  • Lua-Objective-C bridge on the iphone

    - by John Smith
    I have partially ported the LuaObjCBridge to the iPhone. Most things work but there are still some issues I have to deal with. There are sections where #defines are defined with-respect-to intel or ppc. Is the ARM chip closer to intel or ppc? Here is the most relevant section where most of the defines are: #if defined(__ppc__)||defined(__PPC__)||defined(__powerpc__) #define LUA_OBJC_METHODCALL_INT_IS_SHORTEST_INTEGRAL_TYPE #define LUA_OBJC_METHODCALL_PASS_FLOATS_IN_MARG_HEADER #define LUA_OBJC_POWER_ALIGNMENT #elif defined(__i386__)||defined(__arm__) #warning LuaObjCBridge is not fully tested for use on Intel chips. #define LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY // Use this or the code was crashing for me for structs LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY_LIMIT #define LUA_OBJC_METHODCALL_USE_OBJC_MSGSENDV_FPRET #define LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY_LIMIT 8 #define LUA_OBJC_INTEL_ALIGNMENT #endif For now I added arm with i386, but I could be wrong

  • Why does my UI controls work on iPhone but not iPad?

    - by Andrew
    I have an iPhone app, which consists of a table view containing various custom UITableViewCells, with UISlider and UISwitch controls. When running the app on the iphone, I can move the slider and switches contained in each of the table cells. When I run the same app on the iPad. I can not. None of the controls within the table view will respond to touches. I have checked 'User Interaction Enabled' within the Interface Builder. Anybody got any suggestions of where I should be looking for the cause of different behavior between the iPhone and iPad, in respect to UIControls.

  • Template apps for iPhone

    - by rob
    Is there a good place to get starter apps for iPhone, where you choose from any of a large set of permutations?...for instance with a nav bar and a flip screen and a 3 deep table view, with Core Data support etc. I guess what I was hoping for is some kind of wizard where you can check a few boxes and have a working app as a starting point....but more than just the 3 or 4 choices that come with xCode. If not a wizard, just a nice set of a couple dozen permutations. Also....is there any good sample apps out there that show the difference between identical apps, one which uses Interface Builder and one not? Aside from being handy for myself, I'd think these would be great as a teaching tool. I've googled a bit and come up with nothing.

  • Best way to create Default.png image for iPhone app

    - by Alex
    Originally I though I'll just take a screenshot of my app on the iPhone then tweak it in Photoshop. The images should be 480 x 320 according to Apple doc, and the dimensions of my screenshot are 480 x 320. But, the screenshot contains notification area (where reception bars, battery life, etc. are displayed) So, if I chop that part off my image will be a bit shorter and not 480px high. What do I do? Submit a shorter image? Stretch it up so it's 480px but without the notification bar? Submit it with the notification bar in the image? How did you create your Default.png?

  • Why aren't Admob click callback delegate methods not getting called?

    - by executor21
    I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help.

(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSIndexPath *rowToSelect = indexPath; NSInteger section = indexPath.section; BOOL isEditing = self.editing; // If editing, don't allow notes to be selected // Not editing: Only allow notes to be selected if ((isEditing && section == ONE_SECTION) || (!isEditing && section != ONE_SECTION)) { [tableView deselectRowAtIndexPath:indexPath animated:YES]; rowToSelect = nil; } return rowToSelect; } it s being driving me nuts... thanks

  • Graph generation on iPhone

    - by Parrots
    Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone. If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?

  • plus minus table View cell

    - by user1748387
    I have the following code - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; UIImage * i1 = [UIImage imageNamed: @"inc_01.png"]; UIImage * i2 = [UIImage imageNamed: @"inc_02.png"]; UIImage * i3 = [UIImage imageNamed: @"inc_04.png"]; UIImage * i5 = [UIImage imageNamed: @"inc_05.png"]; UIImage * i6 = [UIImage imageNamed: @"inc_06.png"]; UIImage * i7 = [UIImage imageNamed: @"inchd.png"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } if(indexPath.row == 0) { UIImageView * header= [[UIImageView alloc] initWithImage: i1]; cell.backgroundView = header; // Configure the cell… } else if (indexPath.row == 2) { UIImageView *backgroundCellImage=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 280, 11)]; backgroundCellImage.image=[UIImage imageNamed:@"inc_06.png"]; [cell.contentView addSubview:backgroundCellImage]; } else { // Configure the cell… UIImageView *imageView = [[UIImageView alloc] initWithImage: i3]; cell.textLabel.text = @"text"; UIImageView *backgroundCellImage=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 57, 46)]; backgroundCellImage.image=[UIImage imageNamed:@"inc_02.png"]; UIImageView *backgroundCellImage2=[[UIImageView alloc] initWithFrame:CGRectMake(223, 0, 57, 46)]; backgroundCellImage2.image=[UIImage imageNamed:@"inc_04.png"]; UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(57, 0, 166, 46)]; label.text = @"wow"; [cell.contentView addSubview:backgroundCellImage]; [cell.contentView addSubview:backgroundCellImage2]; [cell.contentView addSubview:label]; } return cell; } that basically creates a table view and puts an image to the left and right of each cell. I want it so that people can click on the left or right image in each cell, and something different happens based on the cell number. So if they click on the left image for cell in row 1, a function gets call with the row number they clicked on, and an indicator telling me they clicked on the left image and not the right image. How can I do that using objective-c?

    I'm using +[NSUserDefaults standardUserDefaults] to store application settings. This consists of roughly a dozen string values. Is it possible to delete these values permanently instead of just setting them to a default value?

  • CADisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • UITableView - centering of Sections

    - by Raj
    Hi all, I am using a table view with its style set as "Grouped". I have only 2 sections to be displayed in the table view and the table view does not occupy full iPhone screen (It has some other views with it). So I would like to display those 2 sections centered in the table view rather than displaying the sections from the top of table view. One round about way is to set header and footer of the table view appropriately. But the disadvantage of this is, each sections will be equidistant (looks awkward!). Anybody with solutions to it? Thanks, Raj
