UIButton和UISlider

UIButton

主要功能：按钮控件，主要用于与用户操作进行交互

常用属性及方法

系统内建的按钮类型

UIButtonTypeCustom

UIButtonTypeSystem

UIButtonTypeDetaiDislosure

UIButtonTypeInfoLight

UIButtonTypeContactAdd

UIButtonTypeRoundedRect

系统中关于控件的状态类型

UIControlStateNormol

UIControlStateHighlighted

UIControlStateDisabled

UIControlStateSelected

UIControlStateApplication

UIControlStateReserved

几种常见设置UIButton方法

//根据UIButtonType创建不同天系统内建风格的按钮+ (id)buttonWithType:(UIButtonType)buttonType;eg:UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];//根据按钮状态设置按钮的标题- (void)setTitle:(NSString *)title forState:(UIControlState)state;[button setTitle:@"BTN" forState:UIControlStateNormal];//根据按钮状态设置按钮上的文字颜色- (void)setTitleColor:(UIColor *)color forState:(UIControlState)state;eg:[button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];//根据按钮状态设置按钮的图片- (void)setImage:(UIImage *)image forState:(UIControl)eg:[button setImage:[UIImage imageNamed:@"xiaogou.jpg"] forState:UIControlStateNormal];//根据按钮状态设置背景图片- (void)setBackgroundImage:(UIImage *)image forState:(UIControlState)stateeg:[button setBackgroundImage:[UIImage imageNamed:@"xiaogou.jpg"] forState:UIControlStateNormal];//给按钮添加目标及行为- (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEventseg:[button addTarget:self action:@selector(onButton) forControlEvents:UIControlEventTouchUpInside];

UISlider

主要功能：滑块属性，用于控制某一范围内值得设置，如声音大小控制，音乐播放进度。

常用属性和方法：

@property(nonatomic) float value;//在某一时刻或者某一位置UISlider所表示的值，默认是0.0NSLog(@"%f",self.slider.value);@property(nonatomic) float minimumValue;//UISlider坐标是范围的最小值。默认是0.0NSLog(@"%f",self.slider.minimumValue);@property(nonatomic) float maximumValue;//UISlider所表示范围的最大值，默认是1.0//最小值时的图片，在UISlider的左边，默认是nil@property(nonatomic, retain) UIImage *minimumValueImage;self.slider.minimumValueImage = [UIImage imageNamed:@"xiaogou.jpg"];//最大值是的图片，在UISlider的右边，默认是nil@property(nonatomic, retain) UIImage *maximumValueImage;self.slider.maximumValueImage = [UIImage imageNamed:@"xiaogou.jpg"];//设置UISlider对象的值- (void) setValue:(float)value animated:(BOOL)animated;- //让滑块以一定的速度自动滑动

代码演示：

让滑块自动的以一定的速度滑动

#import "ViewController.h"@interface ViewController ()@property (weak,nonatomic) UISlider *slider;//滑块控件是拖拽过来的@end@implementation ViewController- (void)viewDidLoad {    self.slider.minimumValue = 0.0;    self.slider.maximumValue = 1000.0;    self.slider.minimumTrackTintColor = [UIColor redColor];    self.slider.maximumTrackTintColor = [UIColor greenColor];    self.slider.thumbTintColor = [UIColor purpleColor];    UIButton *btnType = [UIButton buttonWithType:UIButtonTypeRoundedRect];    btnType.backgroundColor = [UIColor blueColor];    btnType.frame = CGRectMake(100,300,100,60);    [self.view addSubview:btnType];- (void)onTimer:(NSTimer *)timer{    static float value = 10;    value +=5;    [self.slider setValue:value animated:YES];    NSLog(@"%f",self.slider.value);}- (void)onButton{    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(onTimer:) userInfo:nil repeats:NO];}- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}}
