  • How can I tell the size of my app during development?

    - by Newbyman
    My programming decissions are directly related to how much room I have left, or worse perhaps how much I need to shave off in order to get up the 10mb limit. I have read that Apple has quietly increased the 3G & Edge download limit from 10mb up to 20mb in preparation for the iPad in April. Either way, my real question is how can I gauge a rough estimate of how large my app will end while I'm still in the development phase? Is the file size of my development folder roughly 1 to 1 ratio? Is the compressed file size of my development a better approximation? My .xcodeproj file is only a couple hundred kB, but the size of my folder is 11.8 MB. I have a .sqlite database, less than 20 small png images and a Settings.Bundle. The rest are unknown Xcode files related to build, build for iphoneOS, simulator etc.... My source code is rather large with around 1000 lines in most of the major controllers, all in all around 48 .h&.m files. But my classes folder inside my development folder is less than 800kb. Digging around inside my Build file, there is lots of iphone simulator files and debugging files which I don't think will contribute to the final product. The Application file states that it is around 2.3 MB. However, this is such a large difference from the 11.8 MB, I have to wonder if this is just another piece of the equation. I have the app on the my device, I'm in the testing phase. Therefore, I though that I would try to see how large the working version was on the device by checking in iTunes, however my development app is visible on the right-hand the application's iphone screen, but no information about the app most importantly its size. I also checked in Organizer, I used the lower portion of the screen-(Applications), found my application and selected the drop down arrow which gave my "Application Data" and a download arrow button to the right to save a file on my desktop, named with the unique AppleID. Inside the folder it had three folders-(documents, library, tmp) the documents had a copy of my .sqlite database, the library a few more files but not anything obvious or of size, and the tmp was empty. All in all the entire folder was only 164kb-which tells me that this is not the right place to find the size either. I understand that the size is considered to be the size of my binary plus all the additional files and images that I have add. Does anyone have a effective way of guaging how large the binary is or the relating the development folder size to what the final App Store application size will end up. I know that questions have been posted with similar aspects, but I could not find any answered post that really described...what files, or how to determine size specifically. I know that this question looks like a book, but I just wanted to be specific in conveying exactly what I'm looking for and the attempts thus far. *Note all files are unzipped and still in regular working Xcode order of a single app with no brought-in builds or referenced projects. I'm sure that this is straight forward, I just don't know where to look?

  • Font size render in iphone

    - by Terix
    Hi everybody, i'm testing my website and is waorking fine on every browser, except for the iphone browser (i think it's safari mobile?) that renders a piece of text with a bigger font that the rest. I've checked the CSS by hands and using firebug on the page and i can confirm i've put the same size to all of them. How do i fix this? You can check the site on www.ilsegnale.it/?tpl=502 The piece of text i'm talking about it the one under "approfondimento" box

  • iPhone apps for company-internal use - possible?

    - by Michael Stum
    I hope this is still programming related, as SuperUser doesn't seem the appropriate place. Basically I wonder if it is possible to have Applications that are internal to a company on the iPhone? That is something like a companion Application to an Intranet (when Safari and Mail just don't cut it) which wouldn't make sense on the AppStore (and likely wouldn't get approved anyway). Is something like that possible (without Jailbreaking or doing anything else that Apple doesn't normally want)?

  • HTML5 Offline Storage on iPad and iPhone BUG

    - by scaraveos
    Hello everyone, I created a manifest file with 1000 items. Safari, Mozilla browsers are saving the files offline successfully and even Android saves the files correctly offline. On iPad and iPhone when I am trying to save more than 300 items in some point the applicationCache returns "error". When I am trying to save less (e.x.: 200) it saves the files correctly and the applicationCache returns "cached". Any ideas? Thank you.

  • Develop an iPhone / iPad Reader app from scratch

    - by Comma
    I'm developing a reader app for viewing and highlighting proprietary format documents. The documents are 2D. (Might add some cool page flip effects) The interface is similar to that of mobile safari. I have no prior experience with iOS development. Could you guys point me to the right direction?

