• CGContextDrawImage returning bad access

  - by Marcelo

  Hello guys, I've been trying to blend two UIImage for about 2 days now and I've been getting some BAD_ACCESS errors. First of all, I have two images that have the same orientation, basically I'm using the CoreGraphics to do the blending. One curious detail, everytime I modify the code, the first time I compile and run it on device, I get to do everything I want without any sort of trouble. Once I restart the application, I get error and the program shuts down. Can anyone give me a light? I tried accessing the baseImage sizes dynamically, but it gives me bad access too. Here's a snippet of how I'm doing the blending. UIGraphicsBeginImageContext(CGSizeMake(320, 480)); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, 0, 480); CGContextScaleCTM(context, 1.0, -1.0); CGContextDrawImage(context, rect, [baseImage CGImage]); CGContextSetBlendMode(context, kCGBlendModeOverlay); CGContextDrawImage(context, rect, [tmpImage CGImage]); [transformationView setImage:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext();

• Scale an image every time it collide with another

  - by jean mayot

  here is my code : -(void)collision{ if(CGRectIntersectsRect(imageView.frame,centre.frame)){ imageView.alpha=0; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0f]; centre.transform=CGAffineTransformMakeScale(1.3, 1.3); [UIView commitAnimations]; } } When imageView collide with centre centre become bigger. my problem is that when "imageView" collide with "centre" a second time the animation doesn't work. I want to make centre bigger and bigger and bigger every time imageView collide with center, but it become bigger just one time . Sorry for my english I'm french :/ How can I solve this please ?

  I have an xml of the following format - <plist version="1.0"> <array> <dict>...</dict> <dict>...</dict> </array> </plist> I am trying to write it into a plist using - NSDictionary *temp = [NSPropertyListSerialization propertyListWithData:returnData options:NSPropertyListImmutable format:&format error:&errorDesc]; [self writeToPlistFile:@"myList.plist" : temp]; where the method is -(BOOL)writeToPlistFile:(NSString*)filename:(NSDictionary*)data{ NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString * documentsDirectory = [paths objectAtIndex:0]; NSString * path = [documentsDirectory stringByAppendingPathComponent:filename]; BOOL didWriteSuccessfull = [data writeToFile:path atomically:YES]; return didWriteSuccessfull; } I then want to read it and place it into a dictionary.

• How to calculate the height of the text rectangle from an NSString?

  - by mystify

  I know there is this one: sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode: But since the CGSize always has the same height and doesn't adjust to any shrinked text or whatsoever, the CGSize is not telling how heigh the text is. Example: Make a UILabel with 320 x 55 points and put a loooooooooooooong text in there. Let the label shrink the text down. Surprise: CGSize.height remains the same height even if the text is so tiny that you need a microscope. Ok so after banging my head against my macbook pro which is half way broken now, the only think that can help is that nasty actualFontSize. But the font size is in pica I think, it's not really what you get on the screen, isn't it? When that font size is 10, is my text really 10 points heigh at maximum? Once in a while I tried exactly that, and as soon as the text had a y or some character that extends to below (like that tail of an y does), it is out of bounds and the whole text is bigger than 10 points. So how would you calculate the real text height for a single line uilabel without getting a long beard and some hospital experience?

• UITableView cell animate background

  - by psychotik

  I have a UITableView with a bunch of rows. When some action occurs, I want to animate the background of a cell. I just want to make it grey and then fade it back to the default in .5 seconds. Is my only option to set the background and call [tableView beginUpdates] followed by [tableView endUpdates] and then set a timer to clear the background again, or is there some more fundamental animation technique I can use here?

• Pinterest Gridview implementation on iOS

  - by Amal

  I want to implement a grid view like the one in Pinterest I thought about implementing as 3 table views. But I was not able to scroll them together well. When I implemented the scrollViewDidScroll and set the contentOffset for the table views other the scrollView , the scrolling became slow and unusable. Another implementation I did was of was having a set of images to load and calling the viewDraw function in scrollViewDidScroll. THe ViewDraw function just draws the necessary images and removes the rest of the images from the memory which were already drawn but wont be visible . this too makes the ScrollView Scrolling slow. And another issue with it is that there are white(background color) patches before the images are drawn. What should be the best way to implement this grid view ?

