For group table cell, I fall into this problem.
cell.backgroundColor=[UIColor clearColor]
make the cell bg black. It works for normal cell, not for group table cell.
I want to add some button, e.g. like the detail view of iPhone contact with transparent background.
If anybody face the problem, I got a solution, set a transparent view as a background view of the cell. Then it becomes totally transparent. Then you can add more view or customize the cell.
UIView *backView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
backView.backgroundColor = [UIColor clearColor];
messageCell.backgroundView = backView;
messageCell.contentView.layer.cornerRadius = 10.0;
messageCell.contentView.layer.borderWidth = 1.0f;
messageCell.contentView.layer.borderColor = [[Settings getInstance] colorFrameBorder].CGColor;
messageCell.selectionStyle = UITableViewCellSelectionStyleNone;
return messageCell;
This solution was quoted in one of the StackOverflow question, which I cant remember.
I have also found that, its easy to add a transparent view in the table header or footer. The button down the contact details are probably added in a footer view.
From the looks of it I'd say you are setting a background image to your cell. You can see it at each cell on the right side, there are the stripes from your view background.
Remove the cell's background and you should be fine.
I found the solution from this answer here by setting cell's backgroundView
cell.backgroundView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
I would take Charles's answer one step further and do the following
self.myTableView.backgroundView = [[UIView alloc] initWithFrame:CGRectZero];

I'm setting the backgroundView of a tableView like this:
self.tableView.backgroundView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"background"]];
It works but gets placed on top of the tableview's activity indicator and hides it when the tableview is pulled down for refresh. I've tried setting a breakpoint on the point it's added and confirmed that indeed it goes on top of the activity indicator subviews array. Is there any way to fix this?
Thanks in advance.
I suggest that is better to place UIImageView below your UITableView and set:
_yourTableView.backgroundColor = [UIColor clearColor];
I have a UITableView which when edited looks as follows :
Is it possible to somehow change the background behind the delete symbol so that it is not white ?
I hope this help you
UIView *cellBackView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
cellBackView.backgroundColor = [UIColor clearColor];
cell.cellBackgroundView = backView;
The problem ist that contentView gets shifted to the right when you are in editing mode, and because of this all its subviews will move to the right as well.
If your background is an imageView you should not add is as subview to contentView, set it as backgroundView of the cell instead.
Since you can't setup backgroundView from interface builder I would recommend to create a custom subclass of your cell and put the background creation into awakeFromNib.
- (void)awakeFromNib {
[super awakeFromNib];
self.backgroundView = [[UIImageView alloc] initWithImage:...];
}
My UITableViewCells are all pre-defined "Subtitle" style. I want to set the background image for a selected cell to another picture. I tried every which way to implement this and all methods discussed on stackoverflow seem to fail.
I tried again for some other, easier way to change the selectedBackgroundView property, like:
cell.selectedBackgroundView = [[UIView alloc] initWithFrame:cell.bounds] ;
cell.selectedBackgroundView.backgroundColor = [UIColor yellowColor];
But it doesn't work as well. What's wrong with that ?
As I understand you want to set selected background image to your cell?
cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"backgroundImage.png"]];
EDIT:
As i know UITableViewCell can not be highlighted after selection in such common cases:
There is somewhere set cell.selectionStyle = UITableViewCellSelectionStyleNone;
You implemented willSelectRowAtIndexPath and it returns nil;
There is set [self.tableView setAllowsSelection:NO];
May be you set self.tableView.userInteractionEnabled = NO; or cell.userInteractionEnabled = NO;
You subclassed UITableViewCell and implemented such methods not correct setSelected:animated: or setHighlighted:animated
May be share your cellForRowAtIndexPath method code to investigate the problem
You can change the highlight color in several ways.
Change the selectionStyle property of your cell. If you change it to UITableViewCellSelectionStyleGray, it will be gray.
you can also check that property in your tableView:didSelectRowAtIndexPath:
//do something like this for color
cell.selectionStyle= UITableViewCellSelectionStyleGray;
// for image
cell.selectedBackgroundView=[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"imageName"]];
Change the selectedBackgroundView property. Actually what creates the blue gradient is a view. You can create a view and draw what ever you like, and use the view as the background of your table view cells.
best of luck..
