在mac 10.9上，Safari首选项plist不会从用户默认值更改

Question

我在更改"Block cookies and other website data:“表单隐私时遇到了Mac中的首选项缓存问题。我尝试使用用户默认设置来更改首选项。当“从不”选项被选中时，它将变为“来自第三方和广告商”。但是如果“总是”选择更改，它就不起作用了。OSX版本为10.3

defaults write com.apple.Safari.ContentPageGroupIdentifier.WebKit2StorageBlockingPolicy 1(默认写入com.apple.Safari 1)

defaults write com.apple.Safari WebKitStorageBlockingPolicy 1

遵循此链接http://hotdigitalnews.com/how-to-tackle-defaults-not-sticking-in-mavericks/中给出的相同步骤

-(IBAction)allowCookies：(Id)发送者{

[self quitApplicationIfRunning:@"com.apple.Safari"];
[self setCookies];

NSString *text =nil;
NSString *commandString = [NSString stringWithFormat:@"defaults write com.apple.WebFoundation NSHTTPAcceptCookies 'always' "];
text = [self runAsCommand:commandString];
NSLog(@"text %@",text);
[self manageCookies:0];

}

-(空)setCookies{

NSLog(@"Cookies has been changed %lu",[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookieAcceptPolicy]);
[[NSHTTPCookieStorage sharedHTTPCookieStorage]  setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

[[NSNotificationCenter defaultCenter] postNotificationName:NSHTTPCookieManagerAcceptPolicyChangedNotification object:self userInfo:nil];

}

-(空)manageCookies：(短)选项{

NSString *commandString = [NSString stringWithFormat:@"defaults write com.apple.Safari com.apple.Safari.ContentPageGroupIdentifier.WebKit2StorageBlockingPolicy -int %d",option];

NSString *text = [self runAsCommand:commandString];
NSLog(@"text %@",text);

commandString = [NSString stringWithFormat:@"defaults write com.apple.Safari WebKitStorageBlockingPolicy -int %d",option];

text = [self runAsCommand:commandString];
NSLog(@"text %@",text);

}

• (NSString*)runAsCommand:(NSString *)字符串{
