Xcode7 创建framework

第一步:制作framework


2)创建我们将要封装的类,eg:创建一个MyObject类,代码如下:


@interface MyObject : NSObject
-(void)myLog;
@end
 
@implementation MyObject
-(void)myLog{
    NSLog(@"framework");
}
@end

3)新建Target


然后选择Aggregate


之后我们在target的Build Phases中点击加号:


增加一个Run Script:


改变运行的Target ,填写下边的shell脚本

 在里面添加如下的脚本:

<code class="bash" style="padding:0px; font-family:Menlo,Monaco,Consolas,'Courier New',monospace; font-size:12px; border:none; background-color:transparent"><span class="hljs-comment" style="color:#93a1a1;"># Sets the target folders and the final framework product.</span>
<span style="color:#93a1a1;"></span><span class="hljs-comment" style="color:#93a1a1;"># 如果工程名称和Framework的Target名称不一样的话,要自定义FMKNAME</span>
<span class="hljs-comment" style="color:#93a1a1;"># 例如: FMK_NAME = "MyFramework"</span>

之后我们运行程序,需要注意的一点事,如果要支持64位,需要在编译选项中设置,如下:


到此时,我们的framework库文件就制作完成,在xcode的window->projects中选中我们的这个项目,点击进入文件夹的小箭头:

product中便可以找到我们的framework文件,我们将其赋值出来即可以使用。到此我们的framework就制作完成了


我们测试一下,新建一个工程,将刚才制作的静态库导入,如下加入头文件,调用方法,可以使用


#import <MyFramework/MyObject.h>
  MyObject * obj = [[MyObject alloc]init];
     [obj myLog];


第二步:解决会遇到的问题:

原文链接:XCode6添加自定义framework运行真机出现dyld: Library not loaded的解决方法


1、直接添加上面制作好的framework,会发报如下错误:

dyld: Library not loaded: @rpath/RLLibrary.framework/RLLibrary
  Referenced from: /var/mobile/Applications/AE92B234-A818-445E-9D69-96E232BD50EB/RLProjectDemo.app/RLProjectDemo
  Reason: image not found
(lldb) 

讨论:看网上不少人说是将上图Link Binary With Libraries中的Required改为Optional就没事了,实际真机运行发现不是回事,即使不报错了,但是也是无法运行程序。

解决方法:仔细看错误原因,应该是没有找到framework文件包,So,怎么编译时打包进去呢?如下图,点击那个+号:

添加Copy Files节点,在Destination中选Frameworks,再点击下面+号,选择自定义的framework,ok,真机 Build,Run,这个世界美好了。

2、即使上面都已经配置好了,程序运行ok,但是当引用库中.h文件时,会警告“missing submodule 'XXXframework'”

解决方法:创建库文件时,只要在库文件中与库同名.h文件中添加要暴露的.h文件,有点绕,可以看下图:
