用法
//后台线程
GCD.dispatch_async("back", new Block()
{
@Override
public void IBuild()
{
println(Thread.currentThread().getName());
GCD.dispatch_async("main", new Block()
{
@Override
public void IBuild()
{
println(Thread.currentThread().getName());
}
});
}
});
//UI线程
GCD.dispatch_async("main", new Block()
{
@Override
public void IBuild()
{
println(Thread.currentThread().getName());
}
});
public static void println(String s){
Log.i("GCDTester", s);
}
无聊写个android的GCDのdispatch_async
