没有缓存的UIWebview

Question

我想加载没有缓存的webview？

//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Request Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[kdgWebView loadRequest:requestObj];

Answer 1

Objective-C的:

// Remove and disable all URL Cache, but doesn't seem to affect the memory
[[NSURLCache sharedURLCache] removeAllCachedResponses];
[[NSURLCache sharedURLCache] setDiskCapacity:0];
[[NSURLCache sharedURLCache] setMemoryCapacity:0];

迅速:

URLCache.shared.removeAllCachedResponses()
URLCache.shared.diskCapacity = 0
URLCache.shared.memoryCapacity = 0

Answer 2

您可以使用以下代码更改缓存策略:

NSURLRequest *requestObj = [NSURLRequest requestWithURL:url 
                                        cachePolicy:NSURLRequestReloadIgnoringCacheData
                                    timeoutInterval: 10.0];
