  • Alternatives to UIWebView for rich content?

    - by ojreadmore
    In my app, I am displaying 4 "tabs", each are local content through a UIWebView. I create HTML markup from my simple data. This is slow to load and I'm trying to speed it up. I'm using UIWebView to accomplish these: 1. hyperlinks 2. some styling - font colors 3. HTML tables Writing my own class to handle this is okay for (1.) hyperlinks - I can use a touch event to call a method. And (2.) styling - I can use UILables to do basic formatting, no biggie here. BUT what I really love about the UIWebViews is the (3.) HTML tables! I find it troublesome to line up the UILabels in a way that mimics HTML Tables, for instance, one cell's height in a row changes the height of all cells. I'm looking for another perspective or knowledge of an alternative.

    - by Code
    Hi guys, I'm trying to work out an app design in my head and I would like the user to be able to click there destination address on the map of there area.

I've never used googlemap/api yet so just wondering if this kind of thing is possible on the iphone yet. Many Thanks -Code

  • Best way to remove from NSMutableArray while iterating?

    - by Andrew Grant
    In Cocoa, if I want to loop through an NSMutableArray and remove multiple objects that fit a certain criteria, what's the best way to do this without restarting the loop each time I remove an object? Thanks, Edit: Just to clarify - I was looking for the best way, e.g. something more elegant than manually updating the index I'm at. For example in C++ I can do; iterator it = someList.begin(); while (it != someList.end()) { if (shouldRemove(it)) it = someList.erase(it); }

  • _NSAutoreleaseNoPool Breaking but No Helpful Stack Trace

    - by Matt Long
    I am getting the message: * _NSAutoreleaseNoPool(): Object 0x3f43660 of class UICFFont autoreleased with no pool in place - just leaking I have placed a break point using the symbol _NSAutoreleaseNoPool and the program does break, however, the stack trace does not show me any of my code only some UIView and Core Animation layer code. Is there a better way to get to the bottom of the issue? There is apparently a thread that does not have an auto release pool, but I can't figure out where. Thanks.

  • Pass a class as a parameter?

    - by JuBu1324
    I have been lead to believe that it is possible to pass a class as a method parameter, but I'm having trouble implementing the concept. Right now I have something like: - (id)navControllerFromView:(Class *)viewControllerClass title:(NSString *)title imageName:(NSString *)imageName { viewControllerClass *viewController = [[viewControllerClass alloc] init]; UINavigationController *thisNavController = [[UINavigationController alloc] initWithRootViewController: viewController]; thisNavController.tabBarItem = [[UITabBarItem alloc] initWithTitle: title image: [UIImage imageNamed: imageName] tag: 3]; return thisNavController; } and I call it like this: rootNavController = [ self navControllerFromView:RootViewController title:@"Contact" imageName:@"my_info.png" ]; What's wrong with this picture?

  • Is there a way to set an int to 001

    - by H.aLFaRSi
    i need to set an integer to start from 001 instead of only 1 int iNumber = 001; NSLog(@"%d",iNumber); // this is logging 1 instead of 001 is there a possible way to make it 001 ? [UPDATED] i need this because i`m creating an NSMutableArray from NSUserDefaults, after that I'm sorting the array using NSSortDescriptor. the problem is because i can't set the int to start from 001 the array i sorted like this 0, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9. More Code explained NSString *name = @"Name"; NSUserDefaults *MainArray = [NSUserDefaults standardUserDefaults]; NSString *Temp = [NSString stringWithFormat:@"%@%d", name,MainNumber]; [MainArray setObject:@"test" forKey:Temp]; [MainArray synchronize]; NSLog(@"%@",Temp); MainNumber++; the above code will save it like this : Name1,Name2,Name3.... i need it to be Name001, Name002, Name003 ....... thank you in advance :)

