  • Is there a CSS library which mimics the iPhone grouped UITableView?

    - by cannyboy
    Is there a CSS library which mimics the iPhone grouped UITableView? I want to build a nice looking table which looks exactly like the grouped UITableView. As there are multiple text styles within the each line of text, and I don't need any interactivity except scrolling, it seems it would be easier to build with HTML and display it in a UIWebView. Is there a css library which matches this need?

  • Are Large iPhone Ping Times Indicative of Application Latency?

    - by yar
    I am contemplating creating a realtime app where an iPod Touch/iPhone/iPad talks to a server-side component (which produces MIDI, and sends it onward within the host). When I ping my iPod Touch on Wifi I get huge latency (and a enormous variance, too): 64 bytes from 192.168.1.3: icmp_seq=9 ttl=64 time=38.616 ms 64 bytes from 192.168.1.3: icmp_seq=10 ttl=64 time=61.795 ms 64 bytes from 192.168.1.3: icmp_seq=11 ttl=64 time=85.162 ms 64 bytes from 192.168.1.3: icmp_seq=12 ttl=64 time=109.956 ms 64 bytes from 192.168.1.3: icmp_seq=13 ttl=64 time=31.452 ms 64 bytes from 192.168.1.3: icmp_seq=14 ttl=64 time=55.187 ms 64 bytes from 192.168.1.3: icmp_seq=15 ttl=64 time=78.531 ms 64 bytes from 192.168.1.3: icmp_seq=16 ttl=64 time=102.342 ms 64 bytes from 192.168.1.3: icmp_seq=17 ttl=64 time=25.249 ms Even if this is double what the iPhone-Host or Host-iPhone time would be, 15ms+ is too long for the app I'm considering. Is there any faster way around this (e.g., USB cable)? If not, would building the app on Android offer any other options? Traceroute reports more workable times: traceroute to 192.168.1.3 (192.168.1.3), 64 hops max, 52 byte packets 1 192.168.1.3 (192.168.1.3) 4.662 ms 3.182 ms 3.034 ms can anyone decipher this difference between ping and traceroute for me, and what they might mean for an application that needs to talk to (and from) a host?

  • Why is a CoreData forceFetch required after a delete on the iPad but not the iPhone?

    - by alyoshak
    When the following code is run on the iPhone the count of fetched objects after the delete is one less than before the delete. But on the iPad the count remains the same. This inconsistency was causing a crash on the iPad because elsewhere in the code, soon after the delete, fetchedObjects is called and the calling code, trusting the count, attempts access to the just-deleted object's properties, resulting in a NSObjectInaccessibleException error (see below). A fix has been to use that commented-out call to performFetch, which when executed makes the second call to fetchObjects yield the same result as on the iPhone without it. My question is: Why is the iPad producing different results than the iPhone? This is the second of these differences that I've discovered and posted recently. -(NSError*)deleteObject:(NSManagedObject*)mo; { NSLog(@"\n\nNum objects in store before delete: %i\n\n", [[self.fetchedResultsController fetchedObjects] count]); [self.managedObjectContext deleteObject:mo]; // Save the context. NSError *error = nil; if (![self.managedObjectContext save:&error]) { } // [self.fetchedResultsController performFetch:&error]; // force a fetch NSLog(@"\n\nNum objects in store after delete (and save): %i\n\n", [[self.fetchedResultsController fetchedObjects] count]); return error; } (The full NSObjectInaccessibleException is: "Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x1dcf90 <x-coredata://DC02B10D-555A-4AB8-8BC4-F419C4982794/Blueprint/p"

  • iPhone table header lables not showing up in Release build but show up OK in Debug build

