如何添加自定义控件

基于一键登录的拉起授权页面功能，如果想要在我们的授权页面中添加自定义组件，例如使用其他方式登录的按钮，来实现其他方式登录功能，为用户呈现更多选择登录的方式。本文介绍如何在一键登录授权界面中实现添加自定义控件功能，实现方式如下：

//自定义授权页面
-(void)setupAuthPageCustomStyle:(UIViewController *)authVC userInfo:(SVSDKHyProtocolUserInfo *)userInfo
{
    //授权页view
    UIView * authPageView = authVC.view;

    //中间可以对原有授权页上的按钮文字等作自定义操作

    ```

    //***添加自定义控件****
    // 自定义返回按钮
    UIButton *customBackButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [customBackButton setImage:[UIImage imageNamed:@"fh"] forState:UIControlStateNormal];
    [customBackButton setTitle:@"返回" forState:UIControlStateNormal];
    [customBackButton setTitleColor:[UIColor colorWithRed:35/255.0 green:35/255.0 blue:38/255.0 alpha:1/1.0] forState:UIControlStateNormal];
    customBackButton.titleLabel.font = [UIFont fontWithName:@"PingFangSC-Regular" size:18];
    [customBackButton addTarget:self.target action:@selector(customBackAction:) forControlEvents:UIControlEventTouchUpInside];
    [authPageView addSubview:customBackButton];

    UIView *bottomView = [[UIView alloc] init];
    [authPageView addSubview:bottomView];

    UILabel *mLbl = [[UILabel alloc] init];
    mLbl.textAlignment = NSTextAlignmentCenter;
    mLbl.font = [UIFont fontWithName:@"PingFangSC-Regular" size:13];
    mLbl.textColor = [UIColor colorWithRed:184/255.0 green:184/255.0 blue:188/255.0 alpha:1/1.0];
    mLbl.text = @"其他方式登录";
    [mLbl sizeToFit];

    [bottomView addSubview:mLbl];

    UIButton *wxBtn = [[UIButton alloc] init];
    [wxBtn setBackgroundImage:[UIImage imageNamed:@"wc"] forState:UIControlStateNormal];
    [wxBtn addTarget:self.target action:@selector(weixinLoginAction:) forControlEvents:UIControlEventTouchUpInside];
    [bottomView addSubview:wxBtn];

    UIButton *zhBtn = [[UIButton alloc] init];
    [zhBtn setBackgroundImage:[UIImage imageNamed:@"zh"] forState:UIControlStateNormal];
    [zhBtn addTarget:self.target action:@selector(usernameLoginAction:) forControlEvents:UIControlEventTouchUpInside];
    [bottomView addSubview:zhBtn];

    //布局(可以进行竖屏和横屏的布局)：自定义控件和授权页基本控件可以放一起统一布局即可

    ```
    //自定义控件布局（这里使用的是第三方布局控件Masonry）
    [customBackButton mas_remakeConstraints:^(MASConstraintMaker *make) {
        make.width.height.mas_equalTo(50);
        make.left.mas_equalTo(15);
        make.top.mas_equalTo(15);
    }];

    // bottomView
    [bottomView mas_remakeConstraints:^(MASConstraintMaker *make) {
        make.bottom.mas_equalTo(privacyTextView.mas_top);
        make.centerX.mas_equalTo(0);
        make.width.mas_equalTo(SVD_ScreenWidth);
        make.height.mas_equalTo(70+mLbl.bounds.size.height);
    }];

    [mLbl mas_remakeConstraints:^(MASConstraintMaker *make) {
        make.bottom.mas_equalTo(wxBtn.mas_top).offset(-10);
        make.centerX.mas_equalTo(0);
    }];

    [wxBtn mas_remakeConstraints:^(MASConstraintMaker *make) {
        make.bottom.mas_equalTo(-10);
        make.centerX.mas_equalTo(-50);
        make.width.height.mas_equalTo(48);
    }];

    [zhBtn mas_remakeConstraints:^(MASConstraintMaker *make) {
        make.top.equalTo(wxBtn);
        make.centerX.mas_equalTo(50);
        make.width.height.mas_equalTo(48);
    }];
