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viewUIView * 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);}];}
