objective-c - NSImage 显示不正确（大小）

Question

我有一个带有自定义视图的 NSWindow。当我执行以下代码时，图像无法正确显示。它太小了。图像尺寸为 380x122。我究竟做错了什么？

NSImage *imageFromBundle = [NSImage imageNamed:@"about.bmp"];
NSImageView *imageView = [[NSImageView alloc] initWithFrame:NSMakeRect(0,0,380,122)];
[imageView setImage: imageFromBundle];
[_aboutCustomView addSubview:imageView];
[_aboutWindow center];
[_aboutWindow makeKeyAndOrderFront: nil];
[_aboutWindow display];
