爲什麼有些Https url在WebView中不加載？

Question

爲什麼有些https鏈接不加載WebView。我可以看到一些https url在safari瀏覽器中加載完美，但是當我嘗試在webview中加載相同的url時，它不會加載。可能是因爲https有自簽名證書？我們不能加載具有自簽名證書的WebView中的url嗎？

編輯： 現在我能夠調用

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
{ 
    return YES; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge 
{ 
    [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; 
} 

不過我HTTPS URL中的WebView沒有加載。

試試這個：

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
{ 
    return YES; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { 
NSArray *trustedHosts = [NSArray arrayWithObjects:@"mytrustedhost",nil]; 

if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){ 
    if ([trustedHosts containsObject:challenge.protectionSpace.host]) { 
    [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; 
    } 
} 
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge]; 
}
