Search an NSMutableArray with strings if string is equal to other string NLog position of item - objective-c

Question

I have an NSMutableArray with items in it.
I would like to compare every item with a string.
If the string is the same then the next item of the array should be stored in another array.
NSString *string2 = [NSString stringWithFormat:#"Period:"];
// Filtern nach Periode
NSMutableArray *Eventarray =[NSMutableArray array];
for(int i=0;i<[lines count]; i++)
{
NSMutableString *string1 = [NSMutableString stringWithFormat: #"%#",[[lines objectAtIndex:i]description]];
// NSLog(#"%#",string1);
int index = [[lines objectAtIndex:i] indexOfObject:#"Period:"];
NSLog(#"%#",index);
if ([[lines objectAtIndex:i] isEqualToString:#"Period:"])
{
//strings are same
NSLog(#"ii");
NSLog(#"ii");
int e=i+1;
NSMutableString *Periode = [NSMutableString stringWithFormat: #"%#",[lines objectAtIndex:e]];
[Eventarray addObject:Periode];
}
[string1 deleteCharactersInRange:NSMakeRange([string1 length]-1, 1)];
}
for(int i=0;i<[Eventarray count]; i++)
{
NSLog(#"Eventarray: %#", [Eventarray objectAtIndex:i]);
}
The array looks like this:
2013-08-12 13:31:35.375 xxxx[3809:207] PublishedRoster
2013-08-12 13:31:35.376 xxxx[3809:207] Period:
2013-08-12 13:31:35.377 xxxx[3809:207] 25Jul2013-08Sep2013
I tried everything but I don't know whats wrong. What am I missing?

Try using NSRange
If you want to search for a substring
NSString *homebrew = #"Rajneesh071";
NSRange range = [homebrew rangeOfString:#"Raj"];
// Did we find the string "Raj" ?
if (range.length > 0)
NSLog(#"Range is: %#", NSStringFromRange(range));
In your code you can do it like.
for(int i=0;i<[lines count]; i++)
{
NSRange stringRange = [[lines objectAtIndex:i] rangeOfString:#"Period:" options:NSCaseInsensitiveSearch];
if(stringRange.location != NSNotFound)
{
[Eventarray addObject:Periode];
}
}
