如何使用NSJSONSerialization类参考读取JSON文件？ [英] How to read a JSON file using the NSJSONSerialization Class Reference?

问题描述

我需要使用NSJSONSerialization类参考读取JSON文件，我发现的有关此类使用的所有示例都从网页本身读取内容，而不是从先前创建的JSON文件中读取.Anyone知道如何使用该类从JSON文件解析？谢谢。

I need to read a JSON file using the NSJSONSerialization Class Reference, and all the examples that I have found about the use of this class read the content from the webpage itself, instead of reading from a JSON file that has been previously created.Anyone knows how to parse from a JSON file using that class? Thanks.

推荐答案

简单，快速的例子：

NSString *jsonPath = [[NSBundle mainBundle] pathForResource:@"foobar"
                                                     ofType:@"json"];
NSData *data = [NSData dataWithContentsOfFile:jsonPath];
NSError *error = nil;
id json = [NSJSONSerialization JSONObjectWithData:data
                                          options:kNilOptions
                                            error:&error];
NSLog(@"JSON: %@", json);
