  • Can I move the order of XCode, Cocoa, and User Templates around in XCode 3.1?

    - by Warren P
    I followed the other questions on StackOverflow and made custom User Templates. Instead of replacing the factory default Cocoa class template, I have to pick a new user template. The order that is shown in XCode's New File dialog box is: iPhone templates first (great if you mostly do iphone development) Second the User templates Third the default Mac OS templates. I want my user stuff first, Mac OS templates second, and I want to bury iPhone templates in third and last place. The sort is obviously not alphabetical. And you can't drag/drop reorder. (At least not in xcode 3.1.3)? From stackoverflow

  • Problem when use compiled .A with simulator mode

    - by Paska
    Hi all, i have a lib .a that run only in device mode. My sdk vers is 4.2 with xcode 3.2.x. In simulator, compile correctle with no warning and no errors, but in run mode (simulator) it crash with this error: Detected an attempt to call a symbol in system libraries that is not present on the iPhone: strtod$UNIX2003 called from function pj_init in image MyAPP. If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first Program received signal: “SIGABRT”. I try to clean, rebuild and set "set start-with-shell off" from terminal in this way: cd ~ echo '' >> .gdbinit echo 'set start-with-shell 0' >> .gdbinit Restarted all, but nothing. The problem don't wont to resolve! Is there any tag or property that i forgotted to set in the options? In other linker flag is there only "-ObjC". It's very important to solve this issue... any idea please? thanks, A EDIT: It's my lib, compiled in simulator mode! EDIT: It run only with Simulator 4.1. Don't work with iphone 4.0, 4.2 and ipad 3.2 (all simulator).

  • How to check for an active Internet Connection on iPhone SDK?

    - by Brock Woolf
    I would like to check to see if I have an Internet connection on the iPhone using the Cocoa Touch libraries. I came up with a way to do this using an NSUrl. The way I did it seems a bit unreliable (because even Google could one day be down and relying on a 3rd party seems bad) and while I could check to see for a response from some other websites if Google didn't respond, it does seem wasteful and an unnecessary overhead on my application. - (BOOL) connectedToInternet { NSString *URLString = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"]]; return ( URLString != NULL ) ? YES : NO; } Is what I have done bad? (Not to mention 'stringWithContentsOfURL' is deprecated in 3.0) And if so what is a better way to accomplish this?

  • custom UIButton with skewed area in iPhone

    - by sugar
    I want to have a button on a screen with this image. this image is transparent from its corners as you can see here. UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom]; [btn setFrame:CGRectMake(xCo, yCo, kImageSizeWidth, kImageSizeHeight)]; [btn setImage:[UIImage imageNamed:@"aboveImg.png"] forState:UIControlStateNormal]; [btn addTarget:self action:@selector(btnTapped:) forControlEvents:UIControlEventTouchDown]; But the button tap is recognized out side image & i don't want that kind of functionality. I mean tap must be recognized only when it is tapped within image not outside image. How is that possible ? Thanks in advance for sharing your great knowledge. Sagar.

  • Resizing UIView to match its content

    - by Thody
    I have a UITextField, a UIButton, and a UIWebView nested in a UIView, which is nested in a UIScrollView. After the UIWebView has loaded its content, I need it to resize the UIWebView and UIView so that the UIScrollView will scroll. I currently have the UIScrollView getting its contentSize from the UIView, but I can't figure out how to do the resizing after the UIWebView's content has loaded.

  • iPhone YouTube Channel App

    - by pki
    What would the steps be to creating an app that connected to YouTube's XML API. Here is my setup currently but it is not working. App Delegate creates object "YTXMLParser" App Delegate calls [parser prepAndPrase]; In Prep and Parse the app initiates a NSURLConnection The app downloads the XML Data using the NSURLConnection well appeneding to NSMutableData The app parses the data with NSXMLParser At the end of each "entry" the app adds the current dictionary to the class. At the beginning of each "entry" the app creates an instance of a dictionary. Here's where i'm stuck. How do I get this data back to my app delegate?

  • How to rotate a UIImageView?

    - by jkally
    It's quite frustrating not to be able to do such a simple task: I have an "app" with a single viewcontroller, and in it a single UIImageView, that's initialized to a specific image at potrtait mode. Now when the iPhone gets roteated to landscape mode and the shouldAutorotateToInterfaceOrientation event fires, at which I return YES, my resulting UIImageView looks totally screwed up: either the image is stretched so to fill landscape mode frame (which looks ridiculuous of course) or the top and bottom of the image are cropped. How can I have my UIImageview and the contained image handle the device rotation gracefully, and display normal looking image at landscape mode as well?

