说明:目前为止我找到三种查找与替换功能,如果有更多的方式,请在下面留言 第一种:我们常用的查找以及查找与替换功能 在Windows下,使用Ctrl+f 快捷键查找.用Ctrl+h来进行查找与替换功能. 在Xcode下,我们使用CMOMAND+Shift+F来进行查找,用Command+Shift+Alt+F快速进行查找与替换. 注意图上的“Find”.“Text”.“Contain”均可以点击,并且换成其他的条件.比如从Find换成Replace,后面的Contain也可以换成其他的形式,比如字…

编写Hello World应用程序通常被觉得,是学习不论什么编程语言的第一步.在这一章,你将创建iOS版的Hello World应用程序作为起步,高速了解Xcode这个开发iOS应用程序的主要工具.      下一步.你将学习Objective-C的基础知识.在此基础之上.将探索类(class)与对象(object)的知识.它们是构建应用程序的主要基石.与此同一时候,你将创建CarValet应用程序,练习一些类的编写.并学习属性(property)的知识.在本章末尾,你将在指导下完毕编程挑战题以…

463. Island Perimeterhttps://leetcode.com/problems/island-perimeter/就是逐一遍历所有的cell,用分离的cell总的的边数减去重叠的边的数目即可.在查找重叠的边的数目的时候有一点小技巧,就是沿着其中两个方向就好,这种题目都有类似的规律,就是可以沿着上三角或者下三角形的方向来做.一刷一次ac,但是还没开始注意codestyle的问题,需要再刷一遍. class Solution { public: int islandPerime…

class Array Arrays are ordered, integer-indexed collections of any object. Array indexing starts at 0, as in C or Java. A negative index is assumed to be relative to the end of the array—that is, an index of -1 indicates the last element of the array…
