Reading binary file into array in Objective-C [iPhone]

I want to read binary file on my iPhone. I have .txt file which stores information about an array: int[6000][9] How can I put this data into an array in my code?

I tried this:

int mapa1[6000][9];

NSFileHandle*开发者_如何学编程 file = [NSFileHandle fileHAndleForReadingAtPAth: @"level1.txt"];
[[file readDataOfLength:4] getBytes:mapa1];
mapa1 = NSSwapLittleIntToHost(mapa1);

But on the last line I receive error: "Incompatible types in assigment" So I don't know how to copy this binary file into the array...

Can someone help me?

mapa1 is not an unsigned int, which is what the returnvalue of NSSwapLittleIntHost is.
