Question

_imgIndex.text = [@(index+1) stringValue]; //how to add string here?

Answer 1

It appears that you have an integer value (index) and a Obj-C string object (stringValue) and you want to concatenate them. There are lots of ways of doing this, here are two:

_imgIndex.text = [NSString stringWithFormat:@"%lu%@",index,stringValue];

The other technique would be to first convert the integer into a string, then concatenate the other string:

_imgIndex.text = [@(index).description stringByAppendingString:stringValue];
