Demo code:

// 1. From internet
[scrollView addSubview:({

    LCBannerView *bannerView = [LCBannerView bannerViewWithFrame:CGRectMake(0, 300.0f, [UIScreen mainScreen].bounds.size.width, 200.0f)
                                                        delegate:self
                                                       imageURLs:URLs
                                            placeholderImageName:nil
                                                    timeInterval:2.0f
                                   currentPageIndicatorTintColor:[UIColor redColor]
                                          pageIndicatorTintColor:[UIColor whiteColor]];
    bannerView.pageDistance = 20.0f;
    bannerView;
})];

// 2. From local
// If you using images from local, you should let images named: `banner_01@2x.png`, `banner_02@2x.png`...
// Than, you just give me a image named: `banner`. 😜
[scrollView addSubview:({

    LCBannerView *bannerView = [[LCBannerView alloc] initWithFrame:CGRectMake(0, 20.0f, [UIScreen mainScreen].bounds.size.width, 200.0f)
                                                          delegate:self
                                                         imageName:@"banner"
                                                             count:3
                                                      timeInterval:3.0f
                                     currentPageIndicatorTintColor:[UIColor orangeColor]
                                            pageIndicatorTintColor:[UIColor whiteColor]];
    bannerView;
})];

Advise for run demo:

You should comment out one of the Block code or Delegate code in demo code, it will help you read code more clearly.

See below two points for more information.

Block: (@optional)

@property (nonatomic, copy) LCBannerViewDidClickedImageIndexBlock didClickedImageIndexBlock;

@property (nonatomic, copy) LCBannerViewDidScrollToIndexBlock didScrollToIndexBlock;

For example:

bannerView.didClickedImageIndexBlock = ^(LCBannerView *bannerView, NSInteger index) {
    
    NSLog(@"Block: Clicked image in %p at index: %d", bannerView, (int)index);
};

bannerView.didScrollToIndexBlock = ^(LCBannerView *bannerView, NSInteger index) {
    
    NSLog(@"Block: Scrolled in %p to index: %d", bannerView, (int)index);
};

Delegate: (@optional)

- (void)bannerView:(LCBannerView *)bannerView didClickedImageIndex:(NSInteger)index;

- (void)bannerView:(LCBannerView *)bannerView didScrollToIndex:(NSInteger)index;

For example:

- (void)bannerView:(LCBannerView *)bannerView didClickedImageIndex:(NSInteger)index {
    
    NSLog(@"Delegate: Clicked image in %p at index: %d", bannerView, (int)index);
}

- (void)bannerView:(LCBannerView *)bannerView didScrollToIndex:(NSInteger)index {
    
    NSLog(@"Delegate: Scrolled in %p to index: %d", bannerView, (int)index);
}

Custom parameters:

// Distance to bottom of pageControl. Default is `10.0f`.
@property (nonatomic, assign) CGFloat   pageDistance;

// Not allow scrolling. Default `No`, allow scrolling.
@property (nonatomic, assign) BOOL      notScrolling;

ChangeLog

V 2.1.1

Hide pageControl support:

// Hide or show pageControl. Default is `NO`, show pageControl.
@property (nonatomic, assign) BOOL hidePageControl;

V 2.1.0

Implementation requirement: Issue 6 by skyboy1342.

Now you could get the clicked image's index and the index scroll to, with Block or Delegate, see Usage.
Calculation: didScrollToIndex method won't be called to index 0 when you add bannerView to superView, because it hadn't scroll at all, and in fact you know index is 0 now because you do this.

V 2.0.0 (⚠️ Important)

Fix Issue 5, thx MVakas!

Modify some of the properties' name and methods' name:

// Properties' name.
@property (nonatomic, assign) CGFloat timerInterval;
->
@property (nonatomic, assign) CGFloat timeInterval;

@property (nonatomic, copy  ) NSString  *placeholderImage;
->
@property (nonatomic, copy  ) NSString  *placeholderImageName;

// All methods' name.
timerInterval -> timeInterval
placeholderImage -> placeholderImageName

V 1.2.5

Update README and some documents.

V 1.2.2

Update CocoaPods source URL.

V 1.2.0

You could custom the images should scrolling now, thx ac1dpax. For example:

LCBannerView *bannerView = [[LCBannerView alloc] initWithFrame:CGRectMake(0, 20.0f, [UIScreen mainScreen].bounds.size.width, 200.0f)
                                                      delegate:self
                                                     imageName:@"banner"
                                                         count:3
                                                 timerInterval:3.0f
                                 currentPageIndicatorTintColor:[UIColor orangeColor]
                                        pageIndicatorTintColor:[UIColor whiteColor]];
bannerView.pageDistance = 20.0f;
bannerView.notScrolling = YES; // THIS LINE ⬅️
bannerView;

V 1.1.0

You could custom page control bottom distance now. For example:
```
// ...
bannerView.pageDistance = 20.0f;
```

V 1.0.0
