ios - Not able to move two images using uipangesturerecogniser -


i want move 2 images same uipangesturerecognizer , able move first image, try move second image first 1 goes original position. want first image retain it's after changed position.

-(void) viewwillappear:(bool)animated {     uipangesturerecognizer *pan = [[uipangesturerecognizer alloc] initwithtarget:self      action:@selector(handlepansuper:)];     [self.view addgesturerecognizer:pan]; }  - (void)handlepansuper:(uipangesturerecognizer *)sender     {      static uiimageview *viewtomove;      static cgpoint  originalcenter;      if (sender.state == uigesturerecognizerstatebegan)     {     cgpoint location = [sender locationinview:self.view];      if (cgrectcontainspoint(self.imageview.frame, location))     {         viewtomove = imageview;         originalcenter = viewtomove.center;     }     else if (cgrectcontainspoint(self.image2.frame, location))     {         viewtomove = image2;         originalcenter = viewtomove.center;     }     else     {         viewtomove = nil;     }      if (viewtomove)     {          viewtomove.alpha = 0.8;         [viewtomove.superview bringsubviewtofront:viewtomove];         nslog(@"hi being touched.");      }  }  if (sender.state == uigesturerecognizerstatechanged && viewtomove != nil)     {     cgpoint translation = [sender translationinview:self.view];     viewtomove.center = cgpointmake(originalcenter.x + translation.x, originalcenter.y +                                        translation.y);   } else if ((sender.state == uigesturerecognizerstateended ||           sender.state == uigesturerecognizerstatefailed ||           sender.state == uigesturerecognizerstatecancelled) && viewtomove != nil) {     // whatever post dragging want, e.g.     // snap piece place         // cgpoint center = viewtomove.center;         //viewtomove.center = center;          viewtomove.alpha  = 1.0;          viewtomove = nil;   } }

you setting gesture recognizer in superview. why? set inside views trying move, it's easier , less strange behaviors edited code, see below (not tested)

-(void) viewwillappear:(bool)animated {     uipangesturerecognizer *pan = [[uipangesturerecognizer alloc] initwithtarget:self      action:@selector(handlepansuper:)];     self.imageview.userinteractionenabled = self.image2.userinteractionenabled = yes;     [self.imageview addgesturerecognizer:pan];     [self.image2 addgesturerecognizer:pan]; }  - (void)handlepansuper:(uipangesturerecognizer *)sender {     uiimageview *viewtomove = (uiimageview*)sender.view;     cgpoint  originalcenter = viewtomove.center;      if (sender.state == uigesturerecognizerstatebegan)     {         cgpoint location = [sender locationinview:self.view];          viewtomove.alpha = 0.8;         [viewtomove.superview bringsubviewtofront:viewtomove];         nslog(@"hi being touched.");      }     else if (sender.state == uigesturerecognizerstatechanged)     {         cgpoint translation = [sender translationinview:self.view];         viewtomove.center = cgpointmake(originalcenter.x + translation.x, originalcenter.y +                                        translation.y);      }     else if ((sender.state == uigesturerecognizerstateended ||           sender.state == uigesturerecognizerstatefailed ||           sender.state == uigesturerecognizerstatecancelled))     {     // whatever post dragging want, e.g.     // snap piece place         // cgpoint center = viewtomove.center;         //viewtomove.center = center;          viewtomove.alpha  = 1.0;         viewtomove = nil;     } }

please try this, , let me know if worked.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
