변경할 때 UITableView에 대한 reloadData에 애니메이션을 적용하십시오.

변경할 때 UITableView에 대한 reloadData에 애니메이션을 적용하십시오.

---

두 가지 모드가있는 UITableView가 있습니다. 모드 간을 전환하면 섹션마다 다른 수의 섹션과 셀이 있습니다. 이상적으로는 테이블이 커지거나 줄어들 때 멋진 애니메이션을 만듭니다.

여기에 내가 시도한 코드가 있지만 아무것도하지 않습니다.

CGContextRef context = UIGraphicsGetCurrentContext(); 
[UIView beginAnimations:nil context:context]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
[UIView setAnimationDuration:0.5]; 

[self.tableView reloadData];
[UIView commitAnimations];

내가 어떻게 할 수 있을지에 대한 생각?

---

실제로 매우 간단합니다.

[_tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade];

에서 문서 :

이 메소드를 호출하면 테이블보기가 데이터 소스에 지정된 섹션에 대한 새 셀을 요청합니다. 테이블 뷰는 기존 셀을 애니메이션 처리 할 때 새 셀 삽입을 애니메이션합니다.

다음을 사용할 수 있습니다.

목표 -C

[UIView transitionWithView: self.tableView
                  duration: 0.35f
                   options: UIViewAnimationOptionTransitionCrossDissolve
                animations: ^(void)
 {
      [self.tableView reloadData];
 }
                completion: nil];

빠른

UIView.transitionWithView(tableView,
                          duration: 0.35,
                          options: .TransitionCrossDissolve,
                          animations:
{ () -> Void in
    self.tableView.reloadData()
},
                          completion: nil);

스위프트 3

UIView.transition(with: tableView,
                  duration: 0.35,
                  options: .transitionCrossDissolve,
                  animations: { self.tableView.reloadData() }) // left out the unnecessary syntax in the completion block and the optional completion parameter

번거 로움이 없습니다. :디

CATransition수업을 통해 더 많은 자유를 누리십시오.

페이딩에만 국한되지는 않지만 움직임도 가능합니다.

---

예를 들면 다음과 같습니다.

(가져 오기를 잊지 마십시오 QuartzCore)

CATransition *transition = [CATransition animation];
transition.type = kCATransitionPush;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.fillMode = kCAFillModeForwards;
transition.duration = 0.5;
transition.subtype = kCATransitionFromBottom;

[[self.tableView layer] addAnimation:transition forKey:@"UITableViewReloadDataAnimationKey"];

등을 type필요에 맞게 변경하십시오 kCATransitionFade.

스위프트에서의 구현 :

let transition = CATransition()
transition.type = kCATransitionPush
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.fillMode = kCAFillModeForwards
transition.duration = 0.5
transition.subtype = kCATransitionFromTop
self.tableView.layer.addAnimation(transition, forKey: "UITableViewReloadDataAnimationKey")
// Update your data source here
self.tableView.reloadData()

CATransition에 대한 참조

스위프트 5 :

let transition = CATransition()
transition.type = CATransitionType.push
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.fillMode = CAMediaTimingFillMode.forwards
transition.duration = 0.5
transition.subtype = CATransitionSubtype.fromTop
self.tableView.layer.add(transition, forKey: "UITableViewReloadDataAnimationKey")
// Update your data source here
self.tableView.reloadData()

데이터 구조를 업데이트하면 다음과 같습니다.

[tableView beginUpdates];
[tableView deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES];
[tableView insertSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES];
[tableView endUpdates];

또한 "withRowAnimation"은 부울이 아니라 애니메이션 스타일입니다.

UITableViewRowAnimationFade,
UITableViewRowAnimationRight,
UITableViewRowAnimationLeft,
UITableViewRowAnimationTop,
UITableViewRowAnimationBottom,
UITableViewRowAnimationNone,
UITableViewRowAnimationMiddle

이 모든 답변은 하나의 섹션으로 UITableView를 사용한다고 가정합니다.

섹션이 두 개 이상인 상황을 정확하게 처리하려면 다음을 사용하십시오.

NSRange range = NSMakeRange(0, myTableView.numberOfSections);
NSIndexSet *indexSet = [NSIndexSet indexSetWithIndexesInRange:range];
[myTableView reloadSections:indexSet withRowAnimation:UITableViewRowAnimationAutomatic];

(참고 : 섹션이 0 개 이상 있는지 확인해야합니다!)

이 코드로 데이터 소스를 동시에 업데이트하려고하면 NSInternalInconsistencyException이 발생할 수 있습니다. 이 경우 다음과 유사한 논리를 사용할 수 있습니다.

int sectionNumber = 0; //Note that your section may be different

int nextIndex = [currentItems count]; //starting index of newly added items

[myTableView beginUpdates];

for (NSObject *item in itemsToAdd) {
    //Add the item to the data source
    [currentItems addObject:item];

    //Add the item to the table view
    NSIndexPath *path = [NSIndexPath indexPathForRow:nextIndex++ inSection:sectionNumber];
    [myTableView insertRowsAtIndexPaths:[NSArray arrayWithObject:path] withRowAnimation:UITableViewRowAnimationAutomatic];
}

[myTableView endUpdates];

---

The way to approach this is to tell the tableView to remove and add rows and sections with the

insertRowsAtIndexPaths:withRowAnimation:, deleteRowsAtIndexPaths:withRowAnimation:, insertSections:withRowAnimation: and deleteSections:withRowAnimation:

methods of UITableView. When you call these methods, the table will animate in/out the items you requested, then call reloadData on itself so you can update the state after this animation. This part is important - if you animate away everything but don't change the data returned by the table's dataSource, the rows will appear again after the animation completes.

