    <p>I developing an application in which i want to print the values on a line interval, for that i used NSArray with multiple objects and those object i passing into CGContextShowTextAtPoint() method. The code is.</p> <pre><code> CGContextMoveToPoint(ctx, 30.0, 200.0); CGContextAddLineToPoint(ctx, 30.0, 440.0); NSArray *hoursInDays = [[NSArray alloc] initWithObjects:@"0",@"1",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12", nil]; int intHoursInDays = 0; for(float y = 400.0; y &gt;= 200.0; y-=18, intHoursInDays++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, 28, y); CGContextAddLineToPoint(ctx, 32, y); CGContextSelectFont(ctx, "Helvetica", 12.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); NSString *arrayDataForYAxis = [hoursInDays objectAtIndex:intHoursInDays]; CGContextShowTextAtPoint(ctx, 10.0, y+20, [arrayDataForYAxis UTF8String], strlen((char *)arrayDataForYAxis)); CGContextStrokePath(ctx); } </code></pre> <p>The above code is executed but it given me output is {oo, 1o,2o,...........11}, i want the output is {0,1,2,3...........11,12}. The above code given me one extra character "o" after single digit.I think the problem i meet near the parameters type casting of 5th parameter inside the method of CGContextShowTextAtpoint CGContextShowTextAtpoint(). How i resolve the problem of type casting for printing the objects of NSSArray in CGContextShowTextAtpoint() method??????????????</p>

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.
