最q在做Apple的IOS开发，有开发静态库的需求，本nIOS的开发，只允讔R态库或者Framework。在Xcode上没有找到允许编译，如同Android上的*.so和Win32上的dllq样的说法。不qFrameworkq样的框Ӟ估计也是cM动态库的实玎ͼ不过没有具体研究q，后箋l箋深入研究?/p>
我这个文的静态库的开发是ZXcode4.2和iOS SDK5.0~写的。Xcode4跟之前的Xcode3q是有不的差别的?br style="line-height: normal; " />
下面q单写一个静态库和一个调用静态库的例子?br style="line-height: normal; " />
静态库的编写：
1.静态库工程的徏立：
Xcode New一个新的projectQ选择IOS下面的Framework&LibraryQ下面有一个Cocoa Touch Static Library。直接nextd立一?span style="font-family: Menlo; color: #ff3f47; ">Printq样的工E?/p>
2.工程建立
我们d很简单的"- (void)printA;"?+ (void)printB;"的方法，q个Ҏ的实C是很单的Q在*.m文g中的实现是一?NSLogQ@“”);"q样我们~译出来的libstaticlib可以被其他的IOS工程q行调用了。这块注意一下，目前我们?span style="color: #ff6666; ">Print->iOS Device
3.~译前准?/span>
q里分release与debug版本Q需要设|一?/p>
4.OKQ编?/span>
我们可以在Products下面扑ֈ我们~译生成的libstaticlib.aq个文g?br />
注意未编译前为红Ԍ? ~译后ؓ黑色Q?nbsp;?br />
5.ok
在右?nbsp;q个文g上右键Open In Finder。这时候我们打开了一个文件夹Q里面有一?span style="color: #6652cc; ">libPrint.a。后面我们l编写一个调用这?span style="color: #6652cc; ">libPrint.a的App。但是这个App在编译时候会出错Q通过q个错误的解冻I说明Xcode的一些编译相关的东西。这里，我们在command下面Ҏ路径扑ֈq个文gQ用q个非常重要的命令查看一下这个lib的信息！
打开l端写入如下命oQ?span style="color: #ff0000; ">q是什么？q就是所在的路径
以下均是在自qmac上的路径。你需要将/Users/pjk1129/Library/Developer/Xcode/DerivedData/Print-dgfkluumuexoxhcapzidtsmdgqcj/Build/Products/ 替换成你的\径?/span>
cd /Users/pjk1129/Library/Developer/Xcode/DerivedData/Print-dgfkluumuexoxhcapzidtsmdgqcj/Build/Products/
我们手动打开q个路径Q可以看到如下信息：Release-iphoneos
q个是给真机用的Q那我们要给模拟器和真机装的静态库应该都能用才好。这个下面介l！Q！Q！
然后再在l端 打开q个文gQ?span style="color: #ff0000; ">cd /Users/user/Library/Developer/Xcode/DerivedData/UItab-dbvoszbzpavyglaboxgflvrnzfce/Build/Products/Debug-iphoneos
命o是：lipo -info libPrint.aQ可以看到显C的l果是：Arch?nbsp; Arm7。下面我会具体介l一下?/p>
6.建立一个调用这个libPrint.a的应?/span>
应用很单了Q我们添加刚才libPrint.a?.h文g?nbsp;然后在这个工E的Build Phases的Link Binary With Library里面d我们刚才拯出来的那个libPrint.a?br />
7.插入了h和a文g?/span>
我们可以在control里面调用q个libPrint.a 函数了?br />
#import "AstroDiskAppDelegate.h"
#import "Print.h"@implementation AstroDiskAppDelegate
@synthesize window = _window;
- (void)dealloc
{
[_window release];
[_viewController release];
[super dealloc];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//调用libPrint.a
[Print printB];
Print *print = [[[Print alloc] init] autorelease];
[print printA];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
[self.window makeKeyAndVisible];
return YES;
}
8.OKQ编译运行这个应用程序?/span>
~译出现错误了。这个就是这文档的关键了。主要就是ؓ了介l编译静态库相关的东ѝ?br />
9.可以看到undefine symbols for architecture i386q样的错误?/span>
其实q个错误原因很简单，是因ؓQ我们用错了~译出来的libUITab.a libQ在模拟器里面，我们需要的是基于i386构架~译的static libQ但是这个a文gQ大家还记得前面说的arm6 arm7构架的么。这个a其实是在iphoneq个arm构架上运行的代码。其实show in finder指向的是一个ios device的库Qƈ不是i386模拟器下的库。那如何~译i386的库呢？看见W二张图片的Print>IOS Device了么Q我们将q个iOS Device修改成iPhone5.0 Simulator。在q行~译Q这样就可以~译出i386下面的库。这个时候我们show in finder打开的文件夹q是ios device下的库。我们最好自己去那个目录下看一下。这里我们用commandL看了一下目录情况，如下Q可以看C个iphoneos的目录和一个simulator的目录?br />
然后我们再看看这个目录与W?条所C的目录有什么不同！ 同样也有一个libPrint.a文g?br />
10.错误原因分析
