如何让这段代码更优雅？

Question

-(NSMutableAttributedString *) masBlueBoldColorString:(NSString *) theString 
{ 



    UIFont * italicSystemFont = [UIFont fontWithName:@"HelveticaNeue-Bold" size:sizeOfFonthighLightSomeStuff]; 


    CTFontRef font = CTFontCreateWithName((__bridge CFStringRef)italicSystemFont.fontName, italicSystemFont.pointSize, NULL); 
    NSRange rangeHighlight = NSMakeRange(0, theString.length); 

    NSMutableAttributedString * mutableAttributedString = [[ NSMutableAttributedString alloc]initWithString:theString]; 

    if (font) { 
     [mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)font range:rangeHighlight]; 
     CFRelease(font); 
    } 

    return mutableAttributedString; 
} 

有一些问题，此代码....

我想要的“字体”通过一个方法返回。我们有CFAutoRelease吗？如果我们根本不需要使用字体，它会更好

Answer 1

- (UIFont*)myFontMethod 
{ 
    return [UIFont fontWithName:@"HelveticaNeue-Bold" size:sizeOfFonthighLightSomeStuff]; 
} 

-(NSMutableAttributedString *) masBlueBoldColorString:(NSString *) theString 
{ 
    UIFont * font = [self myFontMethod]; 

    NSMutableAttributedString * mutableAttributedString = [[NSMutableAttributedString alloc] initWithString:theString]; 

    if (font) { 
     [mutableAttributedString addAttribute:NSFontNameAttribute value:font]; 
    } 

    return mutableAttributedString; 
}
