Which way is faster to load page in uiwebview - iphone

Question

Which way is faster to load webpages in uiwebivew
using
Loading NSData into a UIWebView
OR
using Load Request URL?

Answer 1

Network requests take time. There's no point in trying to optimize a few milliseconds off this type of code. Write the code that is most readable / maintainable and it will serve you better.
You could put the webpage, scripts, css, and images in your app bundle; get a URL that points to it (file://...) and use that. Within your webpage, you can use AJAX to pull in some dynamic data, etc.
That'd be a better path to optimize; but it all depends on your situation.
If you have the option of using loadRequest, I'd recommend it. Let the OS take the work off your hands.
edit:
PS: UIWebView tends to take it's time about displaying data; even when no network is involved.
I often set the webview's alpha to 0 in IB or viewDidLoad; then fade it in when the content is ready.
Inside your webViewDidFinishLoad: method, add this:
if (0.0f == webview.alpha) {
[UIView animateWithDuration:0.4f
animations:^{
webview.alpha = 1.0f;
}];
}

Answer 2

Their is really isn't any "technical" way to load Webview faster, But I would recommend you use:
Load Request URL
Load Request URL Code:
#interface WebViewController : UIViewController {
IBOutlet UIWebView *webView;
}
#property (nonatomic, retain) UIWebView *webView;
#end
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
- (void)viewDidLoad {
NSString *urlAddress = #"http://www.google.com";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Request Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[webView loadRequest:requestObj];
}
