关于Xcode的代码块

关于Xcode的代码块,我感觉应该是这个编译器里最好用的部分的,用的好的话对你开发的速度是成十倍百倍的效率提升。期间也转用过AppCode,最终还是用回Xcode,转回来又两个主要原因,首先还是被流畅度给打败了,其次虽然我也觉得idea他们公司编译器的快捷键也很强大确实也很好用,但是我还是喜欢这个代码块,对我个人来说简直就是神器。

很早之前也研究过AppCode有没有这样可以高度自定义的代码块功能,但是没有研究出来,如果有知道的大神请在评论区教一教我。。。

  将近3年的Xcode的使用经验,我自己多少也总结了不少自己常用的代码块,请将目光向下移动。

  • 快速创建数组属性

  • 截取系统侧滑手势[备注:有些特殊情况下需要禁用掉系统的侧滑功能,但是有的时候直接禁用nav的侧滑手势在某些可能下会造成系统的假死(我遇到过很多次),所以,这是我经常使用的方法],这个方法就是通过添加手势来截断系统的手势。
