IOS:UI系列之UISCROLLVIEW和UIPAGECONTROL

不平时间,又是一天,就这么忙坚苦碌的一天一天的过着, 不过辛亏,不是庸庸碌碌的,也好不轻巧小有所成,劳有所获吧,嘿嘿!

 

  好了,到了总括的年华啦, 下边就为我们轻便讲授下自个儿明天求学的剧情呢,希望对各位都负有帮衬吗,同一时候也是对团结的一种激情,最后促成共赢呢 嘿嘿!

 

  首先,在教授时间我们先轻易描述了UIScrollView, 它是一个轮转视图,传承于UIView,他一贯不团结的发轫化方法,所以要用到父类的创始方法上面就为大家轻便表明下其创建进程哈:

 

 

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];

    scrollView.backgroundColor = [UIColor redColor];

    //设置剧情页的分寸,内容的尺寸必须比frame大,技能够滚动

    //假若不安装剧情页的高低,暗许和frame大小同样

    [scrollView setContentSize:CGSizeMake(320, 568 * 3)];

    

    //设置滚动条是或不是可知

    //水平滚动条

    scrollView.showsHorizontalScrollIndicator = YES;

    //竖直滚动条

    scrollView.showsVerticalScrollIndicator = YES;

    //设置剧情页的偏移量, 暗许内容页从(0, 0)点起来

    scrollView.contentOffset = CGPointMake(0, 0);

    //设置整页滑动

    scrollView.pagingEnabled = NO;

    //设置边界是或不是回弹

    scrollView.bounces = YES;

    //滚动到顶端

    scrollView.scrollsToTop = YES;

    //设置是还是不是滚动

    scrollView.scrollEnabled = YES;

    //设置边界是或不是回弹,唯有在content的宽度只怕中度 小于 frame的宽窄可能高度,才有效

    scrollView.alwaysBounceVertical = YES;

    scrollView.alwaysBounceHorizontal = YES;

    

    //缩放, 缩放必须结合着代理(delegate)本领一蹴而就, 钦命scrollView上哪个视图进行缩放

    //设置当前的缩放比例, 默感觉1.0

    scrollView.zoomScale = 1.0;

    //设置最大缩放比例

    scrollView.maximumZoomScale = 2.0;

    //设置最小缩放比例

    scrollView.minimumZoomScale = 0.5;

    

    //设置delegate

    scrollView.delegate = self;

    

    [self.view addSubview:scrollView];

    [scrollView release];

    

    imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image"]];

    imageView.frame = CGRectMake(0, 0, 320, 568 * 3);

    [scrollView addSubview:imageView];

    [imageView release];

 

其间delegate代理的常用方法如下:

 

 

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

 

//当滚动scrollView时调用

- (void)scrollViewDidScroll:(UIScrollView *)scrollView

{

    NSLog(@"%s", __FUNCTION__);

}

 

//当发生了缩放的时候调用

- (void)scrollViewDidZoom:(UIScrollView *)scrollView

{

    NSLog(@"%s", __FUNCTION__);

}

 

//对ScrollView中的哪个视图缩放

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView

{

    return imageView;

}

//将要开头拖拽的时候调用

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView

{

    NSLog(@"%s", __FUNCTION__);

}

 

//将在截止拖拽的时候调用

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset

{

    NSLog(@"%s", __FUNCTION__);

}

 

//已经实现拖拽的时候调用

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate

{

    NSLog(@"%s", __FUNCTION__);

}

 

备感UIScrollView是为接下去所讲的做了一个铺垫,以便于达成之后图片页码的切换和滚动

 

在后来我们又讲了UIPageControl

 

UIPageControl:页码调节器,承继与UIControl

 

他和UIScrollView同样,也尚未和睦的起首化方法,同样要运用本人父类的点子,其切实创造方法如下所示

 

 

- (void)viewDidLoad

{

    [super viewDidLoad];

