假设有一个ini文件的内容如下:

[test]
test11=666
test22=a

[ceshi]
aaa=11
bbb=32
ccc=0

执行如下代码,遍历ini文件

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QSettings set("./test.ini",QSettings::IniFormat);
    QStringList groupList = set.childGroups();
    foreach (QString group, groupList) {
        qDebug()<<group;
        set.beginGroup(group);
        QStringList keyList = set.allKeys();
        foreach (QString key, keyList) {
            qDebug()<<key<<"      "<<set.value(key);
        }
        set.endGroup();
    }

    return a.exec();
}

打印结果如下:

还有一种更简单粗暴的遍历方法:

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QSettings set("./test.ini",QSettings::IniFormat);
    QStringList keyList = set.allKeys();
    foreach (QString key, keyList) {
        qDebug()<<key<<"      "<<set.value(key);
    }

    return a.exec();
}

打印结果如下:
