iOS提问：'-[__NSCFDictionary icon]:

Question

就是在viewcontroller.m里面写的九宫格界面，在从.plist文件中加载、、imageview和label的内容时报错，但是下方按钮的图片能加载出来。铜鼓这顶背景颜色也能发现其实能读出plist文件中具体有几个对象。但是就是加载不出来图片和label的值
具体报错如下

我已经自己解决了
把添加模块的部分改成如下代码即可顺利运行
[self.view addSubview:appView];
AppModel *appModle = self.apps[i];
替换成：
因为返回值和接收的对象搞得类型不匹配
[self.view addSubview:appView];
AppModel *appModle = [AppModel appModelWithDict:self.apps[i]];
就这样，
