Apple Mach-O链接器(Id)错误

Question

第一次遇到这个错误,我环顾四周,无法找到帮助我的解决方案,我已经清理了我的构建并检查以确保我正在编译最新的固件.

这发生在我累了实现我在这里找到的可达性解决方案后, 我导入了两个可达性文件(.m/.h),然后将此代码添加到.m文件中,并在该文件中延迟了.h可达性文件

-(BOOL)reachable {
    Reachability*r =[Reachability reachabilityWithHostName:@"enbr.co.cc"];
    NetworkStatus internetStatus =[r currentReachabilityStatus];
    if(internetStatus ==NotReachable){
        return NO;
    }
    return YES;}

之后我从我的两个viwcontrollers viewwillappear方法中调用了这个函数,就像这样.

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];


    //-- Check Reachability START ---->
    Reachability *reach = [[Reachability alloc] init];

    if ([reach reachable]) {
            NSLog(@"Reachable");
    }
    else {
        NSLog(@"Not Reachable");
    }
     //-- Check Reachability END ---->
}

没有错误产生,直到我试图在模拟器中构建和运行.这是我收到的错误:(

所以,问题已经解决了.

发生了什么事情,当我将可访问性文件导入到我的构建中时发生了一些有趣的事情,并且我以某种方式删除了我的构建中已经使用的可访问性文件,这些文件被我用于传输数据的"所有看到的"ASIHTTPRequest方法使用.这搞砸了一切.

长话短说,我更换了文件,一切正常,我也发现ASIHTTPTequest正在为我提供可达性:)这有多酷.
