Unfortunately you need to be smarter than what is provided by Apple : <pre><code>stringByAddingPercentEscapesUsingEncoding: </code></pre> This will escape all invalid URL characters so that "http://foo.com/hey%20dude/", which is valid, becomes "http://foo.com/hey%2520dud/", which is not what we want. According to apple documentation : <a href="http://developer.apple.com/library/mac/documentation/CoreFOundation/Reference/CFURLRef/Reference/reference.html#//apple_ref/c/func/CFURLCreateStringByAddingPercentEscapes" rel="nofollow">http://developer.apple.com/library/mac/documentation/CoreFOundation/Reference/CFURLRef/Reference/reference.html#//apple_ref/c/func/CFURLCreateStringByAddingPercentEscapes</a> I made an NSURL category which does the right thing and works with odd string such as ones with partial encoding (i.e. "http://foo.com/hey dude/i%20do%20it/"). Here is the code: <pre><code>@interface NSURL (SmartEncoding) + (NSURL *)smartURLWithString:(NSString *)str; @end @implementation NSURL (SmartEncoding) + (NSURL *)smartURLWithString:(NSString *)str { CFStringRef preprocessed = CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (CFStringRef)str, CFSTR(""), kCFStringEncodingUTF8); if (!preprocessed) preprocessed = CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (CFStringRef)str, CFSTR(""), kCFStringEncodingASCII); if (!preprocessed) return [NSURL URLWithString:str]; CFStringRef sanitized = CFURLCreateStringByAddingPercentEscapes(NULL, preprocessed, NULL, NULL, kCFStringEncodingUTF8); CFRelease(preprocessed); NSURL *result = (NSURL*)CFURLCreateWithString(NULL, sanitized, NULL); CFRelease(sanitized); return [result autorelease]; } @end </code></pre> It works fine with UTF8 string encoded and ASCII ones.

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.
