    <p>I Write the Below Code for Drawing text by Using Bezier Paths.<br> Now here my task is How We Recognize the text which is Drawn by using Beizer Paths.<br> for example if I Draw "Apple" then my Label will show "U Have Drawn Apple".</p> <pre><code>@implementation NaiveVarWidthView { UIBezierPath *path; UIImage *incrementalImage; CGPoint pts[5]; uint ctr; } - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { [self setMultipleTouchEnabled:NO]; path = [UIBezierPath bezierPath]; } return self; } - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { ctr = 0; UITouch *touch = [touches anyObject]; pts[0] = [touch locationInView:self]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint p = [touch locationInView:self]; ctr++; pts[ctr] = p; if (ctr == 4) { pts[3] = CGPointMake((pts[2].x + pts[4].x)/2.0, (pts[2].y + pts[4].y)/2.0); [path moveToPoint:pts[0]]; [path addCurveToPoint:pts[3] controlPoint1:pts[1] controlPoint2:pts[2]]; UIGraphicsBeginImageContextWithOptions(self.bounds.size, YES, 0.0); // if (!incrementalImage) { UIBezierPath *rectpath = [UIBezierPath bezierPathWithRect:self.bounds]; [[UIColor whiteColor] setFill]; [rectpath fill]; } [incrementalImage drawAtPoint:CGPointZero]; [[UIColor blackColor] setStroke]; float speed = 0.0; for (int i = 0; i &lt; 3; i++) { float dx = pts[i+1].x - pts[i].x; float dy = pts[i+1].y - pts[i].y; speed += sqrtf(dx * dx + dy * dy); } #define FUDGE_FACTOR 100 float width = FUDGE_FACTOR/speed; [path setLineWidth:width]; [path stroke]; incrementalImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [self setNeedsDisplay]; [path removeAllPoints]; pts[0] = pts[3]; pts[1] = pts[4]; ctr = 1; } } - (void)drawRect:(CGRect)rect { [incrementalImage drawInRect:rect]; } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [self setNeedsDisplay]; } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesEnded:touches withEvent:event]; } @end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
