  • How to persist and load an object which conforms to NSCoding protocol?

    - by mystify
    I have made an class which conforms to the NSCoding protocol and does all the encode and decode stuff. For my app, I simply want to persist an object from that class to the device and the next time when the app launches, I want to load that object back into memory. Basically it's just an class which holds some user input information. For example the user starts writing a text but then quits the app. Next time I want to load that data object. I guess I need NSKeyedArchiver? Is there a good tutorial on this? How do I do that?

  • Regular Expression doesn't match

    - by dododedodonl
    Hi All, I've got a regular expression in my cocoa-touch app (using RegexKitLite). NSString *week = [[NSString alloc] initWithFormat:@"%@", [pageContent stringByReplacingOccurrencesOfRegex:@"<select name=\"week\" class=\"selectbox\" style='width:134' onChange=\"doDisplayTimetable(NavBar, topDir);\">(.+?)<option value=\"(.+?)\">(.+?)</option>" withString:@"$2"]]; I expect it to match with the section of this (what is in NSString pageContent): <span class="selection"> <nobr> Periode<br> <span class="absatz"> &nbsp;<br> </span> <select name="week" class="selectbox" style='width:134' onChange="doDisplayTimetable(NavBar, topDir);"> <option value="14">17-5 - 16-7</option> </select> </nobr> </span> But it doesn't... I need the value of the option, it is possible that there is more than one (in that case I need them both separated by a ,. Can someone help me out? Regards, Dodo

  • iOS6: do we have to set rootViewController in App delegate in order to support different orientations?

    - by Centurion
    The app was perfectly fine working in iOS5 in landscape orientation. However in iOS6, it started to use portrait orientation in all view controllers. The methods shouldAutorotateToInterfaceOrientation are not called anymore. I read the new stuff about changed rotation mechanism in iOS6 and I was able to fix that by adding a line in my AppDelegate: self.window.rootViewController = _viewController _viewControler is the starting screen (Home-menu). All other view controllers implement shouldAutorotateToInterfaceOrientation method and returns YES for landscape orientations only. So, it's perfectly working solution for the app that needs to support only one orientation. However, the problem is I need one view controller (lets call it phone-VC) to be presented in portrait orientation. Now, if I want this view controller would be rotated then I need to return YES in Home-menu controller that is assigned to rootViewControler in appDelegate. However, I can't do that because this rootViewController is starting window that need to presented in landscape only, otherwise the layout with graphics in this window will break. But if I don't return YES from its shouldAutorotateToInterfaceOrientation (Home-menu) then the same method is not called in my view phone-VC that needs to be presented in portrait. Any ideas? Does the assignation of rootViewController is mandatory in AppDelegate? UPDATE: the problem exists on device (at least on iPhone4).

  • Best practise - Accessing preferences globally

    - by JK
    User preferences for my app is store in NSUserDefaults. This includes a "theme" preference, which needs to be accessed frequently by multiple classes. I would prefer not to call "[[NSUserDefaults standardUserDefaults] objectForKey:..." repeatedly as it makes for inconcise code and I assume will incur overhead. What is the preferred and most concise method for accessing preferences in any class?

  • Update text on CCLabelTFF end in bad access?

    - by TheDeveloper
    I'm doing a little game in Coco2D and I have a countdown clock Note: As I am just trying to fix a bug, I am not working on cleanup so the timer can stop, etc. Here is my code I'm using to setup the label and start the timer: timer = [CCLabelTTF labelWithString:@"10.0000" fontName:@"Helvetica" fontSize:20]; timerDisplay = timer; timerDisplay.position = ccp(277,310); [self addChild:timerDisplay]; timeLeft = 10; timerObject = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; Note: timeLeft is a double This is updateTimers's code: -(void)updateTimer { NSLog(@"Got Called!"); timeLeft = timeLeft -0.1; [timer setString:[NSString stringWithFormat:@"%f",timeLeft]]; timerDisplay = timer; timerDisplay.position = ccp(277,310); [self removeChild:timerDisplay cleanup:YES]; //[self addChild:timerDisplay]; if (timeLeft <= 0) { [timerObject invalidate]; } } When I run this I toggle between crashing on this this: [timer setString:[NSString stringWithFormat:@"%f",timeLeft]]; and in the green arrow thing it gives Thread 1: EXEC_BAD_ACCESS (code=2, address=0x8) and 0x197a7ff: movl 16(%edi), %esi and in the green arrow thing it gives Thread 1: EXEC_BAD_ACCESS (code=2, address=0x8)

  • Collision detection problems...

