Question

When I try to NSLog my image with this;

NSLog([images description]);

this appears:

2012-06-05 10:31:38.801 Project1[1180:1a303] (
    "<UIImage: 0x9a52bb0>",
    "<UIImage: 0x9c89460>",
    "<UIImage: 0x9c9c720>",
    "<UIImage: 0x8e4ee70>",
    "<UIImage: 0x8e805f0>"
)

I’m loading my UIImage from a NSDocumentDirectory.Could someone explain whats this.

It looks like your images object is an NSArray (or similar array like object) of UIImages. When you NSLog the description of the images array it is listing the objects in the array and calling description on each of those objects. As it doesn’t make sense to get a text description of an image it instead prints the object type, in this case ‘UIImage’, and the address of the object in memory, e.g. 0x9a52bb0.

I’m not sure what you mean by “And how to make this into NSInteger?’ It doesn’t make sense to convert an image into an integer.
