How to print Boolean flag in NSLog?

🕹️ How to Print Boolean Flag in NSLog? 🖨️

So you're building your awesome iOS app and you have a Boolean flag that you want to print using NSLog. You want to see if the flag is true or false in your console output. Well, the good news is, you've come to the right place! In this guide, we'll explore some common issues around printing Boolean flags in NSLog and provide you with easy solutions.

The Problem 😕

Let's set the context first. Imagine you have a Boolean flag called isFlagSet in your iOS app. You want to check its value during runtime and see its state through NSLog. But when you try to print it using NSLog, you end up with some unexpected results. It's frustrating, right?

The Solution 💡

The issue arises because NSLog is designed to print objects, not primitive data types like Boolean. But worry not, we have a few simple solutions for you:

Solution 1: Converting Boolean to NSString

One way to overcome this issue is by converting your Boolean flag to an NSString using the NSString's stringWithFormat: method. You can simply convert your Boolean flag into a string and then pass it to NSLog like this:

BOOL isFlagSet = YES; // Set your Boolean flag here
NSString *flagString = isFlagSet ? @"YES" : @"NO";
NSLog(@"isFlagSet: %@", flagString);

🚀 Example output: isFlagSet: YES (if isFlagSet is true)

Solution 2: Converting Boolean to NSNumber

Another approach is to convert your Boolean flag to an NSNumber object before printing it with NSLog. You can use the NSNumber class method numberWithBool: to achieve this. Here's how you can do it:

BOOL isFlagSet = YES; // Set your Boolean flag here
NSNumber *flagNumber = [NSNumber numberWithBool:isFlagSet];
NSLog(@"isFlagSet: %@", flagNumber);

🚀 Example output: isFlagSet: 1 (if isFlagSet is true)

The Call-to-Action ✨

Printing Boolean flags in NSLog doesn't have to be a headache anymore! 🎉 Now that you have these easy solutions, go ahead and implement them in your code.
