NSMutableAttributedString set font size
提问by steven
Every resource I keep coming across for this is for iOS. I can't seem to get this working properly for Mac OSX. Any idea how to get this to set the font size as well? It currently sets the color and center alignment properly. Thanks

NSMutableAttributedString *libTitle = [[NSMutableAttributedString alloc] initWithString:@"Library"];
[libTitle addAttribute:NSForegroundColorAttributeName value:[NSColor whiteColor] range:NSMakeRange(0,[@"Library" length] ) ];
[libTitle setAlignment:NSCenterTextAlignment range:NSMakeRange(0, [@"Library" length])];
[libTitle addAttribute:NSFontSizeAttribute value:[NSFont systemFontOfSize:18.0] range:NSMakeRange(0, [@"Library" length])];
[self.libbtn setAttributedTitle:libTitle];

Try setting your font attributes from the get go, in the init method:
尝试从一开始就在 init 方法中设置字体属性：
NSFont *systemFont = [NSFont systemFontOfSize:18.0f];
NSDictionary * fontAttributes = [[NSDictionary alloc] initWithObjectsAndKeys:systemFont, NSFontAttributeName, nil];
NSMutableAttributedString *libTitle = [[NSMutableAttributedString alloc] initWithString:@"Library" attributes:fontAttributes];
NSRange rangeOfTitle = NSMakeRange(0,[libTitle length]);
[libTitle addAttribute:NSForegroundColorAttributeName value:[NSColor whiteColor] range:rangeOfTitle];
[libTitle setAlignment:NSCenterTextAlignment range:rangeOfTitle];
[self.libbtn setAttributedTitle:libTitle];
