  • 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

  • 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.

  • UIActionSheet Cancel button keeps crashing my app

    - by user337174
    I am really puzzeled by this one. I have set up two UIActionSheets in my application. They work perfectly fine until you use the cancel button in the UIActionSheets. When i navigate away from the page the UIAactionSheet returns too it crashes my app. Does anyone have any ideas as too why? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button phoneActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; phoneActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [phoneActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [phoneActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (actionSheet == phoneActionSheet) { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } } }

  • 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.

  • 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...

  • Loading local html pages in UIWebView

    - by mwt
    I'm working with a UIWebView loading local (i.e. in the source bundle) html pages, ala Apple's Transweb example. Loading the first page is trivial. However, I have added a second html page and linked to it from the first. Attempting to link to a second page doesn't seem to work. Anyone know how to make this work? Thanks.

  • Dynamic title like in the Notes app

    - by Fran
    Hi, when the user enters text in a uitextview I would that the title of the navigation bar changed dynamically like it happens in the Notes app. How can I achieve this? I think a label is used, don't I? Thanks Fran EDIT: I know how change the title of a navigation bar, but how do this in a such way that the textview is tied to the title, so while user enters the first line of text in the same moment the title changes (letter by letter)?

  • 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?

  • How to respond to any kind of interruption?

    - by mystify
    My app is playing a pretty complex animation. It's like a flipbook. What I do is: I have a huge loop with selectors, and after every delayed call the next one is called. Now someone calls the user and the device suddenly shows up this fat green status bar and maybe some big pick-up-the-phone-call overlay. Or: The alarm clock rings, and a big alert sheet appears in front of just about everything. It would be great to just pause the whole animation in case of ANY interruption. Probably I've also missed like 5 more possible interruptions. How are you doing that? How do you get notified for all interruptions and then call one single -stopEverything method?

  • Playing animations in sequence in objecive c

    - by Ohmnastrum
    I'm trying to play animations in sequence but i'm having issues playing them as a for loop iterates through the list of objects in an array. it will move through the array but it won't play each one it just plays the last... -(void) startGame { gramma.animationDuration = 0.5; // Repeat forever gramma.animationRepeatCount = 1; int r = arc4random() % 4; [colorChoices addObject:[NSNumber numberWithInt:r]]; int anInt = [[colorChoices objectAtIndex:0] integerValue]; NSLog(@"%d", anInt); for (int i = 0; i < colorChoices.count; i++) { [self StrikeFrog:[[colorChoices objectAtIndex:i] integerValue]]; //NSLog(@"%d", [[colorChoices objectAtIndex:i] integerValue]); sleep(1); } } it moves through the whole cycle really fast and sleep isn't doing anything to allow it to play each animation... any suggestions?

  • How do you call a method for an Objective-C object's superclass from elsewhere?

    - by executor21
    If you're implementing a subclass, you can, within your implementation, explicitly call the superclass's method, even if you've overridden that method, i.e.: [self overriddenMethod]; //calls the subclass's method [super overriddenMethod]; //calls the superclass's method What if you want to call the superclass's method from somewhere outside the subclass's implementation, i.e.: [[object super] overriddenMethod]; //crashes Is this even possible? And by extension, is it possible to go up more than one level within the implementation, i.e.: [[super super] overriddenMethod]; //will this work?

  • How to compensate the flipped coordinate system of core graphics for easy drawing?

    - by mystify
    It's really a pain, but always when I draw an UIImage in -drawRect:, it's upside-down. When I flip the coordinates, the image draws correctly, but at the cost of all other CG functions drawing "wrong" (flipped). What's your strategy when you have to draw images and other things? Is there any rule of thumb how to not get stuck in this problem over and over again? Also, one nasty thing when I flip the y-axis is, that my CGRect from the UIImageView frame is wrong. Instead of the origin appearing at 10,10 upper left as expected, it appears at the bottom. But at the same time, all those normal line drawing functions of CGContext take correct coordinates. drawing a line in -drawRect with origin 10,10 upper left, will really start at upper left. But at the same time that's strange, because core graphics actually has a flipped coordinate system with y 0 at the bottom. So it seems like something is really inconsistent there. Drawing with CGContext functions takes coordinates as "expected" (cmon, nobody thinks in coordinates starting from bottom left, that's silly), while drawing any kind of image still works the "wrong" way. Do you use helper methods to draw images? Or is there anything useful that makes image drawing not a pain in the butt?

  • Is a tab bar configuration view can be customized ?

    I have an application with 8 tabbar items in the tabbar controller. Is there a way I can customize the layout of the "...
