objective c - UIImageView not displaying image - iPhone SDK -


I am using AVFRMMwork to capture camera frames and I would like to process and display them in UIImageView, but there is some problem. I have a code:

A sample buffer was written when it is said that the delegate - (zero) CaptureOptput: (AVCaptureOutput *) CaptureApptput didOutputSampleBuffer: (CMSampleBufferRef) connection to the sampleBuffer: (AVCaptureConnection *) Connection {// NSLog (@ "Capturing \ n"); // Create a UIImage from sample buffer data UIImage * Image = [Self Image Entertainment Buffer: sampleBuffer]; NSLog (@ "Image:% F% F \ n", Image. Size.height, image.size.width); [ImageView Set Image: Image]; }

However, it will not be displayed. The correct size is shown in NSLog , and when I enter:

imageImage: [UIImage imageNamed: @ "SomethingElse.png"]];

In the viewDidLoad, an image is displayed correctly (so I know that UIImageView is correctly added).

Should not any work? I'm at a loss right now.

Cheers, Brett

What are you doing on this main thread? You can either use the main queue for the representative (undesirable, because you are already processing) or: 

  dispatch_async (dispatch_get_main_queue (), ^ {imageView.image = .. ;;});

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