    - by thyrgle
    Hi, I have written the following: -(void) checkIfLineCollidesWithAll { float slope = ((160-L1Circle1.position.y)-(160-L1Circle2.position.y))/((240-L1Circle1.position.x)-(240-L1Circle2.position.x)); float b = (160-L1Circle1.position.y) - slope * (240-L1Circle1.position.x); if ((240-L1Sensor1.position.x) < (240-L1Circle1.position.x) && (240-L1Sensor1.position.x) < (240-L1Circle2.position.x) || ((240-L1Sensor1.position.x) > (240-L1Circle1.position.x) && (240-L1Sensor1.position.x) > (240-L1Circle2.position.x))) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } else if (slope == INFINITY || slope == -INFINITY) { if (L1Circle1.position.y + 16 >= L1Sensor1.position.y || L1Circle1.position.y - 16 <= L1Sensor1.position.y) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorBad.png"]]; } else { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } } else if (160-L1Sensor1.position.y + 12 >= slope*(240-L1Sensor1.position.x) + b && 160-L1Sensor1.position.y - 12 <= slope*(240-L1Sensor1.position.x) + b) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorBad.png"]]; } else { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } } Basically what this does is finds m and b in the well known equation: y = mx + b and then substitutes coordinates of the L1Sensor1 (the circle I'm trying to detect if it it intersects with the line segment) to see if y = mx + b hold true. But, there are two problems, first, when slope approaches infinity the range of what the L1Sensor1 should "react" to (it "reacts" by changing its image) becomes smaller. Also, the code that should handle infinity is not working. Thanks for the help in advanced.

  • Tracing memory leaks

    - by iFloh
    My favorite candidate again. I am in the process of identifying memory leaks in my app (a puzzling challenge for a newbe like me). I am using the xCode leak analyzer, but what puzzles me is how to trace back a memory leak to its variable or value. Is there a pointer to the instances that have reserved a memory address where a leak is identifyed? How do I best go about it?

  • Dynamic name of NSMutableDictionary?

    - by Bruno
    Hi everyone I load from a txt file many info, and I would like, if possible, to dynamically create NSmutable dictionary with the elements of the txt. For example, each is like that: id of element | date | text What I'm asking is the equivalent of the NSString stringWithFormat:. Can we do the same for an Mutable Dictionary? To be more practical, let's say the NSString *date is equal to "23/12/2009" (for europe). I want to create a dictionary called 23/12/2009 without declaring *23/12/2009 but just something like dictionaryWithFormat: @"%@", date]; I'm stuck on this, and I don't even know if it is possible. If not, what's the best way to approach that? Thanks everyone Regards

  • How to resize a UISwitch?

    - by mshsayem
    I have made a custom UISwitch (from this post). But the problem is, my custom texts are a bit long. Is there any way to resize the switch? [I tried setBounds, did not work] Edit: Here is the code I used: @interface CustomUISwitch : UISwitch - (void) setLeftLabelText: (NSString *) labelText; - (void) setRightLabelText: (NSString *) labelText; @end @implementation CustomUISwitch - (UIView *) slider { return [[self subviews] lastObject]; } - (UIView *) textHolder { return [[[self slider] subviews] objectAtIndex:2]; } - (UILabel *) leftLabel { return [[[self textHolder] subviews] objectAtIndex:0]; } - (UILabel *) rightLabel { return [[[self textHolder] subviews] objectAtIndex:1]; } - (void) setLeftLabelText: (NSString *) labelText { [[self leftLabel] setText:labelText]; } - (void) setRightLabelText: (NSString *) labelText { [[self rightLabel] setText:labelText]; } @end mySwitch = [[CustomUISwitch alloc] initWithFrame:CGRectZero]; //Tried these, but did not work //CGRect aFrame = mySwitch.frame; //aFrame.size.width = 200; //aFrame.size.height = 100; //mySwitch.frame = aFrame; [mySwitch setLeftLabelText: @"longValue1"]; [mySwitch setRightLabelText: @"longValue2"];

  • How to tell if a user updated my app or installed a new one

    - by user310318
    I need a way to tell if the app being used by a user is a fresh new install (new user), or was a pre-existing user who updated. The previous app version did not track UDID's, and didn't save anything (it just ran as a simple app). Is there a way for an update to tell if the user previously installed the app? Even if that app didn't save anything into the documents folder, and the app didnt communicate with a server (UDID post)? (id like to be able to offer bonus features to my existing loyal users who had already installed the original app and updated) thanks!!
