UI 第六节 uisegmentedControl uiimage uislider 课后习题

作业1:使⽤UISegmentedControl切换登录界⾯、注册界面,找回密码界 面。

#import "ViewController.h"

@interface ViewController ()

@property(nonatomic, retain)UISegmentedControl *segment;


@end

@implementation ViewController

{

}

- (void)viewDidLoad {

    [self loadSegment];
}


// 自定义方法

{

    self.segment.frame = CGRectMake(10, 30, self.view.frame.size.width - 20, 30);
    [self.segment addTarget:self action:@selector(change:) forControlEvents:UIControlEventValueChanged];
    
    
    [self.view addSubview:_segment];
    [self.segment release];
}

-(void)change:(UISegmentedControl *)sender
{
    //判断 把没有sender的界面全部移除
    for(UIView *aview in self.view.subviews)
        if (aview != sender) {
            
            [aview removeFromSuperview];
        }

作业2:

创建3个UISlider对象。⽤用这3个UISlider对象控制 self.view.backgroundColor的变化。 3个UISlider对象分别控制UIColor的red,green,blue。 滑动任何⼀一个UISlider都会引起背景颜⾊色变化。
#import "ViewController.h"

@interface ViewController ()

@property(nonatomic, retain)UISlider *s1;
@property(nonatomic, retain)UISlider *s2;
@property(nonatomic, retain)UISlider *s3;
@property(nonatomic, retain)UIImageView *imageView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self loadSlider];
    [self loadNewView];
    self.view.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
    
    
}

-(void)dealloc
{
    [super dealloc];
    [self.s1 release];
    [self.s2 release];
    [self.s3 release];
    [self.imageView release];
    
}

//设置属性,添加s1,s2,s3的三种value 取值范围在0~1
-(void)loadSlider
{
    self.s1 = [[UISlider alloc]initWithFrame:CGRectMake(40, 50, self.view.frame.size.width - 80, 30)];
    self.s1.minimumTrackTintColor = [UIColor redColor];

    [self.s2 addTarget:self action:@selector(change:) forControlEvents:UIControlEventValueChanged];
    [self.s3 addTarget:self action:@selector(change:) forControlEvents:UIControlEventValueChanged];
