• Problem with pre-beta sdk - even after reinstalling SDK 3.2

  - by Anders Brenna

  I'm trying to upload the binary for a new app, but always get this errormessage: "The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application." I know several people have asked a similar question, but I've tried all suggestions from the answers there without success. I used the XCode 4.0 beta 3 during development, and I've tried using it to compile for earlier releases (3.0, 3.1.3, 3.2 etc...) I've also tried downgrading to SDK 3.2, as well as removing 4.0 beta 3 and then installing SDK 3.2 as a fresh install. It seems to me that there might be some parameter in the "Edit Project Settings" that is sticking from the use of 4.0 beta 3, but I've tried to identify them without success. My last option seem to be a complete reinstall of both OS and SDK. Is there something else I might try first?

• iPhone SDK 3.2 beta and iPhone SDK 3.1.2

  - by pratik

  Hello, Currently I am using iPhone SDK 3.1.2 for developing iPhone apps. Apple has recently released iPhone SDK 3.2 beta and I want to try my hands with it. But my problem is that I want to use both versions of SDKs, 3.1.2 since I am currently developing apps and uploading on app store, 3.2 beta to start trying the new version (but Apple will not accept apps on App Store, if developed using 3.2 beta) Please guide me. Regards, Pratik

• iphone - How do I add videos to iPad simulator?

  - by Mike

  No, dropping the videos to ~/Library/Application Support/iPhone Simulator/3.2/Media/DCIM/100APPLE does not work totally, because the simulator can see the video on Photos.app, but when I try to pick a video using UIImagePickerController my application crashes. I think this may have some relation to the format the video has to have. I am using QuickTime to generate the video. I am using the settings "for iPhone"... so it is generating a M4V with 480x360 pixels H264. I have tried to create a MOV with the same characteristics and one with 640x480 but nothing works. I have also dropped a movie created with iPhone 3GS and it still crashes. this is the error I see when it crashes * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)' the method didFinishPickingMediaWithInfo is never called, so its some issue on the simulator or on the video. The app crashes as soon as I pick the video. any ideas? thanks.

• Gizmodo Made No Money On Their iPhone 4G Scoop Blog Posts

  - by Gopinath

  Amit Agarwal of Labnol reported couple of days ago that Gizmodo would have made $150,000 from the iPhone 4G scoop that revealed  all the secrets about iPhone 4G. But the reality seems to be entirely different. Gawker Media owner Nick Denton says that "There were no immediate revenue benefits whatsoever — in fact, only costs,"(via businessinsider) Gizmodo paid $5,000 to get hold of iPhone 4G which was lost by an Apple Engineer at a bar after his birthday party. Plus an additional amount of $7000 is spent on keeping the servers up to server 23 page views attracted by the iPhone 4G blog posts. Irrespective of whether Gizmodo made profits or not, they got huge publicity. But at the same time Apple should be very angry with Gizmodo for derailing it’s planned unveiling of the product. We have to wait and see what action Apple is going to take against Gizmodo. Join us on Facebook to read all our stories right inside your Facebook news feed.

