    <p>I don't think there is any silver bullet for this. </p> <p>Here is a category method that seems to work for the few basic test cases I threw at it. No guarantees it won't break with something complex!</p> <p>The way it works is to move through the string testing to see if a range of words fits in the width of the label. When it calculates that the current range is too wide it records the last-fitting range as a line.</p> <p>I don't claim this is efficient. A better way may just to be to implement your own UILabel...</p> <pre><code>@interface UILabel (Extensions) - (NSArray*) lines; @end @implementation UILabel (Extensions) - (NSArray*) lines { if ( self.lineBreakMode != UILineBreakModeWordWrap ) { return nil; } NSMutableArray* lines = [NSMutableArray arrayWithCapacity:10]; NSCharacterSet* wordSeparators = [NSCharacterSet whitespaceAndNewlineCharacterSet]; NSString* currentLine = self.text; int textLength = [self.text length]; NSRange rCurrentLine = NSMakeRange(0, textLength); NSRange rWhitespace = NSMakeRange(0,0); NSRange rRemainingText = NSMakeRange(0, textLength); BOOL done = NO; while ( !done ) { // determine the next whitespace word separator position rWhitespace.location = rWhitespace.location + rWhitespace.length; rWhitespace.length = textLength - rWhitespace.location; rWhitespace = [self.text rangeOfCharacterFromSet: wordSeparators options: NSCaseInsensitiveSearch range: rWhitespace]; if ( rWhitespace.location == NSNotFound ) { rWhitespace.location = textLength; done = YES; } NSRange rTest = NSMakeRange(rRemainingText.location, rWhitespace.location-rRemainingText.location); NSString* textTest = [self.text substringWithRange: rTest]; CGSize sizeTest = [textTest sizeWithFont: self.font forWidth: 1024.0 lineBreakMode: UILineBreakModeWordWrap]; if ( sizeTest.width &gt; self.bounds.size.width ) { [lines addObject: [currentLine stringByTrimmingCharactersInSet:wordSeparators]]; rRemainingText.location = rCurrentLine.location + rCurrentLine.length; rRemainingText.length = textLength-rRemainingText.location; continue; } rCurrentLine = rTest; currentLine = textTest; } [lines addObject: [currentLine stringByTrimmingCharactersInSet:wordSeparators]]; return lines; } @end </code></pre> <p>use like this:</p> <pre><code>NSArray* lines = [_theLabel lines]; int count = [lines count]; </code></pre>

    1. COThanks TomSwift for your input... This sort of works for some cases, but it definitely gave me a big boost, I'm working on a more bullet proof solution based on your code. Thanks again!

    3. CONice solution TomSwift. But it doesn't work for me, it's always the text on one line though int count sometimes are 9, 10 or 20. My code: self.labelDescription.text = event.description; self.labelDescription.lineBreakMode = UILineBreakModeWordWrap; self.labelDescription.font = [UIFont fontWithName:@"Helvetica" size:13.0]; NSArray* lines = [self.labelDescription lines]; int count = [lines count]; self.labelDescription.numberOfLines = count;

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.
