读注册表void Widget::on_pushButton_read_clicked()

    QString  plistPath = QDir::homePath() + "/Library/Preferences/com.xx.plist";

    QSettings readReg(plistPath, QSettings::NativeFormat);

    QString email = readReg.value("email", QVariant()).toString();

    qDebug() << "email=========" << email;

}写注册表：

void Widget::on_pushButton_write_clicked()

    QString  plistPath = QDir::homePath() + "/Library/Preferences/com.xx.plist";

    QSettings writeReg(plistPath, QSettings::NativeFormat);

    writeReg.setValue("Mac", "10.10.4");

}com.xx.plist文件内容：<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict>        <key>Mac</key>        <string>10.10.4</string>        <key>email</key>        <string>ghdfgdf</string></dict></plist>
