animation - UITableView display distorted before setAnimationTransition during view swap -

-

Greetings! I am trying to borrow visual flip concept from Apple's The Elements sample app. This sample employs a container UIView in which you can see between two sub-views Can swap. The flip is achieved by setting the setAnimationTransition: forView: cache: and each subview. Generally, flip works and I have two scenes (with a UITableView header / footers, and a MKMapView ). However, different (consecutively selected) areas of my table view have been erased (using the background color of the table view), and why not before I have flipped the table view and Understands

I can not find anything unusual about the table view in the context of drawing. In the case of sample app, the scene has been drawn from scratch, but I hope it will not work for it! I'm really hoping that this is something simple - maybe a UITableView property setting?

Thank you for the appreciation of the clue!

Update: When I slow down the animation, I get the information to get upset (though I still do not know why). My table title view includes an image view and label view. Now, imagine CGRact for both of those ideas (without any visible content, just a background color) table view Further down, above the table rows

This is another part of the real estate which comes from the table view cell, a custom height (the text in it) To the size of Was determined.

I dropped my code (where the size of the things, what is manufactured and what is) is an inefficient number of breakpoints, and one is not killed during their transition.

I also tried to keep my table inside of a UIView and there was no difference in the targeting for the infection.

From API docs:

Caching can improve performance but if you set this parameter to Yes, you will see the sequence or its subviews Should not be updated. Updating the scene and its sub-scenes may interfere with the caching behavior and during the animation the scene content can be sung incorrectly (or in the wrong location). To update this view you will have to wait until the transition ends.

All this is well and good, but I am not updating any thoughts or subviews during the transition. (At least not on purpose! Again, see note about breakpoint. Nothing found.)

Amazing.

Answer: In this case, it only happens ... Simulator ! On the device, it's okay.

I was thinking that such a mill transition would be of a kind that would equally present on the simulator and the device.

I was wrong. So if you ever see the transition error on the simulator, then hang it there. It can be fine after all.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
