有什么办法用NSLog打印彩色？

In a typical color terminal, there are escape sequences that one can use to print text in different colors. Typically there are 8 colors available. I tried using the standard, ANSI escape sequences for this in NSLog, but no dice. It does not support by that mechanism.

在典型的彩色终端中，存在可用于以不同颜色打印文本的转义序列。通常有8种颜色可供选择。我尝试在NSLog中使用标准的ANSI转义序列，但没有骰子。它不支持该机制。

Is there a different way to print to the console (log) in color using NSLog?

是否有不同的方法使用NSLog以彩色打印到控制台（日志）？

Thanks.

谢谢。

You can use Apple Color Emoji to add some color to your Log output like this:

您可以使用Apple Color Emoji为日志输出添加一些颜色，如下所示：

if ([self isKindOfClass:[UITableViewController class]])
    NSLog(@"???? Table View controller Will appear: %@", NSStringFromClass([self class]));
else  if ([self isKindOfClass:[UINavigationController class]])
    NSLog(@"???? Navigation controller Will appear: %@", NSStringFromClass([self class]));
else
    NSLog(@"???? View controller Will appear: %@", NSStringFromClass([self class]));

Because the above code might by displayed incorrectly on non-OS-X-platforms, I attached a screenshot of XCode, showing the code and log output:

因为上面的代码可能在非OS-X平台上显示不正确，所以我附上了XCode的截图，显示了代码和日志输出：

A line like this works for me:

像这样的一条线对我有用：

NSLog(@"\e[1;31mRed text here\e[m normal text here");

(More colors available here)

（这里有更多颜色）

Note that you have to actually watch your output in regular console, as Xcode debugging console doesn't seem to support coloring.

请注意，您必须在常规控制台中实际观察输出，因为Xcode调试控制台似乎不支持着色。

Ayoy's approach seems to work in general in a command line based app with printf:

Ayoy的方法似乎在基于命令行的应用程序中使用printf：

However, I don't think this works with the built-in Xcode console:

但是，我不认为这适用于内置的Xcode控制台：

This:

这个：

NSLog(@"\e[1;31mRed text here\e[m normal text here");

... results in this:

You can colorize your NSLog output using this Xcode plugin: https://github.com/DeepIT/XcodeColors

I wrote a few lines with my quick setup instructions and simple custom macros.

我用快速设置说明和简单的自定义宏写了几行。

Update: I'm using now NSLogger with color support. Much powerful.

更新：我现在正在使用带有颜色支持的NSLogger。功能强大。
