UIWebView的cookies存儲在哪裏？

Question

我正在用餅乾製作iPhone應用程序。在Safari設置中刪除Cookie不會刪除它們。他們在哪裏儲存？是否有可能從另一個UIWebView中讀取它們？

謝謝！

Answer 1

您的應用程序在[NSHTTPCookieStorage sharedHTTPCookieStorage]容器中有自己的「餅乾罐」。

這裏是你怎麼可能在你的應用程序的餅乾罐餅乾快速瀏覽一下：

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

有幾種方法可用於過濾和處理。查看訪問cookie的NSHTTPCookieStorage文檔以及訪問各個cookie屬性的NSHTTPCookie文檔。

感謝指針亞歷克斯！爲了補充這一點，我將放入使用Alex的例子創建的「cookie翻車機」。也許這會幫助別人。

- (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; 
}

亞歷克斯有一個關於把它放在一個類別的好主意。下面是我最終使用：

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 

使輸出更有點 「JSON-Y」 ......
