NSAttributeString Wrapping issue

I am trying to set attribute text to a label. The attributes seems to be a working the font as well as the color.

Only issue I am facing is the wrapping of lines. The Size of the UILabel is (200,300) with numberofLines=0. So with this it should wrap the lines, but it is not happening so.

   NSMutableString *title=[[NSMutableString alloc] init];
    NSRange range1;
    NSRange range2;
    NSRange range3;



        NSString *str1=@"ABCD EFGHI klm";
        [title appendString:str1];
        range1=NSMakeRange(0, str1.length);


        NSString *str2=@"PQRSSSS ";
        [title appendString:str2];
        range2=NSMakeRange(range1.length, str2.length);


        NSString *str3=@"1235 2347 989034 023490234 90";
        [title appendString:str3];
        range3=NSMakeRange(range2.location+range2.length, str3.length);


    NSMutableAttributedString *attributeText=[[NSMutableAttributedString alloc] initWithString:title];
    [attributeText setAttributes:[NSDictionary dictionaryWithObjectsAndKeys:color1,NSForegroundColorAttributeName,[self getStlylishItalicFont:13.0] ,NSFontAttributeName,nil] range:range1];
    [attributeText setAttributes:[NSDictionary dictionaryWithObjectsAndKeys:color2,NSForegroundColorAttributeName,[self getStylishFont:13.0] ,NSFontAttributeName,nil] range:range2];
    [attributeText setAttributes:[NSDictionary dictionaryWithObjectsAndKeys:color3,NSForegroundColorAttributeName,[self getStylishBoldFont:13.0] ,NSFontAttributeName,nil] range:range3];

    self.myTextLabel.attributedText=attributeText;

UILabel is displayed like this, even though the height is 300.

ABCD EFGHI klm PQRSSSS 1235 234 ...

along with setting:

    self.myTextLabel.lineBreakMode = NSLineBreakByWordWrapping;
    self.myTextLabel.numberOfLines = 0;

You might also need to set your label's layout constraints to it's superview. I ran into this when I neglected to pin my label's trailing constraint to the my label's superview.

What you need is the NSParagraphStyle attribute :

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
paragraphStyle.alignment = NSTextAlignmentLeft;
paragraphStyle.lineSpacing = 1;

//Now add this to your attributes dictionary for the key NSParagraphStyleAttributeName eg,

@{NSParagraphStyleAttributeName:paragraphStyle,...}

On an unrelated note you know its better to create dictionaries in the modern Objective-c format. Whenever I don't, my mentor get's angry. That would look something like this :

[attributeText setAttributes:@{NSForegroundColorAttributeName:color1, NSFontAttributeName:[self getStlylishItalicFont:13.0], NSParagraphStyleAttributeName:paragraphStyle, }];
//The trailing comma in the dictionary definition is not at typo it is important.

Make sure you set your UILabel's line break mode attribute to the one you desired like so:

UILabel.lineBreakMode = NSLineBreakByWordWrapping;

Or if you are using Interface Builder, you can do it there.

I think so u are facing the problem with the uilabel increasing the height , If u need the multiple lines in label then u have to give the property of havin numberoflines=0; after that u have to resize the label frame according to the size of text u are giving to the label.

Please check the below code i may be useful to u,

        NSString *someText = [NSString stringWithFormat:@"%@",[[arrFulldetails objectAtIndex:indexPath.row]valueForKey:@"MessageText"]];
        CGSize constraintSize;
        constraintSize.width = 300.0f;
        constraintSize.height =100000;
        CGSize stringSize =[someText sizeWithFont: [UIFont boldSystemFontOfSize: 17] constrainedToSize: constraintSize lineBreakMode: UILineBreakModeWordWrap];
        CGRect rect ;
        rect = CGRectMake(10, 150, 210, 20+stringSize.height);

Why can't you set the numberoflines to 1.Because wrapping makes sense but number of lines 0 doesnt make sense.. and also you have to set proper frame for label.
