On a fresh install getting: Unable to find symbol CALayer

Just now I wanted to add a border to a UIView where only the top, left, right are drawn (bottom is empty).

I made a custom class that overrides UIView.

Rather than make this small class, how about a CKDrawbleView where you can add it directly as a sub-view to your view like so:

[myView addSubView:[CKDrawableView alloc] initWithBlock:^(CGRect rect){

//do my drawing here;

}];

Avoids typing: view.frame.size.width . . which is too verbose.

I'm not sure if this is generally useful or not, but if you think so please add:

@implementation UITableView (IndexPaths)

• (NSIndexPath_)nextIndexPathGiven:(NSIndexPath_)indexPath
  {
  NSIndexPath* nextIndexPath = nil;
  if ([self canEvaluateNextOrPreviousIndexPathGiven:indexPath])
  {
  id delegate = self.dataSource;
  NSInteger sections = [delegate numberOfSectionsInTableView:self];
  NSInteger rowsInSection = [delegate tableView:self numberOfRowsInSection:indexPath.section];
  NSInteger nextRow = indexPath.row + 1;

  if (nextRow == rowsInSection && indexPath.section <= (sections - 1))
  {
      nextIndexPath = [NSIndexPath indexPathForRow:0 inSection:indexPath.section + 1];
  }
  else
  {
      nextIndexPath = [NSIndexPath indexPathForRow:indexPath.row + 1 inSection:indexPath.section];

  return nextIndexPath;

Add a CKUITools.h header file that imports everything. . . then I don't have to remember the category names.

I want to use this in a CocoaPods project. . . would be nice if it was in the official specs repo, although I guess I could resolve it as an in-line spec. . .

Steps to reproduce.

1. Create an empty project.
2. Add a View Controller
3. Add a view with only a UITextView. . . confirm that the text view is happy.
4. Add CKUITools via CocoaPods

UITextView has blank text!!!!!

1. Add a different library via CocoaPods

UITextView is ok.

Wierd. . .

Add the following method:

This is the content frame, which is either the whole screen, or the whole screen minus the status bar.

• (CGRect)contentFrame
  {
  CGSize currentSize = [self currentSize];
  if ([UIApplication sharedApplication].statusBarHidden)
  {
  return CGRectMake(0, 0, currentSize.width, currentSize.height);
  }
  else
  {
  CGFloat statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;
  return CGRectMake(0, statusBarHeight, currentSize.width, currentSize.height - statusBarHeight);
  }
  }
