移動UIButton 10px並打開新的ViewController

我是新手在iOS開發，這是我的第一個問題。移動UIButton 10px並打開新的ViewController

我想創建「動畫」。

當我點擊UIButton時，我想慢慢地（約0.5秒）將它向下移動10px，當我舉起我的手指時，我想打開新的viewController。

我製作了東西但我不知道如何製作「動畫」。

UIImage *normalImage = [UIImage imageNamed:@"FirstImage"];   
    UIButton *firstButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
    firstButton.frame = CGRectMake(31, 194, normalImage.size.width, normalImage.size.height); 
    [firstButton setImage:normalImage forState:UIControlStateNormal]; 
    [firstButton addTarget:self action:@selector(showSecondViewController) forControlEvents:UIControlEventTouchUpInside]; 
    [self.view addSubview:firstButton]; 


- (void)showSecondViewController; { 
    SecondViewController *secondViewController = [[SecondViewController alloc] init]; 
    secondViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
    [self presentModalViewController:secondViewController animated:YES]; 
    [progressViewController release]; 
}

[UIView animateWithDuration:(NSTimeInterval)duration animations:^(void) { 
    //put your animation result here 
    //then it will do animation for you 
} completion:^(BOOL finished){ 
    //do what you need to do after animation complete 
}];

例如：

UIButton *firstButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 

//add firstButton to some view~ 
//.... 

firstButton.transform = CGAffineTransformIdentity; 
[UIView animateWithDuration:0.5 animations:^(void) { 
    firstButton.transform = CGAffineTransformMakeTranslation(0,10); 
} completion:^(BOOL finished){ 
    show your view controller~ 
}];

感謝@IPaPa但我的按鈕「自動動畫」。當我運行我的應用程序時，它會自動移動10px。我錯在哪裏？ UIImage * normalImage = [UIImage imageNamed：@「FirstImage」]; UIButton * firstButton = [UIButton buttonWithType：UIButtonTypeRoundedRect]; firstButton.frame = CGRectMake（31，194，normalImage.size.width，normalImage.size.height）; [firstButton setImage：normalImage forState：UIControlStateNormal]; [self.view addSubview：firstButton]; – TCvetkovic 2011-12-21 11:12:45

firstButton.transform = CGAffineTransformIdentity; [UIView animateWithDuration：0.5動畫：^（void）{ firstButton.transform = CGAffineTransformMakeTranslation（0,10）; }完成：^（布爾完成）{ //顯示您的視圖控制器〜 }]; – TCvetkovic 2011-12-21 11:17:03

是否將動畫代碼放在按鈕TouchUpInside回調中？ [UIView animation .....]之後，動畫會立即運行 – IPaPa 2011-12-21 18:41:23

[UIView animateWithDuration:0.5 animations:^{ 
    button.frame = CGRectMake:(button.frame.origin.x, button.frame.origin.y + 10.0f, button.frame.size.width, button.frame.size.height); 
}];

你可以把beginAnimations和commitAnimations塊之間的轉換（復位），縮放和rotatations在那裏你可以指定AnimationRepeatCount，AnimationCurve等

[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDelay:0.5]; 
[UIView setAnimationDuration:1]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; 

[UIView setAnimationRepeatAutoreverses:YES]; 
[UIView setAnimationRepeatCount:2]; 
..........................//etc. 

firstButton.frame = CGRectMake(31, 194, normalImage.size.width, normalImage.size.height); 
[UIView commitAnimations];

但在iOS4的，後來是動畫鼓勵執行

animateWithDuration：delay：options：animations：compeletion和類似的方法，invlove塊是ve強大。有關塊動畫的更多信息，請參考蘋果文檔
