今天給大家做個兩個互斥效果，廢話不說 直接上代碼

創(chuàng)建兩個全局按鈕 其中兩個按鈕的觸發(fā)方法一樣

@property (nonatomic,strong)UIButton *normalBtn;

@property (nonatomic,strong)UIButton *fastBtn;

self.normalBtn = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];

? ? [self.normalBtn setImage:[UIImage imageNamed:@"show_Car"] forState:0];

? ? [self.normalBtn setImage:[UIImage imageNamed:@"hidden_Car"] forState:UIControlStateSelected];

? ? [self.normalBtn addTarget:self action:@selector(btnTouch:) forControlEvents:UIControlEventTouchUpInside];

? ? [self.viewaddSubview:self.normalBtn];

? ? self.fastBtn = [[UIButton alloc]initWithFrame:CGRectMake(100, 300, 100, 100)];

? ? [self.fastBtn setImage:[UIImage imageNamed:@"hidden_Parking"] forState:0];

? ? [self.fastBtn setImage:[UIImage imageNamed:@"show_Parking"] forState:UIControlStateSelected];

? ? [self.fastBtn addTarget:self action:@selector(btnTouch:) forControlEvents:UIControlEventTouchUpInside];

? ? [self.viewaddSubview:self.fastBtn];

下面就是觸發(fā)方法

-(void)btnTouch:(UIButton*)sender

{

? ? if(sender.selected==YES) {

? ? ? ? self.fastBtn.selected= !self.fastBtn.selected;

? ? }else{

? ? ? ? sender.selected= !sender.selected;

? ? }

? ? ? ? self.normalBtn.selected = !self.normalBtn.selected;

}

這樣兩個完美的互斥效果的按鈕就完成了 是不是很簡單
