UIWebView 的 cookie 存储在哪里？

Your application has its own "cookie jar" in the [NSHTTPCookieStorage sharedHTTPCookieStorage] container.

Here's how you might take a quick look at the cookies in your application's cookie jar:

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

Several methods are available for filtering and manipulation. Take a look at the NSHTTPCookieStorage documentation for accessing cookies, and the NSHTTPCookie documentation for accessing individual cookie properties.

Thanks for the pointer Alex! To add to this I will drop in my "cookie dumper" that I created using Alex's example. Maybe this will help someone else.

- (void) dumpCookies:(NSString *)msgOrNil {
NSMutableString *cookieDescs    = [[[NSMutableString alloc] init] autorelease];
NSHTTPCookie *cookie;
NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [cookieJar cookies]) {
[cookieDescs appendString:[self cookieDescription:cookie]];
}
NSLog(@"------ [Cookie Dump: %@] ---------\n%@", msgOrNil, cookieDescs);
NSLog(@"----------------------------------");
}


- (NSString *) cookieDescription:(NSHTTPCookie *)cookie {


NSMutableString *cDesc      = [[[NSMutableString alloc] init] autorelease];
[cDesc appendString:@"[NSHTTPCookie]\n"];
[cDesc appendFormat:@"  name            = %@\n",            [[cookie name] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[cDesc appendFormat:@"  value           = %@\n",            [[cookie value] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[cDesc appendFormat:@"  domain          = %@\n",            [cookie domain]];
[cDesc appendFormat:@"  path            = %@\n",            [cookie path]];
[cDesc appendFormat:@"  expiresDate     = %@\n",            [cookie expiresDate]];
[cDesc appendFormat:@"  sessionOnly     = %d\n",            [cookie isSessionOnly]];
[cDesc appendFormat:@"  secure          = %d\n",            [cookie isSecure]];
[cDesc appendFormat:@"  comment         = %@\n",            [cookie comment]];
[cDesc appendFormat:@"  commentURL      = %@\n",            [cookie commentURL]];
[cDesc appendFormat:@"  version         = %d\n",            [cookie version]];


//  [cDesc appendFormat:@"  portList        = %@\n",            [cookie portList]];
//  [cDesc appendFormat:@"  properties      = %@\n",            [cookie properties]];


return cDesc;
}

Alex had a great idea about putting this in a category. Here's what I ended up using:

NSHTTPCookieStorage+Info.h

#import <Foundation/Foundation.h>


@interface NSHTTPCookieStorage (Info)


+ (NSDictionary*) describeCookies;
+ (NSDictionary *) describeCookie:(NSHTTPCookie *)cookie;


@end

NSHTTPCookieStorage.m

@implementation NSHTTPCookieStorage (Info)


+ (NSDictionary*) describeCookies {
NSMutableDictionary *descriptions = [NSMutableDictionary new];


[[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies] enumerateObjectsUsingBlock:^(NSHTTPCookie* obj, NSUInteger idx, BOOL *stop) {
[descriptions setObject:[[self class] describeCookie:obj] forKey:[[obj name] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
}];


NSLog(@"Cookies:\n\n%@", descriptions);
return descriptions;
}


+ (NSDictionary *) describeCookie:(NSHTTPCookie *)cookie {
return @{@"value" : [[cookie value] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
@"domain" : [cookie domain] ? [cookie domain]  : @"n/a",
@"path" : [cookie path] ? [cookie path] : @"n/a",
@"expiresDate" : [cookie expiresDate] ? [cookie expiresDate] : @"n/a",
@"sessionOnly" : [cookie isSessionOnly] ? @1 : @0,
@"secure" : [cookie isSecure] ? @1 : @0,
@"comment" : [cookie comment] ? [cookie comment] : @"n/a",
@"commentURL" : [cookie commentURL] ? [cookie commentURL] : @"n/a",
@"version" : @([cookie version]) };


}


@end

Makes the output a bit more "JSON-y"...

in sandbox:Library->Cookies->Cookies.binarycookies but you can not open the .binarycookies directly, you can run a script:

1. Download and install Python

2. Download BinaryCookieReader.py

3. Run "Python BinaryCookieReader.py" on the terminal

as you can see, output log contains detail cookies description
