Understanding the basics of uncaught exception nsinvalidargumentexception

When developing an app, encountering errors is inevitable. One type of error that can cause an app to terminate unexpectedly is an uncaught exception. An uncaught exception is an error that occurs during runtime and is not handled by the app's code. One common type of uncaught exception is an NSInvalidArgumentException.NSInvalidArgumentException is an Objective-C exception that is thrown when a method is called with an invalid argument value. This means that the argument passed to the method is not of the expected type or does not meet certain requirements. When this happens, the app will terminate with an error message indicating that an uncaught exception has occurred.

What causes the termination of an app due to nsinvalidargumentexception?

The main cause of an app termination due to NSInvalidArgumentException is the passing of an invalid argument value to a method. For example, if a method expects an integer value but receives a string, an NSInvalidArgumentException may be thrown. Another common scenario is when a method expects a non-nil object but is passed a nil value.Other causes of NSInvalidArgumentException include passing an argument with an out-of-range value or using a deprecated method. In some cases, the error may be caused by a bug in the app's code or a third-party library.

The role of invalid argument values in triggering an uncaught exception

Invalid argument values are the main trigger for NSInvalidArgumentException. When a method is called with an invalid argument value, the app's code may not be able to handle the error, leading to the exception being thrown.
