ios6

What is the correct way to compare, or test, for a particular color attribute of an NSAttributed string? As an example, I'd like to know if the text selection has red text. I have tried several approaches, as you can see below, but none of them ever results in a match. I see the text turn red on screen, and logging the attribute returns: UIDeviceRGBColorSpace 1 0 0 1 - (BOOL)isRedWithAttributes:(NSDictionary *)attributes { BOOL isRedWithAttributes = NO; if (attributes != nil) { // if ( [attributes objectForKey:NSForegroundColorAttributeName] == [UIColor redColor] ) // if ( [attributes

I had a project which contains lots of UIButton, using xcode 4.5 and storyboard and ARC. after testing in ios6, everything goes fine. But in ios5, UIButton touch up inside event not working, the action not called. I tried to use touch down and it works. However, I have a lot of UIButton, I cannot change that one by one. what's more, the touch down event does give a good experience. I used code below in many of my view controllers: in viewDidLoad: UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)]; [self.view addGestureRecognizer

I'm looking to perform a segue to replace the window's root view controller by another view controller using a curl up animation. The idea is that I have a SplashViewController being displayed for a couple of seconds before transitioning ( performSegueWithIdentifier: ) to the next one, LoginViewController , using the curl up animation. I've created a custom UIStoryboardSegue class called AnimatedSegue . Here is the code of the overridden perform method: - (void)perform { UIViewController *source = self.sourceViewController; UIViewController *destination = self.destinationViewController;

I need gl_FragColor to "paint" floating point values, which also can be negative (x < 0) and > 1.0. I then want to use the color attachement of the FBO this values where rendered to and use it as a texture in another FBO. Now I have read on http://www.khronos.org/opengles/sdk/docs/man/ (under glTexImage2D) that all values are clamped to a range of [0, 1] and also I didn't find a glClampColor instruction. Is there a possibility to find a workaround here or does somebody have an idea which could help me with my problem? :) SOLVED It is possible and the values are not clamped to [0, 1] at all,

Am displaying images in a table view controller where the images are rendered from the URL as XML file. It works well with listing images as scroll view. Now i want to select a particular image and the window should show the selected Cell images alone. For this do i need to get the Cell value. If so how can i get the particular cell value and display its corresponding images as a collection view in next window. Kindly suggest me an idea. For your better understanding i pasted below an image how my storyboard currently looks and how i need an output. Hope you understand my problem. Vinayak Kini