    //UIPageControl:页码调控器, 承袭于UIControl

    UIPageControl *pageControl = [[UIPageControl alloc] init];

    pageControl.frame = CGRectMake(0, 100, 320, 30);

    pageControl.backgroundColor = [UIColor blackColor];

    pageControl.numberOfPages = 10;

    //设置未当选的水彩

    pageControl.pageIndicatorTintColor = [UIColor yellowColor];

    //设置已入选的水彩

    pageControl.currentPageIndicatorTintColor = [UIColor blueColor];

    //设置独有一页时掩盖

    pageControl.hidesForSinglePage = NO;

    //关联方法

    [pageControl addTarget:self action:@selector(changePage:) forControlEvents:UIControlEventValueChanged];

    [self.view addSubview:pageControl];

    [pageControl release];

}

 

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

 

- (void)changePage:(UIPageControl *)pageControl

{

    //页码是从零初始的

    NSLog(@"%d", pageControl.currentPage 1);

}

 

下边我们来因而一个练兵来更是对那些空间作进一步的问询:

 

经过页面的滚动和页码的切换成调用方法进而使效果与利益类似于大家看电子书同样翻页跳转, 下边作者就来附上代码供大家参谋:

 

 

- (void)changePage:(UIPageControl *)pageControl

{

    if (pageControl.currentPage == 0) {

        [scrollView1 setContentOffset:CGPointMake(0, 0) animated:YES];

    } else if (pageControl.currentPage == 1) {

        [scrollView1 setContentOffset:CGPointMake(320, 0) animated:YES];

    } else if (pageControl.currentPage == 2) {

        [scrollView1 setContentOffset:CGPointMake(320 * 2, 0) animated:YES];

    }

}

 

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView

{

    pageControl1.currentPage = scrollView.contentOffset.x / 320;

}

 

- (void)close:(UIButton *)button1

{

    //尽管子视图的父视图被移除,那么这些子视图也会被移除

    [button removeFromSuperview];

    [scrollView1 removeFromSuperview];

    [pageControl1 removeFromSuperview];

}

转眼间,又是一天,就这么忙艰难碌的一天一天的过着, 可是幸好,不是毫无作为的,也总算小有所成,劳有所获...

2.创建UIScrollView

 

@implementation ViewController

- (UIScrollView *)scrollView

{    if (_scrollView == nil) {

_scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(10, 20, 300, 130)];

_scrollView.backgroundColor = [UIColor redColor];

[self.view addSubview:_scrollView];

_scrollView.bounces = NO;// 撤销弹簧效果

_scrollView.showsHorizontalScrollIndicator = NO;// 撤消水平滚动条

_scrollView.showsVerticalScrollIndicator = NO;// 撤废水平滚动条

_scrollView.pagingEnabled = YES;// 要分页

_scrollView.contentSize = CGSizeMake(kImageCount * _scrollView.bounds.size.width, 0);// contentSize

_scrollView.delegate = self;// 设置代理

}  return _scrollView; }

#import "ViewController.h"

- (void)viewDidLoad {

3.创建UIPageControl

 

[super viewDidLoad];

- (UIPageControl *)pageControl

{   if (_pageControl == nil) {

_pageControl = [[UIPageControl alloc] init];// 分页控件

_pageControl.numberOfPages = kImageCount;// 总页数

// 控件尺寸

CGSize size = [_pageControl sizeForNumberOfPages:kImageCount];

_pageControl.bounds = CGRectMake(0, 0, size.width, size.height);

_pageControl.center = CGPointMake(self.view.center.x, 130);

_pageControl.pageIndicatorTintColor = [UIColor redColor];

_pageControl.currentPageIndicatorTintColor = [UIColor blackColor];

[self.view addSubview:_pageControl];

@interface ViewController ()<UIScrollViewDelegate>

//创制开头化滑动视图

 加多监听方法

 

//[UIScreen mainScreen].bounds满含了荧屏的尺码

/** 在OC中,绝大非常多"控件",都得以监听UIControlEventValueChanged事件,button除此之外" */

#define  screenWidth  [UIScreen  mainScreen].bounds.size.width

self.scrollView=[[UIScrollView alloc]initWithFrame:[UIScreen mainScreen].bounds];

