    <p><strong>Edit (I re-read the question and you might want what the other answer from Stew suggested):</strong></p> <pre><code>BOOL myBool = [@"1" boolValue]; myBool = [someObject boolValue]; </code></pre> <p>These are some of the conversion methods for NSString - Also see the <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html" rel="nofollow">NSString Reference Here</a>:</p> <pre><code>- (double)doubleValue; - (float)floatValue; - (int)intValue; - (NSInteger)integerValue; - (long long)longLongValue; // (boolValue) Skips initial space characters (whitespaceSet), // or optional -/+ sign followed by zeroes. // Returns YES on encountering one of "Y", "y", "T", "t", or a digit 1-9. // It ignores any trailing characters. - (BOOL)boolValue; </code></pre> <p><br/></p> <p>Also, from <a href="http://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/nsnumber_Class/Reference/Reference.html#//apple_ref/occ/instm/NSNumber/boolValue" rel="nofollow">NSNumber Class Reference</a>:</p> <blockquote> <p>boolValue Returns the receiver’s value as a BOOL.</p> <p><code>- (BOOL)boolValue</code></p> <p>Return Value The receiver’s value as a BOOL, converting it as necessary.</p> <p>Special Considerations Prior to Mac OS X v10.3, the value returned isn’t guaranteed to be one of YES or NO. A 0 value always means NO or false, but any nonzero value should be interpreted as YES or true.</p> </blockquote> <hr> <p><strike> Try this:</p> <pre><code>[NSNumber numberWithBool:YES] [NSNumber numberWithBool:NO] [NSNumber numberWithInt:1] [NSNumber numberWithFloat:0.25] // etc... - (IBAction)Calcluate:(id)sender { BOOL something; something = [hi [NSNumber numberWithBool:BOOL]]; } </code></pre> <p><a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/nsnumber_Class/Reference/Reference.html" rel="nofollow">NSNumber reference</a></p> <p>Since things like <code>BOOL</code>, <code>NSInteger</code>, <code>NSUInteger</code>, etc are not pointers, they cannot do certain things like be values for a dictionary, etc. For this purpose, NSNumber was created. It wraps these types in a class so they can be used as arguments for passing to <code>selectors</code>, or stored in <code>NSDictionary</code>'s.</p> <p>Here is a common thing I do:</p> <pre><code>[self.myLoadingView performSelectorOnMainThread:@selector(setHidden:) withObject:[NSNumber numberWithBool:YES] waitUntilDone:YES]; </code></pre> <p></strike></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.