  • Google CDN - using http vs https

    - by HorusKol
    All the examples of accessing google's CDN use https:// in the URL (including on Google itself) - but this has caused a problem when testing in Safari (certificate problem and also different domain). <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> I have switched to calling it over http instead, but just wondering if this is a mistake or security issue?

  • optimizing iPhone OpenGL ES fill rate

    - by NateS
    I have an Open GL ES game on the iPhone. My framerate is pretty sucky, ~20fps. Using the Xcode OpenGL ES performance tool on an iPhone 3G, it shows: Renderer Utilization: 95% to 99% Tiler Utilization: ~27% I am drawing a lot of pretty large images with a lot of blending. If I reduce the number of images drawn, framerates go from ~20 to ~40, though the performance tool results stay about the same (renderer still maxed). I think I'm being limited by the fill rate of the iPhone 3G, but I'm not sure. My questions are: How can I determine with more granularity where the bottleneck is? That is my biggest problem, I just don't know what is taking all the time. If it is fillrate, is there anything I do to improve it besides just drawing less? I am using texture atlases. I have tried to minimize image binds, though it isn't always possible (drawing order, not everything fits on one 1024x1024 texture, etc). Every frame I do 10 image binds. This seem pretty reasonable, but I could be mistaken. I'm using vertex arrays and glDrawArrays. I don't really have a lot of geometry. I can try to be more precise if needed. Each image is 2 triangles and I try to batch things were possible, though often (maybe half the time) images are drawn with individual glDrawArrays calls. Besides the images, I have ~60 triangles worth of geometry being rendered in ~6 glDrawArrays calls. I often glTranslate before calling glDrawArrays. Would it improve the framerate to switch to VBOs? I don't think it is a huge amount of geometry, but maybe it is faster for other reasons? Are there certain things to watch out for that could reduce performance? Eg, should I avoid glTranslate, glColor4g, etc? I'm using glScissor in a 3 places per frame. Each use consists of 2 glScissor calls, one to set it up, and one to reset it to what it was. I don't know if there is much of a performance impact here. If I used PVRTC would it be able to render faster? Currently all my images are GL_RGBA. I don't have memory issues. Here is a rough idea of what I'm drawing, in this order: 1) Switch to perspective matrix. 2) Draw a full screen background image 3) Draw a full screen image with translucency (this one has a scrolling texture). 4) Draw a few sprites. 5) Switch to ortho matrix. 6) Draw a few sprites. 7) Switch to perspective matrix. 8) Draw sprites and some other textured geometry. 9) Switch to ortho matrix. 10) Draw a few sprites (eg, game HUD). Steps 1-6 draw a bunch of background stuff. 8 draws most of the game content. 10 draws the HUD. As you can see, there are many layers, some of them full screen and some of the sprites are pretty large (1/4 of the screen). The layers use translucency, so I have to draw them in back-to-front order. This is further complicated by needing to draw various layers in ortho and others in perspective. I will gladly provide additional information if reqested. Thanks in advance for any performance tips or general advice on my problem!

  • iPhone Crash Report

    - by skywalker168
    My iPhone app is crashing for certain users in UK. I tried using UK timezone and their region format but couldn't reproduce the crash on my iPhone or emulator. Eventually got a crash report and I was able to symbolicate it. However, I have a hard time understanding the results. It appears thread 0 crashed in a system library. The only call from my app is main.m. Thread 4 has something familiar. It was at: My App 0x00004cca -[TocTableController parser:didEndElement:namespaceURI:qualifiedName:] (TocTableController.m:1369) Code is: NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; It crashed doing alloc/init? Out of memory, only in UK? Any one has idea what might be cause? Thanks in advance!

