objective-c 开发最简单的UITableView时数据进不去的问题

今天在使用UITableView时遇到的问题,我在plist文件配置的数据进不去列表,以下是解决方案

问题原因:plist文件root的type配置错误 

如上图所示,博主是使用plist文件作为我的沙盒,if Root's Type 为array时

1 self.simpleData = [[NSArray alloc] initWithContentsOfFile:filePath];
2 
3 self.simpleData=[NSArray arrayWithContentsOfFile:filePath];

上面的第一行与第三行代码任选其一就可以

如果type为Dictionary时

 NSMutableDictionary *data = [[NSMutableDictionary alloc]
                                initWithContentsOfFile:filePath];

利用这种方式将plist文件位置传进去就行。
