IOS development instance View for animation effect

IOSDevelopment InstanceViewImplementationAnimationThe effect is what we will introduce in this article.IosIn applications, you can often see a click button, a view gradually pops up, and a button, the view slowly scales back. ThisAnimationThe effects are often used in ios. The following is a small example I wrote. The interface effects are as follows:

 

The specific implementation process is as follows:

Create a project.

Use Interface Builder to add a button and a view to change the background color of the view.

Declare in the header file:

 
 

  
  
# Import <UIKit/UIKit. h>
  
  
 
  
  
@ Interface ipad_scrollViewViewController: UIViewController {
  
  
 
  
  
IBOutlet UIButton * myButton;
  
  
UILabel * tableView;
  
  
IBOutlet UIView * myView;
  
  
}
  
  
@ Property (nonatomic, retain) UIButton * myButton;
  
  
@ Property (nonatomic, retain) UIView * myView;
  
  
-(IBAction) onClickButton :( id) sender;
  
  
@ End
  
  
 
  
  
Connect components in IB with related objects.
  
  
 
  
  
Implementation Code:
  
  
 
  
  
# Import "ipad_scrollViewViewController.h"
  
  
@ Implementation ipad_scrollViewViewController
  
  
@ Synthesize myButton, myView;
  
  
-(Void) viewDidLoad {
  
  
[Super viewDidLoad];
  
  
}
  
  
-(BOOL) shouldAutorotateToInterfaceOrientation :( UIInterfaceOrientation) interfaceOrientation {
  
  
Return YES;
  
  
}
  
  
 
  
  
-(Void) didReceiveMemoryWarning {
  
  
[Super didReceiveMemoryWarning];
  
  
}
  
  
 
  
  
-(Void) viewDidUnload {
  
  
Self. myButton = nil;
  
  
Self. myView = nil;
  
  
}
  
  
-(Void) dealloc {
  
  
[Self. myView release];
  
  
[Self. myButton release];
  
  
[Super dealloc];
  
  
}
  
  
-(IBAction) onClickButton :( id) sender
  
  
{
  
  
CGContextRef context = UIGraphicsGetCurrentContext ();
  
  
[UIView beginAnimations: @ "Curl" context: context];
  
  
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
  
  
[UIView setAnimationDuration: 0.5];
  
  
CGRect rect = [myView frame];
  
  
CGRect rect1 = [myButton frame];
  
  
If (rect. origin. x> 0 ){
  
  
Rect. origin. x = 26366f-rect. size. width;
  
  
Rect1.origin. x = 267.0f-rect. size. width;
  
  
} Else {
  
  
Rect. origin. x = 26366f;
  
  
Rect1.origin. x = 267.0f;
  
  
}
  
  
[MyButton setFrame: rect1];
  
  
[MyView setFrame: rect];
  
  
[UIView commitAnimations];
  
  
}
  
  
@ End

Although the above Code can move a view, one problem is that a view cannot be clicked if it is in the middle of the screen, from scratch and an animation that moves from one side to the other.