  • Xcode/iPhone Development 6 months in - Annoyances

    - by clearbrian
    Hi I've been iPhone programming for 6 months and come from a PC/Java/Eclipse background and still have a few annoyances with Xcode/iPhone programming I wonder are there any shortcuts to. Is there any way to prevent multiple windows opening all the time in XCode? a) When you click on the Errors/Warnings in the bottom right of the status bar build errors are shown in separate window. Any way to get these to show in the main editor? b) Anyway to get debugger to appear in main editor. I have a big screen iMac and it's still window hell on Macs. When you come from Alt-Tab the Mac is a nightmare. 2) Anyway to get a toolbar item on the main editor to: a) Open Console (I know CMD-thingy-R) b) Open Break points (you have to open Debugger first then breakpoints) I know there's keyboard shortcuts but I have only left hand free others on the trackball so any keys on right hand side of keyboard are too far. I know you can add Finder toolbar scripts (just wondering if anyway to extend Xcode). Are there utilities to extend Xcode? Scripts/Automator/Any Services I can setup to help. Can you automate Xcode like you can with Windows/ActiveX/VBA 3) Limit lookups using CMD + double click. If I double click on a variable to find its definition using CMD + double click it shows every occurrence of all variables with that name. (annoying it you name all you maps mapView) Anyway to get it to limit to the current class or at least order so current class is first. 4) Find doesn't seem to loop backwards if result all above cursor position I'm in a class and I hit CMD + F for find. Find box appears. I enter some text hit return. It says I have x matches but only back arrow is highlight in Find But when I hit < it does nothing. I need to scroll to the top and redo the search. If the text is both forwards and backwards then both < are highlighted and it works. is this a bug or a 'feature' Missing Eclipse features I have been looking at the User Script menu but was wondering how powerful they are? 5) any scripts around to generate source from members such as description: @property @synthesize if I add a new member, run a script will generate @property/@syntesize and release in dealloc 7) any good sites for scripts? SCM Im having problems with SCM and Folders on HD under project Classes directory. You get a library e.g. JSON. It usually comes as a folder. You copy it to the /Classes for your project. /Classes/JSON I create a Group for the Library in Xcode under Classes group. Classes JSON I drag the files from the folder into xcode into the JSON Group. I add them to the SCM and icon changes from ? to A but if I try and commit them it say folder /JSON is not under SCM. Can you drag a folder into Xcode so that it AND its files get included in SCM? Anyway to stop Xcode Help from being on top all the time. I keep feeling like punching it and telling it to get out of the way! :) I dont mind it open just not in the way once I've finished. Yes I know I can Ctrl-W Sites: the main site I use to learn Obj-C are : stackoverflow.com Google code Search - tonnes of full apps on here http://www.iphonedevsdk.com/forum/iphone-sdk-development/ Apple Developers Forums (anyway to get RSS feed to these or is that blasphemy :) ) Safari - 100s of IT book though prob too many to keep up :) any others? Any site that gives simple examples for Obj-C/ UIKit The docs just show the methods but actual examples (Google code search has helped a lot here)

