type:link

Linkのタイトルの下にボタンを置いてタッチすると必要最低限のコントローラを持ったUIWebView（を持ったUIViewController）をaddSubViewして用済みになればkillmeするクラスを作って貼った。特に問題なく稼働。

- (id)initWithURL:(NSString *)string{
 self=[super init];if(self) url=string;
 return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
 // Do any additional setup after loading the view.
 page=[[UIWebView alloc]initWithFrame:self.view.bounds];page.scalesPageToFit=YES;page.delegate=self;[self.view addSubview:page];
 toolbar=[[UIToolbar alloc]initWithFrame:CGRectMake(0, self.view.frame.size.height-36, self.view.frame.size.width,36)];
 toolbar.tintColor=[UIColor blackColor];toolbar.translucent=YES;
 [self.view addSubview:toolbar];
 back=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemRewind target:self action:@selector(back)];
 forward=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFastForward target:self action:@selector(forward)];
 done=[[UIBarButtonItem alloc]initWithTitle:@"done" style:UIBarButtonItemStyleDone target:self action:@selector(killme)];
 NSArray *buttons=[[NSArray alloc]initWithObjects:done,back,forward,nil];
 [toolbar setItems:buttons animated:YES];
 [page loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];
}

- (void)webViewDidStartLoad:(UIWebView *)webView{
 if(!ai) ai=[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
 [ai setCenter:self.view.center];[self.view addSubview:ai];[ai startAnimating];
 [self update];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView{
 if(ai) [ai removeFromSuperview];
 [self update];
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{
 //nothing.
}
- (void)update{
 back.enabled=page.canGoBack;
 forward.enabled=page.canGoForward;
}

- (void)killme{[self.view removeFromSuperview];}
- (void)back{if(page.canGoBack)[page goBack];}
- (void)forward{if(page.canGoForward)[page goForward];}

できた。まあこのへんは参考にできる文書が山のようにあるので楽チン。残すはchat、audio、videoか。なんとかなるかな。
昼は3738＠長居で特製中華そば。ガラガラ。思ってたよりは美味しかった。今月まだ１０杯目。
