在UIWebView下，可以使用

[[NSURLCache sharedURLCache] removeAllCachedResponses];//清除緩存

WKWebView清除cookies的方法（iOS9以上）

WKWebsiteDataStore *dateStore = [WKWebsiteDataStore defaultDataStore]; 
  [dateStore fetchDataRecordsOfTypes:[WKWebsiteDataStore allWebsiteDataTypes] 
           completionHandler:^(NSArray<WKWebsiteDataRecord *> * __nonnull records) { 
             for (WKWebsiteDataRecord *record in records) 
             { 
//               if ( [record.displayName containsString:@"baidu"]) //取消備注，可以針對某域名清除，否則是全清 
//               { 
                 [[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:record.dataTypes 
                                      forDataRecords:@[record] 
                                    completionHandler:^{ 
                                      NSLog(@"Cookies for %@ deleted successfully",record.displayName); 
                                    }]; 
//               } 
             } 
           }]; 

iOS9一下用這種方法：

NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
NSString *cookiesFolderPath = [libraryPath stringByAppendingString:@"/Cookies"]; 
NSError *errors; 
[[NSFileManager defaultManager] removeItemAtPath:cookiesFolderPath error:&errors]; 

查看cookie

NSHTTPCookie *cookie;
NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [cookieJar cookies]) {
  NSLog(@"%@", cookie);
}
