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)
