How to print a single array element in Objective-C?

Question

Hello,

How to print a array element at particular index in Objective-C?My code looks like this,

NSString *String=[NSString StringWithContentsOFFile:@"/User/Home/myFile.doc"];
NSString *separator = @"\n";
NSArray *array = [String componetntsSeparatedByString:separator];
NSLog(@"%@",array);

I'm able to print full contents of array at once, but i want to assign element at each index into a string, like...

str1=array[0];
str2=array[1];
str3=array[0];...this continues

how to do this??

You want the objectAtIndex: method. Example:

NSString *str1 = [array objectAtIndex:0];
NSString *str2 = [array objectAtIndex:1];
NSString *str3 = [array objectAtIndex:2];

From the documentation:

objectAtIndex:
Returns the object located at index.

- (id)objectAtIndex:(NSUInteger)index

Parameters
index
An index within the bounds of the receiver.

Return Value
The object located at index.

Discussion
If index is beyond the end of the array (that is, if index is greater than or equal to the value returned by count), an NSRangeException is raised.