  • Manipulating a NSTextField via AppleScript

    - by Garry
    A little side project I'm working on is a digital life assistant, much like project JARVIS. What I'm trying to do is speak to my mac, have my words translated to text and then have the text interpreted by my program. Currently, my app is very simple, consisting of a single window containing a single wrapped NSTextView. Using MacSpeech Dictate, When I say the custom command "Jeeves", MacSpeech ensures that my app is frontmost, highlights any text in the TextField and clears it, then presses the Return key to trigger the textDidEndEditing method of NSTextField. This is done via Applescript. MacSpeech then switches to dictation mode and the next sentence I say will appear in the NSTextField. What I can't figure out is how to signify that I have finished saying a command to my program. I could simply say another keyword like "execute" or something similar that would send an AppleScript return keystroke to my app (thereby triggering the textDidEndEditing event) but this is cumbersome. Is there a notification that happens when text is pasted into a NSTextField? Would a timer work that would fire after maybe three seconds once my program becomes frontmost (three seconds should be sufficient for me to say a command)? Thanks,

  • iOS - Application logging test and production code

    - by Peter Warbo
    I am doing a bunch of logging when I'm testing my application which is useful for getting information about variable state and such. However I have read that you should use logging sparsely in production code (because it can potentially slow down your application). But my question is now: if my app is in production and people are using it, whenever a crash (god forbid) occurs, how will I be able to interpret the crash information if I have removed the logging statements? Then I suppose I will only have a stacktrace for me to interpret? Does this mean I should leave logging in production code only WHERE it's really essential for me to interpret what has happened? Also how will the logging statements relate to the crash reports? Will they be combined? I'm thinking of using Flurry as analytics and crash reports...

  • Could InAppSettingsKit do this, or is there another library?

    - by cannyboy
    I'm trying to implement a system whereby the user is initially presented with a single tablecell, in a uitableview (grouped style), within a uinavigationview. --------------- + | add record | --------------- When they click on the cell, they are pushed onto a new screen where they fill in a few textviews (perhaps imbedded in a tableview's cells) --------------- | (name) | --------------- | (phone num) | --------------- Then when they go back, they can see the new record as well as the 'add record' cell. --------------- | record 1 | --------------- + | add record | --------------- (When they go into record 1 again there would be a delete button) Is there any sample code or libraries which would achieve this? What about InAppSettingsKit? It's more the presentation I'm concerned with. I can handle the saving of data myself.

  • Getting a UIImage from MySQL using PHP and jSON

    - by Daniel
    I'm developing a little news reader that retrieves the info from a website by doing a POST request to a URL. The response is a jSON object with the unread-news. E.g. the last news on the App has a timeStamp of "2013-03-01". When the user refreshes the table, it POSTS "domain.com/api/api.php?newer-than=2013-03-01". The api.php script goes to the MySQL database and fetches all the news posted after 2013-03-01 and prints them json_encoded. This is // do something to get the data in an array echo $array_of_fetched_data; for example the response would be [{"title": "new app is coming to the market", "text": "lorem ipsum dolor sit amet...", image: XXX}] the App then gets the response and parses it, obtaining an NSDictionary and adds it to a Core Data db. NSDictionary* obtainedNews = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error]; My question is: How can I add an image to the MySQL database, store it, pass it using jSON trough a POST HTTP Request and then interpret it as an UIImage. It's clear that to store an UIImage in CoreData, they must be transform into/from NSData. How can I pass the NSData back and forth to a MySQL db using php and jSON? How should I upload the image to the db? (Serialized, as a BLOB, etc)

  • AVAudioPlayer lag when calling play

    - by joec
    I have set up an AVAudioPlayer object in viewDidLoad, as per the Apple guidelines, calling prepareToPlay as the last line in viewDidLoad (i have tried in awakeFromNib also). When i press my play button, there is a pause, as it would appear to load the file, then it plays. In audioPlayerDidFinishPlaying, i reload the player with a different sound, and when clicking play for a second time, the file plays instantly. What would cause the player to lag on the first play? Thanks.

  • Optimizing tiled maps in cocos2d-iphone

    - by Omega
    My cocos2d-iphone game has tiled maps. The tilesets textures are rather big. I got around 5 tilesets and each one is 2048x2048 (retina). My maps are around 80x80. They have around 8 layers and each one is obviously using one tileset. The frame rate falls (it goes around 30 sometimes. I know 30 is rather aceptable, but still, I want 50+). So given that textures are huge I can't afford to make many layers (since each one loads a texture of these). So how about I divide my tileset textures into much smaller tilesets (like 1024x1024 each)? That will allow me to use many more layers for my maps, right? Are there any other tips for huge retina display tile maps?

  • Init array with bool values

    - by iFloh
    my attempt to init an array with a number of bool values using: [myArray initWithObjects:[NSNumber numberWithBool:YES], [NSNumber numberWithBool:YES], [NSNumber numberWithBool:YES], nil]; seems to fail since the debugger shows an empty array after this statement is carried out ... Any clues?

  • The item you tried to buy is no longer available [Environment: Sandbox]

    - by Ansari
    I am trying to put In App purchase in my application. I had setup a consumable product which was working fine in Sandbox environment. Now i just made a new product which is non-consumable with new price tier, and deleted the old one. Update my code, with the new Product ID. When request is sent, it properly shows the right Product with newly added price tier, But when you tap on Buy button it gives you the error "The item you tried to buy is no longer available [Environment: Sandbox]". Any idea ?
