具體代碼如下:

#import "ViewController.h"

@interface ViewController ()<UITableViewDelegate,UITableViewDataSource>
@property(nonatomic,strong)UITableView *myTableV;
@property(nonatomic,strong)NSArray *contentAry;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
// Do any additional setup after loading the view, typically from a nib. self.contentAry = [NSArray array]; [self creatUI]; } - (IBAction)leftAction:(id)sender { self.contentAry = self.myTableV.visibleCells; NSLog(@"----%@",self.contentAry); UIButton *button = (UIButton*)sender; button.selected
= !button.selected; CGAffineTransform transform; double duration = 0.1; if (button.tag == 1) { transform = CGAffineTransformMakeTranslation(-[UIScreen mainScreen].bounds.size.width, 0); }else if (button.tag == 2) { for (UITableViewCell *cell in self.contentAry) { [UIView animateWithDuration:duration delay:
0 options:0 animations:^{ cell.transform = CGAffineTransformIdentity; } completion:^(BOOL finished) { }]; duration += 0.1; } return; }else { transform = CGAffineTransformMakeTranslation([UIScreen mainScreen].bounds.size.width, 0); } for (UITableViewCell *cell in self.contentAry) { [UIView animateWithDuration:duration delay:0 options:0 animations:^{ cell.transform = transform; } completion:^(BOOL finished) { }]; duration += 0.1; } } -(void)creatUI { self.myTableV = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height - 100) style:UITableViewStylePlain]; self.myTableV.delegate = self; self.myTableV.dataSource = self; self.myTableV.tableFooterView = [[UIView alloc]init]; [self.view addSubview:self.myTableV]; } -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 5; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *celliden = @"CELLS"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:celliden]; if (!cell) { cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:celliden]; } cell.textLabel.text = [NSString stringWithFormat:@"%ld",(long)indexPath.row]; cell.backgroundColor = [[UIColor blackColor]colorWithAlphaComponent:0.6]; return cell; }

僅做記錄!
