TimOliver / UIScrollView+ZoomToPoint.m
Created August 2, 2013 07:25
A small category for UIScrollView to programatically zoom to a CGPoint as opposed to a CGRect. Currently in use in my iOS app, iComics (http://icomics.co)
@implementation UIScrollView (ZoomToPoint)
- (void)zoomToPoint:(CGPoint)zoomPoint withScale: (CGFloat)scale animated: (BOOL)animated
{
//Normalize current content size back to content scale of 1.0f
CGSize contentSize;
contentSize.width = (self.contentSize.width / self.zoomScale);
contentSize.height = (self.contentSize.height / self.zoomScale);
//translate the zoom point to relative to the content rect

A C function demonstrating how to draw the iOS 5-6 beveled effect that was prevalent in grouped UITableView implementations.
void DrawInsetBeveledRoundedRect( CGContextRef context, CGRect rect, CGFloat radius, UIColor *fillColor )
{
//contract the bounds of the rectangle in to account for the stroke
CGRect drawRect = CGRectInset(rect, 1.0f, 1.0f);
//contract the height by 1 to account for the white bevel at the bottom
drawRect.size.height -= 1.0f;
//Save the current state so we don't persist anything beyond this operation
CGContextSaveGState(context);

This is the method used to sort the filenames of pages inside an archive for iComics v1.1.
- (NSComparisonResult)sortedArchiveEntryIndex:(NSString *)firstName againstIndex:(NSString *)secondName
{
//if first name is empty, assume ascending
if ([firstName length] == 0)
return NSOrderedAscending;
if ([secondName length] == 0)
return NSOrderedDescending;
//convert the names to raw bytes so they can be manually compared on a numerical basis
