iphone UISwitch开关控件

本例子是创建两个开关控件，点击其中的一个开关的时候，另外一个开关也随着变化。

。声明：

//两个按钮

UISwitch *_leftSwitch;

UISwitch *_rightSwitch;

。初始化：

_leftSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(50, _startY, 60, 30)];

_leftSwitch.tag = 0;

[_leftSwitch addTarget:self action:@selector(switchPress:) forControlEvents:UIControlEventValueChanged];

_rightSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(170, _startY, 30, 15)];

_rightSwitch.tag = 1;

[_rightSwitch addTarget:self action:@selector(switchPress:) forControlEvents:UIControlEventValueChanged];

。添加视图：

[self.view addSubview:_leftSwitch];

[self.view addSubview:_rightSwitch];

。释放：

[_leftSwitch release];

[_rightSwitch release];

。触发函数：

#pragma mark -

#pragma mark UISwitch Event

-(void)switchPress:(UISwitch*)inSwitch{

NSLog(@"switchPress tag:%d", inSwitch.tag);

switch (inSwitch.tag) {

case 0:

{

[_rightSwitch setOn:inSwitch.on animated:YES];

break;

}

case 1:

{

[_leftSwitch setOn:inSwitch.on animated:YES];

break;

}

}

}
