UIControl

UISwitch->UIControl->UIView
1、实例化
UISwitch* switch1 = [[UISwitch alloc] initWithFrame:CGRectMake(20, 50, 1000, 2000)];
2、添加
[self.view addSubview:switch1];
3、开关状态
switch1.on = YES;
4、设置颜色 onTintColor description: The color used to tint the appearance of the switch when it is turned on.
switch1.onTintColor = [UIColor yellowColor];
5、设置开关颜色 tintColor description: The color used to tint the outline of the switch when it is turned off.
6、添加事件
[switch1 addTarget:self action:@selector(switchClick:) forControlEvents:UIControlEventValueChanged];
UIActivityIndicatorView->UIView
1、实例化 UIActivityIndicatorView* activity = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
2、中点
activity.center = CGPointMake(100,100);
3、开始动画
[activity startAnimating];
4、结束动画
[activity stopAnimating];
5、添加
[self.view addSubview:activity];
6、系统加载小菊花
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
UIStepper->UIControl->UIView
1、实例化
UIStepper *step = [[UIStepper alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
2、添加
[self.view addSubview:step];
3、设置最大值
step.maximumValue = 100;
4、设置最小值
step.minimumValue = 0;
5、设置初始值
step.value = 50;
6、设置递变量
step.stepValue = 8;
7、添加操作
[step addTarget:self action:@selector(stepClick:) forControlEvents:UIControlEventValueChanged];
注意观察事件为UIControlEventValueChanged
UIProgressView->UIView
1、初始化
UIProgressView* progressView = [[UIProgressView alloc] initWithFrame:CGRectMake(30, 210, 260, 0)];
2、添加
[self.view addSubview:progressView];
3、设置初始值 progress //进度条的取值范围0.0-1.0
progressView.progress = 0.5;
4、设置进度条颜色 tintColor
progressView.tintColor = [UIColor greenColor];
UISlider->UIControl->UIView
1、实例化
UISlider* slider = [[UISlider alloc] initWithFrame:CGRectMake(30, 240,260 ,30)];
2、设置最大值
slider.maximumValue = 100;
3、设置最小值
slider.minimumValue = 0;
4、初始化
slider.value = 50;
5、是否及时更新
slider.continuous = NO;
6、添加
[self.view addSubview:slider];
UISegmentedControl->UIColor->UIView
1、实例化
NSArray* array = @[@”第一个”,@”第二个”,@”第三个”];//数组中的值可为图片或文字
UISegmentedControl* segment = [[UISegmentedControl alloc] initWithItems:array];
2、btn颜色
segment.tintColor = [UIColor colorWithRed:0.5 green:0.5 blue:0.5 alpha:0.8];
3、默认选中
segment.selectedSegmentIndex = 1;
4、新增选项
[segment insertSegmentWithTitle:@”第四个” atIndex:3 animated:NO];

以上为对UISwitch、UIActivityIndicatorView、UIStepper、UISlider、UIProgress、UISegmentedControl的总结
