Replace a substring with another substring

Question

I want to replace the string "abc" to "def" each time it appears in my NSString object: "axcd abc amamam dff abc kdj abc"

How do I do that??

Thanks,

Sagiftw

For future reference, spaces between tags represents different tags. I've fixed it for you, but the proper objective C tag is "objective-c". — Dave McClelland

Try stringByReplacingOccurrencesOfString:withString:.

NSString* foo = @"axvc abc amamam dff abc kjd abc";
NSString* bar = [foo stringByReplacingOccurrencesOfString:@"abc" withString:@"def"];
NSLog("%@", bar);

@KaranAlangat, are you sure about that? The documentation says that it's still available and not deprecated, both in the iOS sets and OS X sets.

@zneak It s a mistake from me. I did check in my Xcode a lot of time and it didn't work for me. Now a days my Xcode shows unwanted errors even in blank lines. It works fine .
