CustomSegmentedControls crashes in iOS3.x

[orff]

the call to UIGraphicsBeginImageContextWithOptions

in CustomSegmentedControlsViewController is not OS3.x friendly. It will crash because the call is a C call and not Obj C.

Here is a fix ( May not work well with non opaque images, but stops the crashing):

    CGSize size = CGSizeMake(buttonWidth, image.size.height);
if (UIGraphicsBeginImageContextWithOptions!=NULL) {
    UIGraphicsBeginImageContextWithOptions(size, NO, 0.0);
} else {
    UIGraphicsBeginImageContext(size);  
}
