写在前面

以下都是项目初期搭建UI中遇到的一些小细节问题，在此简单记录下来，方便以后查阅，大神不喜勿喷，请绕过哦~，后期会陆续更新项目实施大致框架及协同开发的一些相关信息，嘿嘿，给自己不任务了，哈哈

1.实现两个按钮之间的竖条分割符

初步搭建的个人中心首页，下面代码实现类似图中标识的竖条

法一：

    UIView *vSeperater = [[UIView alloc] init];
    vSeperater.frame = CGRectMake(kScreenWidth/2-1, -25, 1, 45);
    vSeperater.backgroundColor = [UIColor whiteColor];
    [btn addSubview:vSeperater];

法二：

    CALayer *bottomBorder = [CALayer layer];
    bottomBorder.frame = CGRectMake(kScreenWidth/2-1, -25, 1, 45);
    bottomBorder.backgroundColor = [UIColor whiteColor].CGColor;
    [btn.layer addSublayer:bottomBorder];

2.设置button字体颜色

下面代码是摘自网上的，个人适当的改下，注释的方法设置字体是不会起作用的

    UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [customButton setTitleColor:_btnFontColor forState:UIControlStateNormal];
    //  customButton.titleLabel.textColor = _btnFontColor;

3.导航栏背景颜色和透明度设置

背景颜色设置

self.navigationController.navigationBar.barTintColor = kColorHeadPerson;

禁用透明度

self.navigationController.navigationBar.translucent = NO;

相应页面隐藏导航栏和底部tab栏

-(void)viewWillAppear:(BOOL)animated{
    
    [super viewWillAppear:animated];
    
    [self.navigationController setNavigationBarHidden:NO animated:YES];
    self.tabBarController.tabBar.hidden = YES;
}
- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    
    self.tabBarController.tabBar.hidden = NO;
}

4.imgview上button点击事件不起作用问题

cell上添加imgview，之后在该imgview上布局三个button，button的点击事件不起作用，解决方法：将imageview换成uiview，ok。主要代码如下：

        UITableViewCell *cell = [[UITableViewCell alloc]init];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        cell.accessoryType = UITableViewCellAccessoryNone;
        
        UIView *superView = cell;
        //充值，提现，资产
        UIView *vBg = ({
            UIView *view = [UIView new];
            view.backgroundColor = [UIColor whiteColor];
            [superView addSubview:view];
            [view mas_makeConstraints:^(MASConstraintMaker *make) {
                make.left.equalTo(superView.mas_left).offset(0);
                make.right.equalTo(superView.mas_right).offset(0);
                make.bottom.equalTo(superView.mas_bottom).offset(0);
                make.height.equalTo(@60);
            }];
            view;
        });
        
        UIButton *btnCharge =({
            UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
            [btn setTitle:@"充值" forState:UIControlStateNormal];
            btn.titleLabel.font = SYSTEMFONT(22);
            [btn setTintColor:kColorHeadPerson];
            [btn addTarget:self action:@selector(clickCharge) forControlEvents:UIControlEventTouchUpInside];
            [vBg addSubview:btn];
            
            CALayer *bottomBorder = [CALayer layer];
            bottomBorder.frame = CGRectMake(kScreenWidth/3-1, 20, 1, 25);
            bottomBorder.backgroundColor = [UIColor lightGrayColor].CGColor;
            [btn.layer addSublayer:bottomBorder];
            
            btn;
        });
        UIButton *btnWithdraw =({
            UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
            [btn setTitle:@"提现" forState:UIControlStateNormal];
            btn.titleLabel.font = SYSTEMFONT(22);
            [btn setTintColor:kColorHeadPerson];
            [btn addTarget:self action:@selector(clickWithdraw) forControlEvents:UIControlEventTouchUpInside];
            [vBg addSubview:btn];
            
            CALayer *bottomBorder = [CALayer layer];
            bottomBorder.frame = CGRectMake(kScreenWidth/3-1, 20, 1, 25);
            bottomBorder.backgroundColor = [UIColor lightGrayColor].CGColor;
            [btn.layer addSublayer:bottomBorder];
            
            btn;
        });
        UIButton *btnAsset =({
            UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
            [btn setTitle:@"资产" forState:UIControlStateNormal];
            btn.titleLabel.font = SYSTEMFONT(22);
            [btn setTintColor:kColorHeadPerson];
            [btn addTarget:self action:@selector(clickAsset) forControlEvents:UIControlEventTouchUpInside];
            [vBg addSubview:btn];
            btn;
        });
        
        [btnCharge mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(vBg.mas_left);
            make.right.equalTo(btnWithdraw.mas_left);
            make.width.equalTo(btnAsset.mas_width);
            make.width.equalTo(btnWithdraw.mas_width);
            make.height.equalTo(vBg);
        }];
        [btnWithdraw mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(btnCharge.mas_right);
            make.right.equalTo(btnAsset.mas_left);
            make.width.equalTo(btnAsset.mas_width);
            make.width.equalTo(btnCharge.mas_width);
            make.height.equalTo(vBg);
        }];
        [btnAsset mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.equalTo(btnWithdraw.mas_right);
            make.right.equalTo(vBg.mas_right);
            make.width.equalTo(btnCharge.mas_width);
            make.width.equalTo(btnWithdraw.mas_width);
            make.height.equalTo(vBg);
        }];
        return cell;

5.Masonry约束问题

关于Masonry约束问题编译报错：

在使用Masonry布局之前，确保subview已经被add父view上。

关于控制台显示约束出现问题，去fix it的时候，一般按照提示，给每个布局小部分打断点跟踪调试，一般就可以就解决。

6.button懒加载失败问题

把如下代码放在懒加载里面，页面上的button是出不来的，放在viewdidload里面是ok的，这里原因还不太清楚，应该跟懒加载的相关机制有关。

    [self.btnFetchPwd mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.equalTo(self.view.mas_left).offset(20);
        make.right.equalTo(self.view.mas_right).offset(-20);
        make.top.equalTo(self.tableview.mas_bottom).offset(20);
        make.height.equalTo(@60);
    }];
