I want to tell you please check the "How to define method ?", You can found in above link about multiple input method also. and this one is for naming conventions of method in Objective C?

As per above we can know that your method have same name(Signature) as getText:

In your case there are duplicated method you define which is not supported by objective C Compiler.

Hope this one helpful to you.

Simply because Objective-C doesn't support overloading. And besides it is highly recommended to include the types of the arguments in the function's name, whenever possible. Try getTextFromTextView: and getTextFromTextField: instead.

objective-C does not support method overloading, so you have to use different method names.
