Answer 1

如果我正确理解你的问题，包含逗号分隔的URL字符串，并要提取他们。

可以很容易地实现这一点使用NSString的方法componentsSeparatedByString，例如

NSString *uploadImages = response[@"upload_images"]; 
NSArray *imageURLs = [uploadImages componentsSeparatedByString:@", "]; 

其中I假定response是一个NSDictionary物体保持所解析响应。

Answer 2

你可以得到的"upload_images"为string，并且可以在array使用componentsSeparatedByString:方法

NSString *uploadImages = [response objectForKey:@"upload_images"]; 
NSArray *imageUrlArray = [uploadImages componentsSeparatedByString:@", "];
