Replace the truncation ellipsis of UILabel in iOS 7 - ios

Question

How can I replace the truncation ellipsis ("…") of a UILabel in iOS 7 with another attributed character? For example, with a colored ">".
I was hoping Text Kit's NSLayoutManager would make this possible, but it appears UILabel doesn't make it public if it uses it.
Also, can I safely assume that an ellipsis is used as the truncation character in every localisation? Maybe different languages have different truncation characters.

Answer 1

I recommend you use TTTAttributedLabel, just set property "attributedTruncationToken" to your custom string.

Answer 2

I don't think it gives you access to this. I think you would have do handle it manually. For example, use TextKit to determine the size of your string, if it doesn't fit in the available area, truncate it yourself and append a ">" and then put your new string in the label.
NSAttributedString has methods for getting the size of the string.
Let me know if you need any more detail on this..?

Answer 3

I think you can do some customization in -replaceElipsesForLabel method provided by Fonix to get your desired result.

Answer 4

I have written a method to do it, and works in iOS7
-(void)setCustomEllipsis:(NSString*)customEllipsis inLabel:(UILabel*)label with:(NSString*)string{
//Replace the ellipsis
NSMutableString* result = [[NSMutableString alloc] initWithString:#""];
NSArray* strings = [string componentsSeparatedByString:#" "];
for (NSString* s in strings) {
CGRect newSize = [[NSString stringWithFormat:#"%#%#%#",result,s,customEllipsis] boundingRectWithSize:CGSizeMake(label.frame.size.width,0) options:NSStringDrawingUsesLineFragmentOrigin attributes:#{NSFontAttributeName:label.font} context:nil];
if (newSize.size.height < label.frame.size.height) {
[result appendString:s];
[result appendString:#" "];
}else{
[result appendString:customEllipsis];
break;
}
}
[label setText:result];
//Set different font to the ellipsis
const CGFloat fontSize = 13;
UIFont *boldFont = [UIFont boldSystemFontOfSize:fontSize];
UIFont *regularFont = [UIFont systemFontOfSize:fontSize];
UIColor *foregroundColor = [UIColor lightGrayColor];
NSDictionary *attrs = [NSDictionary dictionaryWithObjectsAndKeys:regularFont, NSFontAttributeName,foregroundColor, NSForegroundColorAttributeName, nil];
NSDictionary *subAttrs = [NSDictionary dictionaryWithObjectsAndKeys:boldFont, NSFontAttributeName, nil];
const NSRange range = [label.text rangeOfString:customEllipsis];
NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:result
attributes:attrs];
[attributedText setAttributes:subAttrs range:range];
[label setAttributedText:attributedText];
}
