ios - 从数组中加载图像并一次显示一个

Question

我想在一个 ImageView 中显示图像，当调用 IBAction 时它显示下一张图像。到目前为止，这是我的代码

- (void)viewDidLoad
{
[super viewDidLoad];
//init array with images what you have
   images = [[NSArray alloc] initWithObjects:@"IMG_2605.JPG",@"IMG_2627.JPG",@"IMG_2597.JPG",@"IMG_2613.JPG",@"IMG_2596.JPG  ",nil];
indexImage = 0;

}

-(IBAction)button1:(id)sender {
NSString *imageName = [images objectAtIndex:indexImage];
self.image1.image = [UIImage imageNamed:imageName];
    self.image1.image = [images objectAtIndex:indexImage];
indexImage++;

NSLog(@"B = 1");
}

Answer 1

您需要获取实际图像，而不是图像的文件名。如果这些图像在您的包中，您可以使用方法 imageNamed: 来获取图像:

NSString *imageName = [images objectAtIndex:indexImage];
self.image1.image = [UIImage imageNamed:imageName];