    - by Robert
    My table header shows up ok with Release build or Debug build for the iPhone simulator, but the header labels only show up with debug build on the iPhone. No header labels show up on the iPhone for release build. Any ideas? Thanks, Robert My code for the header is below - (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)sectionNum { @try { // create the parent view that will hold header Label UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(HEADER_RELX_OFFSET, HEADER_RELY_OFFSET, HEADER_ROW_WIDTH, HEADER_HEIGHT)] autorelease]; UILabel* headerLabel = [[UILabel alloc] initWithFrame:CGRectZero]; headerLabel.backgroundColor = [UIColor clearColor]; headerLabel.opaque = NO; headerLabel.numberOfLines = 0; headerLabel.textColor = [UIColor blackColor]; headerLabel.highlightedTextColor = [UIColor whiteColor]; headerLabel.font = [UIFont boldSystemFontOfSize:HEADER_FONT_SIZE]; headerLabel.textAlignment = UITextAlignmentCenter; headerLabel.lineBreakMode = UILineBreakModeWordWrap; headerLabel.frame = CGRectMake(HEADER_RELX_OFFSET, HEADER_RELY_OFFSET, HEADER_ROW_WIDTH, HEADER_HEIGHT); if(sectionNum == 0) headerLabel.text = @"My Label"; else headerLabel.text = @""; [customView addSubview:headerLabel]; return customView; @catch (NSException* exception) { NSLog(@"viewForHeaderInSection: %@: %@",[exception name],[exception reason]); } }

  • How do I secure a .NET Web Service for use by an iPhone application?

    - by David A Gibson
    Hello, The title says it all, I have a Web Service written in .NET that provides data for an iPhone application. It will also allow the application make a "reservation." Currently it's all internal to the corporate network but obviously when the iPhone application is published I will need ensure the Web Service is available externally. How would I go about securing the Web Service? There are two aspects I'm looking into: Authentication for accessing the web service Protection for the data being transferred I'm no so bothered about the data being passed back and forth as it will be viewable in the application anyway (which will be free). The key issue for me is preventing users from accessing the Web Service and making reservations themselves. At the moment I am considering encrypting any strings in the XML data passed back and forth so only the client can effectively use the web service sidestepping the need for authentication and providing protection for the data. This is the only model I have seen but I think the overheads on the iPhone and even for the web service make for a poor user experience. Any solutions at all would be most welcome? Thanks

  • What are possible/good ways to prototype iPhone applications?

    - by Ted Johnson
    This is intentionally left broad. If you wanted to show users what iPhone/mobile applications could to for them. The more interactive the better, but it must be quick to build as you can't code up every idea. Let us assume real-time games are out of scope. Throw out ideas or state which approach would be best. Here are some of my ideas, what are yours? Hack a app that loads mostly web or image content, but has hyperlinks to get around in. This would mean static data. Build screens which look great but can only be navigated in a story board type fashion. Load the web version or equivalent on the iPhone and say: now image the buttons and navigation is better. A paper based prototype. Flash or video walk through running on the phone. String existing iPhone apps and web pages together with minimal glue just to convey the idea. Can anyone share prototyping methods for other mobile devices? Ex: The palm prototype was just a block of wood and note pad that was carried around.

  • MPMoviePlayerController seems to make 2 calls for each movie

    - by user76328
    I seem to have an issue where an iphone app using the MPMoviePlayerController seems to make 2 calls to the server for each video it wants to play back. This occurs with iphone 3.x OS and libraries but not with iphone 2.x. I know that iphone does progressive download and will make multiple 206 requests, etc. but as far as our back end is concerned the player appears to make 2 separate sessions. This only appears to be an issue with iPhone native apps and not iphone videos played through safari. Additional info from apple: iPhone OS 3.0 added support for streaming audio and video over HTTP, and MPMoviePlayerController must validate the media before playback to determine if it is streaming content or progressively downloaded content. This is the delay you are experiencing. On a fast network, the delay should be minimized. Is this double check causing 2 sessions be created for each video request? Any one else seeing same issue? Is there a remedy?

  • NSString within a link

    - by MN
    Hi, I have a UIWebView that loads a link, http://www.google.com/a/datacommsales.net. But I want to have the datacommsales.net part interchangable. What I would like it to be is http://www.google.com/a/stringOne, stringOne being the NSString, so I can set the value of the string and change the link without editing the code. But the link is inside quotes, @"http://www.google.com/a/datacommsales.net", so it doesn't recognize the string. How could I include the string's value as part of the link? Any help is appreciated.

