2 个解决方案

Try this,

尝试这个，

First you declare

首先你宣布

NSInteger currentPosition;

put this code in viewDidLoad

将此代码放在viewDidLoad中

//initially give position as 1 for first image view
currentPosition = 1;
NSLog(@"Start");
timer = [NSTimer scheduledTimerWithTimeInterval:5
                                         target:self
                                       selector:@selector(targetMethod:)
                                       userInfo:nil
                                        repeats:YES];

and, write this function

并且，写这个功能

-(void)targetMethod:(NSTimer *)timer
{
    if (currentPosition == 1) {
        firstImageView.image = [UIImage imageNamed:@"37240152-nature-desktop-wallpaper.jpg"];
        currentPosition = 2;
    }else if(currentPosition == 2){
        secondImageView.image = [UIImage imageNamed:@"37240152-nature-desktop-wallpaper.jpg"];
        currentPosition = 3;
    }else if(currentPosition == 3){
        thirdImageView.image = [UIImage imageNamed:@"37240152-nature-desktop-wallpaper.jpg"];
        currentPosition = 1;
    }
}

As I understand, you need something like Image Carousel,

据我所知，你需要像Image Carousel这样的东西，

t0
---
imageView1 = image1
imageView2 = image2
imageView3 = image3

t1
---
imageView1 = image3
imageView2 = image1
imageView3 = image2
...

If this is what you want, you can use a carousel with 3 images only and add a loop.

如果这是你想要的，你可以使用只有3张图像的旋转木马并添加一个循环。
