开发遇到的错误

在开发中的打印提示中总是有这个提示
_NSZombie_NSURLRequestInternal is implemented in both ?? and ??. One of the two will be used. Which one is undefined.

我出现这个的原因是

@property (nonatomic, strong) TSMIneVCL * mineVCL;


- (TSMIneVCL *)mineVCL {
    if (!_mineVCL) {
        _mineVCL = [[TSMIneVCL alloc] init];
    }
    return _mineVCL;
}

打印结果

修改

@property (nonatomic, weak) TSMIneVCL * mineVCL;

TSMineVCM * vc = [[TSMineVCM alloc] init];
self.mineVCM = vc;
