  • Retaining objects in game iphone

    - by Brodie4598
    Hello - I am trying to create a game and have run into what is probably a pretty easy problem to solve. As the player goes through the game, many objects (Vehicle) will be added and removed. The Vehicles get added to an array called currentVehiclesMutableArray. My problem is I cant figure out how to retain a Vehicle so that it remains in the array until I am finished with it.

  • iPhone/iPad fatal error in C++ code produces no output in the log

    - by morgancodes
    I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

    - by Comma
    I'm developing a reader app for viewing and highlighting proprietary format documents. The documents are 2D.

(Things I need to consider, tutorials, sample projects...) THX

  • Wildcard App IDs for iPhone/iPod Touch Apps

    - by Can Berk Güder
    I'm writing my third app, and I already have an app in the App Store, but I still don't get this App ID business. I created the App IDs for my first two applications like this: XXXXXXXXXX.me.cbg.FirstApp YYYYYYYYYY.me.cbg.SecondApp but then Apple introduced the App ID wizard, which I used to create the App ID and provisioning profiles for my third application: ZZZZZZZZZZ.* So my question is: What is the "proper" way of creating App IDs for three completely independent apps? Should I use the XXXXXXXXXX.* format or XXXXXXXXXX.me.cbg.*? Should I create three different App IDs, or just one wildcard ID?

  • iPhone: Get value in multi-dimentional array

    - by Nic Hubbard
    I have an array that is many levels deep and I am wondering what is the best way to get one of the child element values that is deep in my array. I assume I need to use a recursive method, but what is the best way to do this? Or is there a faster way to do this? The array comes from an XML Parser that I am using which builds everything into an array like this (using NSLog to show the structure): { children = ( { children = ( { children = ( { children = ( ); data = 12; element = AssetID; } ); data = ""; element = "ns1:GetUserIdByUsernameResponse"; } ); data = ""; element = "SOAP-ENV:Body"; } ); data = ""; element = "SOAP-ENV:Envelope"; } What I would like to get at is the AssetID data, which in this case is 12.

  • Kepping object in memory (iPhone SDK)

    - by Chris
    I am trying to create a UIImageView called theImageView in the touchesBegan method that I can then then move to a new location in touchesMoved. Currently I am receiving an "undeclared" error in touchesMoved where I set the new location for theImageView. What can I do to keep theImageView in memory between these two methods? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { ... UIImageView *theImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; theImageView.frame = CGRectMake(263, 228, 193, 300); [theImageView retain]; ... } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { ... theImageView.frame = CGRectMake(300, 300, 193, 300); ... }

  • iPhone: InterfaceBuilder nibs disconnected from my project

    - by John Leonard
    Since upgrading to XCode 3.2, InterfaceBuilder doesn't play nice. All of my image links are broken in IB but they'll show fine when I compile. When I go to the combo box to select an image for my UIImageView, it doesn't have the image files I've added to my app. I also can't create a new .nib and associate it with a class I've written. Like images, my custom viewcontrollers aren't available to pick from. I'm going to try a reinstall but I was curious if anyone's dealt with this?

  • Xcode: iPhone screenshots no longer work

    - by Chris Newman
    I can't be sure when this stopped working because I haven't used it for a while, but it was possibly since I upgraded to the 3.2 SDK. In Organizer, when I select the "Screenshots" tab and press "Capture", nothing happens. I've tried this with three different devices and I've restarted my Mac. What's happened, and how can I fix it?

  • iPhone time comparison

    - by Rob
    I am trying to figure out how to create an 'if' statement that uses a time value as a condition. For example: if (time <= 10:00) { score = 3; } else if (time <= 20:00) { score = 5; } else { score = 9; } I know that a string of "5:23" cannot be compared this way but I don't think I can just turn a string value like that directly into an integer. Any thoughts?

