iOS按钮点击选中与被选中切换

其实这个没什么记的，初始化按钮给按钮分别设置选中时对图片和被选中时的图片，给按钮添加方法，在方法中实现三句话就OK了，下面直接看代码：

首先在.m中声明一个按钮

    @property (nonatomic, strong) UIButton *selecBtn;

//初始化按钮UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];//给按钮设置图片[button setBackgroundImage:[UIImage imageNamed:imageArray[i]] forState:UIControlStateNormal];[button setBackgroundImage:[UIImage imageNamed:SeleimageArray[i]] forState:UIControlStateDisabled];            //添加方法[button addTarget:self action:@selector(changeDataButton:) forControlEvents:UIControlEventTouchDown];

然后在方法中如下：

    - (IBAction)btnClick:(UIButton *)btn {    self.selecBtn.enabled = YES;    btn.enabled = NO;    self.selecBtn = btn;    }

ok!齐活
