用 lipo 命令裁剪出需要的 architecture
    iOS 上的 framework 和 .a 库一般会同时支持多个 architecture, 比如 i386, armv7, armv7s 等。
    为了减小程序的尺寸，可能需要裁剪掉不需要的 architecture, 这时就需要使用 lipo 命令给程序瘦身。
     Step1: 查看目标库文件支持的 architecture, 两个选择
                1.1 lipo -info 目标库文件
                 1.2 file 目标库文件
    Step2: 生成只支持一个 architecture 的 库文件
                 lipo 目标库文件 -thin 目标architecture 目标文件名
                 eg:    lipo MVC -thin i386 MVC.i386
                 eg1:    lipo MVC -thin armv7 MVC.armv7

       最后，删掉旧的库文件，把目标库文件改成原来的名字，进行替换即可。

     YEAH！

hidesBottomBarWhenPushed处理方案

1
down vote
Not sure if a solution was found for this but I just managed to get this working.

My scenario:

I have a UITabBarController with 4 tab bar items. On one of the tab bar items it loads a UIViewController with buttons on it. The buttons calls a IBOutlet function that loads another UIViewController which contains the a tab bar at the bottom.

After many trial & error........

On the IBOutlet function, I do the following:

{
self.hidesBottomBarWhenPushed = YES;
/* Push the new controller with tab bar */
}
This was working fine with the UITabBarController's tab bar sliding to the left and my tab bar from the pushed controller sliding from the right.

Obviously from functionality perspective I need to push the initial UITabBarController's tar bar back in when "going back".

After many trial & error........

I have the method viewWillDisappear in the UIViewController that pushes the UIViewController with tab bar as:

- (void) viewWillDisappear:(BOOL)animated
{
    self.hidesBottomBarWhenPushed = NO;
}
I ran a few quick tests on this in the simulator and it seems to work fine.

Some contributors suggests that this is bad UI but I am trying this out at the moment to see how it works out.

Happy to receive (cop) any feedbacks.
