【iOS】UISwitch

• 初始化
  

  UISwitch *switch= [ [ UISwitch alloc ] initWithFrame: CGRectMake(200, 10, 0, 0) ]; switch.on = NO; switch.tag = 2; [switch addTarget:self action:@selector(switchAction:) forControlEvents:UIControlEventValueChanged]; [self addSubview: jumpToNextAuto];

• 縮小要用 transform
  

  switch.transform = CGAffineTransformMakeScale(0.75, 0.75);
