title="动态标签"></a>动态标签</h3><p>动态标签是我们在程序中，通过代码添加的，与之相关的类，主要有三个：</p><p>UIApplicationShortcutItem 创建3DTouch标签的类</p><p>UIMutableApplicationShortcutItem 创建可变的3DTouch标签的类</p><p>UIApplicationShortcutIcon 创建标签中图片Icon的类</p><p>3、响应标签的行为</p><p>类似推送，当我们点击标签进入应用程序时，也可以进行一些操作，我们可以看到，在applocation中增加了这样一个方法： </p><ul><li>( void )application:( UIApplication <em>)application performActionForShortcutItem:(UIApplicationShortcutItem </em>)shortcutItem completionHandler:( void (^)( BOOLsucceeded))completionHandler NS_AVAILABLE_IOS ( 9 _0);</li></ul><p>当我们通过标签进入app时，就会在appdelegate中调用这样一个回调，我们可以获取shortcutItem的信息进行相关逻辑操作。</p><p>这里有一点需要注意：我们在app的入口函数：</p><ul><li>( BOOL )application:( UIApplication <em>)application didFinishLaunchingWithOptions:( NSDictionary </em>)launchOptions;</li></ul><p>也需要进行一下判断，在launchOptions中有UIApplicationLaunchOptionsShortcutItemKey这样一个键，通过它，我们可以区别是否是从标签进入的app，如果是则处理结束逻辑后，返回NO，防止处理逻辑被反复回调。</p><p>几点注意：</p><p>1、快捷标签最多可以创建四个，包括静态的和动态的。</p><p>2、每个标签的题目和icon最多两行，多出的会用…省略</p><h2

<content type="html"><![CDATA[<h2 id="为什么使用FMDatabaseQueue"><a href="#为什么使用FMDatabaseQueue" class="headerlink" title="为什么使用FMDatabaseQueue"></a>为什么使用FMDatabaseQueue</h2><p>在实际的项目运行过程中，我们常常会遇到同一时刻有多个不同的线程请求数据库的访问。<br>举个简单的例子:</p><blockquote><p>假设当前线程1正在写数据库A，这时，线程2正好也要写数据库A，如果没有做线程安全处理，会造成很多数据没有如预期写入数据库。</p><p>假设当前线程1正在写数据库A，这时，线程2正好要读数据库A，如果没有做线程安全处理，会报”database is locked”错误。</p></blockquote><p>FMDB是对sqlite的封装，而文件数据库sqlite在同一时刻允许多个进程/线程读，但同一时刻只允许一个线程写。在进行写操作时，数据库文件会被琐定，此时任何其他读/写操作都被阻塞，如果阻塞超过5秒钟(默认是5秒，重新编译sqlite可以修改超时时间)，就报”database is locked”错误。 </p><p>如果线程使用单独的FMDatabase 实例是允许的，但是在多线程的环境下，不能多个线程共享一个FMDatabase对象，这样可能会造成数据的操作丢失，甚至引起程序的崩溃。</p><p>那么怎么做线程安全呢？使用FMDatabaseQueue。</p><p>FMDatabaseQueue可以比较有效的解决多线程下对数据库的访问,但是请注意不能在多个线程同时创建多个FMDatabaseQueue实例来操作同一个数据库。下面我们看下FMDatabaseQueue的用法和实现原理。</p><h2

title="FMDatabaseQueue实现原理"></a>FMDatabaseQueue实现原理</h2><p>FMDatabaseQueue通过内部创建一个Serial的dispatch_queue_t,来处理通过inDatabase和inTransaction传入的Blocks,会按顺序来执行它接收的Blocks。所以当我们在主线程（或者后台）调用inDatabase或者inTransaction时，代码实际上是同步的。</p><figure

id="特殊情况"><a href="#特殊情况" class="headerlink" title="特殊情况"></a>特殊情况</h2><p>如果在后台执行大量的更新操作时，主线程又需要执行少量的数据库操作(比如查询)，那么在后台操作执行完之前，它还是需要等待，这时就会阻塞主线程。下面是一些参考意见:</p><ul><li>如果在后台使用inDatabase来更新大批量的数据时，可以考虑使用inTransaction，因为后者的更新效率高很多，特别是更新大量操作（如1000条以上）</li><li>如果非必须一次性的、完整性的大批量数据，可以考虑使用数据拆解，将大量数据分成较多批少量的数据，再进行更新操作，这样能有效地避免长时间的阻塞</li><li>如果UI上不需要在更新数据时产生交互，可以将FMDatabaseQueue放入一个子线程中异步执行，这是一个不错的选择，反之，就需要考虑UI上的体验了，如加上一个UIActivityIndicatorView。</li></ul><figure
