    <p>I've been working on a little project of mien recently and trying to use this TableView I found on GitHub: <a href="https://github.com/nicolasgomollon/NGDynamicGradientCell" rel="nofollow">https://github.com/nicolasgomollon/NGDynamicGradientCell</a></p> <p>Unfortunately I'm not able to make it work as you can see on this Git: <a href="https://github.com/aout/TestForCells" rel="nofollow">https://github.com/aout/TestForCells</a></p> <p>It seems something is terribly wrong with the way I use it and particularly with the images. Without images everything works fine but when I add them I can't create any cells.</p> <p>here's a bit of code:</p> <pre><code>- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier { self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; if (self) { // Initialization code [self setSelectionStyle:UITableViewCellSelectionStyleNone]; [self setBackgroundColor:[UIColor whiteColor]]; maskFill = [UIImage imageNamed:@"mask-fill.png"]; maskFill = [maskFill resizableImageWithCapInsets:UIEdgeInsetsMake(1.0f, 1.0f, 1.0f, 1.0f)]; bubbleImage = [UIImage imageNamed:@"bubble-min.png"]; bubbleMaskImage = [UIImage imageNamed:@"mask-bubble-min.png"]; bubbleEdgeInsetsSent = UIEdgeInsetsMake(17.0f, 20.0f, 17.0f, 26.0f); bubbleEdgeInsetsReceived = UIEdgeInsetsMake(17.0f, 26.0f, 17.0f, 20.0f); bubbleMaskImage = [bubbleMaskImage resizableImageWithCapInsets:bubbleEdgeInsetsSent]; grayView = [[UIImageView alloc] initWithFrame:CGRectZero]; [grayView setBackgroundColor:[UIColor clearColor]]; [grayView setTintColor:RGBA(229.0f, 229.0f, 234.0f, 1.0f)]; [grayView setAlpha:0.0f]; [self.contentView addSubview:grayView]; messageLabel = [[UILabel alloc] initWithFrame:CGRectZero]; [messageLabel setBackgroundColor:[UIColor clearColor]]; [messageLabel setFont:[UIFont preferredFontForTextStyle:UIFontTextStyleBody]]; [messageLabel setLineBreakMode:NSLineBreakByWordWrapping]; [messageLabel setNumberOfLines:0]; [self.contentView addSubview:messageLabel]; } return self; } + (CGFloat)heightForMessage:(NSString *)message { UIFont *messageFont = [UIFont preferredFontForTextStyle:UIFontTextStyleBody]; CGSize messageConstraints = CGSizeMake(190.0f, MAXFLOAT); CGSize messageSize = [message boundingRectWithSize:messageConstraints options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName : messageFont } context:nil].size; CGFloat messageHeight = MAX(35.0f, 10.0f + roundf(messageSize.height) + 5.0f); return messageHeight + kMessagePadding; } - (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)newSize { UIGraphicsBeginImageContextWithOptions(newSize, NO, image.scale); [image drawInRect:CGRectSetSize(CGRectZero, newSize)]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return newImage; } - (void)drawRect:(CGRect)rect { [super drawRect:rect]; [messageLabel setFont:[UIFont preferredFontForTextStyle:UIFontTextStyleBody]]; [messageLabel setTextColor:self.sent?[UIColor whiteColor]:[UIColor blackColor]]; CGSize messageConstraints = CGSizeMake(190.0f, MAXFLOAT); CGSize messageSize = [messageLabel.text boundingRectWithSize:messageConstraints options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName : messageLabel.font} context:nil].size; CGFloat originX = 18.0f + kBubbleEdgeInset; if (self.sent) originX = self.bounds.size.width - messageSize.width - originX; [messageLabel setFrame:CGRectMake(originX, 7.0f, messageSize.width, messageSize.height)]; CGFloat messageWidth = MAX(48.0f, 13.0f + roundf(messageSize.width) + 18.0f); CGFloat messageHeight = MAX(35.0f, 10.0f + roundf(messageSize.height) + 5.0f); if (self.sent) { UIImage *maskImage = [self imageWithImage:bubbleMaskImage scaledToSize:CGSizeMake(messageWidth, messageHeight)]; UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, 0.0f); // Draw the bubble mask image. [maskImage drawInRect:CGRectMake(self.bounds.size.width - messageWidth - kBubbleEdgeInset, 0.0f, messageWidth, messageHeight)]; // Draw the message label text (since it'll be masked out).

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
