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];
    }
}}
