liquid null check
In Objective-C, you can perform a null check using the !=
operator to compare a variable to nil
. Here's an example:
if (myVariable != nil) {
// Code to execute if myVariable is not nil
} else {
// Code to execute if myVariable is nil
}
This code checks if the variable myVariable
is not equal to nil
. If it is not nil
, the code inside the first block will be executed. Otherwise, the code inside the else
block will be executed.
Please note that the code snippet provided is a general example, and you may need to adapt it to your specific use case.
