短视频系统,折叠cell的使用实现的相关代码
完整代码如下:
@property (nonatomic, strong) UITableView* foldTableView; @property (nonatomic, strong) NSMutableArray* foldArray; @property (nonatomic, strong) UIButton* foldButton; - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor whiteColor]; _foldTableView = [[UITableView alloc] initWithFrame:CGRectMake(10, 100, 380, 50) style:UITableViewStylePlain]; _foldTableView.delegate = self; _foldTableView.dataSource = self; [self.view addSubview:_foldTableView]; [_foldTableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"normal"]; _foldArray = [NSMutableArray arrayWithObjects:@"内容1", @"内容2", @"内容3", @"内容4", @"内容5", @"内容6", @"内容7", nil]; _foldButton = [UIButton buttonWithType:UIButtonTypeCustom]; [_foldButton.layer setMasksToBounds:YES]; [_foldButton.layer setCornerRadius:15.0]; [_foldButton setTitle:@"点击展开" forState:UIControlStateNormal]; [_foldButton setTitle:@"点击收起" forState:UIControlStateSelected]; [_foldButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [_foldButton setTitleColor:[UIColor blackColor] forState:UIControlStateSelected]; _foldButton.backgroundColor = [UIColor yellowColor]; _foldButton.titleLabel.font = [UIFont systemFontOfSize:20]; [_foldButton addTarget:self action:@selector(pressFoldButton:) forControlEvents:UIControlEventTouchUpInside]; _foldButton.frame = CGRectMake(0, 0, 380, 50); } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return _foldArray.count; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 50; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell* normalCell = [_foldTableView dequeueReusableCellWithIdentifier:@"normal" forIndexPath:indexPath]; [normalCell.layer setMasksToBounds:YES]; [normalCell.layer setCornerRadius:15.0]; if (indexPath.row == 0) { [normalCell.contentView addSubview:_foldButton]; } else { normalCell.textLabel.text = _foldArray[indexPath.row - 1]; normalCell.textLabel.textColor = [UIColor blackColor]; normalCell.textLabel.textAlignment = NSTextAlignmentCenter; normalCell.textLabel.font = [UIFont systemFontOfSize:20]; normalCell.backgroundColor = [UIColor yellowColor]; } return normalCell; } - (void)pressFoldButton:(UIButton*)button { if (button.selected == YES) { button.selected = NO; _foldTableView.frame = CGRectMake(10, 100, 380, 50); } else if (button.selected == NO) { button.selected = YES; _foldTableView.frame = CGRectMake(10, 100, 380, 50 * _foldArray.count); } }
