ios - 在 IOS 8 中使用自动布局调整单元格大小

Question

我曾尝试使用内容大小调整单元格大小，但我了解到在 IOS 8 中您可以使用自动版式调整单元格大小。我尝试了同样的方法，但无法获得确切的用户界面。我在 UIView Controller 中有一个 TableView。这是我的代码 viewcontroller.m :-

@implementation MessageViewController
@synthesize  messageTable;
- (void)viewDidLoad {
    self.messageTable.estimatedRowHeight = 70.0;
    self.messageTable.rowHeight = UITableViewAutomaticDimension;

   [super viewDidLoad];


  if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
      self.edgesForExtendedLayout = UIRectEdgeNone;
  self.navigationController.toolbarHidden=NO;
  _txtField=[[UITextView alloc] initWithFrame:CGRectMake(40, 5, 220, 30)];
  [_txtField setFont:[UIFont systemFontOfSize:15]];
  _txtField.layer.cornerRadius = 7.0;
  _txtField.clipsToBounds = YES;

  _txtField.text=@"Hello";



[self.navigationController.toolbar addSubview:_txtField];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setTitle:@"Send" forState:UIControlStateNormal];
button.frame = CGRectMake(265.0, 5, 50.0, 30.0);

[self.navigationController.toolbar addSubview:button];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]

                               initWithTarget:self
                               action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];


// table view data is being set here
_messageArray = [[NSMutableArray alloc]initWithObjects:
           @"Data 2 ",@"Data 1 Data 1Data 1Data 1Data 1Data 1Data 1Data     1Data 1D",@"Data 8 ",
               @"Data 9 ", nil];
     [self.messageTable reloadData];

// Do any additional setup after loading the view.
}

http://www.appcoda.com/self-sizing-cells/ 您可以尝试此链接以仅在 iOS 8 中自动调整标签大小。

并且不要忘记在您的 viewdidload 中添加以下行。

tableView.estimatedRowHeight = 44.0
tableView.rowHeight = UITableViewAutomaticDimension
