Just for reference's sake:
@interface NSObject (BlockOnMainThread)
- (void)performBlockOnMainThread:(void(^block)());
@end
@interface NSObject (BlockOnMainThreadPrivate)
- (void)performBlock:(void(^block)());
@end
@implementation NSObject (BlockOnMainThread)
- (void)performBlockOnMainThread:(void(^block)())
{
[self performSelector:(performBlock:) withObject:[block copy]
waitUntilDone:YES];
}
- (void)performBlock:(void(^block)())
{
block();
[block release];
}
@end
Note though, this was typed entirely into my email client, so YMMV.
