    <p>Since this might be useful for other coming across this issue here is a little table showing you the actual effect of casting. These values were taken straight from the debugger as hex values. Choose accordingly, as you can see casting does cause effects. For 32-bit, lop off the bottom <strong>ffffffff</strong> and for 16-bit lop off bottom <strong>ffffffffffff</strong>. Also note, -1 is always 0xffffffffffffffff. </p> <pre><code>NSInteger si = NSIntegerMax; // si NSInteger 0x7fffffffffffffff si = -1; // si NSInteger 0xffffffffffffffff si = (NSInteger)-1; // si NSInteger 0xffffffffffffffff si = (NSUInteger)-1; // si NSInteger 0xffffffffffffffff si = NSUIntegerMax; // si NSInteger 0xffffffffffffffff si = (NSInteger)NSIntegerMax; // si NSInteger 0x7fffffffffffffff si = (NSUInteger)NSIntegerMax; // si NSInteger 0x7fffffffffffffff si = (NSInteger)NSUIntegerMax; // si NSInteger 0xffffffffffffffff si = (NSUInteger)NSUIntegerMax; // si NSInteger 0xffffffffffffffff NSUInteger ui = NSUIntegerMax; // ui NSUInteger 0xffffffffffffffff ui = -1; // ui NSUInteger 0xffffffffffffffff ui = (NSInteger)-1; // ui NSUInteger 0xffffffffffffffff ui = (NSUInteger)-1; // ui NSUInteger 0xffffffffffffffff ui = NSIntegerMax; // ui NSUInteger 0x7fffffffffffffff ui = (NSInteger)NSIntegerMax; // ui NSUInteger 0x7fffffffffffffff ui = (NSUInteger)NSIntegerMax; // ui NSUInteger 0x7fffffffffffffff ui = (NSInteger)NSUIntegerMax; // ui NSUInteger 0xffffffffffffffff ui = (NSUInteger)NSUIntegerMax; // ui NSUInteger 0xffffffffffffffff </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.