Release-iphoneos里面的是Zarm6 arm7~译出来的库文g。Release-iphonesimulator文g夹下面的是基于i386~译出来的文件?/span>
11.合ƈ.a文gQ制作通用静态库
q二个库一个是用于真机q行的一个是用于模拟器运行的.其实我们可以利用lipo这二个文g打包成一个通用的a文g。命令如下：
?span style="color: #ff0000; ">/Users/user/Library/Developer/Xcode/DerivedData/UITab-dgfkluumuexoxhcapzidtsmdgqcj/Build/Products替换成你的\径?nbsp;
?span style="color: #0055ff; ">/Users/user/Desktop/libPrint.a替换成合q后的\径?nbsp;
lipo -create /Users/pjk1129/Library/Developer/Xcode/DerivedData/Print-dgfkluumuexoxhcapzidtsmdgqcj/Build/Products/Release-iphonesimulator/libPrint.a /Users/pjk1129/Library/Developer/Xcode/DerivedData/Print-dgfkluumuexoxhcapzidtsmdgqcj/Build/Products/Release-iphoneos/libPrint.a -output /Users/pjk1129/Desktop/libPrint.a
12.打包以后的库文gQ我们查看信?/span>
然后打入如下命oQlipo -info /Users/pjk1129/Desktop/libPrint.a
可以看到如下信息Q?br />
如上Q你已经看到了，它具备了i386和arm7的条件?nbsp;现在我们q个静态库Q支持的构架已经是armv7 i386了?br />
q个通用库生成后Q我们将原来Q调用这个库q行替换一下，在进行编译，成功~译Q运行结果如下所C：

Debugging
You can use Three20's debugging facilities instead of NSLog() / assert(). This would give you an ability to turn off debugging messages without commenting out all NSLog's, sort log messages by importance (error, warning, info).
Turn on debuggingQ打开调试Q?/h1>
These instructions are for Xcode 3:
- Right-click on project, choose "Get Info".
- In the "Build" tab, choose "Configuration => Debug" (you probably want to enable this only for debug builds)
- While in the "Build" tab, search for "Preprocessor Macros" under the "GCC 4.2 - Preprocessing" section.
- Add a declaration that reads
DEBUG. That way you enable debugging in general. - Add a declaration that reads
TTMAXLOGLEVEL=TTLOGLEVEL_INFO. By doing this, you set the default debugging output to beTTLOGLEVEL_INFO, the most descriptive one.
- Add a declaration that reads
Use debugging
Logging
Use these instead of NSLog(). Which level gets printed to the console and which doesn't depends on what's set in preprocessor macros asTTMAXLOGLEVEL (see above).
TTDERROR(text, ...) // Log level 1 TTDWARNING(text, ...) // Log level 3 TTDINFO(text, ...) // Log level 5 TTDPRINT(text, ...)
Example
If I got this in AppDelegate.m of my project HelloWorld:
- (void)applicationDidFinishLaunching:(UIApplication *)application { TTDINFO(@"Hello!"); }
...the console output would look like this:
2010-05-15 01:04:20.107 HelloWorld[65222:207] -[AppDelegate applicationDidFinishLaunching:](22): Hello! Conditional logging
This is a type of logging facility which only outputs something if a particular condition is met:
TTDCONDITIONLOG(condition, text, ...);
Example
TTDCONDITIONLOG(TTDFLAG_URLREQUEST, @"Request parameters: %@", request.parameters);
Debug-only assertions
Three20 also provides support for assertions which only work in the debug build.
TTDASSERT(condition_which_would_lead_to_application_termination_when_true);
Example
// Not that implementing safeAddSubview: is a good idea - (void)safeAddSubview:(UIView*)view { TTDASSERT(nil != view); if (nil == view) { return; } [self addSubview:view]; }
