  • Animate screen while loading textures

    - by Omega
    My RPG-like game has random battles. When the player enters a random battle, it is necessary for my game to load the textures used within that battle (animated monsters, animations, etc). The textures are quite a lot, and rather big (the battles are very graphical intensive). Such process consumes significant time. And while it is loading, the whole screen freezes. The game's map freezes, and the wait time is significant - I personally find it annoying. I can't afford to preload the textures because, after doing some math, I realized: If I preload all the textures at the beginning of the game, the application will definitely crash. If I preload the textures that are used in a specific map when the player enters the map, the application is very likely to crash as well. I can only afford to load the textures when I need them, and dispose of them as soon as the battle ends. I'd prefer to not use a "loading screen" image because it affects my game's design and concept. I want to avoid this approach. If I could do some kind of animation while loading the textures, it would be great, which leads to my question: is that possible? What kind of animation, you ask? Well, how about... you remember when Final Fantasy used to distort the screen while apparently loading the textures? Something like that. But well, distorting is quite a time-consuming process as well, so maybe just a cool frame-by-frame animation or something. While writing this, I realized that I could make small pauses between textures (there are multiple textures), and during such pauses, I update the screen to represent the animation's state. However, this is very unlikely to happen, because each texture is 2048x2048, so the animation would be refreshed at a rather laggy (and annoying) rate. I'd prefer to avoid this as well.

  • iPhone: How do I override the back button in a Navigation Controller?

    - by Angelo Stracquatanio
    Hello, In my app I have a basic Navigation Controller. For all of my views, except one, the controller works as it should. However, for one view in particular, I would like the 'back' button to not go back to the previous view, but to go to one I set. In particular it is going to go back 2 views and skip over one. After doing some research I found that I can intercept the view when it disappears, so I tried to put in code to have it navigate to the page I would like: - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; //i set a flag to know that the back button was pressed if (viewPushed) { viewPushed = NO; } else { // Here, you know that back button was pressed mainMenu *mainViewController = [[mainMenu alloc] initWithNibName:@"mainMenu" bundle:nil]; [self.navigationController pushViewController:mainViewController animated:YES]; [mainViewController release]; } } That didn't work, so does anyone have any ideas? Thanks!!

  • Added CAGradientLayer, getting this in my UIView dealloc: [CALayer release]: message sent to deallocated instance

    - by developerdoug
    Here there, I have a custom UIView. This view acts as a activity indicator but as label above the UIActivityIndicatorView. In the init, I add a CAGradientLayer. I allocate and initialize it and insert it at index 0 as a sublayer of the UIView layer property. In my dealloc method was called, I received a message in the console: - [CALayer release]: message sent to deallocated instance. My code: @interface LabelActivityIndicatorView () { UILabel *_label; UIActivityIndicatorView *_activityIndicatorView; CAGradientLayer *_gradientLayer; } @end @implementation LabelActivityIndicatorView //dealloc - (void) dealloc { [_label release]; [_activityIndicatorView release]; //even tried to remove the layer [_gradientLayer removeFromSuperLayer]; [_gradientLayer release]; [super dealloc]; } // init - (id) initWithFrame:(CGRect)frame { if ( (self = [super initWithFrame:frame]) ) { // init the label // init the gradient layer _gradientLayer = [[CAGradientLayer alloc] init]; [_gradientLayer setBounds:[self bounds]]; [_gradientLayer setPosition:CGPointMake(frame.size.width/2, frame.size.height/2)]; [[self layer] insertSublayer:_gradientLayer atIndex:0]; [[self layer] setNeedsDisplay]; } return self; } @end Anyone have any ideas. Since I'm allocating and initializing the gradient layer I'm responsible for releasing it. I should be able to alloc and init and assign to some ivar. Perhaps I should create a property with retain on it. Thanks,

  • iOS iPad Master Detail template can't interact with detail view

    - by CraigularB
    I have an iPad app generated from the Master-Detail template in XCode. The iPad Storyboard has under the Detail View Controller a View that holds a ScrollView which holds an ImageView. In the DetailViewController.m file I added the following code to allow the ScrollView to move and zoom the image: -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return self.comicImage; } This works great on the iPhone (it's a universal app) but not the iPad; I can scroll and zoom the image on the iPhone no problem, but on the iPad it's like the ScrollView isn't responding to the touches, and I can't figure out how to pass the touches on to the ScrollView. I've already deactivated the popover controller from appearing with a right swipe like this: self.splitViewController.presentsWithGesture = NO; How do I make it so the user can interact with the ScrollView in the DetailViewController?

  • Clicking the mouse down to drag objects on Mac

    - by Uri
    I've been using the following code to issue clicks programmatically on a Mac void PostMouseEvent(CGMouseButton button, CGEventType type, const CGPoint point) { CGEventRef theEvent = CGEventCreateMouseEvent(NULL, type, point, button); CGEventSetType(theEvent, type); CGEventPost(kCGHIDEventTap, theEvent); CFRelease(theEvent); } void Click(const CGPoint point) { PostMouseEvent(kCGMouseButtonLeft, kCGEventMouseMoved, point); NSLog(@"Click!"); PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseDown, point); PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseUp, point); } Now, I'm trying to click down to be able to drag objects, like a scroll bar or an application's window. I'm using the following: PostMouseEvent(kCGMouseButtonLeft, kCGEventMouseMoved, point); NSLog(@"Click Down!"); PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseDown, point); When i ran the code above something interesting will happen, when the left mouse down is issue nothing seem to happen, I move my mouse and the window doesn't move, however when I added a mouse up event then the window jumped to the location where I supposedly dragged it. this is sort of OK, however, how do I can make the mouse click down and drag an object? Note: I do have a whole method to see when the mouse stopped moving so I can click up. please post code. Thanks

  • What is the performance difference between blocks and callbacks?

