views - Problems Removing Subview from SuperView - Objective-C -


not sure why isn't working remove added subview parent view. want removed if longpress action ended. tested nslog , know gestures registering ended, it's not removing subview.

-(void)addsubview:(uilongpressgesturerecognizer *)gesture {     nsarray *subviewarray = [[nsbundle mainbundle] loadnibnamed:@"overlayview" owner:self     options:nil];     uiview *subview = [subviewarray objectatindex:0];      if (gesture.state == uigesturerecognizerstatebegan) {         [self.view addsubview:subview];         }     if (gesture.state == uigesturerecognizerstateended) {         [subview removefromsuperview];         }     }

desired functionality:

longpress starts: add subview.
longpress ends: remove subview.

i hope resolve issue declaring uiview *subview in .h file , putting below lines in viewdidload:

 nsarray *subviewarray = [[nsbundle mainbundle] loadnibnamed:@"overlayview" owner:self     options:nil];     uiview *subview = [subviewarray objectatindex:0];

and then: 

-(void)addsubview:(uilongpressgesturerecognizer *)gesture {     if (gesture.state == uigesturerecognizerstatebegan) {         [self.view addsubview:subview];         }     if (gesture.state == uigesturerecognizerstateended) {         [subview removefromsuperview];         }     }

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
