NSURLRequest缓存问题iOS 7 [英] NSURLRequest cache issue iOS 7

问题描述

cachePolicy不起作用，它只是缓存下载的json。

in iOS 7 cachePolicy doesn't work, it just cache the downloaded json.

//URLRequest
        NSString *url = [NSString stringWithFormat:@"http://www.semhora.com/jsonparser/categories/categories_%d_test.json", _categoriesIndex];
        NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]
                                                  cachePolicy:NSURLCacheStorageNotAllowed
                                          timeoutInterval:60.0];

如何在iOS 7中禁止缓存？

How can I disallow cache in iOS 7?

推荐答案

我刚刚使用过：

//URLRequest
        NSString *url = [NSString stringWithFormat:@"http://www.semhora.com/jsonparser/categories/categories_%d_test.json", _categoriesIndex];
        NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]
                                                  cachePolicy:0
                                          timeoutInterval:60.0];

现在它有效，从苹果开发论坛得到任何答案，直到现在它为什么会发生。

And now it works, got any answer from apple dev forum until now why it happens.
