如何使用NSTimer添加像動畫的UIImages？

Question

我想使用NSTimer將UIImage數組添加到UIImageView。這樣它就會像動畫一樣。如何在iOS中做到這一點？ 在此先感謝。

有一個非常簡單的方法來做到這一點。

// create the view that will execute our animation 
UIImageView* campFireView = [[UIImageView alloc] initWithFrame:self.view.frame]; 

// load all the frames of our animation 
campFireView.animationImages = [NSArray arrayWithObjects:  
          [UIImage imageNamed:@"campFire01.gif"], 
          [UIImage imageNamed:@"campFire02.gif"], 
          [UIImage imageNamed:@"campFire03.gif"], 
          [UIImage imageNamed:@"campFire04.gif"], 
          [UIImage imageNamed:@"campFire05.gif"], 
          [UIImage imageNamed:@"campFire06.gif"], 
          [UIImage imageNamed:@"campFire07.gif"], 
          [UIImage imageNamed:@"campFire08.gif"], 
          [UIImage imageNamed:@"campFire09.gif"], 
          [UIImage imageNamed:@"campFire10.gif"], 
          [UIImage imageNamed:@"campFire11.gif"], 
          [UIImage imageNamed:@"campFire12.gif"], 
          [UIImage imageNamed:@"campFire13.gif"], 
          [UIImage imageNamed:@"campFire14.gif"], 
          [UIImage imageNamed:@"campFire15.gif"], 
          [UIImage imageNamed:@"campFire16.gif"], 
          [UIImage imageNamed:@"campFire17.gif"], nil]; 

// all frames will execute in 1.75 seconds 
campFireView.animationDuration = 1.75; 
// repeat the annimation forever 
campFireView.animationRepeatCount = 0; 
// start animating 
[campFireView startAnimating]; 
// add the animation view to the main window 
[self.view addSubview:campFireView];
