ios - I need to get the referencing outlet, or some other identifier from the sender (UITextView) -

warning: new ios development not coding in general.

i trying validation on uitextview, several actually. have different requirements length. have created custom delegate handle running issue figuring out how make unique textview sending it.

i have several fields in several different nibs make use of delegate. of nibs have 3 textviews labeled like: summary, detail , special instructions. each of these has different max length 50, 100, 130 respectively.

tl:dr; how can unique id each sender can switch on them?

edit: update label, hidden until needed, count down available chars left. how make sure accessing correct controller , label?

in delegate protocol, define way send uitextview instance along else, like:

@protocol uitextfieldvalidationdelegate  - (bool) textfield:(uitextfield)tf textforvalidation:(nsstring *)newtext;  @end 

so when uitextfields call this, pass in inspection delegate:

bool valid = [self.delegate textfield:self textchanged:newtext]; 

in delegate, you'll implement as:

- (bool) textfield:(uitextfield)tf textforvalidation:(nsstring *)newtext {     //compare iboutlets     if (tf == self.tfphonenumber)     {        //do phone number validation     }     else if (tf == self.tfemail     {        //do email validation     }       if (valid)     {         return yes;     }     else     {         return no;     } }
