1.准备工作：先自己封装一个framework：http://www.cnblogs.com/sunjianfei/p/5781863.html

2.把封装好的framework压缩成zip，放到本地服务器端

3.下载压缩包，并且解压，参照：http://www.cnblogs.com/sunjianfei/p/5781799.html

4.添加并设置Application requires iPhone env。。。。。为yes

5.动态加载下载下来的framework库文件：

  NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
        NSString *bundlePath = [NSString stringWithFormat:@"%@/%@",documentDirectory,@"JFTestFramework.framework"];
        NSLog(@"2-------%@",bundlePath);
        if (![[NSFileManager defaultManager] fileExistsAtPath:bundlePath]) {
            NSLog(@"file not exist");
            return;
        }
        NSBundle *bundle = [NSBundle bundleWithPath:bundlePath];        if (!bundle || ![bundle load]) {
            NSLog(@"bundle load error");
        }
        Class loadClass= [bundle classNamed:@"JFDylib"];        if (!loadClass) {
            NSLog(@"get bundle class fail");
            return;
        }        NSObject *bundleObj = [loadClass new];        [bundleObj performSelector:@selector(showViewAfterVC: inBundle:) withObject:self withObject:bundle];