  • jQuery Mobile tap bug : same target twice

    - by hugo
    I'm working on displaying some text in an UIWebView on iOS. I'd like to get the content of the HTML element tapped by the user. If he taps on a paragraph for example, a popup shows the paragraph content. I'm using jQuery Mobile to achieve this. Here's what I'm doing : $('body').tap(function(e) { var tappedElement = $(e.target); alert(tappedElement.text()); }); It works for the first tap. The second tap no matter where it is, returns the same text. The event seems to be ok but the target property of the second tap is wrong. On the third tap all comes back to normal and so on ... What am I missing here ? thx

  • Site won't open in Facebook App for ios, nor redirect to Safari

    - by user1431811
    I'm not a heavy coder here, so i'll ask my best. We made a brochure about our home town. However users spreading it trough facebook cant open the links when in their facebook app. The app does not send it to safari either. If opened directly from safari it is no problem. The link is http://visit.lodingen360.com Is there anything i can do to the site/index.html/whatever that will make it open in safari when the link is clicked in the facebook app for ios? (that won't affect visiting the site from pc's and so on) Is there anything uiwebview won't read that can force it to safari, so that we can redirect from the thing opened in safari to the site?

  • iOS JavaScript bridge

    - by andr111
    I'm working on an app where I'm going to use both HTML5 in UIWebView and native iOS framework together. I know that I can implement communication between JavaScript and Objective-C. Are there any libraries that simplify implementing this communication? I know that there are several libraries to create native iOS apps in HTML5 and javascript (for example AppMobi, PhoneGap), but I'm not sure if there is a library to help create native iOS apps with heavy JavaScript usage. I need to: Execute JS methods from Objective-C Execute Objective-C methods from JS Listen to native JS events from Objective-C (for example DOM ready event)

  • Which is the best way to sync and share contacts and calender between Thunderbird, iPhone and Android?

    - by bensch
    I would like to keep my contacts and a calendar synchronized between several desktops and cellphones. Is there a way to achieve this without using Google or similar organisations? I want to keep my data protected and safe, so an encrypted transfer would be useful. Do i need to install a service on my own rootserver? or are there any services available, that are safe? I read this post, but there is not mentioned not to use Google: Thunderbird contacts sync so no solutions with SoGo or LDAP. maybe Zimbra is a solution? or Funambol? I tried kolab, but had some unsolveable problems.

  • OpenWorld on your iPad and iPhone

    - by KLaker
    Most of you probably know that each year I publish a data warehouse guide for OpenWorld which contains links to the latest data warehouse videos, a calendar for the most important sessions and labs and a section that provides profiles and relevant links for all the most important data warehouse presenters. For this year’s conference made all this information available in an HTML app that runs on most smartphones and tablets. The pictures below show the HTML app running on iPad and iPhone. This exciting new web app contains information about why you should attend OpenWorld - just in case you have not yet booked your ticket! - as well as the following information: Getting to know 12c - a series of video interviews with George Lumpkin, Vice President of Data Warehouse Product Management Your presenters - full biographies and links to social media sites for all the key data warehouse presenters Must sees sessions - list of all the most important data warehouse presentations at this year’s conference Our customers - profiles our most important data warehouse customers Must attend labs - list of all the most important data warehouse hands-on labs at this year’s conference Links - a list of links to the most important data warehouse sites If you want to run these web apps on your smartphone and/or tablet then follow these links: iPhone - https://876d5e65b7768ca57d1fd1236578c9374b1fca87.googledrive.com/host/0Bz-zGlWahRf4OXNzejBiRFV5ZXc/iPhone-DWoow2014.html iPad - https://876d5e65b7768ca57d1fd1236578c9374b1fca87.googledrive.com/host/0Bz-zGlWahRf4OXNzejBiRFV5ZXc/iPad-DW2014.html Android users: I have tested the app on Android and there appears to be a bug in the way the Chrome browser displays iframes because scrolling does not work . The app does work correctly if you use either the Android version of the Opera browser or the standard Samsung browser. If you have any comments about the app (content you would like to see) then please let me know. Enjoy OpenWorld.
