Question

我创建了一个nsmutableArray，我为它添加了一个图像。我也创建了一个imageView，我想显示数组中的图像，我试图使用animationImages但我没有发生任何事情，我该如何解决？这是我的代码：

    //Numbers images
    UIImage *numberZero = [UIImage imageNamed:@"numberZero.png"];
    UIImage *numberOne = [UIImage imageNamed:@"numberOne.png"];
    UIImage *numberTwo = [UIImage imageNamed:@"numberTwo.png"];
    UIImage *numberThree = [UIImage imageNamed:@"numberThree.png"];
    UIImage *numberFour = [UIImage imageNamed:@"numberFour.png"];
    UIImage *numberFive = [UIImage imageNamed:@"numberFive.png"];
    UIImage *numberSix = [UIImage imageNamed:@"numberSix.png"];
    UIImage *numberSeven = [UIImage imageNamed:@"numberSeven.png"];
    UIImage *numberEight = [UIImage imageNamed:@"numberEight.png"];
    UIImage *numberNine = [UIImage imageNamed:@"numberNine.png"];

    //add numbers uiimage to numbersArray
    numbersArray = [NSMutableArray arrayWithObjects:numberZero, numberOne, numberTwo, numberThree, numberFour, numberFive, numberSix, numberSeven, numberEight, numberNine, nil];


    imgview1 = [[UIImageView alloc] init];
    imgview1.animationImages = numbersArray;
    imgview1.animationDuration = 2;
    imgview1.animationRepeatCount=0;
    [imgview1 startAnimating];
    [imgview1 stopAnimating];

谢谢！

您需要实际添加imgview1以显示它。如果在Interface Builder中创建了imgview1，则无需分配。您也可以在启动动画后立即停止动画。

//If created in IB comment out the next line
imgview1 = [[UIImageView alloc] init];
imgview1.animationImages = numbersArray;
imgview1.animationDuration = 2;
imgview1.animationRepeatCount=0;

//If not created in IB then add this to a view e.g:
[self.view addSubview:imgview1]; 

[imgview1 startAnimating];
//[imgview1 stopAnimating]; this is too soon to stop animating

我认为通过“没有发生”你的意思是你看到第一张图片，但序列并没有超越它。

这可能是因为你stopAnimating太快了：它甚至没有机会开始！

Answer 3

我解决了这个问题，我想这个问题是因为我没有在我的imgview中使用带帧的init。这是最终的代码：

    UIImageView *imgview1 = [[UIImageView alloc] initWithFrame:CGRectMake(40, 90, 240, 240)];
    imgview1.animationImages = numbersArray;
    imgview1.animationDuration = 2;
    imgview1.animationRepeatCount=1;
    [imgview1 startAnimating];
    [self.view addSubview:imgview1];
