I have two strings both with value null. But when I am comparing the string I have some problem : if([textField.text isEqualToString:str]) { //Some code } Both are null but control does not get into if condition. Please help.

[nil anyMethodName] always returns zero/NO. You need to compare with == to handle the null case (but still compare with some form of isEquals to handle the non-null case).
