UI控件使用案例<一>

1. //********UISegmentedControl**********
UIImage *image = [UIImageimageNamed:@"2.png"];
NSArray *arr = @[@"分组",@"全部",@"推荐",image];//不能在一个seg里面既有文字又有图片
UISegmentedControl *control = [[UISegmentedControl alloc]initWithItems:arr];

[control addTarget:selfaction:@selector(changeColor:) forControlEvents:UIControlEventValueChanged];
control.selectedSegmentIndex = 1;//开始的时候就选中一个下标
[controlsetTitle:@"喜欢" forSegmentAtIndex:3];//给指定下标设置标题
//还可以设置指定下标的宽度
//可以获取指定下标的宽度

control.frame =CGRectMake(60, 100, 200, 40);
control.backgroundColor = [UIColor whiteColor];
[self.viewaddSubview:control];
[controlrelease];

2. //*********UISlider滑块***********
UISlider*slider = [[UISlider alloc] initWithFrame:CGRectMake(20, 400, 280, 5)];
[self.viewaddSubview:slider];
[slideraddTarget:self action:@selector(red:)forControlEvents:UIControlEventValueChanged];
slider.minimumValueImage = [UIImage imageNamed:@"2.png"];//给最小值处加图片
// slider.maximumValue = 1;
// slider.minimumValue = 0;
//slider.transform =CGAffineTransformMakeRotation(M_PI_2*3);//滑块垂直状态

[sliderrelease];

UISlider*slider2 = [[UISlider alloc] initWithFrame:CGRectMake(20, 360, 280, 5)];
[self.viewaddSubview:slider2];
// slider2.maximumValue = 1;
// slider2.minimumValue = 0;
[slider2addTarget:self action:@selector(green:)forControlEvents:UIControlEventValueChanged];
slider2.minimumValueImage = [UIImage imageNamed:@"2.png"];//给最小值处加图片

[slider2 release];

3. //******用滑块控制播放图片速度*******
UIImageView*imageView = [[UIImageView alloc] initWithFrame:CGRectMake(20, 50, 100, 100)];

NSMutableArray*images = [NSMutableArray arrayWithCapacity:14];//创建一个存放图片的动态数组
for (int i = 0;i <= 12; i++) {//把动画依次加入数组
NSString*imageName = [NSString stringWithFormat:@"VMCXT6R3EB4P3VN@]UIN({X－%d（被拖移）.tiff",i];
UIImage*image = [UIImage imageNamed:imageName];
[imagesaddObject:image];
}
imageView.animationImages = images;//添加播放数组
imageView.animationDuration= 1;//动画播放速度
[imageViewstartAnimating];//开始播放
//imageView.animationRepeatCount = 4;//动画播放次数
imageView.backgroundColor = [UIColor grayColor];
imageView.tag =1000;
[self.viewaddSubview:imageView];
[imageViewrelease];

UISlider*slider5 = [[UISlider alloc] initWithFrame:CGRectMake(20, 400, 280, 5)];
[self.viewaddSubview:slider5];

[slider5addTarget:self action:@selector(run:)forControlEvents:UIControlEventValueChanged];
slider5.minimumValueImage= [UIImage imageNamed:@"2.png"];//给最小值处加图片

[slider5 release];
***********方法*********
-(void)run:(UISlider *)slider
{
UIImageView *view = (UIImageView*)[self.view viewWithTag:1000];
[view stopAnimating];
view.animationDuration = slider.value;
[view startAnimating];

}

4. //************UIControl的学习**********
//UIControl是很多种控制类的父类,例如:
//UIButton(响应点击操作的控件),
//UITextField(响应输入的控件),
//UISlider(响应滑动的控件),
//UISegmentedControl(分段控件),
//UISwitch(开关),
//UIStepper(递增,递减控件)等等
//凡是需要响应用户控制的类,都继承与UIControl
//UIControl作为基类,封装了事件的分发功能,封装了触发时机(枚举值,touchUpInside,valueChanged等).
//你可以通过addTarget:action:forControlEvents:给UIControl及其子类添加事件(一个控件可以添加多个target-action对)
//也可以通过removeTarget:action:forControlEvents:从UIControl及其子类中移除事件

UITextField*tff = [[UITextField alloc] initWithFrame:CGRectMake(60, 60, 200, 30)];
tff.borderStyle= UITextBorderStyleRoundedRect;
[self.viewaddSubview:tff];
tff.tag = 102;
[tff release];

1. //********UISegmentedControl**********
UIImage *image = [UIImageimageNamed:@"2.png"];
NSArray *arr = @[@"分组",@"全部",@"推荐",image];//不能在一个seg里面既有文字又有图片
UISegmentedControl *control = [[UISegmentedControl alloc]initWithItems:arr];

[control addTarget:selfaction:@selector(changeColor:) forControlEvents:UIControlEventValueChanged];
control.selectedSegmentIndex = 1;//开始的时候就选中一个下标
[controlsetTitle:@"喜欢" forSegmentAtIndex:3];//给指定下标设置标题
//还可以设置指定下标的宽度
//可以获取指定下标的宽度

control.frame =CGRectMake(60, 100, 200, 40);
control.backgroundColor = [UIColor whiteColor];
[self.viewaddSubview:control];

// slider.maximumValue = 1;
// slider.minimumValue = 0;
//slider.transform =CGAffineTransformMakeRotation(M_PI_2*3);//滑块垂直状态

[sliderrelease];

UISlider*slider2 = [[UISlider alloc] initWithFrame:CGRectMake(20, 360, 280, 5)];
[self.viewaddSubview:slider2];
// slider2.maximumValue = 1;
// slider2.minimumValue = 0;
[slider2addTarget:self action:@selector(green:)forControlEvents:UIControlEventValueChanged];
slider2.minimumValueImage = [UIImage imageNamed:@"2.png"];//给最小值处加图片
