URL

Get current URL using JavaScript

UIWebView+URL.h

#import <UIKit/UIKit.h>

@interface UIWebView (URL)

@property (nonatomic, readonly) NSString *URLString;
@property (nonatomic, readonly) NSURL *URL;

@end

UIWebView+URL.m

#import "UIWebView+URL.h"

@implementation UIWebView (URL)
- (NSString *)URLString {
    return [self stringByEvaluatingJavaScriptFromString:@"document.URL"];
}
- (NSURL *)URL {
    return [NSURL URLWithString:self.URLString];
}
@end

Display about:blank

[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"about:blank"]]];

Delete Cookie

NSHTTPCookieStorage *cookieStrage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (id obj in [cookieStrage cookies]) {
  [cookieStrage deleteCookie:obj];
}

Clear Cache

NSURLCache *cache = [NSURLCache sharedURLCache];
[cache removeAllCachedResponses];

timeout

timeout setting is from NSURLRequest not UIWebView.