• Looking For iPhone 4S Alternatives? Here Are 3 Smartphones You Should Consider

  - by Gopinath

  If you going to buy iPhone 4S on a two year contract in USA, Europe or Australia you may not find it expensive. But if you are planning to buy it in any other parts of the world, you will definitely feel the heat of ridiculous iPhone 4S price. In India iPhone 4S costs approximately costs $1000 which is 30% more than the price tag of an unlocked iPhone sold in USA. Personally I love iPhones as there is no match for the user experience provided by Apple as well as the wide range of really meaning applications available for iPhone. But it breaks heart to spend $1000 for a phone and I’m forced to look at alternates available in the market. Here are the four iPhone 4S alternates available in almost all the countries where we can buy iPhone 4S Google Galaxy Nexus The Galaxy Nexus is Google’s own Android smartphone manufactured by Samsung and sold under the brand name of Google Nexus. Galaxy Nexus is the pure Android phone available in the market without any bloat software or custom user interfaces like other Androids available in the market. Galaxy Nexus is also the first Android phone to be shipped with the latest version of Android OS, Ice Cream Sandwich. This phone is the benchmark for the rest of Android phones that are going to enter the market soon. In the words of Google this smartphone is called as “Galaxy Nexus: Simple. Beautiful. Beyond Smart.”.  BGR review summarizes the phone as This is almost comical at this point, but the Samsung Galaxy Nexus is my favourite Android device in the world. Easily replacing the HTC Rezound, the Motorola DROID RAZR, and Samsung Galaxy S II, the Galaxy Nexus champions in a brand new version of Android that pushes itself further than almost any other mobile OS in the industry. Samsung Galaxy S II The one single company that is able to sell more smartphones than Apple is Samsung. Samsung recently displaced Apple from the top smartphone seller spot and occupied it with loads of pride. Samsung’s Galaxy S II fits as one the best alternatives to Apple’s iPhone 4S with it’s beautiful design and remarkable performance. Engadget summarizes Samsung Galaxy S2 review as It’s the best Android smartphone yet, but more importantly, it might well be the best smartphone, period. Of course, a 4.3-inch screen size won’t suit everyone, no matter how stupendously thin the device that carries it may be, and we also can’t say for sure that the Galaxy S II would justify a long-term iOS user foresaking his investment into one ecosystem and making the leap to another. Nonetheless, if you’re asking us what smartphone to buy today, unconstrained by such externalities, the Galaxy S II would be the clear choice. Sometimes it’s just as simple as that. Nokia Lumia 800 Here comes unexpected Windows Phone in to the boxing ring. May be they are not as great as Androids available in the market today, but they are picking up very quickly. Especially the Nokia Lumia 800 seems to be first ever Windows Phone 7 aimed at competing serious with Androids and iPhones available in the market. There are reports that Nokia Lumia 800 is outselling all Androids in UK and few high profile tech blogs are calling it as the king of Windows Phone. Considering this phone while evaluating the alternative of iPhone 4S will not disappoint you. We assure. Droid RAZR Remember the Motorola Driod that swept entire Android market share couple of years ago? The first two version of Motorola Droids were the best in the market and they out performed almost every other Android phone those days. The invasion of Samsung Androids, Motorola lost it charm. With the recent release of Droid RAZR, Motorola seems to be in the right direction to reclaiming the prestige. Droid RAZR is the thinnest smartphone available in the market and it’s beauty is not just skin deep. Here is a review of the phone from Engadget blog the RAZR’s beauty is not only skin deep. The LTE radio, 1.2GHz dual-core processor and 1GB of RAM make sure this sleek number is ready to run with the big boys. It kept pace with, and in some cases clearly outclassed its high-end competition. Despite its deficiencies in the display department and underwhelming battery life, the RAZR looks to be a perfectly viable alternative when considering the similarly-pricey Rezound and Galaxy Nexus Further Reading So we have seen the four alternates of iPhone 4S available in the market and I personally love to buy a Samsung smartphone if I’m don’t have money to afford an iPhone 4S. If you are interested in deep diving into the alternates, here few links that help you do more research Apple iPhone 4S vs. Samsung Galaxy Nexus vs. Motorola Droid RAZR: How Their Specs Compare by Huffington Post Nokia Lumia 800 vs. iPhone 4S vs. Nexus Galaxy: Spec Smackdown by PC World Browser Speed Test: Nokia Lumia 800 vs. iPhone 4S vs. Samsung Galaxy S II – by Gizmodo iPhone 4S vs Samsung Galaxy S II by pocket lint Apple iPhone 4S vs. Samsung Galaxy S II by techie buzz This article titled,Looking For iPhone 4S Alternatives?

• Corona SDK (Lua) vs Native Obj-C for iPhone only word puzzle type game [closed]

  - by dodgy_coder

  I am trying to decide on whether to use the Corona SDK & Lua versus native Objective-C to develop an iOS app. This will be the first game on any smartphone I have developed and so its not that ambitious - a single player word puzzle type game - something sort of like scrabble. The advantages of Corona I can see are: Lua is probably easier to learn than Obj-C (shorter learning curve) meaning a possibly quicker development time Possibility to port to Android once its finished Advantages of native Obj-C are: Access to all and latest features of iOS More / faster available libraries Has anyone made this decision before? Are there any major advantages or disadvantages I've missed or got wrong here? Thanks.

• ipad video format

  - by Mike

  When you use iTunes to sync your videos with the iPhone the videos are always saved with no more than 640 pixels wide, if I am not wrong. What about the iPad? What is the size of videos iTunes syncs with iPad? 1024x768? and what if the video has a dimension below 1024x768? Will it scale up? or will it keep the video at low res and scale when you play? thanks.

