iOS SDK5升级类库问题

问题描述：今天小新升级iOS SDK5，发现Stupid不能编译了。具体报错信息如下：

ld: library not found for -lz.1.2.3
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang failed with exit code 1

问题分析：看来是找不到类库的问题，lz.1.2.3对应的是libz.1.2.3.dylib。而/Developer/Platforms/iPhoneOS.platform/DeviceSupport/Latest/Symbols/usr/lib目录下只有libz.1.2.5.dylib。

问题解决：在project设置里重新引到新版本的类库，一切ok了。

UIButton无法改变大小尺寸

问题描述：Touch Team做Stupid。发现4.0以上按钮尺寸正常，而4.0以下按钮会大一倍。按钮点击等都很正常。

问题分析：UIButton的frame和bonus都不能改变其尺寸。尺寸一直是图片的原始大小。因为4.0以下一般都不是高清屏，所以要对原始图片缩小尺寸。

问题解决：仔细检查代码后，[UIButton setImage: forState:]改为[UIButton setBackgroundImage: forState:]，一切ok了。

[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。
