在Xcode IDE中用C ++初始化我自己的類的向量

Question

我當前遇到的問題如下：

我試圖在僅包含SingleBox對象的main.cpp文件中構造一個向量（SingleBox是我定義的類），但是，當我嘗試填充該向量或調整其大小時，該向量從不包含任何SingleBox對象，並且嘗試填充或調整矢量大小的下面的代碼從未在main.cpp文件中執行。

在此先感謝您提供協助解決此問題的任何人。

文件main.cpp

#include <iostream>
#include "SingleBox.h"
#include "NineBox.h"

int main( int argc, const char * argv[] )
{
    std::vector< SingleBox > vec;
    std::cout << "Below is the attempt to populate: \n";
    vec.push_back( SingleBox( 0, 0 ) );
    std::cout << "Nothing from this point onward executes...\n";
    std::cout << "The size: " << vec.size() << std::endl;

    return 0;
}

文件SingleBox.h

Xcode IDE沒有運行我的代碼的一部分，因為已經設置了斷點。 通過g ++編譯器運行代碼可驗證我的代碼是否可運行，並且從Xcode刪除斷點可讓我的代碼在IDE中運行。
