ios - iOS：UIImageView 幻灯片

Question

对于 iOS 应用程序，我希望 UIImageView 在幻灯片中包含多个图像。我还希望能够即时选择活动照片。是否有捷径可寻？（具体的代码会很好，但也可以提供一两个提示）。

谢谢！

Answer 1

为此，我制作了一个小型库，非常灵活，有很多选项：https ://github.com/kirualex/KASlideShow

一个简单的幻灯片声明如下所示：

_slideshow.delegate = self;
[_slideshow setDelay:1]; // Delay between transitions
[_slideshow setTransitionDuration:.5]; // Transition duration
[_slideshow setTransitionType:KASlideShowTransitionFade]; // Choose a transition type (fade or slide)
[_slideshow setImagesContentMode:UIViewContentModeScaleAspectFill]; // Choose a content mode for images to display
[_slideshow addImagesFromResources:@[@"test_1.jpeg",@"test_2.jpeg",@"test_3.jpeg"]]; // Add images from resources
[_slideshow addGesture:KASlideShowGestureTap]; // Gesture to go previous/next directly on the image

- (void)awakeFromNib {
    timer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(updatePhoto) userInfo:nil repeats:YES];
    count = 0;
}
// this creates a loop every 0.5 secs.
// then set up your image changes.

-(void)updatePhoto{
    count = count + 1;
    [self updateImage];
}

-(void)updateImage{
    if (count == 1){
        mainImage.image = [UIImage imageNamed:@\"img2.jpg\"];
    }
    if (count == 2){
        mainImage.image = [UIImage imageNamed:@\"img4.jpg\"];
    }
    if (count == 3){
        mainImage.image = [UIImage imageNamed:@\"img3.jpg\"];
    }
    if (count == 4){
        mainImage.image = [UIImage imageNamed:@\"img3.jpg\"];
    }
    else{
        mainImage.image = [UIImage imageNamed:@\"img1.jpg\"];
    }

}