• UIImageView is resizing

  - by dawatson833

  I have an issue with uiimageviews resizing at run time. On one view I have more than a dozen uiimageviews contained within a uiscrollview. The images are assigned at design time. The uiimageview's are all the same size. The mode is set to Aspect Fill for all uiimageviews. At run time the images appear correctly in the view. On a second view I have only 9 uiimageviews. These uiimageviews will display up to nine of the images selected from the first view. There are three images across and three images down. The uiimageview at design time is the same size as on the first view. The uiimageview image is assigned an image that is loaded into an array. All the uiimageviews are sized the same and they also have the mode set to Aspect Fill. The images are assigned at run time using image1.image = xxx. Where xxx is an image stored in an array. However, on this second view, the images are not all the same size. The height of the image changes dynamically. The same image displayed in a different uiimageview on the view will be different sizes. It is the height of the uiimageview that changes. In some cases the image will fill the uiimageview differently. It is like the mode changes dynamically. I've tried using different modes and nothing changes. Any ideas on what is happening?

• Core Data and Relationships

  - by alku83

  I have two objects, a Trip and a Place. A Trip represents a journey from one Place to another Place, ie. a Trip needs a fromPlace and a toPlace. So, this is a 1-to-2 relationship, but I need to know which is the "from" and which is the "to". I am not sure how to model this in Core Data. I have created two entities (Trip, Place), and now I want to setup the relationship(s) so I have a fromPlace and a toPlace. Do I need to add an extra field on the Place entity called isFrom, or similar? If this was in a database, I would just have a id column on the Place table, and then two columns in the Trip table - fromPlaceId and toPlaceId. How do I achieve something similar in Core Data?

• xPath Groupings how?

  - by David

  OK So, I'm learning/using xpath for a basic application thats effectively ripping data off another website. I need to gain the knowledge of each persons Countryy/Suburb/area. In some instances you can get Australia/Victoria/melborne for instance. Others may just be Australia/Melbourne. Or even just Melbourne OR just AUSTRALIA. who knows. So I'm current able to view the below code and rip all of the information with the string xpath search:@" //table/tr/td/tabke/tr/td/font/a, this returns every entry, but what I really want is to group each lot separately. I hope someone out there on planet earth knows what I just tried to explain... and can help... Good day! <font face="arial" size="2"> <strong>Location:</strong> <a href="http://maps.google.com/maps?q=Australia" target="mapblast" style="text-decoration:none">Australia</a>, <a href='http://maps.google.com/maps?q=Australia%20Victoria'target="mapblast" style='text-decoration:none'>Victoria</a>, <a href='http://maps.google.com/maps?q=Australia%20Melbourne%20Victoria'target="mapblast" style='text-decoration:none'>Melbourne</a> </font> </td> </tr>

• Public class: The best way to store and access NSMutableDictionary?

