Wrong CacheModel at iOS Version

[Jin]

at iOS ， WebPreferences store at NSUserDefault, and load when it invloke - (instancetype)initWithIdentifier:(NSString *)anIdentifier sendChangeNotification:(BOOL)sendChangeNotification 。

However，I got found a bug .

I store "WebKitCacheModelPreferenceKey" for value "2" to NSUserDefault and restart my Application.

then call the following code:

WebCacheModel settingMode = [[WebPreferences standardPreferences] cacheModel];
WebCacheModel webViewMode =[WebView _cacheModel];

assert(settingMode  == webViewMode);// not the same value.  settingMode  is "2" ,but  webViewMode  is "0".



I think the problem maybe at "+ (WebPreferences *)standardPreferences".

It sholud  change the following code:

_standardPreferences = [[WebPreferences alloc] initWithIdentifier:nil sendChangeNotification:NO];

to

_standardPreferences = [[WebPreferences alloc] initWithIdentifier:nil sendChangeNotification:YES];
