UISwitch 开关

属性

• 创建

UISwitch *switchView = [[UISwitch alloc]initWithFrame:CGRectMake(54.0f,16.0f,100.0f,28.0f)];

• 设置UISwitch的初始化状态

switchView.on = YES; //设置初始为ON的一边
[switchView setOn:YES];

• UISwitch事件的响应

[switchView addTarget:self action:@selector(switchAction:) forControlEvents:UIControlEventValueChanged];
-(void)switchAction:(id)sender {
  BOOL isButtonOn = [switchButton isOn];
  if (isButtonOn) {
      showSwitchValue.text = @"是";
  }else {
      showSwitchValue.text = @"否";
  }
}

• 控件大小不能设置frame,只能用缩放比例

switchView.transform = CGAffineTransformMakeScale(0.75,0.75);

• UISwitch的颜色

switchView.onTintColor = [UIColor colorWithRed:0.984 green:0.478 blue:0.224 alpha:1.000];