[_pageControl addTarget:self action:@selector(pageChanged:) forControlEvents:UIControlEventValueChanged];

}  return _pageControl;  }

#define  screenHeight  [UIScreen  mainScreen].bounds.size.height

for (NSInteger i=0; i<6; i ) {

分页控件的监听方法

 

//依照i循环创造UIImageView,再增加到滑动视图scrollView上边

- (void)pageChanged:(UIPageControl *)page

{   NSLog(@"%d", page.currentPage);

// 依照页数,调度滚动视图中的图片位置 contentOffset

CGFloat x = page.currentPage * self.scrollView.bounds.size.width;

//设置contentoffset

[self.scrollView setContentOffset:CGPointMake(x, 0) animated:YES];  }

/*

UIImageView *imageView=[[UIImageView alloc]initWithFrame:CGRectMake(i*ScreenWidth, 0, ScreenWidth, ScreenHeight)];

视图加载成功调用,平时用来安装数据

 UIPageControl   numOfPages currentPage

NSString *imageName=nil;

- (void)viewDidLoad

 */

if (i==5) {

{  [super viewDidLoad];

 

imageName=@"1.jpg";

// 增多图片

 

}else{

for (int i = 0; i < kImageCount; i ) {

NSString *imageName = [NSString stringWithFormat:@"img_d", i 1];

UIImage *image = [UIImage imageNamed:imageName];

UIImageView *imageView = [[UIImageView alloc] initWithFrame:self.scrollView.bounds];

imageView.image = image;

[self.scrollView addSubview:imageView];  }

 

imageName=[NSString stringWithFormat:@"%ld.jpg",i 1];

// 计算imageView的位置

 

}

[self.scrollView.subviews enumerateObjectsUsingBlock:^(UIImageView *imageView, NSUInteger idx, BOOL *stop) {

// 调整x => origin => frame

CGRect frame = imageView.frame;

frame.origin.x = idx * frame.size.width;

imageView.frame = frame;

}];

//    NSLog(@"%@", self.scrollView.subviews);

self.pageControl.currentPage = 0;  // 分页初步页数为0

[self startTimer];  }    // 运行石英钟

- (void)startTimer

{  self.timer = [NSTimer timerWithTimeInterval:2.0 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES];

// 增加到运维循环

[[NSRunLoop currentRunLoop] addTimer:self.timer forMode:NSRunLoopCommonModes];  }

- (void)updateTimer

{    // 页号产生变化

// (当前的页数 1) % 总页数

int page = (self.pageControl.currentPage 1) % kImageCount;

self.pageControl.currentPage = page;

NSLog(@"%d", self.pageControl.currentPage);

// 调用监听方法,让滚动视图滚动

[self pageChanged:self.pageControl]; }

 

//        NSString *imageName=[NSString stringWithFormat:@"%ld.jpg",i 1];

#pragma mark - ScrollView的代理方法

 

//加载响应图片

// 滚动视图停下来,修改页面控件的小点(页数)

 

UIImage *image=[UIImage imageNamed:imageName];

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView

{  // 停下来的眼下页数

NSLog(@"%@", NSStringFromCGPoint(scrollView.contentOffset));

// 总括页数

int page = scrollView.contentOffset.x / scrollView.bounds.size.width;

self.pageControl.currentPage = page; }

 

//设置图片

修改时钟所在的运行循环的格局后,抓不住图片

//滑动视图UIScrollView,自带了可滑动功能

imageView.image=image;

消除措施:抓住图片时,截至机械钟,送售后,开启时钟

@property(nonatomic,strong)UIScrollView  *scrollView;

//将imageView增加到滑动视图上面

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView

{  NSLog(@"%s", __func__);

// 停止石英钟,停止今后就不可能再利用,如若要启用石英钟,必要再行实例化

[self.timer invalidate];  }

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate

{  NSLog(@"%s", __func__);

[self startTimer];  }

//页面提醒器

[self.scrollView addSubview:imageView];
