Wrong popup height when using attributed subtitle string

[tvlc]

Hi, there is a bug in calculation of popup height when using attributed string as a subtitle, see scrennshots.

Atributes used:

`

NSMutableParagraphStyle *attributedStringParagraphStyleTitle = [[NSParagraphStyle defaultParagraphStyle]mutableCopy];
attributedStringParagraphStyleTitle.alignment = NSTextAlignmentCenter;
attributedStringParagraphStyleTitle.paragraphSpacing = 6.0;

NSMutableParagraphStyle *attributedStringParagraphStyleSubtitle = [[NSParagraphStyle defaultParagraphStyle]mutableCopy];
attributedStringParagraphStyleSubtitle.alignment = NSTextAlignmentCenter;
attributedStringParagraphStyleSubtitle.paragraphSpacing = 12.0;

NSMutableParagraphStyle *attributedStringParagraphStyle = [[NSParagraphStyle defaultParagraphStyle]mutableCopy];
attributedStringParagraphStyle.alignment = NSTextAlignmentCenter;
attributedStringParagraphStyleSubtitle.paragraphSpacing = 3.0;

NSString *strKey  = annotation.featurePoint.featureKey;
NSDictionary *attrKey = @{ NSForegroundColorAttributeName:ansColorBlueLagoon,
                           NSParagraphStyleAttributeName:attributedStringParagraphStyleTitle,
                           NSFontAttributeName:[UIFont fontWithName:@"Futura-Bold" size:18.0] };    // [UIFont boldSystemFontOfSize:18.0f]

NSString *strName = annotation.featurePoint.featureName;
NSDictionary *attrName = @{ NSForegroundColorAttributeName:ansColorSapphire,
                            NSParagraphStyleAttributeName:attributedStringParagraphStyleSubtitle,
                            NSFontAttributeName:[UIFont fontWithName:@"Futura-Bold" size:16.0] };    // [UIFont boldSystemFontOfSize:18.0f]

NSString *strFir  = annotation.featurePoint.featureFIR";
NSDictionary *attrFir  = @{ NSForegroundColorAttributeName:ansColorSapphire,
                            NSParagraphStyleAttributeName:attributedStringParagraphStyle,
                            NSFontAttributeName:[UIFont fontWithName:@"Futura-Bold" size:16.0] };    // [UIFont boldSystemFontOfSize:18.0f]

NSString *strCoordinate = annotation.featurePoint.featureCoordinate;
NSDictionary *attrCoordinate = @{ NSForegroundColorAttributeName:ansColorCelurean,
                                  NSParagraphStyleAttributeName:attributedStringParagraphStyle,
                                  NSFontAttributeName:[UIFont fontWithName:@"Futura-Bold" size:14.0] };    // [UIFont boldSystemFontOfSize:18.0f]

NSAttributedString *attribText = [NSAttributedString rz_attributedStringWithStringsAndAttributes:
                                  [NSString stringWithFormat:@"%@\n",strKey],attrKey,
                                  [NSString stringWithFormat:@"%@\n",strName],attrName,
                                  [NSString stringWithFormat:@"FIR: %@\n",strFir],attrFir,
                                  [NSString stringWithFormat:@"Lat/Lon: %@",strCoordinate],attrCoordinate,
                                  nil];

Hey @tvlc, Thanks for using FCAlertView. Will look into this. @digitalcatnip Would you mind taking a look at what might be causing this. Thanks!

[digitalcatnip]

Sorry, just saw this - I will take a look when I have a chance!

[tvlc]

Any progress? See three dots added at the end of the string, when the string has been truncated and missing last line of the attributed text

[tvlc]

@digitalcatnip Have you already a chance to look at it?

I found a bug in implementation of drawRect method - it does not properly calculate the bounding box size for attributed subtitle.
Proposal for solution:

    CGSize boundingBox;
    if (descriptionLabel.attributedText == nil) {
        boundingBox = [descriptionLabel.text boundingRectWithSize:constraint
                                                             options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading
                                                          attributes:@{NSFontAttributeName:descriptionLabel.font}
                                                             context:context].size;
    } else {
        boundingBox = [descriptionLabel.attributedText boundingRectWithSize:constraint
                                                                           options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading
                                                                           context:context].size;
    }
