用法示例
Masonry自动布局
使用Masonry自动布局，请在设置布局之后调用该方法kj_useMasonry
- (void)setMasonry{ self.banner2 = [[KJBannerView alloc]init]; self.banner2.autoTime = 2; self.banner2.isZoom = YES; self.banner2.itemSpace = -10; self.banner2.itemWidth = 280; self.banner2.delegate = self; self.banner2.dataSource = self; self.banner2.imageType = KJBannerViewImageTypeMix; self.banner2.pageControl.pageType = PageControlStyleSizeDot; self.banner2.pageControl.displayType = KJPageControlDisplayTypeRight; self.banner2.pageControl.backgroundColor = [UIColor.blackColor colorWithAlphaComponent:0.5]; [self.backView addSubview:self.banner2]; [self.banner2 mas_makeConstraints:^(MASConstraintMaker *make) { make.top.left.right.bottom.mas_equalTo(0); }]; [self.banner2 kj_useMasonry]; self.banner2.imageDatas = self.temp; }
Xib布局
- (void)setXib{ self.banner.delegate = self; self.banner.pageControl.pageType = PageControlStyleRectangle; self.banner.pageControl.selectColor = UIColor.greenColor; self.banner.pageControl.dotwidth = 20; self.banner.pageControl.dotheight = 2; self.banner.pageControl.backgroundColor = [UIColor.blackColor colorWithAlphaComponent:0.5]; self.banner.pageControl.displayType = KJPageControlDisplayTypeLeft; self.banner.imageType = KJBannerViewImageTypeMix; self.banner.bannerScale = YES; self.banner.rollType = KJBannerViewRollDirectionTypeBottomToTop; self.banner.bannerContentMode = UIViewContentModeScaleAspectFill; self.banner.imageDatas = @[tu2,gif2,@"IMG_0139",@"tu3"]; [self.banner kj_makeScrollToIndex:1]; }
委托自定义控件
#pragma mark - KJBannerViewDataSource - (UIView*)kj_BannerView:(KJBannerView*)banner BannerViewCell:(KJBannerViewCell*)bannercell ImageDatas:(NSArray*)imageDatas Index:(NSInteger)index{ KJBannerModel *model = imageDatas[index]; CGRect rect = {0, 0, 100, 20}; UILabel *label = [[UILabel alloc]initWithFrame:rect]; if (index == 0) { label.text = @"定制不同的控件"; label.frame = CGRectMake(0, 0, bannercell.contentView.frame.size.width, 40); label.font = [UIFont boldSystemFontOfSize:35]; label.textColor = UIColor.greenColor; label.textAlignment = NSTextAlignmentCenter; } KJLoadImageView *imageView = [[KJLoadImageView alloc]initWithFrame:bannercell.contentView.bounds]; imageView.kj_isScale = YES; [imageView kj_setImageWithURLString:model.customImageUrl Placeholder:[UIImage imageNamed:@"tu3"]]; [imageView addSubview:label]; return imageView; }
继承方式自定义控件
- (void)setText{ self.banner3.showPageControl = NO; #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wdeprecated-declarations" self.banner3.itemClass = [KJCollectionViewCell class]; #pragma clang diagnostic pop self.banner3.rollType = KJBannerViewRollDirectionTypeBottomToTop; self.banner3.imageDatas = @[@"测试文本滚动",@"觉得好用请给我点个星",@"有什么问题也可以联系我",@"邮箱: ykj310@126.com"]; }
自定义Cell使用
- (void)setModel:(NSObject*)model{ self.label.text = (NSString*)model; }
