UIControll控制类
addTarget:action:forControllEvents:
添加响应事件(满足什么条件下 让某人调用方法)
UISegmentedControl
UISegmentedControl *seg=[[UISegmentedControl alloc] initWithtems:@[@"消息" ，@"电话"，@"微信"]];
seg.Frame = CGRectMake(100,100,200,40);
[self.view addSubview:seg];
[seg release];
选中分段下标
seg.selectedSegmentIndex = 0;
一般不设置背景颜色 若要设置跟其他设置颜色的方法一样。
渲染颜色
seg.tintColor = [UIColor lightGrayColor];
插入新的分段
[seg insertSegmentWithTitle:@"陌陌" atIndex:2 animated:YES];
创建两个不同颜色的view
self.redv = [[UIView alloc]initWithFrame:CGRectMake(50,200,300,300)];
self.redv.backgrounderColor = [UIColor refColor];
[self.view addSubview:self.redv];
[_redv release];
相同的方法再建另一个颜色
分段控制器的方法调用
-(void)segAction:(UISegmentedControl *)seg｛if（seg.selectedSegmentIndex == 0）
[UIView transitionFrameView:self.greenV toView:self.redv duration:1 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished){
｝];
}
if（seg.selectedSegmentIndex == 1）｛
[UIView TransitionFromView:self.redv toView:self.greenV duration:1 options:UIViewAnimationOptionTransitionFileFromLeft completion:^(BOOL finished){
}];
｝
UISlider滑块控制器
UISlider *sl = [[UISlider alloc] initWithFrame:CGRectMake(50,50,250,50)];
sl.backgroundColor = [UIColor yellowColor];
[self.view addSubview:sl];
[sl release];
颜色设置:
划过距离的颜色(滑块左)
sl.minimumTrackTintColor = [UIColor blackColor];
未划过的距离颜色（滑块右）
sl.maxmumTrackTintColor =[UIColor redColor];
滑块颜色:
sl.thumbTintColor =[UIColor greenColor];
添加响应事件:
[sl.addTarget:self action:@selection(sliderAction:)forControlEvents:UIControlEventValueChanged];
滑动范围:
最小值:
sl.minimumValue = -100;
最大值:
sl.maximumValue = 1000;
更新滑块的起始点:
sl.value = -100;
滑块控制器的方法调用:
-(void)sliderAction:(UISlider *)sl{
NSLog(@"％f",sl.value);
}
页码控制器:
UIPageControl *pc = [[UIPageControl alloc]initWithFrame:CGRectMake:(50,150,100,50)];
pc.backgroundColor = [UIColor blackColor];
[self.view addSubview:pc];
[pc release];
页数:
pc.numberOfPages = 4;
当前页:
pc.currentPage = 3;
页码颜色:
pc.pageIndicatorTintColor = [UIColor greenColor];
当前页颜色:
pc.currentPageIndicatorTintColor = [UIColor redColor];
响应事件:
[pc.addTarget:self action:@selection(pageAction:)forControlEvents:UIControlEventValueChanged];
页码控制器的方法调用:
-(void)pageAction:(UIPageControl *)page{
NSLog(@"％ld",page.currentPage);
}
开关控制器:
UISwitch *sw = [[UISwitch alloc]initWithFrame:CGRectMake(250,150,100,50)];
sw.backgroundColor = [UIColor whiteColor];
[self.view addSubview:sw];
[sw addTarget:self action:@selector(switchAction:)forControlEvents:UIControlEventValueChanged];
[sw release];
开关属性:
sw.on = YES;
sw.tintColor = [UIColor blackColor];
sw.thumbTintColor = [UIColor redColor];
sw.onTintColor = [UIColor purpleColor];
开关判断:
-(void)switchAction:(UISwitch *)sw{
if(sw.on){
NSLog(@"开启");
}else{
NSLog(@"关闭");
}
}
