I’m trying to make a app that uses a photobrowser
Decided to go with the MWPhotoBrowser.

This is the code, but i cant seem to make it work:

ViewController.h

#import <UIKit/UIKit.h>
#import "MWPhotoBrowser.h"

@interface ViewController : UIViewController<MWPhotoBrowserDelegate> {
    NSArray *_photos;
    UISegmentedControl *_segmentedControl;
}
@property (nonatomic, retain) NSArray *photos;
- (IBAction)billede:(id)sender;

@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
@synthesize photos = _photos;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        UIBarButtonItem *item = [[[UIBarButtonItem alloc] initWithCustomView:_segmentedControl] autorelease];
        self.navigationItem.rightBarButtonItem = item;
        self.navigationItem.backBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:nil action:nil] autorelease];
    }
    return self;
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (IBAction)billede:(id)sender {

    //show your photo whit url
    NSMutableArray *photos = [[NSMutableArray alloc] init];
    MWPhoto *photo;
    {
    photo = [MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:@"photo2l" ofType:@"jpg"]];
    photo.caption = @"The London Eye is a giant Ferris wheel situated on the banks of the River Thames, in London, England.";
    [photos addObject:photo];
    }

    self.photos = photos;

    // Create browser
    MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithDelegate:self];
    browser.displayActionButton = YES;

    //browser.wantsFullScreenLayout = NO;
    //[browser setInitialPageIndex:2];

    // Show
    if (_segmentedControl.selectedSegmentIndex == 0) {
        // Push
        [self.navigationController pushViewController:browser animated:YES];
    } else {
        // Modal
        UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:browser];
        nc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
        [self presentModalViewController:nc animated:YES];
        [nc release];
    }



}


#pragma mark - MWPhotoBrowserDelegate

- (NSUInteger)numberOfPhotosInPhotoBrowser:(MWPhotoBrowser *)photoBrowser {

    return _photos.count;

}



- (MWPhoto *)photoBrowser:(MWPhotoBrowser *)photoBrowser photoAtIndex:   (NSUInteger)index {

    if (index < _photos.count)

        return [_photos objectAtIndex:index];

    return nil;

}

@end

I’ve tried both with ARC and wothout ARC

Without ARC i get 3 errors:

Undefined symbols for architecture i386:
“_OBJC_CLASS_$_MWPhoto”, referenced from:
objc-class-ref in ViewController.o
“_OBJC_CLASS_$_MWPhotoBrowser”, referenced from:
objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

With ARC i get 2 errors

Problem 2

I’ve not done it here, but i would like it alle to be wrapped in a button so i can click that and show a image inside the MWPhotoBrowser

Edit

I have upgraded my code, removed ARC from my files and i have now set the target right.
It will compile now, but everytime i triy to click the button: “billede” i get:

    Actually resolved this.
    I’ve struggled for 4 days and finally got it.
    I read through https://github.com/mwaterfall/MWPhotoBrowser#method-1-static-library and understood it, finally but i had a problem with User header Search Path.
    I finally got it, importet MWPhotoBrowser folder into my MWPhotoBrowser”project” folder and then sat User Header Search Path to “..” instead of “../” since “../” gave me “../../“

    Hope this helps anyone who might stand in the same problem as me!

    Btw, thanks for the help guys! 🙂