  • Autorelease and properties

    - by ganuke
    I have few questions to ask about the following class #import <Cocoa/Cocoa.h> @interface SomeObject { NSString *title; } @property (retain) NSString *title; @end implementation SomeObject @synthesize title; -(id)init { if (self=[super init]) { self.title=[NSString stringWithFormat:@"allyouneed"]; } return self; } -(void)testMethod{ self.title=[[NSString alloc] init] ; } -(void)dealloc { self.title=nil; [super dealloc]; } In the .h file do we need to declare the title and sub when we add the property. is it not enough to add the @property (retain) NSString *title; line. 2.Do i need to autorelease both assignment to title in the init and testMethod. if So why? Can some one explain these things to me.

  • Send copy of class to view class so it can render him? ( iPhone )

    - by Johannes Jensen
    I'm making a game for the iPhone, and I have a class called Robot. Then I have a class called View, which renders everything. I want to send a copy of my Robot, which I defined in my ViewController, and I send it to gameView (which is View *gameView), like this: robot = [Robot new]; [gameView setRobot: [robot copy]]; I tried to make a copy but that didn't work, I could also do it with a pointer to Robot (&robot) but sometimes it just crashes ? I tried this in my View.h @interface definition: @property (copy) Robot* robot; but I get the error /RobotsAdventure/Classes/View.h:24: error: setter '-robot' argument type does not match property type :/ Help? I'm pretty new at this, heh.

  • quartz2d translating the origin

    - by qwertyp96
    My understanding of quartz2d is that the code CGContextTranslateCTM(context, x, y); translates the coordinate system. I have a quartz2d view with lots of shapes on it, and the user needs to be able to pan around and zoom it. However, when using the CGContextScaleCTM(context, scaleX, scaleY); code, everything scales around the origin, not the center of the viewpoint the user is viewing. My solution to this was to use the following code: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, 512.0+offset.x, 384.0+offset.y); //(512, 384) is the center of the iPad screen CGContextScaleCTM(context, scale, scale); You can translate around fine, but things still scale into the corner. What's wrong? EDIT: Oh. Wow. Duh. If you move the origin, the shapes move too, so you can't move it relative to the shapes. Now I know what's wrong, but how do I do that?(move the origin independently of the shapes)

  • iphone getting hours/min/seconds app crashes.

    - by coure06
    i have this code in my overridden drawRect method NSDate *date = [NSDate date]; NSCalendar *calendar = [NSCalendar currentCalendar]; unsigned int unitFlags = NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit; NSDateComponents *comp = [calendar components:unitFlags fromDate:date]; NSInteger h = [comp hour]; NSInteger m = [comp minute]; NSInteger s = [comp second]; NSLog(@"%i,%i,%i", h,m,s); NSLog(@"test"); [date release]; [calendar release]; [comp release]; I am calling drawRect using setNeedsDisplay from my custom method (timer based after each 1 secon). It runs only once and then app exit automatically. If i comment out all the code and just write NSLog(@"test"); then application works ok, it logs "test" after each 1 sec.

  • Remove only first instance of a character from a list of characters

    - by Luke
    Hi All, Here's what I want to do. I have 2 strings and I want to determine if one string is a permutation of another. I was thinking to simply remove the characters from string A from string B to determine if any characters are left. If no, then it passes. However, I need to make sure that only 1 instance of each letter is removed (not all occurrences) unless there are multiple letters in the word. An example: String A: cant String B: connect Result: -o-nec- Experimenting with NSString and NSScanner has yielded no results so far.

