How can one reproduce the same effect as Single Line Etched when using plain table and custom cells?
I think I need to add them as subview to each cell, excluding the last one. I want to know how to reproduce that without having to use images to that. Does anyone know?
Isn't the separator just a single pixel grey line, even for Single Line Etched?
In this case, create a UIView the width of the cell, but only one pixel high and then set it's background colour,then stick it at the bottom of the cell's content view.
UIView *lineView;
lineView = [[UIView alloc] initWithFrame:CGRectMake(0.0f,
cell.contentView.bounds.size.height-1.0f,
cell.contentView.bounds.size.width,
1.0f);
lineView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin;
lineView.backgroundColor = [UIColor grayColor];
[cell.contentView addSubview:lineView];

I'm very new to Objective C but I'm looking at the source code of an existing app so there's a lot here to sift through.
I'm trying to create something like this:
-------------- or --------------
...only with a solid horizontal line instead of the dashes.
I have the "or" text defined as this:
_orLabel = ^{
UILabel* label = [[UILabel alloc] init];
label.translatesAutoresizingMaskIntoConstraints = NO;
label.textColor = [UIColor blackColor];
label.font = [UIFont mainFontWithSize:[UIFont preferredFontForTextStyle:UIFontTextStyleSubheadline].pointSize];
label.adjustsFontSizeToFitWidth = YES;
label.textAlignment = NSTextAlignmentCenter;
label.text = NSLocalizedString(#"or", nil);
[view addSubview:label];
return label;
}();
That's working great to get "or" to show up but I have no idea how to get the horizontal lines on either side.
I would subclass UILabel and override drawTextInRect:. The easiest way is to call super so that the text gets drawn. Now you are still in a graphics context (CGContext) so you can use ordinary Quartz drawing commands to draw your horizontal lines.
The simplest approach is to make use of certain Unicode characters that will give you a solid line.
label.text = #"───────── or ─────────";
That text is using a series of "BOX DRAWINGS LIGHT HORIZONTAL" characters (U+2500).
I would use IB to add a view on each side of the label. Make the views have a height of 1 or 2 with a black background, and use autolayout to make them size appropriately for the label and screen situation:
Make view #1 anchored to the left edge of the screen and the right side of the label.
Make view #2 anchored to the right edge of the screen and the left side of the label.
Make the 2 views and the label have the same vertical center.
Would somebody please explain how to create a one or two pixel drop shadow ONLY on the the very last cell (in other words, I don't want a shadow around the entire tableview, just the bottom cell. An image of what I'm talking about:
Solved. Use the following code to produce a very nice, subtle shadow to the bottom of your UITableViewCell. Makes it look like it's raised slightly out of the page :)
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(3, 49, cell.frame.size.width-26, 3)];/// change size as you need.
separatorLineView.backgroundColor = shadowColor;// you can also put image here
UIBezierPath *roundedShadow = [UIBezierPath bezierPathWithRoundedRect:separatorLineView.bounds byRoundingCorners:UIRectCornerBottomLeft|UIRectCornerBottomRight cornerRadii:CGSizeMake(8.0f, 8.0f)];
CAShapeLayer *newSeparatorShape = [[CAShapeLayer alloc] init];
[newSeparatorShape setPath:roundedShadow.CGPath];
separatorLineView.layer.mask = newSeparatorShape;
[cell.contentView addSubview:separatorLineView];
Also, don't forget to put this at the top of your .m file #import <QuartzCore/QuartzCore.h>
You could, in tableView:cellForIndexPath: set the cell's background image to one that includes the rounded corners with the shadow.
I'm having some trouble drawing a custom gradient background in a UITableViewCell when the style is set to 'grouped' and the cell is first or the last one of the section. My approach is to simply create a CAGradientLayer and add it to the view like this:
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = rect;
gradient.colors = [NSArray arrayWithObjects:(id)[_backgroundColorLight CGColor], (id)[_backgroundColorDark CGColor], nil];
[self.backgroundView.layer insertSublayer:gradient atIndex:0];
self.backgroundView.layer.masksToBounds = YES;
Unfortunately this produces cells like this one:
Does anyone have a hint on how to make the background fit the boarders of the cell?
Thanks

If you draw a custom background, you also have to draw the borders yourself. There's quite some open source stuff out there.
Basically, you need to know [in the cell] if it's top/middle/bottom/single, and cut the stuff in drawRect. You won't come far with insertSublayer.
Check out the PageCellBackground class you find here:

I've not tried it but CAGradientLayer happens to be a subclass of CALayer, so perhaps setting its borderRadius may work. But it rounds all corners then, so you may compensate for that by making the layer bigger than the cell and have the cell view cut it off.
Look at Rounded UIView using CALayers - only some corners - How? for more examples
I just wanted to know how I could draw a line dividing the cell's accessory view from the rest of the cell.
You could simply add a thin UIView (or UIImageView if you wanted a fancier divider) like so.
UIView *divider = [[UIView alloc] initWithFrame:CGRectMake(290, 3, 1, 38)];
[divider setBackgroundColor:[UIColor blackColor]];
[cell.contentView addSubview:divider];
[divider release];
If you're using one of UITableView's default accessory views, your content view will be squashed to make room for the accessory, so you your x-coordinate may have to change to sit at the very edge of the content view.
Is there any way to use autoresizing masks to move my content so that the delete button doesn't cover it up? Googling has told me that I need to set an autoresizing mask of UIViewAutoresizingFlexibleRightMargin on my subview. It seems to me like UIViewAutoresizingFlexibleWidth would actually make more sense; though I've tried them both and neither works.
The view that I am trying to shrink is just a label that is a subview of the cell's contentView. I am unsure if the contentView itself automatically resizes when the delete button shows up; but it seems like it isn't; otherwise my autoresizing mask should have worked.
If the presence of the delete button doesn't cause any views to be resized; is there anyway that I can do this manually?
You should use UIViewAutoresizingFlexibleLeftMargin.
Here's why. You want your contents to move to the left, basically making it seem like the delete button is pushing the contents to the left, out of it's way. flexibleLeftMargin basically means your UILabel will stay fixed to the right side of your contentView. The reason you want this, is because the delete button actually causes your contentView to shrink it's width.
The autoresizingmask of your UILabel refers to how it behaves inside the contentView, not the cell.
Give it a try, it should work.
This question is really old but I feel I should answer this anyway since I just found the solution myself.
Only the cell's ContentView gets resized with the confirmation button is shown. If you don't add your views (labels, imageviews, etc...) to the cell.contentView instead of adding them to the cell directly then they won't be resized when the contentView is resized. In my case, I was adding it to the cell directly.
So, instead of doing something like:
UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, width-10, 20)];
[nameLabel setFont:[UIFont boldSystemFontOfSize:16]];
[nameLabel setHighlightedTextColor:[UIColor whiteColor]];
[nameLabel setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[nameLabel setTag:101];
[cell addSubview:nameLabel];
[nameLabel release];
you should do:
UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, width-10, 20)];
[nameLabel setFont:[UIFont boldSystemFontOfSize:16]];
[nameLabel setHighlightedTextColor:[UIColor whiteColor]];
[nameLabel setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[nameLabel setTag:101];
[[cell contentView] addSubview:nameLabel]; // <<--- note the change in this line!
[nameLabel release];
Hope this helps others who stumble upon this issue.
I am using iOS 7, I got the same issue. I am using a separate xib for the UITableViewCell with auto layout enabled, so just added one more constraint to the label so that it will have a fixed gap on its right side.
