上一篇已经对于xib与控件之间的关系都大致介绍了；
那么本篇不再详细解释如何如何连接控件以及控件代码等，直接给出代码以及需要注意的简单介绍下，便于童鞋们使用时可以给与参考：
1. 首先创建一个MyView类，继承NSView，如下：

if (self) {
// Initialization code here.
}
return self;
}- (void)drawRect:(NSRect)dirtyRect
{ NSString * str =@"MyView --by Himi";
//属性包装设置
NSMutableDictionary *dic = [NSMutableDictionary dictionary];
//设置字体样式
[dic setObject:[NSFont fontWithName:@"Times" size:14] forKey:NSFontAttributeName];
//设置字体颜色
[dic setObject:[NSColor redColor] forKey:NSForegroundColorAttributeName];
//绘制
[str drawAtPoint:NSMakePoint(50, 50) withAttributes:dic];
}@end |
代码很easy理解，不在赘述啦～

运行截图如下：
