  • Secondary thread causes startup delay

    - by JK
    In my didFinishLaunchingWithOptions method I spawn a thread to perform some maintenance on my core data store. However, this increases the startup time by half a second. The startup view is a tableview which draws its content from the same store. If I let the thread sleep for a second, the startup time improves drastically. I would like to understand why the second thread is blocking/delaying the main thread. Is it because both are trying to access the store (The second thread has its own store coordinator and context) or another reason (e.g. dont spawn threads in didFinishLaunching)?

I just want to track the touches for my two buttons, which is a sprite, but whenever I have another touch other than my first two touches, it affects my touch with my button. Is there a way to get rid of that third touch? I wish you could help me with this problem.Thank You!

  • Can I refer to NSDictionary items numerically?

    - by cannyboy
    I'm trying to set up a UITableView which acts as a form. Each cell has within it a UILabel and a UITextField, so one cell is: Name <enter name> ^ ^ UILabel UITextField Now, I'm trying to populate the UILabel and the UITextField from a NSDictionary (from a plist), where it's organized like so: Root Type Value Name String Address String City String etc But in order to get the right labels and textfields in the cellForRowAtIndexPath method, I would have to refer to the Dictionary numerically. Is there any way to do that?

  • 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.

  • How do I create an image for a UITableViewCell dynamically

    - by Xetius
    I want to dynamically create an image for a UITableViewCell which is basically a square with a number in it. The square has to be a colour (specified dynamically) and contains a number as text inside it. I have looked at the CGContextRef documentation, but can't seem to work out how to get the image to fill with a specified certain colour. This is what I have been trying so far. -(UIImage*)createCellImageWithCount:(NSInteger)cellCount AndColour:(UIColor*)cellColour { CGFloat height = IMAGE_HEIGHT; CGFloat width = IMAGE_WIDTH; UIImage* inputImage; UIGraphicsBeginImageContext(CGSizeMake(width, height)); CGContextRef context = UIGraphicsGetCurrentContext(); UIGraphicsPushContext(context); // drawing code goes here // But I have no idea what. UIGraphicsPopContext(); UIImage* outputImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return outImage; }

  • 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

  • Interface Builder layout ViewController with its own nib

    - by Sean Clark Hess
    I would like to be able to decide where a sub view is placed, when that view is controlled by its own view controller. This happens frequently on the iPad when you have a semi-complicated view that doesn't fill the entire screen. So, imagine that I want the sub view controller's nib to decide its own width, components, connections, etc, while the parent nib would decide where that view/nib would be placed. I'd really like to lay it out visually instead of programatically. How can I?

  • Loading UINavigationController subclass from a Nib

    - by Rits
    My situation is as follows: My class SettingsViewController is a subclass of UINavigationController. That class contains the logic of its rootViewController. For example, it acts as the delegate and data source for two table views in that root view controller. I have no problem setting this up programmatically. In the initializer of SettingsViewController, I can create an additional UIViewController to serve as the root view controller, position the table views in its view, and set their delegates and data sources to self. But I want to load that root view via a Nib. The problem is, I do not know how to connect that Nib with my SettingsViewController, how to set the delegates and data sources. The SettingsViewController is not accessible from within the Nib. 'File Owner' represents the root view controller, not the SettingsViewController. How do I access my UINavigationController subclass from within my root view controllers Nib? Thanks in advance.
