Any way to print in color with NSLog?


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

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:

A line like this works for me:

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

(More colors available here)

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


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.

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