  • UIWebView - remote html loading local images

    - by AragornSG
    I'm trying to develop an application using UIWebView. The app is loading remote URL's, so in order to make it quick I want it to use the images included in the application bundle. I was wondering if there is a way to do it without forcing the application to manually replace the address of each image to point into local resources?

  • Knowing which annotation is selected and accessing properties of it.

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • How to quickly access documentation in Xcode 4.5.1?

    - by International Frog
    How can I quickly access the documentation for a symbol, method, enum, etc. in Xcode 4.5? alt + click on symbol shows a quick-info. Apple removed the dictionary icon which opened the documentation. I tried all other possible shortcuts of the cmd / alt / shift / click mumbo jumbo dance and none of them open the documentation browser. I suppose there is a hidden trick to quickly open it anyways? Edit: Figured out this new quick-info box has a link to the documentation.

  • Transfer Core Data from One Project to Another

    - by Michael
    The answer is probably a resounding 'NO' but before I start a new project from scratch, I thought I'd ask. I create many throw away projects to test ideas and code before combining all the successful bits from the scratch projects into a final version. So I have one project with the Core Data stuff worked out but I want to move it to a new project. My guess is that there is too many internal hooks and dropping in the .xcdatamodel and the sqlite db is just not going to work. I'd glad to be wrong...

  • Static Analyzer says I have a leak....why?

    - by Walter
    I think this code should be fine but Static Analyzer doesn't like it. I can't figure out why and was hoping that someone could help me understand. The code works fine, the analyzer result just bugs me. Coin *tempCoin = [[Coin alloc] initalize]; self.myCoin = tempCoin; [tempCoin release]; Coin is a generic NSObject and it has an initalize method. myCoin is a property of the current view and is of type Coin. I assume it is telling me I am leaking tempCoin. In my view's .h I have set myCoin as a property with nonatomic,retain. I've tried to autorelease the code as well as this normal release but Static Analyzer continues to say: 1. Method returns an Objective-C object with a +1 retain count (owning reference) 2. Object allocated on line 97 is no longer referenced after this point and has a retain count of +1 (object leaked) Line 97 is the first line that I show.

  • Trick to getting initWithNibFile to be invoked?

    - by PhazeZero
    I've implemented a View Controller, and I'm trying to do some very basic initialization in initWithNibFile...which I understand to be the designated initializer for View Controller objects. I've tried to put breakpoints on the code, and have put very simple NSLog statements into it as well. Regardless...I'm not seeing it be executed (and the object i'm attempting to alloc/init inside the function is also not being allocated - so I'm about 99% sure I'm not hitting the code. Is there something I need to do elsewhere to cause this method to be invoked? I'm getting a clean build, no warnings or errors. And the app successfully loads up the View, and I can invoke a ButtonClick method I've coded and connected to this same View Controller. Any suggestions would be appreciated. TC

  • UITableViewCell and strange behaviour in grouped UITableView

    - by evangelion2100
    I'm working on a grouped UITableView, with 4 sections with one row per section, and have a strange behaviour with the cells. The cells are plain UITableViewCells, but the height of the cells are around 60 - 80 pixel. Now the tableview renders the cells correct with round corners, but when I select the cells, they appear blue and recangle. I don't know why the cells behave like this, because I have another grouped UITableView with custom cells and 88 pixel height and those cells work like they should. If I change the height to the default height of 44 pixel, the cells behave like the should. Does anyone know about this behaviour and what the cause is? Like I mentioned, I don't do any fancy stuff I use default UITableViewCells in a static, grouped UITableView with 4 sections with 1 row in each section. evangelion2100

  • Are @property's necessary for Interface Builder?

    - by Rits
    In my UIViewController subclass, I have 3 UIView's with each a @property as an IBOutlet. I do not use these properties at all in my code. The views get instantiated as soon as the view controller is created and they are deallocated when the view controller is deallocated. I was thinking; can't I just remove the @property's? I did, and I could still connect my instance variables (with IBOutlet) in Interface Builder. So my question now is; is there any use for properties in combination with Interface Builder, or is it OK to leave them out? Is it required for some memory management or something? Or are they really just for use in your own code? And if I do leave them out, do I still need to release them in dealloc?

  • Textures loaded with NSOperation are blank

    - by Omega
    So I call this method: -(void)beginExecution { NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(execute) object:nil]; [queue addOperation:operation]; [operation release]; } Which triggers this: -(void)execute { [[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:@"MyTexture.plist"]; loaded = YES; // This tells me whenever loading is done. } However, when I create a sprite and try to use the texture MyTexture.png, the sprite is a blank canvas. Why is that?

  • iOS Question. Is There a Framework for Build Time Based Apps.

    - by dugla
    I have the need for some time based effects in the iPad app I am building. The UIView class animation capability beginAnimatins/commitAnimations is exactly the sort of thing I am looking for but it is restricted to specific properties of UIView deemed animatable. Ideally, I am looking for a solution that lets me drive an a time-based function that can perhaps send messages to a class of my own choosing at the rate I specify in the animation. Specifically, I have a function - my implementation of the RenderMan function "smoothstep" which is essentially an ease-in ease-out curve common in animation. It takes [0 - 1] as input and outputs [0 - 1] as the curve is evaluated. I want to drive this function for a duration of my own choosing at rate of my own choosing. Thanks in advance. -Doug

  • How does Core Data determine if an NSObjects data can be dropped?

    - by Kevin
    In the app I am working on now I was storing about 500 images in Core Data. I have since pulled those images out and store them in the file system now, but in the process I found that the app would crash on the device if I had an array of 500 objects with image data in them. An array with 500 object ids with the image data in those objects worked fine. The 500 objects without the image data also worked fine. I found that I got the best performance with both an array of object ids and image data stored on the filesystem instead of in core data. The conclusion I came to was that if I had an object in an array that told Core Data I was "using" that object and Core Data would hold on to the data. Is this correct?

  • Images appear in simulator but not when uploading to ipod touch (3.0)

    - by user139190
    I created a simple test app with an image (as well as a button with an image) and it runs fine in the simulator. But when uploading to the iPod, none of the images appear. The button appears but with no image. A few things worth mentioning: - Today's massive achievement was making it beyond the code signing errors and so I have not had any applications uploaded to the device until now. IOW, it's not a sudden change. - The png image is about 100 x 200. - I also set an icon image (png 24 x 24) that does not appear either. Thanks in advance for any advice.
