左右滑动加点击跳转

类似于答题功能，可以实现左右滑动到下一页面，或者能过点击跳转到下一题

直接贴代码

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    self.title = @"左右滑动+Btn滑动";

    [selfcreatSubview];

}

 

//创建子view

- (void)creatSubview

{

 

    _mArray = [NSMutableArraynew];

    NSInteger heigth = self.view.frame.size.height;

    NSInteger width = self.view.frame.size.width;

    _scrollview = [[UIScrollViewalloc] initWithFrame:CGRectMake(0, 0, width, heigth)];

    _scrollview.backgroundColor = [UIColorwhiteColor];

    _scrollview.pagingEnabled = YES;

    _scrollview.scrollEnabled=YES;

    _scrollview.showsHorizontalScrollIndicator=NO;

    _scrollview.showsVerticalScrollIndicator=NO;

    _scrollview.delegate=self;

    [self.viewaddSubview:_scrollview];

    

    _array=[NSArrayarrayWithObjects:[UIColororangeColor],[UIColorpurpleColor], [UIColorwhiteColor],[UIColorredColor],[UIColorgreenColor],[UIColorgrayColor],nil];

    

    UIView * view =[[UIViewalloc] initWithFrame:CGRectMake(_pageNumber*_scrollview.frame.size.width,0,_scrollview.frame.size.width,_scrollview.frame.size.height)];

    [_scrollviewaddSubview:view];

 

    _scrollview.contentSize=CGSizeMake(width * 7, 0);

    

    _btn = [UIButtonbuttonWithType:(UIButtonTypeCustom)];

    _btn.frame = CGRectMake(width / 3, heigth / 3, width / 3, 30);

    _btn.backgroundColor = [UIColorblueColor];

    [_btnsetTitle:@"0"forState:(UIControlStateNormal)];

    [_btnaddTarget:selfaction:@selector(btnAction:) forControlEvents:(UIControlEventTouchUpInside)];

    [self.viewaddSubview:_btn];

    

}

 

//button事件

- (void)btnAction:(UIButton * )btn

{

    if (_pageNumber != _array.count - 1) {

        _pageNumber++;

 

    }else{

    

        NSLog(@"The last one");

    }

    //动态创建view

    [selfcreatView:_pageNumber];

    

//    NSLog(@"click");

    [btn setTitle:[NSStringstringWithFormat:@"%ld",(long)_pageNumber] forState:(UIControlStateNormal)];

    CGFloat x = _pageNumber * self.scrollview.frame.size.width;

    _scrollview.contentOffset = CGPointMake(x,0);

}

 

#pragma mark - scrollView的代理方法

 -(void)scrollViewDidScroll:(UIScrollView *)scrollView

 {

     

       //计算相应地页(滚动视图可以滚动的总宽度/单个滚动视图的宽度=滚动视图的页数)

         NSInteger currentPage = (int)(scrollView.contentOffset.x) / (int)(self.view.frame.size.width);

     

     _pageNumber = currentPage;//将上述的滚动视图页数重新赋给当前视图页数,进行分页

    

    [selfcreatView:_pageNumber];

   

     

     [_btnsetTitle:[NSStringstringWithFormat:@"%ld",_pageNumber] forState:(UIControlStateNormal)];

     

//     NSLog(@"%ld",_pageNumber);

  

     

}

 

//动态创建view

- (void)creatView:(NSInteger)number

{

     BOOL isbool = [_mArraycontainsObject: [NSStringstringWithFormat:@"%ld",(long)number]];

    if (isbool == 0) {

        [_mArrayaddObject:[NSStringstringWithFormat:@"%ld",(long)number]];

        UIView * view =[[UIViewalloc] initWithFrame:CGRectMake(number*_scrollview.frame.size.width,0,_scrollview.frame.size.width,_scrollview.frame.size.height)];

        NSLog(@"creatSubv%@",_mArray);

        [_scrollviewaddSubview:view];

    }else{

    

        NSLog(@"Digital already exists");

    }
