iOS7 - Setting selectedIndex of UITabBarController breaks touch events along right-hand edge of screen?

阅读更多关于 iOS7 - Setting selectedIndex of UITabBarController breaks touch events along right-hand edge of screen?

I've hit a weird problem with UITabBarController on iOS7 and can't seem to find a workaround, so any help would be welcome! Scenario: Navigation-based app using landscape orientation on iPad. App consists of a main view, and a second view which is a UITabBarController. TabBarController has two tabs. First view has two buttons - each button performs a segue to the tab bar controller and sets a different tab as selected. (i.e. button1 selects the first tab, and button2 selects the second tab). Setting the tab is done in prepareForSegue by calling setSelectedIndex on the tab bar controller.

How to reset AnimationDrawable

阅读更多关于 How to reset AnimationDrawable

I have to animate a circular count down timer and I'm doing it by animating the background of an ImageView using AnimationDrawable (each image has the according slice of the circle removed). The problem is that the user has the ability to pause this animation, so I have to reload the animation but then a problem appears. I've tried setting the the animation to null, setting the background of the ImageView to null, setting the visibility of the animation, but practically nothing helped, because number of frames remains the same. I have to find a workaround for deleting all frames and adding new

How to know total number of Frame in a file ( .avi) through Python using open cv module. If possible what all the information (resolution, fps,duration,etc) we can get of a video file through this. With a newer OpenCV version (I use 3.1.0) it works like this: import cv2 cap = cv2.VideoCapture("video.mp4") length = int(cap.get(cv2.CAP_PROP_FRAME_COUNT)) print( length ) And similar for other video properties cv2.CAP_PROP_* berak import cv2 cap = cv2.VideoCapture(fn) if not cap.isOpened(): print "could not open :",fn return length = int(cap.get(cv2.cv.CV_CAP_PROP_FRAME_COUNT)) width = int(cap.get

问题 Looking at options for embedding the 3D Secure page inside my own order form, I came across the following: "Some commerce sites will devote the full browser page to the authentication rather than using a frame (not necessarily an iFrame, which is a less secure object anyway)." from http://en.wikipedia.org/wiki/3-D_Secure Can someone give me the lowdown as to why iframes are less secure, and cause problems, as opposed to normal frames? And what are the basic differences? The way I see it,

What is the height of Navigation Bar in iOS 7?

阅读更多关于 What is the height of Navigation Bar in iOS 7?

问题 I 've just created a simple iOS 7 app using the default Master Details template. In the MasterViewController.m , viewDidAppear method, I logged for self.navigationController.navigationBar.frame.size.height self.navigationController.navigationBar.frame.origin.y and received 44 and 20 accordingly. This seems weird, because from what I read, the Navigation Bar in iOS 7 should be 64 point height and start at 0 point, so that it sits underneath the Status bar. What I read are 1) iOS 7 UI

Which icon sizes to use with a JFrame's setIconImages() method?

阅读更多关于 Which icon sizes to use with a JFrame's setIconImages() method?

Does anyone know which icon sizes to use with the setIconImages() (PLURAL) method for a jFrame so that my app icons display well on all platforms and in all contexts (e.g., window icon, taskbar icon, alt-tab icon, etc.)? I've found an example that uses a 16px-by-16px and a 32px-by-32px image, but do I need to go any bigger? To test, I have also tried adding 64px and 128px versions to the List passed to setIconImages(), but these do not seem to be used on my Windows 7 machine. However, I cannot test easily on other machines, so am wondering if anyone knows which sizes I should include? Alan
