iOS常用小控件集合
//【UISlider】一个滑块控件,高度固定(31)-事件驱动型控件 UISlider *sl = [[UISlider alloc] initWithFrame:CGRectMake(10,74,300,50)]; //设置最大最小值 sl.minimumValue = 0.0; sl.maximumValue = 100.0; //设置滑块当前指示的值 sl.value = 50.0; //值是否连续变化 sl.continuous = NO; //滑块的值 @property(nonatomic) float value; //设置滑块的最小值(默认最小和最大分别是0.0和1.0) @property(nonatomic) float minimumValue; //设置滑块的最大值 @property(nonatomic) float maximumValue; //滑动时是否触发事件(默认是yes) @property(nonatomic,getter=isContinuous) BOOL continuous; - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents; //最后一个参数写UIControlEventValueChanged,监控滑动状态 //滑动时触发,如果continuous设为no的话就滑动结束时触发,打印slider.value /**********************【UISegmentedControl】分段选取器************************/ NSArray *titles = @[@"火影",@"海贼王"]; UISegmentedControl *seg = [[UISegmentedControl alloc] initWithItems:titles]; seg.frame = CGRectMake(10,150,300,30); //设置选中的分段 seg.selectedSegmentIndex = 0; //插入新的分段 [seg insertSegmentWithTitle:@"银魂" atIndex:1 animated:YES]; //初始化传递进去的NSArray可以用字符串或图片 - (id)initWithItems:(NSArray *)items; //设置frame //设置风格样式(ios7中被禁用了) @property(nonatomic) UISegmentedControlStyle segmentedControlStyle; //设置哪个分段处于选中状态,不设置此属性,任何分段都处于非选中状态 @property(nonatomic) NSInteger selectedSegmentIndex; //插入和删除某个分段 - (void)insertSegmentWithTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated; - (void)removeSegmentAtIndex:(NSUInteger)segment animated:(BOOL)animated; //删除所有分段,相当于把这个选取器给删了。。。 - (void)removeAllSegments; - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents; //最后一个参数写UIControlEventValueChanged,监控点击状态 //点击时触发 //根据分段的下标,拿到分段的标题 - (NSString *)titleForSegmentAtIndex:(NSUInteger)segment; /**********************【UISwitch】************************/ //【UISwitch】//开关控件,事件驱动型控件,固定大小51*31,frame中设置大小无效 //开关的打开状态 UISwitch * st = [[UISwitch alloc] initWithFrame:CGRectMake(10, 74, 300, 50)]; //on 控制开关开闭的属性 st.on = YES; //UIControlEventValueChanged 控件值改变是,让id执行SEL [st addTarget:self action:@selector(stChanged:) forControlEvents:UIControlEventValueChanged]; @property(nonatomic,getter=isOn) BOOL on; - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents; //最后一个参数写UIControlEventValueChanged //点击开关时触发 /**********************【UIActivityIndicatorView】************************/ //加载等待提示控件,初始化的时候,设定风格样式,(联网小菊花) UIActivityIndicatorView * indicatorView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; //center设置视图中心点的坐标(CGPoint),一般直接设置中心点为view的中心点 indicatorView.center = self.view.center; indicatorView.tag = 300; //startAnimating 开始转动 - (id)initWithActivityIndicatorStyle:(UIActivityIndicatorViewStyle)style; //UIActivityIndicatorViewStyleWhiteLarge,//控件的size固定 //开始旋转和停止 - (void)startAnimating; - (void)stopAnimating; //用switch控制activity 的旋转状态 /**********************【UIStepper】步进器************************/ //步进器 固定的size (94*27)修改无效, 事件驱动型控件 UIStepper *st = [[UIStepper alloc] initWithFrame:CGRectMake(10,74,300,30)]; st.value = 10; //最值 st.minimumValue = 10; st.maximumValue = 300; st.continuous = NO; //步长 + 一次增加的值 st.stepValue = 10; //步进器的值 @property(nonatomic) double value; //最小和最大值(默认0到100) @property(nonatomic) double minimumValue; @property(nonatomic) double maximumValue; //设置步长 (默认值为1 必须>0)(加减的时候改变的值) @property(nonatomic) double stepValue; - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents; //最后一个参数写UIControlEventValueChanged //点击加减的时候触发 /******************【UIProgressView】进度条,用于展示进度************************/ //进度条,高度固定为2,设置无效 UIProgressView *progress = [[UIProgressView alloc] initWithFrame:CGRectMake(10,150,300,20)]; //反映进度 progress (0.0-1.0) progress.progress =0.5; //进度条的值 固定为0到1 @property(nonatomic) float progress; //用stepper控制progress的进度 /******************【UIWebView】网页视图************************/ UIWebView *_webView = [[UIWebView alloc] initWithFrame:self.view.bounds]; NSURL *url = [NSURL URLWithString:@"http://m.jd.com"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [_webView loadRequest:request]; [self.view addSubview:_webView]; [_webView release]; /******************【UIAlertView】警示框 重要************************/ UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"温馨提示" message:@"流量用尽" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定",nil]; //展示警告框 [alert show]; //代理 <UIAlertViewDelegate> //代理方法 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ NSLog(@"buttonIndex:%d",buttonIndex); } /******************【UIActionSheet】 事件表格************************/ //代理 <UIActionSheetDelegate> UIActionSheet *ac = [[UIActionSheet alloc] initWithTitle:@"分享" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"新浪微博",@"腾讯微博",nil]; //从当前视图中,呈现出来 [ac showInView:self.view]; [sheet showInView:self.view]; [sheet release]; //事件表代理方法 - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{ NSLog(@"sheet index:%d",buttonIndex);
