出於某種原因,第一種方法不顯示任何內容,而第二個作用:stringWithContentsOfFile工作,但requestWithURL不
//Common
NSString *path=[[NSBundle mainBundle] pathForResource:@"about" ofType:@"html"];
//Method1
[webView loadRequest:[NSURLRequest requestWithURL: [NSURL fileURLWithPath: path isDirectory: NO]]];
//Method 2
NSString *HTML=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:NULL];
[webView loadHTMLString:HTML baseURL:[NSURL URLWithString:[[NSBundle mainBundle] bundlePath]]];
//Common
UIViewController* controller=[webView controllerWithTitle:@"Help"];
[delegateRef.navController pushViewController:controller animated:YES];
在另一方面,我也嘗試使用URL作爲加載它好。同樣,第一種方法在第二種方法中沒有顯示任何內容。
//Common
NSURL *url=[[NSBundle mainBundle] URLForResource:@"about" withExtension:@"html"];
//Method 1
[webView loadRequest:[NSURLRequest requestWithURL:url]];
//Method 2
NSString *HTML=[NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:NULL];
[webView loadHTMLString:HTML baseURL:[NSURL URLWithString:[[NSBundle mainBundle] bundlePath]]];
奇怪的是,如果我改變URL,如下所示,那麼這兩個方法的工作(當然加載字符串不顯示CSS):
NSURL *url=[NSURL URLWithString:@"http://www.google.com"];
controllerWithTitle
是在一個類別定義如下:
-(UIViewController*) controllerWithTitle:(NSString*)title{
UIViewController *vc=[[[UIViewController alloc] init] autorelease];
vc.view=self;
vc.title=title;
return vc;
}
