Check whether a string contains substring.
Turns out that the Foundation Framework does not have this nifty little utility to check whether a string contains a substring. But this can be easily done manually:
-(BOOL)string:(NSString*)string1 containsString:(NSString*)string2{
NSRange rangeValue = [string1 rangeOfString:string2 options:NSCaseInsensitiveSearch];
if (rangeValue.length > 0){
return TRUE;
}
else {
return FALSE;
}
}
