一.声明属性和代理
<UIScrollViewDelegate>
@property(nonatomic,strong)UISegmentedControl * segmentedControl;
@property(nonatomic,strong)UIScrollView *bgScroll;
@property(nonatomic,strong) UIView *bgView ;
@property(nonatomic,strong) UIView *bgView1 ;
@property(nonatomic,strong) UIView *bgView2;
二.实现
#pragma mark - content内容
- (void)creatContent{
NSArray *segmentedArray = [[NSArray alloc]initWithObjects:@"实时数据",@"数据总览",@"评估报告",nil];
//初始化UISegmentedControl
self.segmentedControl = [[UISegmentedControl alloc]initWithItems:segmentedArray];
self.segmentedControl.frame = CGRectMake(30, HEIGHT*0.12, WIDTH-60, 30);
self.segmentedControl.selectedSegmentIndex = 0;
self.segmentedControl.tintColor = [UIColor whiteColor];
NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,[UIFont fontWithName:@"Helvetica" size:16] ,NSFontAttributeName,nil];
[self.segmentedControl setTitleTextAttributes:dic forState:UIControlStateNormal];
NSDictionary *dic1 = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor blueColor],NSForegroundColorAttributeName,[UIFont fontWithName:@"Helvetica" size:16] ,NSFontAttributeName,nil];
[self.segmentedControl setTitleTextAttributes:dic1 forState:UIControlStateSelected];
[self.segmentedControl addTarget:self action:@selector(segmentedClick:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:self.segmentedControl];
}
- (void)segmentedClick:(UISegmentedControl *)sender{
NSInteger index = sender.selectedSegmentIndex;
switch (index) {
case 0:
{
self.bgScroll.contentOffset = CGPointMake(0, 0);
}
break;
case 1:
{
self.bgScroll.contentOffset = CGPointMake(WIDTH, 0);
}
break;
case 2:
{
self.bgScroll.contentOffset = CGPointMake(WIDTH * 2, 0);
}
break;
}
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
[UIView animateWithDuration:1 animations:^{
self.segmentedControl.selectedSegmentIndex = (scrollView.contentOffset.x + (WIDTH-20)*0.5)/(WIDTH-20);
}];
}
- (void)createBottomLayer{
self.bgScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(0, HEIGHT*0.12 + 30 + 15, WIDTH, HEIGHT*0.88 -45)];
self.bgScroll.pagingEnabled= YES;
self.bgScroll.delegate = self;
self.bgScroll.bounces = NO;
self.bgScroll.contentSize = CGSizeMake(WIDTH*3, 0);
[self.view addSubview:self.bgScroll];
self.bgView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT*0.88 - 45)];
self.bgView.backgroundColor = [UIColor clearColor];
[self.bgScroll addSubview:self.bgView];
self.bgView1 = [[UIView alloc]initWithFrame:CGRectMake(WIDTH, 0, WIDTH, HEIGHT*0.88 - 45)];
self.bgView1.backgroundColor = [UIColor yellowColor];
self.bgView1.alpha = 0.7;
[self.bgScroll addSubview:self.bgView1];
self.bgView2 = [[UIView alloc]initWithFrame:CGRectMake(WIDTH*2, 0, WIDTH, HEIGHT*0.88 - 45)];
self.bgView2.backgroundColor = [UIColor purpleColor];
self.bgView2.alpha = 0.5;
[self.bgScroll addSubview:self.bgView2];
}
