iOS: Adjust Height of UIWebView - Strange Behaviour

I have a question. In Xcode I have a ViewController with embed View > ScrollView and inside of the Scrollview is a UIWebView.

The application reads some XML data und paste formatted text into the UIWebView. After the UIWebView-Element is another Element, so I have to adjust the height of the UIWebView dynamically.

After loading the view everything is fine, but when i tap on the screen the view re-size the scrollview to its storyboard height.

Why ?

- (void)webViewDidFinishLoad:(UIWebView *)aWebView
{
aWebView.scrollView.scrollEnabled = NO;    // Property available in iOS 5.0 and later
CGRect frame = aWebView.frame;

frame.size.width = 280;       // Your desired width here.
frame.size.height = 1;        // Set the height to a small one.

aWebView.frame = frame;       // Set webView's Frame, forcing the Layout of its embedded     scrollView with current Frame's constraints (Width set above).

frame.size.height = aWebView.scrollView.contentSize.height;  // Get the corresponding         height from the webView's embedded scrollView.

aWebView.frame = frame;       // Set the scrollView contentHeight back to the frame itself.

NSLog(@"size: %f, %f", aWebView.frame.size.width, aWebView.frame.size.height);

// Position URL Label
CGRect frame_label = fachmesseDetailWebsite.frame;
NSLog(@"x: %f", frame_label.origin.x);
NSLog(@"y: %f", frame_label.origin.y);
frame_label.origin.y=aWebView.frame.size.height+115;//pass the cordinate which you want
frame_label.origin.x= 20;//pass the cordinate which you want
fachmesseDetailWebsite.frame= frame_label;
NSLog(@"x: %f", frame_label.origin.x);
NSLog(@"y: %f", frame_label.origin.y);

}

whenever you are changing the frame you have to reload the webview then only webview frame will change whatever you put there other wise it doesn't effect on webview.

[webview reload];

EDIT: this one working

UIWebView *web=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];

    NSString* html = [NSString stringWithFormat:@"<html><head><style>a { color: #db5226; text-decoration: none; font-weight: bold; } body { padding: 0; margin: 0; font-size:45px;font-family: Helvetica;text-align:left; color:black; } </style></head<body>%@</body></html>",@"helow"];
    [web loadHTMLString:html baseURL:nil];
    [self.view addSubview:web];
