Objective c checking whether text field is empty
Simply checks for nil and if length of text length is greater than 0 - not empty
if (textField.text && textField.text.length > 0){ /* not empty - do something */}else{ /* what ever */}
We already have inbuilt method that return boolean value that indicates whether the text-entry objects has any text or not.
// In Obj-Cif ([textField hasText]) { //* Do Something you have text }else{ /* what ever */ }// In Swiftif textField.hasText { //* Do Something you have text}else{ /* what ever */}
Joshua has the right answer in the narrow case, but generally, you can't compare string objects using the == or != operators. You must use -isEqual: or -isEqualToString: This is because charlieImputSelf and @"" are actually pointers to objects. Although the two sequences of characters may be the same, they need not point at the same location in memory.
