  • Get tableView:heightForRowAtIndexPath: to happen after tableView:cellForRowAtIndexPath:?

    - by Triz
    I've got some UITableViewCells that need to change their height depending on the length of the strings inside. I'm calculating the necessary height inside tableView:cellForRowAtIndexPath:, and then storing it in a variable (self.specialRowHeight). Then I've got: - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section == SPECIAL_SECTION) { return self.specialRowHeight; } else { return 44; } } Except that seems to be getting called before the tableView:cellForRowAtIndexPath: bit, so it's always zero. Is there a way around this, or perhaps a different way to do it? Thanks!

  • 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.

  • UIWebView - remote html loading local images

    - by AragornSG
    I'm trying to develop an application using UIWebView. The app is loading remote URL's, so in order to make it quick I want it to use the images included in the application bundle. I was wondering if there is a way to do it without forcing the application to manually replace the address of each image to point into local resources?

  • Change the contents of a UITableView via a swipe?

    - by Mark
    Im currently using a UITableView like any other, and I am researching into the ability to perform a swipe gesture on the screen, which will then shift the contents of the visible table over to display new content for example: swiping right-to-left on the screen would change (via animation) the contents within each of the cells on screen to show new data. What I can do is detect a swipe on the cells, or perhaps on the UITableViewController, but what I dont know how to do two fold: 1) Change data in all cells (could you have a set of hidden views within a custom table cell that animate in and out of each cell per swipe?) 2) How can you do this to all cells? Thanks a lot Mark

  • Custom UIButton + subviews = no events

    - by user281300
    Basically I have a custom UIButton and this custom button contains subviews. If I add those subviews to my uibutton, then the button stops responding to event changes. I.e if I click on it it doesn't respond to the selector. I have everything set as userInteractionEnabled. I also tried adding touchbegan and this is working. If I remove those subviews, the UIButton works again. Any help would be greatly appreciated. Cheers.

  • Duplicate Method Names - Objective-c

    - by evanchri
    Why does this compile with out any errors or warnings? @interface ObjectTest : NSObject { } -(void)iAmADoubleMethod; -(void)iAmADoubleMethod; @end @implementation ObjectTest -(void)iAmADoubleMethod { NSLog(@"IAmADoubleMethod"); } @end I came across this in a project I am working on. I come from a C++ background, so I figure I would get at least a warning for this. Not only would I like to know why it complies but could this code cause any problems? Thanks.

  • Creating UIButton using helper method

    - by ddawber
    I have a subclass of UITableView and in it I want to generate number of labels that share the same properties (font, textColor, backgroundColor, etc.). I decided the easiest way to achieve this would be to create a helper method which creates the label with some common properties set: - (UILabel *)defaultLabelWithFrame:(CGRect)frame { UILabel *label = [[UILabel alloc] initWithFrame:frame]; label.font = [UIFont fontWithName:@"Helvetica" size:14]; label.textColor = [UIColor colorWithWhite:128.0/255.0 alpha:1.0]; label.backgroundColor = [UIColor clearColor]; return label; } I use the method like this: UILabel *someLabel = [self defaultLabelWithFrame:CGRectMake(0,0,100,100)]; [self addSubview:someLabel]; [someLabel release]; My concern here is that when creating the label in the method it is retained, but when I then assign it to someLabel, it is retained again and I have no way of releasing the memory when created in the method. What would be best the best approach here? I fee like I have two options: Create a subclass of UILabel for the default label type. Create an NSMutableArray called defaultLabels and store the labels in this: - (UILabel *)defaultLabelWithFrame:(CGRect)frame { UILabel *label = [[UILabel alloc] initWithFrame:frame]; label.font = [UIFont fontWithName:@"Helvetica" size:14]; label.textColor = [UIColor colorWithWhite:128.0/255.0 alpha:1.0]; label.backgroundColor = [UIColor clearColor]; [defaultLabels addObject:label]; [labels release]; //I can release here return [defaultLabels lastObject]; //I can release defaultLabels when done } I appreciate your thoughts. Cheers.

