有没有办法让用户在使用浏览器在javascript svg画布上创建矢量图后,将该文件下载到本地文件系统?
SVG对我来说是一个全新的领域,如果我的措辞不准确,请耐心等待.
可能这很简单,但我找不到为Xcode 6中的目标定义预处理器宏的方法.
我有一个包含Nd数据的1d数组,我想用std :: transform或std :: for_each有效地遍历它.
unigned int nelems;
unsigned int stride=3;// we are going to have 3D points
float *pP;// this will keep xyzxyzxyz...
Load(pP);
std::transform(pP, pP+nelems, strMover<float>(pP, stride));//How to define the strMover??

我正在构建一个CoreLocation基于应用程序的应用程序,该应用程序根据纬度,经度,水平精度,海拔高度,垂直精度,行进距离等6个参数向用户显示其位置.
它假设要求用户允许第一次访问位置,但我也尝试重置所有模拟器的设置.
