objective c - How can I make an NSDictionary contain a selector as one of its values? -

-

यह कोड एक UITableViewController subclass दृश्यडिडलोड विधि में है। UITableViewController उप-वर्ग में एक परीक्षण विधि है।

यह अपवाद फेंके बिना क्रैश करता है। 

  id dict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: @ "कुछ पाठ", @ " Text ", @selector (test), @" selector ", शून्य]

pix0r का समाधान अच्छा है, लेकिन मैं आमतौर पर तारों का उपयोग करना पसंद करता हूं क्योंकि वे सीरियलाइजेशन के लिए अधिक लचीला हैं और डीबग आउटपुट में पढ़ने में आसान शब्द बनाते हैं। 

  // सेट चयनकर्ता एसईएल इन सिलेक्टर = @ सिलेक्टर ( कुछ कुछ:); NSString * selectorAsString = NSStringFromSelector (इनसॉल्टर); Id dict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: @ "कुछ पाठ", @ "पाठ", चयनकर्ता एस्टस्ट्रिंग, @ "चयनकर्ता", शून्य]; // चयनकर्ता एसईएल आउट चयनकर्ता को पुनः प्राप्त करें = NSSelectorFromString ([dict objectForKey: @ "चयनकर्ता"]);

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...

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...
