[Cocoa]_[初级]_[如何绘制带颜色的文本]

场景:

1. 自定义view或其他控件时, 往往需要根据背景色或图片绘制特定颜色的文本.

    NSMutableDictionary* stringAttributes = [NSMutableDictionary dictionaryWithCapacity:1];
    //[stringAttributes setObject:[NSFont messageFontOfSize:12.0] forKey:NSFontAttributeName];
    [stringAttributes setObject:[NSColor whiteColor] forKey:NSForegroundColorAttributeName];
    
    NSString* systemCapacity = [NSString stringWithFormat:@"System: %@",[FileUtil ZLGetFormatSizeFromBytes:system]];
    NSSize systemSize = [systemCapacity sizeWithAttributes:stringAttributes];
    theRect1.origin.x += (theRect1.size.width - systemSize.width)/2;
    [systemCapacity drawAtPoint:theRect1.origin withAttributes:stringAttributes];