  - by meridimus

  I have a class to help me store persistent data across sessions. The problem is I want to store a running sample of the property list or "plist" file in an NSMutableArray throughout the instance of the Persistance class so I can read and edit the values and write them back when I need to. The problem is, as the methods are publicly defined I cannot seem to access the declared NSMutableDictionary without errors. The particular error I get on compilation is: warning: 'Persistence' may not respond to '+saveData' So it kind of renders my entire process unusable until I work out this problem. Here is my full persistence class (please note, it's unfinished so it's just to show this problem): Persistence.h #import <UIKit/UIKit.h> #define kSaveFilename @"saveData.plist" @interface Persistence : NSObject { NSMutableDictionary *saveData; } @property (nonatomic, retain) NSMutableDictionary *saveData; + (NSString *)dataFilePath; + (NSDictionary *)getSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level; + (void)writeSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level withData:(NSDictionary *)saveData; + (NSString *)makeCampaign:(NSUInteger)campaign andLevelKey:(NSUInteger)level; @end Persistence.m #import "Persistence.h" @implementation Persistence @synthesize saveData; + (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kSaveFilename]; } + (NSDictionary *)getSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level { NSString *filePath = [self dataFilePath]; if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSLog(@"File found"); [[self saveData] setDictionary:[[NSDictionary alloc] initWithContentsOfFile:filePath]]; // This is where the warning "warning: 'Persistence' may not respond to '+saveData'" occurs NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *campaignAndLevelData = [[self saveData] objectForKey:campaignAndLevelKey]; return campaignAndLevelData; } else { return nil; } } + (void)writeSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level withData:(NSDictionary *)saveData { NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *saveDataWithKey = [[NSDictionary alloc] initWithObjectsAndKeys:saveData, campaignAndLevelKey, nil]; //[campaignAndLevelKey release]; [saveDataWithKey writeToFile:[self dataFilePath] atomically:YES]; } + (NSString *)makeCampaign:(NSUInteger)campaign andLevelKey:(NSUInteger)level { return [[NSString stringWithFormat:@"%d - ", campaign+1] stringByAppendingString:[NSString stringWithFormat:@"%d", level+1]]; } @end I call this class like any other, by including the header file in my desired location: @import "Persistence.h" Then I call the function itself like so: NSDictionary *tempSaveData = [[NSDictionary alloc] [Persistence getSaveWithCampaign:currentCampaign andLevel:currentLevel]];

• Drawing an image is completely out

  - by ct2k7

  Hi I'm using this code below to let a user "draw" their signature on a UIView component on my app: UIGraphicsBeginImageContext(signature.frame.size); [drawImage.image drawInRect:CGRectMake(0, 0, signature.frame.size.width, signature.frame.size.height)]; CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound); CGContextSetLineWidth(UIGraphicsGetCurrentContext(), 5.0); CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), 1.0, 0.0, 0.0, 1.0); CGContextMoveToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextAddLineToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextStrokePath(UIGraphicsGetCurrentContext()); CGContextFlush(UIGraphicsGetCurrentContext()); drawImage.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext() The issue I am having is that the drawing is not only is the drawing not in line with the pointer when in use in the simulator, the image is going outside of the designated UIView compontent and is getting smaller/out of focus the more I draw, as you can see in this image: And after a few lines, showing the boundaries of the exact are of where I can draw: Any ideas on what's happening here? lastPoint.y is defined as: lastPoint.y -= 20; Any ideas on what on earth is happening here?

• Simple ViewController / View, remove white bar?

  - by fuzzygoat

  I am just looking at setting up a simple viewController programatically, I have a ViewController.xib file that I have set the background color to RED in interface builder. I have also added the following to my AppDelegate.m @implementation syntax_MapViewAppDelegate @synthesize window; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { viewController = [[MapViewController alloc] init]; [window addSubview:[viewController view]]; [window makeKeyAndVisible]; return YES; } -(void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end When I run the code it does what I expect apart from the white bar at the bottom of the screen, can anyone give me any pointers in how to remove this? I have a feeling I might need to position the view within the window, but I am not sure how? cheers Gary

• How to extract delegates from ViewController class?

  - by adranle

  Hi I have the problem that my view controller class has too many delegates and starts to get big. I want to write the delegates in separate classes to keep the view controller class small. For delegates that are programmatically created (like UIAlertViewDelegate) I could do it easily. The problem is in the delegates assigned in Interface Builder. How can I tell the IB to assign, for example, another class as the UITableViewDelegate or UITableViewDataSource? Or how to choose another IBAction method for a Touch UP inside Event on a button? One solution would be to delete the connections from IB and write them programmatically at ViewDidLoad, but since I have a lot of ViewControllers, this would take a long time. any other ideas?
