Question

我的代码出了什么问题？

我在google上查看了有关错误的更多信息，但找不到任何解决方案。谁能帮我解决这个问题呢？

错误发生在以下几行：

self = [self initWithName：dic [@＆＃34; name＆＃34;] thumbnail：dic [@＆＃34; thumbnail＆＃34;] 电子邮件：DIC [@＆＃34;电子邮件＆＃34;]];
self = [self initWithName：@＆＃34; Undifined＆＃34; 缩略图：@＆＃34; Undifined＆＃34;电子邮件：@＆＃34; Undifined＆＃34;];

Contact没有声明该方法，就像警告所说的那样。它声明initWithName:thumbnail:photo。

没有可见的@interface用于＆＃39;联系＆＃39;声明选择器＆＃39; initWithName：thumbnail：email：＆＃39;
