TableViewCell根據xcode中的內容自動調整其高度？

我需要根據它的內容設置tableViewCell的高度。我在tableViewCell中有一些動態高度的標籤，標籤中的行數不是恆定的。有時候，如果一個標籤的文本是null，那麼其他標籤可能佔據其位置。所以我需要的是tableViewCell應該根據內容高度autoresize？TableViewCell根據xcode中的內容自動調整其高度？

-(void)viewDidLoad 
{ 
self.tableView=[[UITableView alloc] initWithFrame:CGRectMake(0,150,327,[array count]*205) style:UITableViewStylePlain]; 
       self.tableView.delegate=self; 
       self.tableView.dataSource=self; 
       self.tableView.scrollEnabled = NO; 
       [self.view addSubview:self.tableView]; 

       float fscrview = 150 + self.tableView.frame.size.height + 20; 
       testscroll.contentSize=CGSizeMake(320, fscrview);

} 
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 

     return 1; 


} 
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { 
UIView *sectionHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, tableView.sectionHeaderHeight)]; 
    sectionHeaderView.backgroundColor = [UIColor colorWithWhite:0 alpha:0]; 
    sectionHeaderView.userInteractionEnabled = YES; 
    sectionHeaderView.tag = section; 


    UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(12,2, tableView.bounds.size.width-10, 18)]; 
    headerLabel.backgroundColor = [UIColor whiteColor]; 
    [headerLabel setTextAlignment:UITextAlignmentCenter]; 
    headerLabel.textColor = [UIColor grayColor]; 
    headerLabel.shadowColor = [UIColor darkGrayColor]; 
    headerLabel.shadowOffset = CGSizeMake(0, 1); 
    headerLabel.font = [UIFont boldSystemFontOfSize:18]; 
    headerLabel.text = @"Details"; 


    [sectionHeaderView addSubview:headerLabel]; 

    return sectionHeaderView; 
    }

在這裏，我給了它是205。但是當tableViewCell增加的文本，然後我無法看到的最後tableViewCell標籤的最後一行..

我怎樣才能讓tableViewCell到auto-resize它的高度？

我已編輯它。你可以看看，讓我知道在哪裏修改？ – Honey

您可以在– tableView:heightForRowAtIndexPath:中指定單元的高度。

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    CGFloat height=60; //set default row height 
    if(check_for_the_rows_which_need_increased_height) { 
     height+=50; //Add appropriate increase 
    } 
    return height; 
}

你需要調用[yourTableView reloadData]或[yourTableView reloadRowsAtIndexPaths:indexPath withRowAnimation:UITableViewRowAnimationAutomatic]用於上述方法再次調用。

我可以知道這是什麼嗎？ index_of_row_which_needs_increased_height – Honey

我已更新答案。將check_for_the_rows_which_need_increased_height替換爲你的條件來檢查哪些行應該增加高度 – Atif

但是我不知道哪一行need_increased_height bcoz所有的行以及它裏面的數據在運行時都會改變..所以我應該給那裏的check_for_the_rows_which_need_increased_height？ – Honey

您可以直接檢查你textHeight不同，然後設置你的行高

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath; 
{ 
    NSString *Yourtext = [yourTextAry objectAtIndex:[indexPath row]]; 

    CGSize constraint = CGSizeMake(yourLabelWidth , 20000.0f); 

    CGSize size = [Yourtext sizeWithFont: [UIFont fontWithName:@"Verdana" size:13] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; 

    CGFloat height = MAX(size.height, 44.0f); 

    return height; 
}

，如果文本爲空，然後從陣列中刪除它親愛的或只是通過高度爲零.. :)
