UI基础--封装cell滑动时的动画

新建一个类:CellDisplay:NSObject

.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface CellDisplay : NSObject

+(void)tableView:(UITableView *)tableView cell:(UITableViewCell *)cell IndexPath:(NSIndexPath *)indexPath;

@end

.m

#import "CellDisplay.h"

@implementation CellDisplay

+(void)tableView:(UITableView *)tableView cell:(UITableViewCell *)cell IndexPath:(NSIndexPath *)indexPath
{

    NSArray *array =  tableView.indexPathsForVisibleRows;
    NSIndexPath *firstIndexPath = array[0];

    //设置anchorPoint
    cell.layer.anchorPoint = CGPointMake(0, 0.5);
    //为了防止cell视图移动，重新把cell放回原来的位置
    cell.layer.position = CGPointMake(0, cell.layer.position.y);

    //设置cell 按照z轴旋转90度，注意是弧度
    if (firstIndexPath.row < indexPath.row) {
        cell.layer.transform = CATransform3DMakeRotation(M_PI_2, 0, 0, 1.0);
    }else{
        cell.layer.transform = CATransform3DMakeRotation(- M_PI_2, 0, 0, 1.0);
    }

    cell.alpha = 0.0;

    [UIView animateWithDuration:1 animations:^{
        cell.layer.transform = CATransform3DIdentity;
        cell.alpha = 1.0;
    }];

    //CollectionCell 动画
    /*
     if (indexPath.row % 2 != 0) {
     cell.transform = CGAffineTransformTranslate(cell.transform, kScreenWidth/2, 0);
     }else{
     cell.transform = CGAffineTransformTranslate(cell.transform, -kScreenWidth/2, 0);
     }
     cell.alpha = 0.0;
     [UIView animateWithDuration:0.7 animations:^{
     cell.transform = CGAffineTransformIdentity;
     cell.alpha = 1.0;
     } completion:^(BOOL finished) {

     }];
     */

}

@end

在tableview的协议方法中调用即可:

- (void)tableView:(UITableView *)tableView willDisplayCell:(nonnull UITableViewCell *)cell forRowAtIndexPath:(nonnull NSIndexPath *)indexPath
{

    [CellDisplay tableView:tableView cell:cell IndexPath:indexPath];

}

Ok...
