开发中各种错误汇总

一.

1. couldn’t be opened because you don’t have permission to view it.

一般是由于导入了第三方除了冲突,只要clean 一下工程后再运行即可.

---

2.在控制台中报了content-type: text/plain错误,则在自己的manage文件中添加text/plain

text/json 或者text/JavaScript 等相似错误也是一样的解决方法
但是系统只默认最后添加的一条配置

---

3. 控制台输出不是中文,要转成中文输出

直接添加下面代码文件(创建 Objective-C File 的空文件)

4. 跳转 App Store 没有反应

替换中文:
