Loading PDF into UIWebView - Anything faster?
As the problem comes from network connectivity, you should display a loading bar while downloading the PDF so the user understands what is going on. Then, upon download completion, save the PDF in the documents folder of your app if the user wants to reopen it later

loading a UIWebView on second VC from another VC
Try creating the webview and loading the request in your initial viewController. Then pass that webView to your qrview. UIWebView *webview = [UIWebView alloc] init]; // or initWithFrame or whatever [webView loadRequest:request]; qrview.QRWebView = webView; That may not be exactly right, but that's the basic idea.

Loading a UIWebview when pressing a UIButton
The first thing to check is that the method is definitely being called. Are your NSLog statements being printed? If not, check that you have connected the button to the IBAction correctly in Interface Builder. I can't see anything in your code that is immediately jumping out to me as incorrect, so your best bet is to set a breakpoint at the start of the method and step through it line-by-line, checking the values of each variable as you go.

Slow loading UIWebView from string
This usually happens because of CSS used in rendering web page. It is default behavior when loading page locally. We can also consider that in first load, UIWebview doesn't have cache to this and create cache for that page. To make it little fast try loading page from a file e.g. NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"filePath" ofType:@"html" inDirectory:@"."]]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [webView loadRequest:request]; CSS like body { background-color:transparent; font-family:Arial-BoldMT; font-size:18;} also increase the time of loading a page.

page not loading in uiwebview storyboard
Check self.myWebView outlet connected self.myWebView get reinitialized anywhere after this loading EDIT. Ok the reason may be you are setting the url and loading in the webview ,But it is not initialized yet since the view is not yet loaded from nib.Pass the url string and store in an instance variable and in viewDidLoad method set the loadRequest with the value in instance variable Define an instance variable NSString *_urlToLoad; .m -(void)openDashboard:(NSString *) url { _urlToLoad =[url copy]; } -(void)viewDidAppear:(BOOL)animated { [self.myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:_urlToLoad]]]; }

UIWebView not loading local .html file
You are using a relative path (hence the blue color of a folder). You can actually find the answer to this problem here Load resources from relative path using local html in uiwebview or below: Drag the resource into your xcode project, you will get two options "create groups for any added folders" and "create folders references for any added folders". Select the "create folder references.." option. The code below should work. NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"/HTML"]]; [webView loadRequest:[NSURLRequest requestWithURL:url]];

Faster batch loading of nested data
I'm not as familiar with JdbcTemplate, but assuming it is similar to JDBC I would do it with something similar (I would probably break this into multiple methods) to the following code: private static final int BATCH_SIZE = 50; public void addBatch(Connection connection, List<Outer> outers) { PreparedStatement outerInsertStatement = connection.prepareStatement("...", Statement.RETURN_GENERATED_KEYS); PreparedStatement innerInsertStatement = connection.prepareStatement("...", Statement.RETURN_GENERATED_KEYS); List<Integer> outerIds = new ArrayList<Integer>(); for(Outer outer : outers) { outerInsertStatement.setParameter(...); ... outerInsertStatement.setParameter(...); outerInsertStatement.addBatch(); } outerInsertStatement.executeBatch()

Python reading faster on url and loading simplejson?
Probably the bottleneck is the multiple GET requests. You can probably achieve a significant speed-up by using the httplib library which gives you more control over the underlying connection. Try this: import httplib host = 'api.forecast.io' conn = httplib.HTTPSConnection(host) urlnyp = '/forecast/apikey/1.37871,103.848808' conn.request('GET', urlnyp) resultnyp = conn.getresponse() contentnyp = resultnyp.read() urltampines = '/forecast/apikey/1.353092,103.945229' conn.request('GET', urltampines) resulttampines = conn.getresponse() contenttampines = resulttampines.read() # ... conn.close()

How to improve ListView's loading time faster?
I did a few things to make it faster in loading the app. I am not sure which one is the solution. (1) I load all data from sql database including text and thumbnail images using AsyncTask. (2) I change thumbnail image format from png to jpg. (3) Then I clear the cache manually. The app looks like faster in loading, but sometimes it is still slow. Most of the times, it is faster than before. I am still making improvement to my app. Thanks

Is loading a blank image faster than multiple if statements?
Create an Object Pool with Images and load them on the initialization step. Load them in batches and extend pool with new images if required. While loading images show spinner. It will be loaded long for a first time, after that a browser will put them in cache. If you have an opportunity to combine different little images in one (sprite), do it! because it is faster to load one big image, then a lot of little.

In iOS 5.1 after dismissing MFMailComposeViewController my UIWebView page java script not working and not loading data from disc chache
I came across the same thing in iOS7 yesterday and found a solution a few minutes ago. Maybe it will help you. Check your viewWillDisappear method. Mine looked like this: - (void)viewDidDisappear:(BOOL)animated { [super viewDidDisappear:animated]; self.webView.delegate = nil; self.webView = nil; // whatever else you do } The error was in the assignments: when MFMailComposeViewController appeared and viewDidDisappear was called, webView lost its delegate and because of that clicks weren't captured. If you're programming for iOS6 or newer, you should just leave it like that: - (void)viewDidDisappear:(BOOL)animated { [super viewDidDisappear:animated]; // whatever else you do } But if you're programming for iOS5 or older and have to assign nil for some reason,

It should be faster, cProfile says it's faster, but the program actually runs slower
In your new implementation, you create 5 numpy arrays with each Brain object: self.h_activation = zeros((self.hidden_num, 1), dtype=float) self.o_activation = zeros((self.output_num, 1), dtype=float) self.i_output = zeros((self.input_num, 1), dtype=float) self.h_output = zeros((self.hidden_num, 1), dtype=float) self.o_output = zeros((self.output_num, 1), dtype=float) These attributes are not referenced in other parts of the code. Creating them is a potentially costly operation, which doesn't seem have a direct counterpart in the original implementation. I'm not sure that it would outweigh the speed advantage of faster numpy computations, but if you are creating a lot of Brain objects, it's something worth looking at.

Timer Gets Faster and Faster
Well, from what I understand, I dont see any line of code to stop previous timers that were setup by previously applied plugins, so I believe that they all stack up and the more you have at different intervals, the faster they get. Now, what you should be doing is detect if the plugin was previously applied on that element and if so, clear previously set timeouts. However, the way you designed your plugin, the options and other variables are shared, so they will be replaced everytime you apply the plugin on different elements. You will have to change this as well...

Checking if the data being retrieved from the database Eager loading OR lazy is loading
When you are using .Include() method you are initiating eager loading. So yes your data will be returned by single query. For checking it consider to use SQL Server Profiler or paid utility Entity Framework profiler. Also such utility as LinqPad could help you in query tracing Also you need to be careful with repositories returning IQueryable because usage like this will execute several queries in a loop: foreach(var accDef in repository.FindAccountDefinition(searchTerm)) { //get info from accDef }

"Failure loading DAC: CreateDacInstance failed" when loading dump file with ClrMD
I had similar problems with the initial release of ClrMD. It was unable to successfully load an MSCORDACWKS that WinDbg cheerfully accepted, was in the path I made available to ClrMD, and could successfully use with WinDbg against the same dump. The same thing happened with the initial release of DebugDiag v2 which, I understand, is based on ClrMD. I made the same renamed DAC accepted by WinDbg available on DebugDiag's symbol path and DebugDiag aborted the analysis; saying that the [provided] "mscordacwk.dlls’ timestamp and size do not match the one in the dump"; even though following the load attempt via ProcMon clearly showed it was accessing the correct DLL via the WinDbg-accepted name. However, while working with our Microsoft team on the DebugDiag v2 inability to load the DAC, I

Changing a jQuery loading bar so it doesn't redirect (Similar to Youtube new loading bar)
This seems like a silly way of doing an Ajax redirect. You don't want to load the new page completely, that's why Ajax should be really beneficial, because you only need to refresh the inner content. A better way of loading a page via Ajax would include: Make calls to the same URL when using Ajax and normal loads. Use your server side to pick up on the HTTP Header X-REQUESTED-WITH: XMLHTTPRequest, and if it's present, just send across the content. That way users without JavaScript can click on the same links and visit the standalone versions For newer browsers, you want to update the browser's URL without actually changing the page. This is best achieved using window.history.pushState (see here, but bear in mind that support for is very limited, particularly if your target audience are

Loading indicator stays in Firefox after iframe finished loading
Why are you triggering the write to the contentWindow by using the load event of the same iframe in the first place? An alternate approach just creates an iframe and loads some content with images into it - works on firefox as expected. No big deal. <!DOCTYPE html> <html> <head> <script type="text/javascript"> function createIframe(){ var f = document.getElementsByTagName('body') [0].appendChild(document.createElement('iframe')); f.contentWindow.document.write('<img src="http://www.funimage.org/uploads/posts/2013-02/1361892989_1_14.jpg" />'); } </script> </head> <body onload="createIframe()"> </body> </html>

That's a bad design.

UIWebview xml file
Set your UIWebView delegate and define webView:didFailLoadWithError: and – webViewDidFinishLoad:; if you put some NSLog traces in there (or break into them with the debugger), you might understand what is happening. In principle, if you can display a local file, you can display the same info coming from a remote server. So I am thinking that maybe your server is not replying correctly (and didFail: will help you understanding that). EDIT: The mimetype is sent by the server, and I am not aware of a way to modify it before the UIWebView gets to handle it. You can easily download a file by way of: NSData *urlData = [NSData dataWithContentsOfURL:url]; and then you can pass the data into the web view as you are already doing. Take into account that dataWithContentsOfURL: is sync, so i

How do I know when something has been pasted in a UIWebView?
Casting is not magic. I repeat: Casting is not magic! It does't change the run-time type of an object. If it didn't respond to a selector as a UIWebView, it won't respond to it as a UIMenuItem either. You have to detect the event using JavaScript and bridge your JavaScript function to Objective-C. Use the onpaste JavaScript event handler, then do something like what is described here: <!-- snippet from your HTML string --> <script type="text/javascript"> function call_objc_paste(text) { window.location.href = "fakescheme://" + text; } </script> <input type="text" onpaste="call_objc_paste(this.value);" /> // Objective-C code: webView.delegate = self; [webView loadHTMLString:htmlStr baseURL:nil]; - (BOOL) webView:(UIWebView *)wv s

This may not fix your problem, but try this. Change your PricesViewController.h and ReservationsViewController.h similarly. Also, what version of Xcode are you using, and what version of iOS are you targeting? You shouldn't need @synthesize in your .m if you're using a recent version of Xcode and iOS. @interface PricesViewController : UIViewController @property (nonatomic, weak) IBOutlet UIWebView *WebView; @end IBOutlets should not be retained, as this can cause retain cycles. May not be the cause, but good programming practice anyway.
