在处理UITableView表格时，我们希望在View底部添加按钮。
用户拖动UITableView时按钮能跟随移动。
如题，实现如下界面：
– (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section{if (section >= kSetSetting) {return 80;}else{return 2;}}- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{if (section >= kSetSetting){UIView *footerView = [[UIView alloc] init];footerView.userInteractionEnabled = YES;footerView.backgroundColor = [UIColor clearColor];UIButton *loginButton = [UIButton buttonWithType:UIButtonTypeSystem];[loginButton.layer setMasksToBounds:YES];[loginButton.layer setCornerRadius:5.0];[loginButton setBackgroundColor:[UIColor brownColor]];[loginButton setTitle:@"登陆" forState:UIControlStateNormal];[loginButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];[loginButton.titleLabel setFont:[UIFont systemFontOfSize:15]];[loginButton setTranslatesAutoresizingMaskIntoConstraints:NO];[loginButton addTarget:self action:@selector(loginBtnClick:) forControlEvents:UIControlEventTouchUpInside];//[footerView addSubview:btnExit];[footerView addSubview:loginButton];UIButton *registerButton = [UIButton buttonWithType:UIButtonTypeSystem];[registerButton.layer setMasksToBounds:YES];[registerButton.layer setCornerRadius:5.0];[registerButton setBackgroundColor:[UIColor brownColor]];[registerButton setTitle:@"注册" forState:UIControlStateNormal];[registerButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];[registerButton.titleLabel setFont:[UIFont systemFontOfSize:15]];[registerButton setTranslatesAutoresizingMaskIntoConstraints:NO];[registerButton addTarget:self action:@selector(registerBtnClick:) forControlEvents:UIControlEventTouchUpInside];[footerView addSubview:registerButton];NSDictionary *constraintsView = NSDictionaryOfVariableBindings(loginButton,registerButton);[footerView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-15-[loginButton]-15-|" options:0 metrics:nil views:constraintsView ]];[footerView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|-20-[loginButton]" options:0 metrics:nil views:constraintsView ]];[footerView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-15-[registerButton(==loginButton)]-15-|" options:0 metrics:nil views:constraintsView ]];[footerView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[loginButton]-30-[registerButton(==loginButton)]-20-|" options:0 metrics:nil views:constraintsView]];return footerView;}else{return nil;}}
