emitterCells:CAEmitterCell对象的数组,被用于把粒子投放到layer上 birthRate:可以通俗的理解为发射源的个数,默认1.0.当前每秒产生的真实粒子数为=CAEmitterLayer的birthRate*子粒子的birthRate: lifetime:The cell lifetime range is multiplied by this value when particles are created. Defaults to one. emitterPosi
最近在做一个项目,需要用树莓派作为AP发射wifi,对比cubieboard,树莓派的配置容易得多,而且支持也更多. 较为官方的介绍配置为无线热点的文章莫过于这一篇<RPI-Wireless-Hotspot> 按照这个设置,我的其实不成功,于是找到这篇文章<Turn Your Raspberry Pi Into a WiFi Hotspot with Edimax Nano USB EW-7811Un (RTL8188CUS chipset)> 下面是我配置的过程,主要是hosta
