我通过这样的方式，只能获得全是 0,明显不对！！！你知道原因不！

QGyroscope *gyroscope;

QGyroscopeReading *reader;

gyroscope = new QGyroscope(this);
gyroscope->start();
reader = gyroscope->reading();
qreal x = reader->x();
qreal y = reader->y();
qreal z = reader->z();



qDebug()<<"x 是：" <<x;
qDebug()<<"y 是：" <<y;
qDebug()<<"z 是：" <<z;
ui->label_y->setText(QString::number(y));
ui->label_x->setText(QString::number(x));
ui->label_z->setText(QString::number(z));
