[UIWindow setRootViewController:]需要4.0以上支持

问题描述：今天Touch Team出Stupid测试版，安装20多台iPhone、iTouch、iPad，都可以安装。但是有一台iPhone（3.1.2）报错，不能安装。注：其他设备基本都在4.0以上。

问题分析：因为是调试安装，所以能看到报错信息，如下：

报错的语句是：

self.window.rootViewController = startViewController;

仔细查看报错信息，发现这句报错：-[UIWindow setRootViewController:]: unrecognized selector sent to instance。查看setRootViewController方法，发现需要4.0以上支持。

解决方案：把出错代码：

self.window.rootViewController = startViewController;

替换为：

if( [[[UIDevice currentDevice] systemVersion] compare:@"4.0" options:NSNumericSearch] == NSOrderedAscending )
[self.window addSubview:self.mainViewController.view];
else self.window.rootViewController = self.mainViewController;

一切ok了。

后台运行App导致无法调试

问题描述：Touch Team做Stupid，调试的时候console报以下问题：
warning: Unable to read symbols for /Library/MobileSubstrate/MobileSubstrate.dylib (file not found). warning: Unable to read symbols for /Library/Frameworks/CydiaSubstrate.framework/Libraries/SubstrateLoader.dylib (file not found). 2011-09-21 12:46:54.465 FSStupid[18953:607] MS:Notice: Installing: com.flipscript.stupid [FSStupid] (550.58) 2011-09-21 12:46:54.489 FSStupid[18953:607] MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/Activator.dylib warning: Unable to read symbols for /Library/MobileSubstrate/DynamicLibraries/Activator.dylib (file not found). 2011-09-21 12:46:54.752 FSStupid[18953:607] MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/QQInput.dylib warning: Unable to read symbols for /Library/MobileSubstrate/DynamicLibraries/QQInput.dylib (file not found). warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J3)/Symbols/usr/lib/libsubstrate.dylib (file not found). 2011-09-21 12:46:54.889 FSStupid[18953:607] MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/libstatusbar.dylib warning: Unable to read symbols for /Library/MobileSubstrate/DynamicLibraries/libstatusbar.dylib (file not found).

问题分析：用其他的几台设备测试，一切正常。用有问题的那台机器，然后直接运行，也一切正常。网上查了下，是一些后台运行的程序可能搞鬼（如报错信息中的：QQInput.dylib、libstatusbar.dylib等）

问题解决：用Cydia删除一些dylib，就没有问题了。

《部落：一呼百应的力量》

部落指的是任何一群人，规模可大可小，他们因追随领导、志同道合而相互联系在一起。人类其实数百万年前就有部落的出现，随之还形成了宗教、种族、政治或甚至音乐。

“没有领导不成部落---没有部落也就无所谓领导。”

“领导者有追随者，而管理者只有员工。管理者制造产品，而领导者实现变革。”

“多数组织将时间花在针对所谓目标人群的营销上，聪明的组织创建部落。”

　　刘青云：搞了兄弟的老婆，一面忍着女人和兄弟纠缠不清（何其屈辱！），一面瞒着兄弟不敢见光（何其内疚！）。这件事的关键在于，是那对原配夫妻感情破裂在先，所以刘青云的介入其实并无太多道德错误。由此我们也看出了刘青云的性格：受绑于人情，优柔寡断近乎妇人之仁。毫无侵略性，不能伤害任何人。
　　
　　古天乐：被家庭负担逼到焦头烂额。工作上，级别低却资历老，一幅屌样儿，毫无前途。中年潦倒最是水深火热，所以他对金钱的态度最分裂。红着眼睛仇富的是他：“他们随便一赚一千万，我们辛辛苦苦一个月赚两万，不把他们送进监狱我不是人！”而当机会出现时最早暴露贪念，行为越轨的也是他：我儿子治病要一大笔钱！
　　
　　吴彦祖：青年才俊，却被准岳父指为入错行：做警察做到顶，薪水还不如在岳父的财团里做个低级员工。各位，这样的质疑，绝非只是经济能力的上的质疑，乃至是对一个人存在价值的质疑：你以为是事业和理想的那样东西，被人条理分明有理有据的贬做一文不值。这对任何男人来说都是奇耻大辱，如不能予以反击，只怕自尊自信都会被彻底摧毁。所以比起古天乐的现实需要，吴彦祖对金钱的渴望更近乎形而上：他需要用钱来解决自己的价值危机，用钱在准岳父面前证明自己一点什么。这也就是为什么吴彦祖貌似低调内敛，一出手却比古天乐还疯狂得多。

最后三个一瞬间都堕落了，而活着的只有刘青云。
