nsstring - How to use drawInRect:withAttributes: instead of drawAtPoint:forWidth:withFont:fontSize:lineBreakMode:baselineAdjustment: in iOS 7

Question

This method is deprecated in iOS 7.0:

drawAtPoint:forWidth:withFont:fontSize:lineBreakMode:baselineAdjustment:

Now use drawInRect:withAttributes: instead.

I can't find the attributeName of fontSize and baselineAdjustment.

Edit

Thanks @Puneet answer.

Actually, I mean if there doesn't have these key, how to implement this method in iOS 7?

Like below method:

+ (CGSize)drawWithString:(NSString *)string atPoint:(CGPoint)point forWidth:(CGFloat)width withFont:(UIFont *)font fontSize:(CGFloat)fontSize
           lineBreakMode:(IBLLineBreakMode)lineBreakMode
      baselineAdjustment:(UIBaselineAdjustment)baselineAdjustment {
    if (iOS7) {
        CGRect rect = CGRectMake(point.x, point.y, width, CGFLOAT_MAX);

        NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
        paragraphStyle.lineBreakMode = lineBreakMode;

        NSDictionary *attributes = @{NSFontAttributeName: font, NSParagraphStyleAttributeName: paragraphStyle};

        [string drawInRect:rect withAttributes:attributes];

        size = CGSizeZero;
    }
    else {
        size = [string drawAtPoint:point forWidth:width withFont:font fontSize:fontSize lineBreakMode:lineBreakMode baselineAdjustment:baselineAdjustment];
    }
    return size;
}

I don't know how to pass fontSize and baselineAdjustment to

attributes dictionary.

e.g.

NSBaselineOffsetAttributeName key should pass a NSNumer to it, but the baselineAdjustment is Enum.

Isn't there have other way to pass the two variables?

You can use NSDictionary and apply attributes like this:

NSFont *font = [NSFont fontWithName:@"Palatino-Roman" size:14.0];

NSDictionary *attrsDictionary =

[NSDictionary dictionaryWithObjectsAndKeys:
                              font, NSFontAttributeName,
                              [NSNumber numberWithFloat:1.0], NSBaselineOffsetAttributeName, nil];

Use attrsDictionary as argument.

Refer: Attributed String Programming Guide

Refer: Standard Attributes

SWIFT: IN String drawInRect is not available but we can use NSString instead:

let font = UIFont(name: "Palatino-Roman", size: 14.0)
let baselineAdjust = 1.0
let attrsDictionary =  [NSFontAttributeName:font, NSBaselineOffsetAttributeName:baselineAdjust] as [NSObject : AnyObject]
let str:NSString = "Hello World"
str.drawInRect(CGRectZero, withAttributes: attrsDictionary)
