一、iOS Button数组创建单选效果

- (void)respondsToOn:(UIButton*)sender{sender.selected = !sender.selected;for (NSInteger i = 0; i < self.btnArray.count; i++) {    UIButton *btn = self.btnArray[i];    if (sender.tag == i) {        btn.selected = sender.selected;        if ([self.delegate respondsToSelector:@selector(visitOnclickBtn:)]) {            [self.delegate visitOnclickBtn:sender.tag];        }        btn.backgroundColor = [LJColor_RGB colorWithHexString:@"15588c"];        [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];    }else{        btn.selected = NO;        btn.backgroundColor = [UIColor whiteColor];        [btn setTitleColor:[LJColor_RGB colorWithHexString:@"15588c"] forState:UIControlStateNormal];    }}}