In my case the problem appeared after compiling on Xcode 13 - sdk iOS 15+
with any change to the code. Eventually I subclassed the cell and add the code:
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
[self.contentView insertSubview:self.selectedBackgroundView
atIndex:0];
self.selectedBackgroundView.hidden = !selected;
}
i try to set the UITableView Footerview backgroundcolor to clearColor but it stays white, any
other color works fine, any ideas?
_footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, _incredientsTable.frame.size.width, 60)];
[_footerView setBackgroundColor:[UIColor clearColor]];
Thanks.
Ask yourself these questions:
What do you expect to see through the footer view? Is it the table's background? The underlying view controller's views? In the latter case there are more views between your and the object that you want to be visible under the footer view. That is at least the UITable itself and probably the background of self.view (which in most cases but not all is the table)
You need to set background color of table view in this case.
tblView.backgroundColor = [UIColor clearColor];
I have managed to change the navigation bar to a custom stretch image and turn the back button a different colour. I'm having trouble setting a level number and coin total in the navigation bar.
I figure there has to be any easier way then messing about with progress HUD's and such - which is all I have seen mention from my research.
I'm trying to achieve a similar look to that attached below - element wise not graphically.
Thank you for any help in advance.
Two solutions:
Make the entire navigation bar into a custom view with your own elements, then update them as needed. Do this using the titleView property of UINavigationItem.
Use the leftBarButtonItem, titleView, and rightBarButtonItem with your own custom views.
I prefer the second method because it is more scalable (visually) - that is your view controller will layout correctly in landscape mode, or on an iPad, or in an oddly sized popover, etc. The left item will align to the left, the right to the right and the middle one in the middle. However, it's a bit more complicated because the left and right items need to be of type UIBarButtonItem. We can get around that like this:
// Set up the red star thing in the middle with a number 6 on it
MyRedStarView* redStarView = [MyRedStarView redStarViewWithValue:6];
self.navigationItem.titleView = redStarView;
// Set up the 'word' button on the left
MyWordButton* wordButton = [MyWordButton defaultWordButton];
UIView* buttonHolderView = [[UIView alloc] initWithFrame:CGRectZero];
buttonHolderView.backgroundColor = [UIColor clearColor];
[buttonHolderView addSubview:wordButton];
buttonHolderView.frame = wordButton.frame;
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonHolderView];
// Set up the coin indicator on the right
MyCoinView* coinView = [MyCoinView coinViewWithValue:515];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:coinView];
Notice how I wrapped the button (on the leftBarButtonItem) in a holder view - this is only necessary if you want to do some kind of view transitions on the button. For example if it changes in different contexts and you want to animate the transition by removing the button from the holder view and adding a different one (with a view transition). On the right bar button item I didn't do this, just to show the different approaches.
Of course I used some fake view types to demonstrate - you'd actually have your own references to these so that you can set the property values and update the display of the numbers.
try the following code assuming you already have the navigationView in place
- (void)viewDidLoad
{
// Custom Navigation Bar
// -----------------------------------
UIView *navigationCustomTitle = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 200.0, 20.0)];
navigationCustomTitle.backgroundColor = [UIColor clearColor];
UIImageView *icon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"icon.png"]];
UILabel *titleCustomLabel = [[UILabel alloc] initWithFrame:CGRectMake(30.0, 0.0, 260.0, 20.0)];
titleCustomLabel.text = #"A nice title";
titleCustomLabel.textColor = [UIColor whiteColor];
titleCustomLabel.backgroundColor = [UIColor clearColor];
titleCustomLabel.font = [UIFont fontWithName:#"HelveticaNeue-CondensedBold" size:(16.0)];
[navigationCustomTitle addSubview:titleCustomLabel];
[navigationCustomTitle addSubview:icon];
self.navigationItem.titleView = navigationCustomTitle;
}
