    <p>EDIT: Two years later, this post still get some karma and comments. Fixed my old answer to a better one.</p> <p>The most sensible, and reusable way to add a function which can take input between 0 and 255 for UIColor, is to create a custom category. Easier to read, easier to debug, easier for other people to contribute to, and keeps the project clean and structured as it grows beyond just a view viewcontrollers. So, add the following files, and import them in your m-files whereever you need them</p> <p>UIColor+Extra.h</p> <pre><code>@interface UIColor (Extra) + (UIColor *)colorWithR:(uint)red G:(uint)green B:(uint)blue A:(uint) alpha + (UIColor *) randomColor; + (UIColor *) colorWithHex:(uint) hex; @end </code></pre> <p>UIColor+Extra.m</p> <pre><code>#import "UIColor+Extra.h" @implementation UIColor (Extra) + (UIColor *)colorWithR:(uint)red G:(uint)green B:(uint)blue A:(uint) alpha { return [UIColor colorWithRed:red/255.0f green:green/255.0f blue:blue/255.0f alpha:alpha/100.f]; } + (UIColor *) randomColor { CGFloat red = (CGFloat)random()/(CGFloat)RAND_MAX; CGFloat blue = (CGFloat)random()/(CGFloat)RAND_MAX; CGFloat green = (CGFloat)random()/(CGFloat)RAND_MAX; return [UIColor colorWithRed:red green:green blue:blue alpha:1.0]; } + (UIColor *) colorWithHex:(uint) hex { int red, green, blue, alpha; blue = hex &amp; 0x000000FF; green = ((hex &amp; 0x0000FF00) &gt;&gt; 8); red = ((hex &amp; 0x00FF0000) &gt;&gt; 16); alpha = ((hex &amp; 0xFF000000) &gt;&gt; 24); return [UIColor colorWithRed:red/255.0f green:green/255.0f blue:blue/255.0f alpha:alpha/255.f]; } @end </code></pre>

    1. COThanks for the macros and advising where to place them :). These macros will make the code much easier to read, and take RGB colours created in other programs.

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.