• iPhone: Software Development And Distribution

  - by xsl

  I have a few quick questions about the iPhone software development. I did some research about the topic, but there are a few specific things I would like to ask here, because I will have to estimate the cost of the required hardware and software, before I am allowed to buy anything. I never did any Mac development nor have I ever owned an iPhone, so needless to say this is quite hard for me. I will buy an iMac mini with 2 GB RAM for iPhone development. I will have to use it at the same time as my regular PC, but the majority of the time I won't use the Mac at all. Do I have to buy an additional monitor, a mouse and a keyboard or is there a better solution? I will have to port a C library to the iPhone platform and develop an iPhone application that uses the ported library. Do I need anything else than the iPhone SDK to do this? If I use an external library (see above), can I test the application with the integrated emulator, or is it recommend to buy the device? In a later phase of the project I will have to buy an iPhone, but I will have to wait until the iPhone 4 is released here in Europe, because the application requires a camera. In addition to this I will have to send data to a remote webservice. Aside from these two things I don't require any other features. Can I just buy the iPhone online from another country (the iPhones here are sim locked), or should I buy one with a contract? When the application is ready, it will be installed on a few iPhones owned by our customer. Because of security reasons it is crucial that there is no third party involved in this process (i.e. the application should not be distributed on the app store). Is this possible?

• Corona SDK: Animation takes a long time to play after "prepare" step

  - by Michael Taufen

  First off, I'm using the current publicly available build, version 2011.704 I'm building a platformer, and have a character that runs along and jumps when the screen is tapped. While jumping, the animation code has him assume a svelte jumping pose, and upon the detection of a collision with the ground, he returns to running. All of this happens. The problem is that there is this strange gap of time, about 1/2 a second by the feel of it, where my character sits on the first frame of the run animation after landing, before it actually starts playing. This leads me to believe that the problem is somewhere between the "prepare" step of loading up a sprite set's animation sequence and the "play" step. Thanks in advance for any help :). My code for when my character lands is as follows: local function collisionHandler ( event ) if (event.object1.myName == "character") and (event.object2.type == "terrain") then inAir = false characterInstance:prepare( "run" ) -- TODO: time between prepare and play is curiously long... characterInstance:play() end end

• iPhone - How do you make a resizable rectangle for cropping images?

  - by 0SX

  Hi everyone, I'm having a trouble making a re-sizable rectangle for cropping my images. I'm trying to achieve something like this picture: http://img192.imageshack.us/img192/8930/customcropbox.jpg Well, the only problem is I have no clue where to actually start. I need some advice to how I can achieve this effect of cropping. What documentation should I read up on? Core Graphics or Quartz 2d? Both? I've been coding for the iPhone since it's release date but I've never actually used core graphics and etc. Any help or advice would be much appreciated. I'll throw my code up here as I progress to show how it's done when I achieve it. :-) Also, this rectangular box is moveable across the screen in a UIImageView which just makes it more interesting. Thanks for the help and I look forward to achieving this goal.

• Which iPhone/iPod Hardware to Support for iPhone Game

  - by ashes999

  I'm coming from a background of Android. I would like to figure out what kind of iBlah device hardware I need to support for iPhone game development. From my research, it seems that I need to support both iPod and iPhone. But which versions of hardware? is 3G still used? What about 3GS? For example, the -S phones seem to have dual core instead of single-core CPUs. I also worry about performance. In Android, I had a severely low-end phone, which meant pretty much anything that ran okay there ran okay on other phones. For iPhone, how do I figure out what to support in terms of performance?

• How to check for server side update in iPhone application Web service request

  - by Nirmal

  Hello All.... I have kind of Listing application for iPhone application, which always calling a web service to my php server and fetching the data and displaying it onto iPhone screen. Now, the thing to consider in this scenario is, my iPhone application everytime requesting on the server and fetching the data. But now my requirement is like I want to replace following set of actions with above one : - Everytime when my application is launched in iPhone, it should check for the new data at the server`. - And if server replies "true" then only my iPhone application will made a request to fetch the data. - In case of "false", my iPhone application will display the data which is already cached in local phone memory. Now to implement this scenario at server side (which has php, mysql), I am planning with the following solution : Table : tblNewerData id newDataFlag == ============ 1 true Trigger : tgrUpdateNewData Above trigger will update the tblNewerData - newDataFlag field on Insert case of my main table. And every time my iPhone app will request for tblNewerData-newDataFlag field, and if it found true then only it will create new request, and if it founds false then the cached version of data will be displayed. So, I want to know that, is it the correct way to do so ? or else any other smart option available ? Thanks in advance.

