解决方案，给input输入框添加一个指令，这个指令用来监听input的onFocus事件，只要触发这个事件，就计算input的top和当前页面滚动的top，从而计算出实际的top，然后控制页面滚动。
.directive('focusInput', ['$ionicScrollDelegate', '$window', '$timeout', '$ionicPosition', function ($ionicScrollDelegate, $window, $timeout, $ionicPosition) {
return {
restrict: 'A',
scope: false,
link: function ($scope, iElm, iAttrs, controller) {
if (ionic.Platform.isIOS()) {
iElm.on('focus', function () {
var top = $ionicScrollDelegate.getScrollPosition().top;
var eleTop = ($ionicPosition.offset(iElm).top) / 2
var realTop = eleTop + top;
$timeout(function () {
if (!$scope.$last) {
$ionicScrollDelegate.scrollTo(0,realTop);
} else {
try {
var aim = angular.element(document).find('.scroll')
aim.css('transform', 'translate3d(0px,' + '-' + realTop + 'px, 0px) scale(1)');
$timeout(function () {
iElm[0].focus();
console.log(2);
}, 100)
} catch (e) {
}
}
}, 500)
})
}
}
}
}])
