iOS thread error when reading from a text file - ios

Question

I'm trying to print an individual element of an array from a text file, here is the code I'm using :
//Tells the compiler where the text file is and its type
NSString* path = [[NSBundle mainBundle] pathForResource:#"shakes"
ofType:#"txt"];
//This string stores the actual content of the file
NSString* content = [NSString stringWithContentsOfFile:path
encoding:NSUTF8StringEncoding
error:NULL];
//This array holds each word separated by a space as an element
NSArray *array = [content componentsSeparatedByString:#" "];
//Fast enumeration for loop tha prints out the whole file word by word
// for (NSString* word in array) NSLog(#"%#",word);
//To access a certain element in an array
NSLog(#"%#", [array objectAtIndex:3
]);
The problem is - if I wish to access the first 2 elements, 0 or 1, that is fine. However, as soon as I wish to access say, element 2 or 3 I get the following error :
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 3 beyond bounds [0 .. 1]
It is a SIGABRT threading error - something which seems to crop a lot in iOS programming, but it's normally quite solvable.
The text file "Shakes.txt" is 6 elements long and is only really for testing purposes.
PS - The third line is commented out just incase I want to use it later... So don't worry about that.
Thanks in advance for any help!

Basically you are trying to access an object which is out of bounds of the array.
The log is very obvious your array only has 1 element and you are trying to access the 4th one.
Add this to your code.
NSMutableArray *contentArray = [[NSMutableArray alloc] init];
for (NSString* word in array)
{
[contentArray addObject:word]
}
//Now try to access contentArray
NSLog(#"%#", [contentArray objectAtIndex:3
]);
