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：
