以下是我的代码
nameLabel.text=[[[dict_Details objectForKey:@"unknown_object"] objectAtIndex:0] objectForKey:@"UserFullName"];

getUserReviewsResponse

"status_code" = 200;
"unknown_object" = "[{ID:227,ServiceProviderName:Dr.KarthikMendi,UserFullName:karthik,ReviewTemplateID:19,TotalScore:88.0,ServiceName:Doctor,Review:Very knowlegable doctor he understands the problem very well.,ServiceID:5,CommentsBySP:Thank you...,ServiceProviderID:0,CommentByAdmin:null,UserID:106,Status:true,CreatedDate:2016-05-06T18:30:08,Services:null,ServiceProviderTypes:null},{ID:168,ServiceProviderName:Dr.KarthikMendi,UserFullName:karthik,ReviewTemplateID:19,TotalScore:92.0,ServiceName:Doctor,Review:I am very impressed.

"unknown_object"的值是一个字符串，但您假设它是一个字典，因为您在其上调用objectForKey:。因此例外。
总的来说，我会说JSON是“破碎的”，因为它需要双重反序列化，这不太有用。

请检查http://jsoneditoronline.org/中的json数据是否正确。
例如：Dr.KarthikMendi是包括＆＃34; Dr.KarthikMendi＆＃34; （双重或单一报价）。