  • Is a tab bar configuration view can be customized ?

    - by Dirty Henry
    I have an application with 8 tabbar items in the tabbar controller. Is there a way I can customize the layout of the "... (more)" view in which you can configure which tab bar items should appear in the main tab bar. It seems to be a table view controller but i'd like to use custom cell views and a background image.

  • Retrieving a unique result set with Core Data

    - by randombits
    I have a core data based app that manages a bunch of entities. I'm looking to be able to do the following. I have an entity "SomeEntity" with the attributes: name, type, rank, foo1, foo2. Now, SomeEntity has several rows if when we're speaking strictly in SQL terms. What I'm trying to accomplish is to retrieve only available types, even though each instance can have duplicate types. I also need them returned in order according to rank. So in SQL, what I'm looking for is the following: SELECT DISTINCT(type) ORDER BY rank ASC Here is the code I have so far that's breaking: NSError *error = NULL; NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setReturnsDistinctResults:YES]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObjects:@"type", @"rank", nil]]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"SomeEntity" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // sort by rank NSSortDescriptor *rankDescriptor = [[NSSortDescriptor alloc] initWithKey:@"rank" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:rankDescriptor,nil]; [fetchRequest setSortDescriptors:sortDescriptors]; [sortDescriptors release]; [rankDescriptor release]; NSArray *fetchResults = [managedObjectContext executeFetchRequest:fetchRequest error:&error]; [fetchRequest release]; return fetchResults; Right now that is crashing with the following: Invalid keypath section passed to setPropertiesToFetch:

  • Sending custom app logs to developer

    - by Templar
    I'm planning to release a new app in the future. I have a custom logging function which logs some application data (not crashes) into a file (location manager state, app foreground-background transitions, main actions...). These logs helped me a lot to debug problems which were app-related, but not causing a crash. Until now these were in the documents directory (shared in iTunes) and the testers sent them to me after they saw some incorrect behaviors, however I don't want to share them anymore because this directory contains the app's database too. I'd like to obtain these logs even when the app will be on App Store, but I don't know how this should be done. As I wrote, it is a new app and even after the test phase may exist minor bugs. I know that the users can report problems in iTunes or on the Dev site, but without a detailed scenario or log it is really hard to correct a bug. Should I make some kind of in-app bug report functionality (even if this creates a wrong user impression) ? How is this usually handled ? Thanks

  • iPad device orientation is null?

    - by Brodie4598
    ([UIDevice currentDevice].orientation); using the above code in my app, all i get is 0 (unknown) is there something thats going wrong here? Seems pretty straightforward edit: more research led me to the problem with using device orientation early in the app, which I am doing. However when I instead use interfaceOrientation, it always returns 1 (portrait)

  • Why am I getting a EXC_BAD_ACCESS in a NSTimer selector?

    - by AngeDeLaMort
    I've got quite a weird problem. To make it short, i'll write some pseudo-code: init: create a dictionary and insert n elements. create a "repeat timer" and add it to the currentRunLoop using the timerRefresh selector. timerRefresh: using a list of keys, find the items in the dictionary if the item exists -> call a function So, for an unknown reason, I get an EXC_BAD_ACCESS when I do: [item function]; But I traced the address I got from the dictionary items and it's ok. The ref count of the items in the dictionary is still 1. The {release, dealloc} of the items in the dictionary aren't called. Everything seems fine. Also, to make it worst, it works for some items. So, I'm wondering if there is a threading problem? or something else obscure? The callstack is quite simple: #0 0x93e0604b in objc_msgSend_fpret #1 0x00f3e6b0 in ?? #2 0x0001cfca in -[myObject functionm:] at myObject.m:000 #3 0x305355cd in __NSFireTimer #4 0x302454a0 in CFRunLoopRunSpecific #5 0x30244628 in CFRunLoopRunInMode #6 0x32044c31 in GSEventRunModal #7 0x32044cf6 in GSEventRun #8 0x309021ee in UIApplicationMain #9 0x000027e0 in main at main.m:14 So, any suggestion where to look would be appreciated.

  • 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:"?
