ios9 加载动态库

问题描述：
ios9 在运行时通过dlopen()方法加载动态库文件（framework），加载失败，在ios8一下版本程序运行正常。
代码如下：

// 加载应用
NSBundle *appBundle = [NSBundle bundleWithPath:appPath];
NSError *error = nil;
            
if ([appBundle loadAndReturnError:&error])
{
    NSLog(@"bundle load framework success.");
}
else
{
    NSLog(@"bundle load framework err:%@",error);
}

失败log：

bundle load framework err:Error Domain=NSCocoaErrorDomain Code=3587 "dlopen_preflight(/var/mobile/Containers/Data/Application/F34F9E7A-C129-46F5-A5C6-C82E843F764C/Documents/xxxx.framework/xxxx): no suitable image found.  Did find:
