#Installation

`pod 'UITableViewController+KYSelfSizingPushFix', '~> 1.0.0'`

##How to use

###Three Steps：

**1.Add code in `- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath`**

```objective-c

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    ...

    

    if (![self ky_isEstimatedRowHeightInCache:indexPath]) {

        CGSize cellSize = [cell systemLayoutSizeFittingSize:CGSizeMake(self.view.frame.size.width, 0) withHorizontalFittingPriority:1000.0 verticalFittingPriority:50.0];

        [self ky_putEstimatedCellHeightToCache:indexPath height:cellSize.height];

    }

    

    ...

}

```

**2.Implement `estimatedHeightForRowAtIndexPath:`：**

```objective-c

-(CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {

    return [self ky_getEstimatedCellHeightFromCache:indexPath defaultHeight:250.0f];

}

```

**3.Remember to use` [self ky_tableViewReloadData];` rather than `[self.tableView reloadData];`**
