UITableViewCell向上移动自定义segue出现/关闭

Question

我有一个MasterViewController，使用自定义模态segue，呈现一个详细视图。自定义模态动画是来自GitHub上mluisbrown的LCZoomTransition。目前，我遇到了一个问题，导致我的tableview的单元格在选择时向上移动。

我不知道是什么原因造成这种情况。我的代码提交详细视图：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 

    EditViewController *edit = [[EditViewController alloc]init]; 

    NSManagedObjectContext *mo = [_fetchedResultsController objectAtIndexPath:indexPath]; 
    [edit setManagedObjectContext:mo]; 



    id appDelegate= [[UIApplication sharedApplication] delegate]; 
    self.managedObjectContext = [appDelegate managedObjectContext]; 


    OweInfo *info = [_fetchedResultsController objectAtIndexPath:indexPath]; 

    self.editView = edit; 


    self.editView.delegate = self; 
    self.editView.info = info; 

    edit.info = info; 
    edit.delegate = self; 
    edit.managedObjectContext = [appDelegate managedObjectContext]; 



    self.editView.managedObjectContext = [appDelegate managedObjectContext]; 
[self performSegueWithIdentifier:@"pushToEdit" sender:self]; 



} 

和我赛格瑞代码：

if([segue.identifier isEqual: @"pushToEdit"]){ 


     NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; 
     self.zoomTransition.sourceView = [self.tableView cellForRowAtIndexPath:indexPath]; 
       // pass the custom transition to the destination controller 
     // so it can use it when setting up its gesture recognizers 
     [[segue destinationViewController] setGestureTarget:self.zoomTransition]; 
    EditViewController *edit = segue.destinationViewController; 

     NSManagedObjectContext *mo = [_fetchedResultsController objectAtIndexPath:indexPath]; 
     [edit setManagedObjectContext:mo]; 


     id appDelegate= [[UIApplication sharedApplication] delegate]; 
     self.managedObjectContext = [appDelegate managedObjectContext]; 


     OweInfo *info = [_fetchedResultsController objectAtIndexPath:indexPath]; 
      self.editView = edit; 


     self.editView.delegate = self; 
     self.editView.info = info; 
    self.editView.managedObjectContext = self.managedObjectContext; 
    edit.managedObjectContext = self.managedObjectContext; 

     edit.info = info; 
     edit.delegate = self; 





    } 

任何人都知道可能会导致什么呢？这是在iOS 8和Xcode的6

什么是应该的样子：

Answer 1

在我看来，你是复制多个控制器。

在didSelectRowAtIndexPath应该包含调用segue。

然后只创建一个实例的viewController

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
    [self performSegueWithIdentifier:@"pushToEdit" sender:self]; 
} 

就是这样的，你做的SEGUE委托休息，避免重复实例。
