据我了解，如果此滑动在圆圈之外，您不希望选择器对滑动手势做出反应。在这种情况下，在滑动选择器的开头，您应该检查滑动是否在圆圈上方，如下所示：

CGPoint lClick = [recognizer locationOfTouch:0 inView:self.view];

    //Distance from the center of the circle to the taped point
    int lDistance = sqrt(pow(lClick.x - lCircleCenter.x, 2) + pow(lClick.y - lCircleCenter.y, 2));

    if ((int)lDistance > (int)lCircleRadius) {
        return;
    }

希望对你有帮助
