UILabel positions not adjusting when superview changes size
2
I am pretty new to iOS and Objective-C.
I have been trying to get a programmatically generated UITableView to work correctly. The table uses a custom UITableViewCell that is in it's own xib file, MeetingsTableViewCell.
Here is how the .xib looks:
And the constraints for the date field:
Here is how it looks when run:
The date and Meeting Mode icon/label are 55 points(?) too far to the right in the simulation.
The main view controller has a width of 320 (I don't seem to be able to change that). The .xib has a width of 375 (I don't seem to be able to change that either). 55 points. Coincidence? I am guessing not.
When I used debug view hierarchy, I discovered that the Cell Wrapper View was 375 points. I added the following code (perhaps more than needed, but I was just trying everything to see if I could figure it out):
cell.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
cell.autoresizesSubviews = true;
cell.cellWrapperView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
cell.cellWrapperView.autoresizesSubviews = true;
I also made sure that I had layoutIfNeeded in the MeetingsTableCellView.m file and added code to resize cellWrapperView
-(void)layoutIfNeeded
[super layoutIfNeeded];
self.cellWrapperView.frame=self.contentView.bounds;
That resized the views correctly to 320, but didn't move the date and meeting mode icon/label.
The debug view now looks like this:
The TableCellView and every full-width thing inside it are 320 points wide. The date and meetings mode icon/label are (correctly) 68 points wide according to debug view. The X position is 297. I do not know how to get the date and meetings mode icon/label to be in the correct position.
As a side note, if I turn the phone to landscape, those widths are all 375 instead of 320, but shouldn't they be 568 now?
Thanks!
EDIT: The code that creates the table.
self.meetings=meetings;
self.meetingsTable=[[UITableView alloc] initWithFrame:self.tableWrapperView.bounds];
self.meetingsTable.delegate = self;
self.meetingsTable.dataSource = self;
self.meetingsTable.autoresizesSubviews = true;
self.meetingsTable.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.tableWrapperView.autoresizesSubviews = true;
UINib *cellNib=[UINib nibWithNibName:@"MeetingCellView" bundle:nil];
[self.meetingsTable registerNib:cellNib forCellReuseIdentifier:@"MeetingsCell"];
[self.meetingsTable reloadData];
[self.tableWrapperView addSubview:self.meetingsTable];

I think you're over-complicating things a bit.
For one, you don't need the "cellWrapperView" -- it's serving no purpose that the contentView can't do.
Second, for cell layout, you shouldn't need any code in your cell class.
I did a quick test, laying out the cell (approximately) as you have:
and here are the results (I frequently use background colors to help see the element frames):
That is accomplished with only this code...
//
// MeetingsTableViewCell.h
//
#import <UIKit/UIKit.h>
@interface MeetingsTableViewCell : UITableViewCell
@property (strong, nonatomic) IBOutlet UILabel *theTitleLabel;
@property (strong, nonatomic) IBOutlet UILabel *theSubTitleLabel;
@property (strong, nonatomic) IBOutlet UILabel *theDateLabel;
@property (strong, nonatomic) IBOutlet UIImageView *theImageView;
@property (strong, nonatomic) IBOutlet UILabel *theModeLabel;
@end
//
// MeetingsTableViewCell.m
//
#import "MeetingsTableViewCell.h"
@implementation MeetingsTableViewCell
@end
//
// TableXIBViewController.h
//
#import <UIKit/UIKit.h>
@interface TableXIBViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
@end
//
// TableXIBViewController.m
//
// Created by Don Mag on 11/14/18.
//
#import "TableXIBViewController.h"
#import "MeetingsTableViewCell.h"
@interface TableXIBViewController ()
@property UITableView *meetingsTable;
@property UIView *tableWrapperView;
@end
@implementation TableXIBViewController
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor redColor];
// inset the table wrapper view by 20-pts so we can see its frame
self.tableWrapperView = [[UIView alloc] initWithFrame:CGRectInset(self.view.frame, 20, 20)];
self.tableWrapperView.autoresizingMask = UIViewAutoresizingFlexibleWidth
- (nonnull UITableViewCell *)tableView:(nonnull UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath
MeetingsTableViewCell *cell = [self.meetingsTable dequeueReusableCellWithIdentifier:@"MeetingsCell" forIndexPath:indexPath];
cell.theTitleLabel.text = [NSString stringWithFormat:@"Meeting Title %li", indexPath.row + 1];
cell.theSubTitleLabel.text = [NSString stringWithFormat:@"Meeting SubTitle %li", indexPath.row + 1];
cell.theDateLabel.text = [NSString stringWithFormat:@"2018/01/0%li", indexPath.row + 1];
return cell;
- (NSInteger)tableView:(nonnull UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return 5;

i started out minimally, all of the things got added as ways to try and resolve the problem. I will go back to the minimal version and compare it to what you have to see if I can find the difference
– Ben Holness
Nov 14 '18 at 20:54
I found the difference. I had originally gone file -> new, chosen view and XCode put aUITableViewCellinside of it. I noticed that your xib view was table cell sized and mine wasn't (you can kind of see it in my first screenshot). I moved it up to the top level and deleted theUIViewand now it works. Thanks!

i started out minimally, all of the things got added as ways to try and resolve the problem. I will go back to the minimal version and compare it to what you have to see if I can find the difference
– Ben Holness

I found the difference. I had originally gone file -> new, chosen view and XCode put aUITableViewCellinside of it. I noticed that your xib view was table cell sized and mine wasn't (you can kind of see it in my first screenshot). I moved it up to the top level and deleted theUIViewand now it works. Thanks!

