WebView本地CSS

Question

如何加載網頁，例如： google.com，然後加載一個覆蓋某些樣式的本地CSS文件？

我能做的第一部分，我似乎無法做到的是後者。

Answer 1

像往常一樣，答案非常簡單。

WebPreferences *webPrefs = [WebPreferences standardPreferences]; 
[webPrefs setUserStyleSheetEnabled:YES]; 
//Point to wherever your local/custom css is 
[webPrefs setUserStyleSheetLocation:[[NSBundle mainBundle] URLForResource:@"style" withExtension:@"css"]]; 

//Set your webview's preferences 
[myWebView setPreferences:webPrefs]; 

Answer 2

我想在這裏做同樣的事情，除了我的情況，我想從我的OS X目錄中的特定目錄加載它。

NSFileManager *fileManager = [NSFileManager defaultManager]; 
WebPreferences *webPrefs = [WebPreferences standardPreferences]; 
[webPrefs setUserStyleSheetEnabled:YES]; 
NSString *folder = @"~/Library/Application Support/irccloud/Style/"; 
folder = [folder stringByExpandingTildeInPath]; 

if ([fileManager fileExistsAtPath:folder] == NO) { 
    [fileManager createDirectoryAtPath:folder withIntermediateDirectories:YES attributes:nil error:NULL]; 
} 
//Point to wherever your local/custom css is 
NSURL *fileURL = [NSURL fileURLWithPath:@"/Users/ali/Library/Application Support/irccloud/Style/style.css"]; 
[webPrefs setUserStyleSheetLocation:fileURL]; 
//Set your webview's preferences 
[webView setPreferences:webPrefs];

在斯威夫特：

// Now kick start css 
    let ourWebPrefs:WebPreferences = WebPreferences.standardPreferences(); 
    ourWebPrefs.userStyleSheetEnabled = true; 
    ourWebPrefs.userStyleSheetLocation = NSBundle.mainBundle().URLForResource("webview", withExtension: "css"); 
    customWebView.preferences = ourWebPrefs;
