iOS Objective-C performSelector static method

It's tested OK to use the following static method calls.

Tested on Xcode Version 4.4.1 (4F1003), Apple LLVM Compiler 4.0

    [[StaticMethodClass class] performSelectorInBackground:@selector(runInThreadMethod)withObject:nil];

    [StaticMethodClass performSelectorInBackground:@selector(runInThreadMethod)withObject:nil];

    [StaticMethodClass performSelectorOnMainThread:@selector(runInThreadMethod)withObject:nil waitUntilDone:NO];

    [StaticMethodClass performSelector:@selector(runInThreadMethod) withObject:nil];

Although, there is no auto-code-completion, but it runs fine.

But when use "target", it's NOT ok to use the Class itself, should use "[StaticMethodClass class]" as the target. like.

 [NSTimer scheduledTimerWithTimeInterval:1.0 target:[StaticMethodClass class] selector:@selector(runInThreadMethod) userInfo:nil repeats:NO];
