uitableviewcell does not fit well on the ipad

Well, it's the typical example of autolayout. You have to define your position with respect to the rest of the items. You can do it using a .xib or by hand. The textlabel is positioned correctly by the cell by default, but the image must be placed by you. To do that by hand you have to:

• First thing, you do not need to position the button. If you do, I will draw it in the coordinates that you indicate. Create the centroactivo only with size, without position

  centroActivo.frame = CGRectMake(0.0, 0.0, 20.0f, 20.0f);
  

• You have to put translatesAutoresizingMaskIntoConstraints to NO to be able to put constraints at hand

  centroActivo.translatesAutoresizingMaskIntoConstraints = NO;
  

• Then you have to add centroActivo to the view (the cell in this case)

• Finally add constraints to indicate where to position it. Here is the butter. You have to give the necessary positions so that iOS knows where to draw. In this case, I think that by indicating that it is at x points on the left margin (for example 15) and that it is centered on the cell, it would be enough.

  NSlayoutConstraint *trailing = [NSLayoutContraint 
                               constraintWithItem: centroActivo
                               attribute:NSLayoutAttributeTrailing
                               relatedBy: NSLayoutRelationEqual
                               toItem: self.contentView
                               attribute: NSLayoutAttributeTrailing
                               multiplier: 1.0f
                               constant: 15.f];
  NSlayoutConstraint *center = [NSLayoutConstraint constraintWithItem:centroActivo attribute:NSLayoutAttributeCenterX
                               relatedBy:NSLayoutRelationEqual                                                             
                                  toItem:self.contentView
                               attribute:NSLayoutAttributeCenterX 
                              multiplier:1 
                                constant:0];
  
  
  [self.contentView addConstraint:trailing];
  [self.contentView addConstraint:center];
  

So the lines where with orientation tests and if it's iPad would remove them and only leave the frame of the centerActive All this outside: int orientation = [[UIApplication sharedApplication] statusBarOrientation];

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad || (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone && orientation != UIDeviceOrientationPortrait)) {
    centroActivo.frame = CGRectMake(350.0, 15.0f, 20.0f, 20.0f);
} else {
    centroActivo.frame = CGRectMake(290.0, 15.0f, 20.0f, 20.0f);
}

and would only leave the

centroActivo.frame = CGRectMake(0.0, .0f, 20.0f, 20.0f);

TextLabel overlaps

Well, for this case we have to do something similar. Tell him where he has to paint it So the first thing is to tell him that you are going to touch the constraints

    cell.textLabel.translatesAutoresizingMaskIntoConstraints = NO;

And then as with the centerActive add the constraints. In this case we are going to give him a left one of about 15 points, we will center him with respect to the cell and we will tell him that he has to be another 15 points away from the centerActivo.

    //esto es la derecha, así que se relaciona con centroActivo
    NSlayoutConstraint *trailingText = [NSLayoutContraint 
                         constraintWithItem: cell.textLabel
                         attribute:NSLayoutAttributeTrailing
                         relatedBy: NSLayoutRelationEqual
                         toItem: centroActivo
                         attribute: NSLayoutAttributeTrailing
                         multiplier: 1.0f
                         constant: 15.f];
    NSlayoutConstraint *centerText = [NSLayoutConstraint     constraintWithItem:cell.textLabel
                         attribute:NSLayoutAttributeCenterX
                         relatedBy:NSLayoutRelationEqual                                                             
                            toItem:self.contentView
                         attribute:NSLayoutAttributeCenterX 
                        multiplier:1 
                          constant:0];
    //esto es con el margen izquierdo
    NSlayoutConstraint *leadingText = [NSLayoutContraint 
                         constraintWithItem: cell.textLabel
                         attribute:NSLayoutAttributeLeading
                         relatedBy: NSLayoutRelationEqual
                         toItem: self.contentView
                         attribute: NSLayoutAttributeTrailing
                         multiplier: 1.0f
                         constant: 15.f];

    [self.contentView addConstraint:leadingText];
    [self.contentView addConstraint:trailingText];
    [self.contentView addConstraint:centerText];

I hope it serves you, the ObjC I already have it a little forgotten

This is due to not using or incorrectly using AutoLayout . You must create some constraints that leave the checkbox to the right. Then, the right constraint of the UILabel should always be "stuck" to the left side of the checkbox.

It's complicated to explain here, but basically it's a problem of AutoLayout
