先上效果图:

首先初始化:

- (void)viewDidLoad

{

    //加入最后一张图 用于循环

    int length = 4;

    NSMutableArray *tempArray = [NSMutableArray array];

    for (int i = 0 ; i < length; i++)

    {

        NSString* str = [NSString stringWithFormat:@"title%d",i];

        [tempArray addObject:str];

    }

    NSMutableArray *itemArray = [NSMutableArray arrayWithCapacity:length+2];

    if (length > 1)

    {

        NSString *str1 = [tempArray objectAtIndex:length-1];  //title3

        SGFocusImageItem *item = [[SGFocusImageItem alloc] initWithTitle:str1 tag:-1];

        [itemArray addObject:item];

    }

    for (int i = 0; i < length; i++)

    {

        NSString *str2 = [tempArray objectAtIndex:i];

        SGFocusImageItem *item = [[SGFocusImageItem alloc] initWithTitle:str2 tag:i];

        [itemArray addObject:item];

    }

    //加入第一张图 用于循环

    if (length >1)

    {

        NSString *str3 = [tempArray objectAtIndex:0];

        SGFocusImageItem *item = [[SGFocusImageItem alloc] initWithTitle:str3 tag:length]; //title0

        [itemArray addObject:item];

    }

    ViewFrame *bannerView = [[ViewFrame alloc] initWithFrame:CGRectMake(0, 0, 320, 105) imageItems:itemArray isAuto:NO];

    [self.view addSubview:bannerView];

}

SGFocusImageItem仅仅有一个Title和tag:

@interface SGFocusImageItem : NSObject

@property (nonatomic, strong)  NSString     *title;

@property (nonatomic, assign)  NSInteger     tag;

- (id)initWithTitle:(NSString *)title tag:(NSInteger)tag;

@end

主要是ViewFrame:

#define ITEM_WIDTH 320.0

@interface ViewFrame : UIView<UIScrollViewDelegate>

@property(nonatomic,strong)NSMutableArray* imageItems;

@property(nonatomic,strong)UIScrollView* scrollView;

- (id)initWithFrame:(CGRect)frame imageItems:(NSArray *)items isAuto:(BOOL)isAuto;

@end

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{

    float targetX = _scrollView.contentOffset.x;

    NSLog(@"=====scrollViewdidscroll targetX=%f",targetX);

  <strong>  if ([_imageItems count] >= 3) {

        //假设超过最后一张图，则又一次设置setContentOffset

        if (targetX >= ITEM_WIDTH * ([_imageItems count]-1)) {

            targetX = ITEM_WIDTH;

            [_scrollView setContentOffset:CGPointMake(targetX, 0) animated:NO];

        }

        else if(targetX <= 0){

            targetX = ITEM_WIDTH * ([_imageItems count] - 2);

            [_scrollView setContentOffset:CGPointMake(targetX, 0) animated:NO];

        }

    }</strong>

}

- (id)initWithFrame:(CGRect)frame

{

    self = [super initWithFrame:frame];

    if (self) {

        // Initialization code

    }

    return self;

}

-(void)setupViews{

    _scrollView = [[UIScrollView alloc] initWithFrame:self.bounds];

    _scrollView.scrollsToTop = NO;

    CGSize size = CGSizeMake(320, 0);

    _scrollView.showsHorizontalScrollIndicator = NO;

    _scrollView.pagingEnabled = YES;

    _scrollView.delegate = self;

    _scrollView.contentSize = CGSizeMake(_scrollView.frame.size.width * _imageItems.count,

                                         _scrollView.frame.size.height);

    [self addSubview:_scrollView];

    for (int i = 0; i < _imageItems.count; i++) {

        SGFocusImageItem* item = [_imageItems objectAtIndex:i];

        int x = i * _scrollView.frame.size.width;

        int width = _scrollView.frame.size.width;

        int height = _scrollView.frame.size.height;

        UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(x, 0, width, height)];

        if (i == 0) {

            imageView.backgroundColor = [UIColor brownColor];

        } else if(i == 1) {

            imageView.backgroundColor = [UIColor orangeColor];

        } else if(i == 2) {

            imageView.backgroundColor = [UIColor blueColor];

        }else if(i == 3){

            imageView.backgroundColor = [UIColor redColor];

        }else if(i == 4){

            imageView.backgroundColor = [UIColor greenColor];

        }else if(i == 5) {

            imageView.backgroundColor = [UIColor lightGrayColor];

        }

        UITextField* field = [[UITextField alloc] initWithFrame:CGRectMake(x+160, 30, 50, 50)];

        field.text =  item.title;

        //   NSLog(@"====kkkkk title=%@",item.title);

        field.textAlignment = UITextAlignmentCenter;

        field.font = [UIFont systemFontOfSize:18];

        [_scrollView addSubview:imageView];

        [_scrollView addSubview:field];

    }

}

- (id)initWithFrame:(CGRect)frame imageItems:(NSArray *)items isAuto:(BOOL)isAuto{

    self = [super initWithFrame:frame];

    if (self) {

        _imageItems = [NSMutableArray arrayWithArray:items];

        [self setupViews];

    }

    return self;

}
