iOS 7 TableView like in Settings App on iPad
I've gone ahead and further customized the willDisplayCell to get a better simulation of the cell styles in the settings app.
Objective-C
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([cell respondsToSelector:@selector(tintColor)]) {
if (tableView == self.tableView) {
CGFloat cornerRadius = 5.f;
cell.backgroundColor = UIColor.clearColor;
CAShapeLayer *layer = [[CAShapeLayer alloc] init];
CGMutablePathRef pathRef = CGPathCreateMutable();
CGRect bounds = CGRectInset(cell.bounds, 10, 0);
BOOL addLine = NO;
if (indexPath.row == 0 && indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
CGPathAddRoundedRect(pathRef, nil, bounds, cornerRadius, cornerRadius);
} else if (indexPath.row == 0) {
CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds));
CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds), CGRectGetMidX(bounds), CGRectGetMinY(bounds), cornerRadius);
CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds));
addLine = YES;
} else if (indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds));
CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds), CGRectGetMidX(bounds), CGRectGetMaxY(bounds), cornerRadius);
CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds));
} else {
CGPathAddRect(pathRef, nil, bounds);
addLine = YES;
}
layer.path = pathRef;
CFRelease(pathRef);
layer.fillColor = [UIColor colorWithWhite:1.f alpha:0.8f].CGColor;
if (addLine == YES) {
CALayer *lineLayer = [[CALayer alloc] init];
CGFloat lineHeight = (1.f / [UIScreen mainScreen].scale);
lineLayer.frame = CGRectMake(CGRectGetMinX(bounds)+10, bounds.size.height-lineHeight, bounds.size.width-10, lineHeight);
lineLayer.backgroundColor = tableView.separatorColor.CGColor;
[layer addSublayer:lineLayer];
}
UIView *testView = [[UIView alloc] initWithFrame:bounds];
[testView.layer insertSublayer:layer atIndex:0];
testView.backgroundColor = UIColor.clearColor;
cell.backgroundView = testView;
}
}
}
Swift

iOS 7 change UITableViewCell font color to blue like in Settings app
If you're using a storyboard or xib and you have a prototype cell, go in to it and select the label. Then you can set the color of the text.
If you want to do it programmatically, add the following to your tableView:cellForRowAtIndexPath: method:
cell.textLabel.textColor = [UIColor blueColor];
blueColor isn't exactly the same as the blue used by buttons in iOS 7, but you could manually pick a color that closely approximates it if you wanted instead.
EDIT:
This will give you the exact color you want:
UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
cell.textLabel.textColor = [button titleColorForState:UIControlStateNormal];
It's getting the color from a UIButton.
Separator style like iPad settings app
It looks like they've used a section header view with a gradient background. Implement this method:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
Create a gradient 1px wide and whatever height you need tall. Create a view using that gradient as a background (it should tile horizontally) and return your custom view in that method (assuming the section passed to the method is correct).
You'll need to implement tableView:heightForHeaderInSection: too for this to work correctly.
Weird UITableViewCell selection in iOS7
I would make the tableview thinner (decrease width from both sides), then implement your looks so that the line would end not before edge of table view, but stretch all the way to the side of tableview.
In other words - decrease table view width to match current line width and leave the line as bid as it is now (it would then be as wide as tableview). Your selection will now be less wide too.
Or, upon selection you can modify your table view cell so that you mimic some custom selection. That could be from changing cell color up to flipping it with animations.
