Passing float "byref" in Objective C? -


Is there a way to pass a float by "byref" by a method in Objective-C? I have an overview of what I have:

Method Signature: 

  - (zero) MerryPad: (Float *) Minimum Max: (Float *) Max;

Method: 

  - (zero) MyMethod: (float *) minimum maximum: (float *) max {}

Try applying it: 

  float min1 = 0; Float max 1 = 0; [Myself Method: Minimum: Maximum 1 Max: & amp; Maximum 1];

I get the following warning, and the code flows when trying to implement MyMethod:

Warning: 'MyClass': MyMethod: min: max: 

  -   
 
 
 The signature for your method has been announced < / P> (empty) MyMethod: (Float *) Minimum Max: (Float *) Maximum

But you can call it 

  - MyMethod: min: max :

... which contains an extra 'min:' which is not in the declaration.

Try changing your calling code 

  float min 1 = 0; Float max 1 = 0; [Self Mymath & amp; Min 1 Max: & amp; Max 1];

And see if things improve.

However, I see that your error message complains about the signature '+ MyMethod: min: max:', which also suggests you class class < I-> Example instead of trying to send the message; You have to improve it.

Finally, in Objective-C code, the method selector usually starts with a lower case; You may want to read on normal.
