아이폰 Animation 만들기 예제 따라하기

- UIView 클래스에 있는 Animation 기능을 사용하여 간단한 예제이다.

- Button을 누르면 Label이 Animation 기능으로 움직이게 된다.

- 화면 디자인

- Animation 만들기 순서

1. Xcode 실행
2. Single View Application
3. Project Name : “SimpleAni01”
4. storyboard에 Button과 Label 위치
5. Assistant Editor로 Label 드래그
6. “myLabel” 입력
7. Button을 Assistant Editor로 드래그 Connection을 Action으로 변경 “tapBtn” 입력 

8. ViewController.m 파일에 입력

-(IBAction) tapBtn {
myLabel.center = CGPointMake(50, 100); //숫자는 좌표!
[UIView beginAnimations: nil context:nil];
[UIView setAnimationDuration: 2];
myLabel.center = CGPointMake(160, 240); //숫자는 좌표!!
myLabel.transform = CGAffineTransformMakeRotation(270 * M_PI / 180); [UIView commitAnimations];

}

9. 실행 

- ViewController.m 소스코드

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize myLabel;

- (void)viewDidLoad

{

    [super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

}

- (void)viewDidUnload

{

    [self setMyLabel:nil];

    [super viewDidUnload];

    // Release any retained subviews of the main view.

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);

} else {

    return YES;

}

}

- (IBAction)tapBtn:(id)sender {

myLabel.center = CGPointMake(100, 100);

[UIView beginAnimations: nil context:nil];

[UIView setAnimationDuration: 1];

myLabel.center = CGPointMake(200, 200);

myLabel.transform = CGAffineTransformMakeRotation(240 * M_PI / 180); [UIView commitAnimations];

}

@end