I think you're over-complicating things a bit.
For one, you don't need the "cellWrapperView" -- it's serving no purpose that the contentView can't do.
Second, for cell layout, you shouldn't need any code in your cell class.
I did a quick test, laying out the cell (approximately) as you have:
and here are the results (I frequently use background colors to help see the element frames):
That is accomplished with only this code...
//
// MeetingsTableViewCell.h
//
#import <UIKit/UIKit.h>
@interface MeetingsTableViewCell : UITableViewCell
@property (strong, nonatomic) IBOutlet UILabel *theTitleLabel;
@property (strong, nonatomic) IBOutlet UILabel *theSubTitleLabel;
@property (strong, nonatomic) IBOutlet UILabel *theDateLabel;
@property (strong, nonatomic) IBOutlet UIImageView *theImageView;
@property (strong, nonatomic) IBOutlet UILabel *theModeLabel;
@end
//
// MeetingsTableViewCell.m
//
#import "MeetingsTableViewCell.h"
@implementation MeetingsTableViewCell
@end
//
// TableXIBViewController.h
//
#import <UIKit/UIKit.h>
@interface TableXIBViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
@end
//
// TableXIBViewController.m
//
// Created by Don Mag on 11/14/18.
//
#import "TableXIBViewController.h"
#import "MeetingsTableViewCell.h"
@interface TableXIBViewController ()
@property UITableView *meetingsTable;
@property UIView *tableWrapperView;
@end
@implementation TableXIBViewController
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor redColor];
// inset the table wrapper view by 20-pts so we can see its frame
self.tableWrapperView = [[UIView alloc] initWithFrame:CGRectInset(self.view.frame, 20, 20)];
self.tableWrapperView.autoresizingMask = UIViewAutoresizingFlexibleWidth
- (nonnull UITableViewCell *)tableView:(nonnull UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath
MeetingsTableViewCell *cell = [self.meetingsTable dequeueReusableCellWithIdentifier:@"MeetingsCell" forIndexPath:indexPath];
cell.theTitleLabel.text = [NSString stringWithFormat:@"Meeting Title %li", indexPath.row + 1];
cell.theSubTitleLabel.text = [NSString stringWithFormat:@"Meeting SubTitle %li", indexPath.row + 1];
cell.theDateLabel.text = [NSString stringWithFormat:@"2018/01/0%li", indexPath.row + 1];
return cell;
- (NSInteger)tableView:(nonnull UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return 5;
@end

I think you're over-complicating things a bit.
For one, you don't need the "cellWrapperView" -- it's serving no purpose that the contentView can't do.
Second, for cell layout, you shouldn't need any code in your cell class.
I did a quick test, laying out the cell (approximately) as you have:
and here are the results (I frequently use background colors to help see the element frames):
That is accomplished with only this code...
//
// MeetingsTableViewCell.h
//
#import <UIKit/UIKit.h>
@interface MeetingsTableViewCell : UITableViewCell
@property (strong, nonatomic) IBOutlet UILabel *theTitleLabel;
@property (strong, nonatomic) IBOutlet UILabel *theSubTitleLabel;
@property (strong, nonatomic) IBOutlet UILabel *theDateLabel;
@property (strong, nonatomic) IBOutlet UIImageView *theImageView;
@property (strong, nonatomic) IBOutlet UILabel *theModeLabel;
@end
//
// MeetingsTableViewCell.m
//
#import "MeetingsTableViewCell.h"
@implementation MeetingsTableViewCell
@end
//
// TableXIBViewController.h
//
#import <UIKit/UIKit.h>
@interface TableXIBViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
@end
//
// TableXIBViewController.m
//
// Created by Don Mag on 11/14/18.
//
#import "TableXIBViewController.h"
#import "MeetingsTableViewCell.h"
@interface TableXIBViewController ()
@property UITableView *meetingsTable;
@property UIView *tableWrapperView;
@end
@implementation TableXIBViewController
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor redColor];
// inset the table wrapper view by 20-pts so we can see its frame
self.tableWrapperView = [[UIView alloc] initWithFrame:CGRectInset(self.view.frame, 20, 20)];
self.tableWrapperView.autoresizingMask = UIViewAutoresizingFlexibleWidth
- (nonnull UITableViewCell *)tableView:(nonnull UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath
MeetingsTableViewCell *cell = [self.meetingsTable dequeueReusableCellWithIdentifier:@"MeetingsCell" forIndexPath:indexPath];
cell.theTitleLabel.text = [NSString stringWithFormat:@"Meeting Title %li", indexPath.row + 1];
cell.theSubTitleLabel.text = [NSString stringWithFormat:@"Meeting SubTitle %li", indexPath.row + 1];
cell.theDateLabel.text = [NSString stringWithFormat:@"2018/01/0%li", indexPath.row + 1];
return cell;
- (NSInteger)tableView:(nonnull UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return 5;
@end
And, to help get the cell xib laid-out correctly, here is the xib source:

i started out minimally, all of the things got added as ways to try and resolve the problem. I will go back to the minimal version and compare it to what you have to see if I can find the difference

I found the difference. I had originally gone file -> new, chosen view and XCode put aUITableViewCellinside of it. I noticed that your xib view was table cell sized and mine wasn't (you can kind of see it in my first screenshot). I moved it up to the top level and deleted theUIViewand now it works. Thanks!
