UIController

一。分段控件(UISegmentedControl)

UISegmentedControl *segment = [[UISegmentedControl alloc ] initWithItems : @ [ @"1",@"2",@"3"] ];            //@[ ] 表示快速创建数组


(1)给segmentedControl绑定方法

    [segment addTarget:self action:@selector(segmentedAction:) forControlEvents:UIControlEventValueChanged];

    

(2)改变segment的颜色。。。

    [segment setTintColor:[UIColor purpleColor]]; //填充色

    [segment setBackgroundColor:[UIColor yellowColor]];

    

(3)设置背景图片

    [segment setBackgroundImage:[UIImage imageNamed:@"1.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];




二。滑动条控件(UISlider)

UISlider *slider = [[UISlider alloc]initWithFrame:CGRectMake(20, 60, 280, 50)];

    [slider addTarget:self action:@selector(sliderAction:) forControlEvents:(UIControlEventValueChanged)];


(1)设置selder最大值,最小值

[slider setMaximumValue:100];

[slider setMinimumValue:10];


(2)控件前后图片

slider setMaximumValueImage:(UIImage *)




三,UIStepper

UIStepper *stepper = [[UIStepper alloc]initWithFrame:CGRectMake(20, 110, 30, 30)];

    [stepper addTarget:self action:@selector(stepperAction:) forControlEvents:(UIControlEventValueChanged)];




四。UISwitch

UISwitch *switch1 = [[UISwitch alloc] initWithFrame:CGRectMake(150, 110, 30, 30)];

    [switch1 addTarget:self action:@selector(switchAction:) forControlEvents:(UIControlEventValueChanged)];



五。UIImageView

利用UIImageView播放gif动图

(1)将图片数组给imageView 等待播放

imageView.animationImages = imageArr;


 ( 2 ) 播放速度(播放一遍需要的秒数)

imageView.animationDuration = 2       


(3)播放次数

imageView。animationRepeatCount = 0 ;        //默认为0            0和 -1 代表次数无限


(4)播放

[imageView startAnimating];
