What steps will reproduce the problem?
1. I add framework and *.h from Release-simulator-iphonesimulator 
2. then I only want to test the simply demo, codes are:

exifTestViewController.h

#import <UIKit/UIKit.h>
#import "EXF.h"
@interface exifTestViewController : UIViewController {
    //lsy 110929 00:00am
    UIImage *exifImg_lsy;
    UIImageView *imgDisplayImgView_lsy;
    NSData *imageData_lsy;
}

@property (nonatomic,retain) UIImage *exifImg_lsy;
@property (nonatomic,retain) IBOutlet UIImageView *imgDisplayImgView_lsy;
@property (nonatomic ,retain ) NSData *imageData_lsy;

@end

exifTestViewController.m

#import "exifTestViewController.h"

@implementation exifTestViewController
//lsy 110929 00:00am
@synthesize exifImg_lsy;
@synthesize imgDisplayImgView_lsy;
@synthesize imageData_lsy;
- (void)viewDidLoad {

    //lsy 110929 00:00am
    exifImg_lsy = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"]];
    [imgDisplayImgView_lsy setImage:exifImg_lsy];
    NSData * uiJpeg = UIImageJPEGRepresentation (exifImg_lsy, 1.0 );
    EXFJpeg* jpegScanner = [[EXFJpeg alloc] init];
    [jpegScanner scanImageData: uiJpeg];
    //self.imageData_lsy = jpegScanner;
    NSLog(@"picture length:::%d",jpegScanner.exifMetaData.height);  
    [jpegScanner release];
    [super viewDidLoad];
}
3.then error disappeared:

The target is not iphone... And also, depending on the version, you should 
compile the library again, because this one is for armv6 only