    - by Don
    One of the things that block objects, introduced in Snow Leopard, are good for is situations that would previously have been handled with callbacks. The syntax is much cleaner for passing context around. However, I haven't seen any information on the performance implications of using blocks in this manner. What, if any, performance pitfalls should I look out for when using blocks, particularly as a replacement for a C-style callback?

  • Cell Dequeue problem when table inside another table's cell content view

    - by Shailesh Kanzariya
    I am using two table views (Main Table and Sub Table), one table inside other's cell. I am adding Sub Table in Main Table's cell content view. I am also using different Cell Identifier for both table cells. Now, issue is : When - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath is called, very first time cell of Main Table is generated and when I scroll up/down they all are just dequeued, so it is expected and standard behavior and working fine. But, cell of Sub Table is getting created/allocated every time. It is not dequeued as it should be. I guess, its happening because Sub Table is part of Main Table's Cell Content view. But not sure and don't know how to resolve it. Can somebody help me to find the solution?

  • Code Interaction with Quartz Composition

    - by Alberto MQO
    Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

  • Should I merge .pbxproj files with git using merge=union?

    - by Ortwin Gentz
    I'm wondering whether the merge=union option in .gitattributes makes sense for .pbxproj files. The manpage states for this option: Run 3-way file level merge for text files, but take lines from both versions, instead of leaving conflict markers. This tends to leave the added lines in the resulting file in random order and the user should verify the result. Normally, this should be fine for the 90% case of adding files to the project. Does anybody have experience with this?

  • Cant access NString after callback in [NSURLConnection sendSynchronousRequest]

    - by John ClearZ
    Hi I am trying to get a cookie from a site which I can do no problem. The problem arises when I try and save the cookie to a NSString in a holder class or anywhere else for that matter and try and access it outside the delegate method where it is first created. - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { int i; NSString* c; NSArray* all = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[NSURL URLWithString:@"http://johncleary.net"]]; //NSLog(@"RESPONSE HEADERS: \n%@", [response allHeaderFields]); for (i=0;i<[all count];i++) { NSHTTPCookie* cc = [all objectAtIndex: i]; c = [NSString stringWithFormat: @"%@=%@", [cc name], [cc value]]; [Cookie setCookie: c]; NSLog([Cookie cookie]) // Prints the cookie fine. } [receivedData setLength:0]; } I can see and print the cookie when I am in the method but I cant when trying to access it form anywhere else even though it gets stored in the holder class @interface Cookie : NSObject { NSString* cookie; } + (NSString*) cookie; + (void) setCookie: (NSString*) cookieValue; @end int main (void) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; JCLogin* login; login = [JCLogin new]; [login DoLogin]; NSLog([Cookie cookie]); // Crashes the program [pool drain]; return 0; }

  • Is there a more efficient way to do this?

    - by garethdn
    I'm hoping there is a better way to the following. I'm creating a jigsaw-type application and this is the current code i'm using: -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; //location of current touch CGPoint location = [touch locationInView:self.view]; if ([touch view] == img1) { [self animateFirstTouch:img1 withLocation:location]; } else if ([touch view] == img2) { [self animateFirstTouch:img2 withLocation:location]; } else if ([touch view] == img3) { [self animateFirstTouch:img3 withLocation:location]; } else if ([touch view] == img4) { [self animateFirstTouch:img4 withLocation:location]; } else if { ...... ...... } else if ([touch view] == img40) { [self animateFirstTouch:img40 withLocation:location]; return; } } I'm hoping that there is a better, more efficieny way to do this, rather than naming every image. I'm thinking something like, if touch view is equal to a UIImageView, then perform some task. The same for touchesEnded: -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; //location of current touch CGPoint location = [touch locationInView:self.view]; if ([touch view] == image1) { [self animateReleaseTouch:image1 withLocation:location]; } else if ([touch view] == image2) { [self animateReleaseTouch:image2 withLocation:location]; } else if ([touch view] == image3) { [self animateReleaseTouch:image3 withLocation:location]; } else if ([touch view] == image4) { [self animateReleaseTouch:image4 withLocation:location]; } else if{ ...... ...... } else if ([touch view] == image40) { [self animateReleaseTouch:image40 withLocation:location]; } return; } Any help please?

  • NSCFType keeps occurring, something is not being released?

    - by user1493543
    I'm attempting to delete files from the documents directory using a tableview/array combination. For some reason, my NSString pointing to the Documents directory path is being converted to a NSCFType (which after some research, I understand is happening because a variable is not being released). Because of this, the application crashes at the line NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; claiming that NSCFType cannot recognize the method stringByAppendingPathComponent. I would appreciate if someone could help me out (I hope I have explained this clearly enough). - (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { NSString *temp = [directoryContent objectAtIndex:indexPath.row]; NSLog(temp); NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; [[NSFileManager defaultManager] removeItemAtPath:lastPath error:nil]; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDirectory = [paths objectAtIndex:0]; directoryContent = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil] retain]; //tableview handling below }
