This UIView Subclass is used to present Images loaded from the Web and is inspired from foursquare's Image Slideshow. The used will be downloaded asynchronously. Former dependencies on SDWebImage have been removed.
This is what the ImagePager looks like when it's set up:
Implementing the ImagePager is fairly easy, just set it up in Interface Builder:
Optionally customize the PageControl's appearance:
- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
_imagePager.pageControl.currentPageIndicatorTintColor = [UIColor lightGrayColor];
_imagePager.pageControl.pageIndicatorTintColor = [UIColor blackColor];
_imagePager.pageControlCenter = CGPointMake(CGRectGetWidth(_imagePager.frame) / 2, CGRectGetHeight(_imagePager.frame) - 42);
}PageControl and ImageCounter can be hidden separately by setting imageCounterDisabled and imageCounterDisabled property. There is also a property hidePageControlForSinglePages.
Now implement it's DataSource and (optionally) Delegate methods:
- (NSArray *) arrayWithImages:(KIImagePager*)pager
{
return @[
@"https://raw.github.com/kimar/tapebooth/master/Screenshots/Screen1.png",
[UIImage imageNamed:@"MySuperImage1"],
@"https://raw.github.com/kimar/tapebooth/master/Screenshots/Screen2.png",
[UIImage imageNamed:@"MySuperImage2"],
@"https://raw.github.com/kimar/tapebooth/master/Screenshots/Screen3.png"
];
}As you can see, it's now perfectly ok to mix urlStrings as well as UIImages inside arrayWithImages DataSource method.
- (UIViewContentMode) contentModeForImage:(NSUInteger)image inPager:(KIImagePager*)pager
{
return UIViewContentModeScaleAspectFill;
}Optionally you might define a caption title which will be shown above the images using the captionForImageAtIndex DataSource method.
- (NSString *) captionForImageAtIndex:(NSUInteger)index inPager:(KIImagePager*)pager
{
return @[
@"First screenshot",
@"Another screenshot",
@"Last one! ;-)"
][index];
}If you'd like to get a SlideShow, just give it an interval for the time between those single slides:
_imagePager.slideshowTimeInterval = 1.5f;The MIT License (MIT)