I just tried adding self.adBannerView = nil; [adBannerView release];` just before i push the viewController but i still get that error

  • Global NSMutableArray doesn't seem to be holding values

    - by diatrevolo
    I have a Cocos2D iPhone application that requires a set of CGRects overlaid on an image to detect touches within them. "Data" below is a class that holds values parsed from an XML file. "delegateEntries" is a NSMutableArray that contains several "data" objects, pulled from another NSMutableArray called "entries" that lives in the application delegate. For some strange reason, I can get at these values without problems in the init function, but further down the class in question, I try to get at these values, and the application crashes without an error message (as an example, I put in the "ccTouchBegan" method which accessess this data through the "populateFieldsForTouchedItem" method. Can anyone see why these values would not be accessible from other methods? No objects get released until dealloc. Thanks in advance! @synthesize clicked, delegate, data, image, blurImage, normalImage, arrayOfRects, delegateEntries; - (id)initWithTexture:(CCTexture2D *)aTexture { if( (self=[super initWithTexture:aTexture] )) { arrayOfRects = [[NSMutableArray alloc] init]; delegateEntries = [[NSMutableArray alloc] init]; delegate = (InteractivePIAppDelegate *)[[UIApplication sharedApplication] delegate]; delegateEntries = [delegate entries]; data = [delegateEntries objectAtIndex:0]; NSLog(@"Assigning %@", [[delegateEntries objectAtIndex:0] backgroundImage]); NSLog(@"%@ is the string", [[data sections] objectAtIndex:0]); //CGRect rect; NSLog(@"Count of array is %i", [delegateEntries count]); //collect as many items as there are XML entries for(int i=0; i<[delegateEntries count]; i++) { if([[delegateEntries objectAtIndex:i] xPos]) { NSLog(@"Found %i items", i+1); [arrayOfRects addObject:[NSValue valueWithCGRect:CGRectMake([[[delegateEntries objectAtIndex:i] xPos] floatValue], [[[delegateEntries objectAtIndex:i] yPos] floatValue], [[[delegateEntries objectAtIndex:i] xBounds] floatValue], [[[delegateEntries objectAtIndex:i] yBounds] floatValue])]]; } else { NSLog(@"Nothing"); } } //remove the following once the NSMutableArray from above works (legacy) blurImage = [[NSString alloc] initWithString:[data backgroundBlur]]; NSLog(@"5"); normalImage = [[NSString alloc] initWithString:[data backgroundImage]]; clicked = NO; } return self; } And then: - (void)populateFieldsForTouchedItem:(TouchedRect)touchInfo { Data *touchDatum = [[Data alloc] init]; touchDatum = [[self delegateEntries] objectAtIndex:touchInfo.recordNumber]; NSLog(@"Assigning %@", [[[self delegateEntries] objectAtIndex:touchInfo.recordNumber] backgroundImage]); rect = [[arrayOfRects objectAtIndex:touchInfo.recordNumber] CGRectValue]; image = [[NSString alloc] initWithString:[[touchDatum sections] objectAtIndex:0]]; [touchDatum release]; } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { TouchedRect touchInfo = [self containsTouchLocation:touch]; NSLog(@"Information pertains to %i", touchInfo.recordNumber); if ( !touchInfo.touched && !clicked ) { //needed since the touch location changes when zoomed NSLog(@"NOPE"); return NO; } [self populateFieldsForTouchedItem:touchInfo]; NSLog(@"YEP"); return YES; }

  • How to tell a UITableView to preload all Rows?

    - by Infinite
    Is there a way to tell a UITableView to preload all rows? The tableView is supposed to show several comments (up to 80 comments). So my CommentCell uses a Setter to adapt the cell to a specific comment. -(void)setComment:(Comment *)newComment { if (newComment != comment) { [comment release]; comment = [newComment retain]; /* * set the cells view variables here */ } } This specific setter takes quite a bunch of processing resources and scrolling gets kinda laggy. I am using a comment-specific reuseIdentifier instead of a static cellIdentifier when calling dequeueReusableCellWithIdentifier: in order to assure, that "newComment" equals the old "comment". And in fact this does work great when scrolling over cells which have already been loaded. But when scrolling through the comments for the first time, it still lags like hell. Which leads me to my question: Is there a way to tell the tableview to preload all cells? (which I doubt) or Do I have to implement my own cache instead of relying on "dequeueReusableCellWithIdentifier:"?
