importClass

导入Objective-C类对象

<span style="background-color:#333333"><span style="color:#474747"><code>
<span style="color:#98fb98">ClassObject</span><span style="color:#ffffff"> plus</span><span style="color:#ffffff">.</span><span style="color:#ffffff">ios</span><span style="color:#ffffff">.</span><span style="color:#ffffff">importClass</span><span style="color:#ffffff">(</span> <span style="color:#98fb98">String</span><span style="color:#ffffff"> classname </span><span style="color:#ffffff">);</span>
				</code></span></span>

说明：

导入类对象后，就可以通过.操作符直接调用对象（类对象/实例对象）的方法。通过.操作符号调用方法时，不需要使用":"来分割参数。注意：导入类对象将会消耗较多的系统资源，不应该导入过多的类对象，可以使用plus.ios.invoke()来调用未导入类实例对象的方法。

参数：

classname: ( String | InstanceObject ) 必选 要导入的Objective-C类名
如果指定的类名不存在，则导入类失败，不会抛出异常。

返回值：

ClassObject : Objective-C类对象，如果导入类对象失败则返回null。