  • zLib on iPhone, stop at first BLOCK

    - by cedric
    I am trying to call iPhone zLib to decompress the zlib stream from our HTTP based server, but the code always stop after finishing the first zlib block. Obviously, iPhone SDK is using the standard open Zlib. My doubt is that the parameter for inflateInit2 is not appropriate here. I spent lots of time reading the zlib manual, but it isn't that helpful. Here is the details, your help is appreciated. (1) the HTTP request: NSURL *url = [NSURL URLWithString:@"http://192.168.0.98:82/WIC?query=getcontacts&PIN=12345678&compression=Y"]; (2) The data I get from server is something like this (if decompressed). The stream was compressed by C# zlib class DeflateStream: $REC_TYPE=SYS Status=OK Message=OK SetID= IsLast=Y StartIndex=0 LastIndex=6 EOR ...... $REC_TYPE=CONTACTSDISTLIST ID=2 Name=CTU+L%2EA%2E OnCallEnabled=Y OnCallMinUsers=1 OnCallEditRight= OnCallEditDLRight=D Fields= CL= OnCallStatus= EOR (3) However, I will only get the first Block. The code for decompression on iPhone (copied from a code piece from somewhere here) is as follow. The loop between Line 23~38 always break the second time execution. + (NSData *) uncompress: (NSData*) data { 1 if ([data length] == 0) return nil; 2 NSInteger length = [data length]; 3 unsigned full_length = length; 4 unsigned half_length =length/ 2; 5 NSMutableData *decompressed = [NSMutableData dataWithLength: 5*full_length + half_length]; 6 BOOL done = NO; 7 int status; 8 z_stream strm; 9 length=length-4; 10 void* bytes= malloc(length); 11 NSRange range; 12 range.location=4; 13 range.length=length; 14 [data getBytes: bytes range: range]; 15 strm.next_in = bytes; 16 strm.avail_in = length; 17 strm.total_out = 0; 18 strm.zalloc = Z_NULL; 19 strm.zfree = Z_NULL; 20 strm.data_type= Z_BINARY; 21 // if (inflateInit(&strm) != Z_OK) return nil; 22 if (inflateInit2(&strm, (-15)) != Z_OK) return nil; //It won't work if change -15 to positive numbers. 23 while (!done) 24 { 25 // Make sure we have enough room and reset the lengths. 26 if (strm.total_out >= [decompressed length]) 27 [decompressed increaseLengthBy: half_length]; 28 strm.next_out = [decompressed mutableBytes] + strm.total_out; 29 strm.avail_out = [decompressed length] - strm.total_out; 30 31 // Inflate another chunk. 32 status = inflate (&strm, Z_SYNC_FLUSH); //Z_SYNC_FLUSH-->Z_BLOCK, won't work either 33 if (status == Z_STREAM_END){ 34 35 done = YES; 36 } 37 else if (status != Z_OK) break; 38 } 39 if (inflateEnd (&strm) != Z_OK) return nil; 40 // Set real length. 41 if (done) 42 { 43 [decompressed setLength: strm.total_out]; 44 return [NSData dataWithData: decompressed]; 45 } 46 else return nil; 47 }

  • Dashcode code translation

    - by Alex Mcp
    Hi, a quick, probably easy question whose answer is probably "best practice" I'm following a tutorial for a custom-template mobile Safari webapp, and to change views around this code is used: function btnSave_ClickHandler(event) { var views = document.getElementById('stackLayout'); var front = document.getElementById('mainScreen'); if (views && views.object && front) { views.object.setCurrentView(front, true); } } My question is just about the if conditional statement. What is this triplet saying, and why do each of those things need to be verified before the view can be changed? Does views.object just test to see if the views variable responds to the object method? Why is this important? EDIT - This is/was the main point of this question, and it regards not Javascript as a language and how if loops work, but rather WHY these 3 things specifically need to be checked: Under what scenarios might views and front not exist? I don't typically write my code so redundantly. If the name of my MySQL table isn't changing, I'll just say UPDATE 'mytable' WHERE... instead of the much more verbose (and in my view, redundant) $mytable = "TheSQLTableName"; if ($mytable == an actual table && $mytable exists && entries can be updated){ UPDATE $mytable; } Whereas if the table's name (or in the JS example, the view's names) ARE NOT "hard coded" but are instead a user input or otherwise mutable, I might right my code as the DashCode example has it. So tell me, can these values "go wrong" anyhow? Thanks!

  • iPad and UIPickerView (or UIDatePickerView)

    - by Staros
    Hey all, Has anyone had any luck using a UIPicker in the 3.2 SDK? I'm in the middle of porting an iPhone application over to an iPad and that's the one thing I can't seem to get to work. I've tried... -Creating an action sheet, add the picker as a subview and displaying it. -Creating that above action sheet, making it the view of a generic ViewController, adding that VC to a UIPopover -Making just the picker the view of a generic ViewController, adding that VC to a UIPopover With the action sheet it doesn't even attempt to draw it. In the popover view it attempts to draw but doesn't get rendered correctly. Just wanted to check to see if anyone has accomplished this and if so how. Thanks everyone!

