleFactor is not.
I'm no expert in Objective-C, but I believe the following code to be more
correct (it doesn't crash for me):
/* Use the main screen scale (for retina display support) */
if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)] &&
[self respondsToSelector:@selector(contentScaleFactor)])
self.contentScaleFactor = [UIScreen mainScreen].scale;
The same check is being performed in line 155 so I imagine it will crash there,
too.

yeah, -scale was introduced in 3.2 but made available only in 4.0, weird
anyways we just need to check against contentScaleFactor as we can be sure that
both are availble starting from 4.0
the attached patch addresses this

Simple DirectMedia Layer
(SDL)
Version 1.3
---
http://www.libsdl.org/
This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.
The current version supports Windows, Windows CE, Mac OS X, Linux, FreeBSD,
NetBSD, OpenBSD, BSD/OS, Solaris, iOS, and Android. The code contains
support for other operating systems but those are not officially supported.
SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
Go, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
Pike, Pliant, Python, Ruby, and Smalltalk.
This library is distributed under the zlib license, which can be found
in the file "COPYING".
The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "docs/index.html", and
a documentation wiki is available online at:
http://www.libsdl.org/cgi/docwiki.cgi
The test programs in the "test" subdirectory are in the public domain.
Frequently asked questions are answered online:
http://www.libsdl.org/faq.php
If you need help with the library, or just want to discuss SDL related
issues, you can join the developers mailing list:

Enjoy!
