  • libc++abi.dylib: terminate_handler unexpectedly threw an exception

    在执行一个界面的时候,就是一直libc++abi.dylib: terminate_handler unexpectedly threw an exception。也没有指明是哪里错误,后来经检查发现是数组越界
    - (CellInfo_t *)getCellInfo:(NSIndexPath *)indexPath{
        NSInteger row=[self getCellInfoFromIndex:indexPath];
        return self.cellInfoArrayTwo[row];
    }
    - (NSInteger)getCellInfoFromIndex:(NSIndexPath *)indexPath{
        NSInteger section=indexPath.section;
        if (section==0) {
            return indexPath.row;
        }else if (section==1){
            return [self numberOfRowsInSection:0]+indexPath.row;
        }else{
            NSAssert(NO, @"Invalid cellInfo From Index");
        }
        return -1;
    }
    - (NSInteger)numberOfRowsInSection:(NSInteger)section{
        switch (section)
        {
            case 0:return 1;
            case 1:return 12;
            default:
                NSAssert(NO, @"Invalid section index");
                break;
        }
        return -1;
    }
    后经检查发现,我把
    [self numberOfRowsInSection:0]的0写成1了,导致数组一直越界。程序crash