• iPhone image asset recommended resolution/dpi/format

  - by Matthew

  I'm learning iPhone development and a friend will be doing the graphics/animation. I'll be using cocos2d most likely (if that matters). My friend wants to get started on the graphics, and I don't know what image resolution or dpi or formats are recommended. This probably depends on if something is a background vs. a small character. Also, I know I read something about using @2x in image file names to support high res iphone screens. Does cocos2d prefer a different way? Or is this not something to worry about at this point? What should I know before they start working on the graphics?

• iPhone SDK 3/4 App will not run on a iPhone 2.x device even with deployment target set to 2.0!

  - by MarqueIV

  Ok... I know about the difference between the base/active SDKs and the deployment target. I have my base SDK set at 4.0 and the deployment target set at 2.0. I am not using any APIs post 2.x, conditional or otherwise. Since I can't debug on a 2.x device, after building it, I use the iPhone Configuration Utility to install the app on the device, which it does just fine. Problem is, it doesn't run! I just get a blank screen. The main window never comes up! Now before you ask... I had this same problem with the iPhone SDK 3.x. I upgraded to the 4.x hoping it would be solved. It wasn't. Yes the provisioning profile is installed. (Couldn't install the app if it wasn't.) This same compiled app works fine on 3.x devices. Same with 4.x devices. Just not 2.x devices. Again, no I am not using any post-2.x SDKs. To prove this I created a brand-new, window-based app from the 'New Project' dialog and the only changes I made was the background color of the window (to prove the XIB loaded) and I set the deployment target to 2.0 (It's still compiled against the 4.x SDK though.) Again, it runs fine on 3.x or 4.x devices, but just a black, blank screen on 2.x devices. I've tried this on three separate 2.x devices included one freshly restored. I've used three separate dev machines (MacBook Pro with the 3.x SDK, MacBook Pro with the 4.x SDK and a Mac Pro with the 3.x SDK.) Same result every time. I am stumped. The fact that even an unmodified project doesn't run really has me confused. Could it be the XIB file? Did they change the format from 2.x to something newer in the 3.x SDK? If so, how do I set it back to 2.x. (Again, this is just a complete guess.) But I'm really stumped! Mark

• Tips on implementing a custom UITextView interface on the iPhone?

  - by Alex

  I am trying to implement a control to edit text that will display the text in multiple colors. None of the solutions I have attempted yet have been good enough. UITextView cannot accomplish this. All of the text must be the same color. Using CoreGraphics to draw the text does not allow the text to be selected. Using a UIWebView, DIV and PRE tags cannot be set to contentEditable on Mobile Safari. Currently playing with using an off-screen TEXTAREA and an on-screen DIV to show the rendered text. This works pretty well, except supporting all of these at the same time seems impossible: click-to-type, click-to-move-cursor, click-and-hold-select/copy/paste. Anyone have any tips on this predicament? I've been trying to find any preexisting library out there that will accomplish this in a good way, to no luck. I'm open to any ideas!

• Playing online video on iphone web, the iphone seems to cache the reference movie

  - by Mad Oxyn

  We are working on an online mobile video app, and are trying to play a reference movie on an iphone from the iphone browser. The problem is, the movie plays the first time, but when we try to play a different movie the second time, it doesnt. Quicktime gives a general error message sayin "Cannot Play Movie". More precisely this is what we are trying to do: Connect with an iPhone to a webserver that serves a reference movie (generated with quicktime pro). The ref movie automatically gets downloaded to the iphone by quicktime. Quicktime then chooses one of the 3 references in the reference movie, based on the connection speed, and tries to download the designated movie via a relative path. A servlet gets called and forwards the relative path to the right movie. This all works the first time. However the second time when we want download different movies, we get the quicktime error. Test case: Open reference movie 1 Movie plays in Quicktime Open reference movie 2 ERROR: Quicktime gives an error - Cannot Play Movie Shut down Iphone Turn Iphone on again Open reference movie 2 Iphone plays movie Open movie ERROR: Quicktime gives an error - Cannot Play Movie Did anyone encounter similar issues with quicktime and the use of reference movies and is there something we can do to work around that?

• Is it possible to download and run IPhone apps on an IPhone emulator

  - by Adrian Grigore

  Hi, I am tasked to provide an IPhone client app for our SaaS website. I have never written an IPhone application, nor do I have an IPhone at the moment. Before I can decide whether or not I want to do this myself or outsource this, I'd like to try a few apps myself to get a feeling for the UI. Is there any IPhone emulator I might use to download and run apps from the App Store? I do have an Intel-based Mac if that helps.