  • Language restrictions on iPhone lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • iPhone animation with stretchable image

    - by ryyst
    I got a UIView subclass that draws a UIImage as its background. The image is created using the stretchableImageWithLeftCapWidth:topCapHeight: method, it has round edges. I also use an animation block inside of which I resize my view. I had hoped that during animation, the drawRect:method would get called sometimes, which would result in the background image getting drawn correctly. Unfortunately, the animation seems to render the image and then just rescale it during the animation, which obviously makes the formerly round edges getting nastily stretched. The only workaround I can imagine is put three separate UIImageViews (top cap, middle fill, bottom cap) above my original background image and then reposition the caps images and scaling the fill image. However, this seems quite complicated... Is there any better way I can prevent this from happening?

  • iphone shake error

    - by aaa
    Right now I have this- [code] - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (event.type == UIEventSubtypeMotionShake) { int text = rand() % 12; switch (text) { case 0: textview.text = @"blah." ; break;[/code] For some reason, the text has to be selected for it to work. If you just shake it, nothing will happen.

  • iphone best practice, how to load multiple high quality images

    - by bennythemink
    Hi guys and girls, I have about 20-ish high quality images (~3840x5800 px) that I need to load in a simple gallery type app. The user clicks a button and the next image is loaded into the UIImageView. I currently use [UIImage imageWithContentsOfFile:] which takes about 6 seconds to load each image in the simulator :( if I use [UIImage imageNamed:] it takes even longer to load but caches the images which means its quicker if the user wishes to see the same images again. But it may cause memory problems later with all that caching crashing my app. I want to know whats the best practice for loading these? I'm experimenting with reducing image file size as much as is possible but I really need them to be high quality image for the purpose of the app (zoomable, etc.). Thanks for any advice

  • iPhone producing strange results on 'if' statement

    - by Rob
    I have a UIPicker where the user inputs a specified time (i.e. 13:00, 13:01, 13:02, etc.) - which determines their score. Once they hit the button an alert comes up with the score that is determined through this 'if-else' statement. Everything seems to work great MOST of the time - but I am getting some erratic behavior. This is the code: //Gets my value from the UIPicker and then converts it into a format that can be used in the 'if' statement. NSInteger runRow = [runTimePicker selectedRowInComponent:2]; NSString *runSelected = [runTimePickerData objectAtIndex:runRow]; NSString *runSelectedFixed = [runSelected stringByReplacingOccurrencesOfString:@":" withString:@"."]; //The actual 'if' statment. if ([runSelectedFixed floatValue] <= 13.00) { runScore = 100; } else if ([runSelectedFixed floatValue] <= 13.06) { runScore = 99; } else if ([runSelectedFixed floatValue] <= 13.12) { runScore = 97; } else if ([runSelectedFixed floatValue] <= 13.18) { runScore = 96; } else if ([runSelectedFixed floatValue] <= 13.24) { runScore = 94; } else if ([runSelectedFixed floatValue] <= 13.30) { runScore = 93; } else if ([runSelectedFixed floatValue] <= 13.36) { runScore = 92; } else if ([runSelectedFixed floatValue] <= 13.42) { runScore = 90; } else if ([runSelectedFixed floatValue] <= 13.48) { runScore = 89; } else if ([runSelectedFixed floatValue] <= 13.54) { runScore = 88; } Now, when I test the program, I will get the expected result when I choose '13:00' which is '100'. I also get the expected result of '99' when I choose all of the times between '13:01 and 13:05'. BUT, when I choose '13:06' it gives me a score of '97'. I also get a score of '97' on '13:07 through 13:12' - which is the desired result. Why would I get a '97' right on '13:12' but not get a '99' right on '13:06'???? Could this be a memory leak or something???

  • Specify build folder for iphone application

    - by Martin KS
    I've written an app that uses some of the user's camera roll images, and while it does so it stores them in the application root directory. The problem I have is that whenever I re-compile my application it changes the folder to which the application is installed. Is there any way I can specify which folder it should build to, so that any path information stored during it's last run will still be valid?
