macos - 如何将NSString写入NSView？

Question

我可以使用类似的东西(UI 而不是 NS)写入 iOS。但在 OSX 上失败了？

NSString *sText = @"Hello";
[sText drawInRect:CGRectMake(x, y, 150, 20) withFont:[NSFont boldSystemFontOfSize:fSize]]; 
// No visible @interface for 'NSString' declares the selector 'drawInRect:withFont:'

您需要在 OS X 上使用 NSAttributedString 属性:

NSString *sText = @"Hello";
[sText drawInRect:CGRectMake(x, y, 150, 20) withAttributes: @{ NSFontAttributeName : 
                                             [NSFont boldSystemFontOfSize:fSize] }];
