<p>说他坑主要集中在获取他的height上，需要先sizetofit确定frame后获取height。<br>第二坑是searchVC.definesPresentationContext设为No后要手动把active设为no才能跳转<br>第三坑是改变背景色，这样方式比较暴力，在想没有更好的办法<br>第四坑是直接searchBgView=searchVC.searchBar无效，要在view上再加一层view，将他设为<br>searchVC.searchBar才有效。<br>第五坑搜索结果后push新页面时搜索结果页在最上面，需要设置self.definesPresentationContext = YES;<br>第六坑，搜索激活后，点击tabbar切换控制器 在点tabbar返回 发现searchVC被导航栏覆盖了，暂时解决方法，点击其他tabbar的时候active设为NO，并且要重置下searchVC.searchbar的frame，不然会错位，这也是个坑</p>
<p>为了要个UISearchController的动画效果，踩得坑还真是不少。</p>

<p>最近有个任务是写日历，记录一下遇到的坑，获取星期返回的数字，从星期日开始，星期六结束，对应数字1-7.</p>
<p>计算“yyyy-MM-dd”的时间戳是在当天0点，如果要获取这天结尾需要+1天。</p>
<p>遍历整个日历是直接遍历整个collectionview的indexpath，不要分区遍历，不然头尾衔接不上</p>
<p>关于合并两个相邻日期的详情文字，只有覆盖一层view，通过遍历整个collectionview的indexpath，获取需要遍历的indexpath，然后计算坐标，在到maskview上添加合并的文字，并取消collectionview里的文字。</p>

<p>最新有一个新需求，要求用户把文章内容能加入到他的笔记里，但是不能复制外面，所以系统的复制粘贴功能要禁用，我就想到了用YYTextView来做选择复制的功能，但是他的功能没有自定义UIMenuController的接口，所以要改他的源码，所以稍微阅读了下YYTextView的源码，实现了自定义UIMenuController的功能。</p>
<p>第一步、在YYTextView.h文件里添加接口</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line">//自定义menu菜单</span><br><span class="line">@property (nonatomic, strong) NSArray<UIMenuItem *> *menuItems;</span><br><span class="line">//隐藏菜单 这两个是他自己隐藏的接口，暴露出来，有地方会用到</span><br><span class="line">- (void)_hideMenu;</span><br><span class="line">- (void)_hideMagnifier;</span><br><span class="line">//禁止所有的menu菜单</span><br><span class="line">@property (nonatomic, assign) BOOL forbidMenu;</span><br></pre></td></tr></table></figure>
<p>第二步，在.m里添加实现<br>在_showMenu这个方法里</p>
<p>在初始化menu的地方添加</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line">if (self.menuItems.count > 0) {</span><br><span class="line"> menu.menuItems = self.menuItems;</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>在这个方法- (BOOL)canPerformAction:(SEL)action withSender:(id)sender里添加<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br></pre></td><td class="code"><pre><span class="line">if (self.forbidMenu == YES) {</span><br><span class="line"> return NO;</span><br><span class="line"> }</span><br><span class="line"> if (self.menuItems.count > 0) {</span><br><span class="line"> return NO;</span><br><span class="line"> }</span><br></pre></td></tr></table></figure></p>
<p>第三步，实现items</p>
<p>在你要用YYTextView的地方添加items</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line">UIMenuItem *cancelItem = [[UIMenuItem alloc]initWithTitle:@"取消" action:@selector(cancelMenuItem:)];</span><br><span class="line"> UIMenuItem *addNoteItem = [[UIMenuItem alloc]initWithTitle:@"加入到笔记" action:@selector(addNoteMenuItem:)];</span><br><span class="line"> textview.menuItems = @[cancelItem,addNoteItem];</span><br></pre></td></tr></table></figure>
<p>同样重写</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br></pre></td><td class="code"><pre><span class="line">- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {</span><br><span class="line"> if (action == @selector(cancelMenuItem:)) {</span><br><span class="line"> return YES;</span><br><span class="line"> } else if (action == @selector(addNoteMenuItem:)) {</span><br><span class="line"> return YES;</span><br><span class="line"> }</span><br><span class="line"> return NO;</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>最后实现@selector(cancelMenuItem:) 和 @selector(addNoteMenuItem:) 方法就行了</p>
<p>效果:</p>

<p>最近有个需求需要记录用过的viewcontroller，所以打算用yycache来缓存，然后发现缓存倒是缓存了，但是再取出来的viewcontroller的地址都变了，而且是每取一次变一次。</p>

<p>4.修改TemplateInfo.plist里的值<br><img src="https://raw.githubusercontent.com/wqforever/wqforever.github.io/master/image/6466C6A5-1980-420B-8477-842E3079A70A.png" alt="Alt Text"></p>
<p><strong>踩下的坑：创建文件和修改plist先把文件复制到桌面创建修改好在替换里面的文件，直接修改里面的文件是不行的，即使把权限修改为读写也不行</strong></p>