So, your application flow would be:

[self setTableIsInSecondState:YES];

[myTable deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES]];

As long as your table's dataSource methods return the correct new set of sections and rows by checking [self tableIsInSecondState] (or whatever), this will achieve the effect you're looking for.

I can't comment on the top answer, but a swift implementation would be:

self.tableView.reloadSections([0], with: UITableViewRowAnimation.fade)

you could include as many sections as you want to update in the first argument for reloadSections.

Other animations available from the docs: https://developer.apple.com/reference/uikit/uitableviewrowanimation

fade The inserted or deleted row or rows fade into or out of the table view.

right The inserted row or rows slide in from the right; the deleted row or rows slide out to the right.

left The inserted row or rows slide in from the left; the deleted row or rows slide out to the left.

top The inserted row or rows slide in from the top; the deleted row or rows slide out toward the top.

bottom The inserted row or rows slide in from the bottom; the deleted row or rows slide out toward the bottom.

case none The inserted or deleted rows use the default animations.

middle The table view attempts to keep the old and new cells centered in the space they did or will occupy. Available in iPhone 3.2.

automatic The table view chooses an appropriate animation style for you. (Introduced in iOS 5.0.)

Swift 4 version for @dmarnel answer:

tableView.reloadSections(IndexSet(integer: 0), with: .automatic)

---

Swift Implementation:

let range = NSMakeRange(0, self.tableView!.numberOfSections())
let indexSet = NSIndexSet(indexesInRange: range)
self.tableView!.reloadSections(indexSet, withRowAnimation: UITableViewRowAnimation.Automatic)

---

For Swift 4

tableView.reloadSections([0], with: UITableView.RowAnimation.fade)

---

In my case, I wanted to add 10 more rows into the tableview (for a "show more results" type of functionality) and I did the following:

  NSInteger tempNumber = self.numberOfRows;
  self.numberOfRows += 10;
  NSMutableArray *arrayOfIndexPaths = [[NSMutableArray alloc] init];
  for (NSInteger i = tempNumber; i < self.numberOfRows; i++) {
    [arrayOfIndexPaths addObject:[NSIndexPath indexPathForRow:i inSection:0]];
  }
  [self.tableView beginUpdates];
  [self.tableView insertRowsAtIndexPaths:arrayOfIndexPaths withRowAnimation:UITableViewRowAnimationTop];
  [self.tableView endUpdates];

In most cases, instead of "self.numberOfRows", you would usually use the count of the array of objects for the tableview. So to make sure this solution works well for you, "arrayOfIndexPaths" needs to be an accurate array of the index paths of the rows being inserted. If the row exists for any of this index paths, the code might crash, so you should use the method "reloadRowsAtIndexPaths:withRowAnimation:" for those index pathds to avoid crashing

---

If you want to add your own custom animations to UITableView cells, use

[theTableView reloadData];
[theTableView layoutSubviews];
NSArray* visibleViews = [theTableView visibleCells];

to get an array of visible cells. Then add any custom animation to each cell.

Check out this gist I posted for a smooth custom cell animation. https://gist.github.com/floprr/1b7a58e4a18449d962bd

Animating without reloadData() in Swift can be done like this (as of version 2.2):

tableview.beginUpdates()
var indexPathsToDeleteForAnimation: [NSIndexPath] = []
var numOfCellsToRemove = ArrayOfItemsToRemove ?? 0

// Do your work here
while numOfCellsToRemove > 0 {
    // ...or here, if you need to add/remove the same amount of objects to/from somewhere
    indexPathsToDeleteForAnimation.append(NSIndexPath(forRow: selectedCellIndex+numOfCellsToRemove, inSection: 0))
    numOfCellsToRemove -= 1
}
tableview.deleteRowsAtIndexPaths(indexPathsToDeleteForAnimation, withRowAnimation: UITableViewRowAnimation.Right)
tableview.endUpdates()

in case you need to call reloadData() after the animation ends, you can embrace the changes in CATransaction like this:

CATransaction.begin()
CATransaction.setCompletionBlock({() in self.tableview.reloadData() })
tableview.beginUpdates()
var indexPathsToDeleteForAnimation: [NSIndexPath] = []
var numOfCellsToRemove = ArrayOfItemsToRemove.count ?? 0

// Do your work here
while numOfCellsToRemove > 0 {
     // ...or here, if you need to add/remove the same amount of objects to/from somewhere
     indexPathsToDeleteForAnimation.append(NSIndexPath(forRow: selectedCellIndex+numOfCellsToRemove, inSection: 0))
     numOfCellsToRemove -= 1
}
tableview.deleteRowsAtIndexPaths(indexPathsToDeleteForAnimation, withRowAnimation: UITableViewRowAnimation.Right)
tableview.endUpdates()
CATransaction.commit()

The logic is shown for the case when you delete rows, but the same idea works also for adding rows. You can also change animation to UITableViewRowAnimation.Left to make it neat, or choose from the list of other available animations.

CATransition *animation = [CATransition animation];
animation.duration = .3;
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[animation setDuration:.3];

[[_elementTableView layer] addAnimation:animation forKey:@"UITableViewReloadDataAnimationKey"];

[tableView reloadData];

---

To reload all sections, not just one with custom duration.

User duration parameter of UIView.animate to set custom duration.

UIView.animate(withDuration: 0.4, animations: { [weak self] in
    guard let `self` = self else { return }
    let indexSet = IndexSet(integersIn: 0..<self.tableView.numberOfSections)
    self.tableView.reloadSections(indexSet, with: UITableView.RowAnimation.fade)
})
