PRSlideView 0.3.1

General

Slide view with gracefully written UIKit-like methods, delegate and data source protocol.

Note: Auto layout not supported due to the special behaviours of UIScrollView. Please use autoresizing mask instead or wrap it with a container view.

Features

  • Horizontal or vertical scrolling
  • Infinite scrolling
  • Page control (horizontal mode only)

Installation

Usage

Create a Slide View

PRSlideView *slideView = [[PRSlideView alloc] initWithFrame:self.view.bounds];
slideView.delegate = self;
slideView.dataSource = self;
slideView.direction = PRSlideViewDirectionHorizontal; // horizontal by default
slideView.infiniteScrollingEnabled = YES; // disabled by default
slideView.showsPageControl = YES; // enabled by default
[slideView registerClass:PRAlbumPage.class
  forPageReuseIdentifier:NSStringFromClass(PRAlbumPage.class)];
slideView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                              UIViewAutoresizingFlexibleHeight);
self.slideView = slideView;
[self.view addSubview:slideView];

Create a Slide View Page Subclass

#import "PRSlideViewPage.h"

@interface PRAlbumPage : PRSlideViewPage

@property (nonatomic, weak) UIImageView *coverImageView;

@end

#import "PRAlbumPage.h"

@implementation PRAlbumPage

- (instancetype)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        UIImageView *coverImageView = [[UIImageView alloc] initWithFrame:self.bounds];
        coverImageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                                           UIViewAutoresizingFlexibleHeight);
        coverImageView.contentMode = UIViewContentModeScaleAspectFit;
        self.coverImageView = coverImageView;
        [self addSubview:coverImageView];
    }
    return self;
}

Use Data Source

#pragma mark - PRSlideViewDataSource

- (NSInteger)numberOfPagesInSlideView:(PRSlideView *)slideView
{
    return self.albumData.count;
}

- (PRSlideViewPage *)slideView:(PRSlideView *)slideView pageAtIndex:(NSInteger)index
{
    PRAlbumPage *page = [slideView dequeueReusablePageWithIdentifier:NSStringFromClass(PRAlbumPage.class)
                                                            forIndex:index];

    NSString *imageName = [self.albumData[index] stringByAppendingPathExtension:@"jpg"];
    page.coverImageView.image = [UIImage imageNamed:imageName];

    return page;
}

Use Delegate

#pragma mark - PRSlideViewDelegate

- (void)slideView:(PRSlideView *)slideView didScrollToPageAtIndex:(NSInteger)index
{
    self.titleLabel.text = self.albumData[index];
}

- (void)slideView:(PRSlideView *)slideView didClickPageAtIndex:(NSInteger)index
{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"You clicked an album"
                                                    message:self.albumData[index]
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
}
