Animation, one thing that make iPhone a cool device. So get ready to make your apps as a cool app through use of animation.

Suppose you want a view to slide in from right side of screen and went toward left side.For that purpose we can use UIViewAnimation provided in IOS.

Step1: First add your view as subview

[self.view addSubview:bGView];

Step 2:get height of device screen area

CGRect screenFrame = [[UIScreen mainScreen] bounds];

Step3: give view a frame outside the visible screen area

bGView.frame = CGRectMake(420,0,320,screenFrame.size.height);

Step 4:Add animation code as shown below code snippet, to bring subview/view to center of screen

[UIView animateWithDuration:2.0
        animations:^{ 
          bGView.frame = CGRectMake(0,0,320,screenFrame.size.height);
           } 
           completion:^(BOOL finished){
                    ;
                }];

Step 5: To move View out of screen toward left hand side use given below code snippet

[UIView animateWithDuration:2.0
        animations:^{ 
          bGView.frame = CGRectMake(-420,0,320,screenFrame.size.height);
          } 
          completion:^(BOOL finished){
                    ;
                }];
