UISwitch 开关控件

改变大小需要设置transform

@property (nonatomic, strong) UISwitch      *matchOpenSwitch;

注意：调试 一下Switch的�x、y，以改变比例transform

    _switchBackView = [[UIView alloc] initWithFrame:CGRectMake([UIScreen mainScreen].bounds.size.width/375*335-15-35, [UIScreen mainScreen].bounds.size.width/375*(81-20)/2, [UIScreen mainScreen].bounds.size.width/375*35, [UIScreen mainScreen].bounds.size.width/375*20)];
    self.switchBackView.backgroundColor = [UIColor redColor];
    [self.openBackView addSubview:self.switchBackView];
    
    // 调试 一下matchOpenSwitch的�x、y
    _matchOpenSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(-[UIScreen mainScreen].bounds.size.width/375*10, -[UIScreen mainScreen].bounds.size.width/375*35/2/2, [UIScreen mainScreen].bounds.size.width/375*35, [UIScreen mainScreen].bounds.size.width/375*20)];
    self.matchOpenSwitch.onTintColor = RGBA(255, 196, 15, 1);
    //改变大小的关键代码（不能改变frame的大小，只能等比例缩放）
    self.matchOpenSwitch.transform = CGAffineTransformMakeScale(0.7, 0.7);
    [self.switchBackView addSubview:self.matchOpenSwitch];
    [self.matchOpenSwitch addTarget:self action:@selector(changeOpenSwitchAction:) forControlEvents:UIControlEventValueChanged];
    [self.matchOpenSwitch setOn:NO animated:YES];

- (void)changeOpenSwitchAction:(UISwitch *)mySwitch {
    /** ：默认 未开启 控件switch */
    
    if ([mySwitch isOn]) {
        [LCM_AlertViewFactory showToastWithMessage:@"打开"];
    } else {
        [LCM_AlertViewFactory showToastWithMessage:@"关闭"];
    }
