How to show Bold and Italic both to My NSString without ThirdParty Libary in Objective-c

Question

Here is my code which I attempt :

NSString *strFirst = [NSString stringWithFormat:@"The App feature is only available to users while at "];
NSString *strAreaName = kAreaName;
NSRange boldedRange = [strAreaName rangeOfString:strAreaName];

NSMutableAttributedString *newAttString = [[NSMutableAttributedString alloc] initWithString:strFirst];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:strAreaName];
UIFont *fontText = [UIFont boldSystemFontOfSize:17.0];

NSDictionary *dictBoldText = [NSDictionary dictionaryWithObjectsAndKeys:fontText, NSFontAttributeName, nil];
[attrString setAttributes:dictBoldText range:boldedRange];

[newAttString appendAttributedString:attrString];

[lblFirst setAttributedText:newAttString];  

Output :
The App feature is only available to users while at America

But I want America in Bold and Italic both.

Please guide me to add in my String.

Thanks,

May be you can try below code:

//----Creating font dictionary for bold-italic text

UIFontDescriptor *fontDescriptor = [UIFontDescriptor preferredFontDescriptorWithTextStyle:UIFontTextStyleBody];

UIFontDescriptor *fontDescriptorNew;
NSDictionary *dictBoldItalicText;

uint32_t NewStyles = [fontDescriptor symbolicTraits] | UIFontDescriptorTraitBold | UIFontDescriptorTraitItalic;
fontDescriptorNew = [fontDescriptor fontDescriptorWithSymbolicTraits:NewStyles];
UIFont *updatedFont = [UIFont fontWithDescriptor:fontDescriptorNew size:17.0];//set your font size
dictBoldItalicText = @{ NSFontAttributeName : updatedFont };

//----------

NSString *strFirst = [NSString stringWithFormat:@"The App feature is only available to users while at "];
NSString *strAreaName=@"America";

NSRange boldedRange = [strAreaName rangeOfString:strAreaName];

NSMutableAttributedString *newAttString = [[NSMutableAttributedString alloc] initWithString:strFirst];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:strAreaName];


[attrString setAttributes:dictBoldItalicText range:boldedRange];//Assigning bold-italic attribute dictionary

[newAttString appendAttributedString:attrString];

[lblFirst setAttributedText:newAttString];

Tested and working fine.