  • Framework not found CoreServices

    - by Matthew Brindley
    I'm trying to use CoreServices on the iPhone simulator (I don't need it to run on a device), but my project won't build because of the error: ld: framework not found CoreServices Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 I've added the framework to my project, under frameworks. I also read you need to include CFNetwork.framework, so I've added that too. If I remove CoreServices.framework, the compiler complains about undeclared symbols, as you'd expect. So it seems to use the framework to compile those classes, but then complains it can't find the framework.

  • Best Practices for persisting iPod Playlist (MPMediaItemCollection) across sessions

    - by coneybeare
    When using in-app audio in the iPhone SDK, it is possible to allow users to select a list from their ipod library and create an in-app local playlist. If I want to persist this choice, it is easy to serialize the data and write to file, then recover. Just vanilla like this, however, leads me to think there is going to be something wrong. For example, what if the user syncs and removes sounds? I can loop across them all and query the iPod DB at setup time, but with lists that could be 50,000 long, this could take some time. How are other people doing this and what are some gotchas that I haven't though about?

  • Set the Image brightness and contrast using OpenGL ES.

    - by Viral
    hi friends, I want to set Image Brightness and contras of images that are in my photo library, I got the code from http://developer.apple.com/iphone/library/samplecode/GLImageProcessing/Introduction/Intro.html, but that will work on the EAGL layer i.e. all the effects are provided on image that is put initially not on the image that are selected from the photo library ,as this function will work on the view(EAGLview) and not on the image view. so how to change the brightness and contras of any images that are selected from the photo library?? if any one know this please let me know.. regards viral.

  • MFMailComposeViewController: how to get notified when view appears?

    - by Karsten Silz
    In my app, users can take a picture with the camera or pick one from the library and email it as an attachment. I use the MFMailComposeViewController for seamless email. On my iPhone 3GS, it takes about 5-7 seconds for the email view to appear with the attachment. Now I want to show a progress indicator view when the user pushes the "Send" button and hide that view when the email view comes up. The problem is that the MFMailComposeViewController delegate only calls when the email sending is done. Can I get notified somehow when the email window appears on the screen?

  • Toggle Wifi On/Off using MobileWifi private framework

    - by Ben Williams
    Hello, For a private project using the iPhone SDK (not for the app store), I would like to toggle wifi on & off. I've done something similar for Bluetooth, but can't find the required information for Wifi. I assume I need to use the MobileWifi framework. Can anyone give some directions and/or code? Most likely I expect I need a header file for the MobileWifi framework as well. Note once again, this is not for the app store, as Apple will not allow apps that use private frameworks such as this.

  • Pushing a ABUnknownPersonViewController onto a navigation controller results in having no Navigation

    - by dermdaly
    Hi There, I'm working with the Address Book UI API on iPhone SDK 3.0. I want to present to the user the ability to create a new user, or add to an existing one, so I am using the ABUnknownPersonViewController. I have an existing navigation stack (with only 2 other views on it). Trouble is when I push the ABUnknownPersonViewController onto it, it shows up animated, etc. But there is no navigation bar, so no way to cancel. My code snippet is as follows newPersonViewController = [[ABUnknownPersonViewController alloc] init]; newPersonViewController.unknownPersonViewDelegate = self; newPersonViewController.displayedPerson = person; newPersonViewController.allowsAddingToAddressBook = YES; newPersonViewController.allowsActions = NO; [[self navigationController] pushViewController:newPersonViewController animated:YES]; Note: the current view controller does have a title, so that's not the issue. Any ideas what I am missing?
