我将设备升级到iOS 9.
该设备将无法在Xcode 7.1中运行,在绑定运行时会收到错误:
在此设备上启用开发时遇到错误.请尝试重新启动并重新连接设备.(0xE8000076)
所以我按照这里的建议更新了iTunes并下载了Xcode 7.0,进行了清理和构建.没运气.

我正在使用文件手提包PNG和JPEG从解析下载图像.

我使用多维数组来存储特定销售人员(1到4个销售人员)销售的产品总量(产品范围1到5).
T在第1行到第4行中安排了salesPersons,在第1列到第5列中安排了产品ID.
我唯一不能做的就是遍历各行以获得每个产品的总数,即第1列:第1行到第4行的总和=总产品1,第2列:第1行到第4行的总和=产品2总数等.
