带按钮和错误处理的MWPhotoBrowser

Question

我正在尝试制作一个应用程序，它使用的是一个决定与MWPhotoBrowser一起使用的照片浏览器。

这是代码，但我似乎无法让它工作：

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

我试过ARC和wothout ARC

如果没有ARC，我会得到3个错误：

未定义的体系结构符号："_OBJC_CLASS_$_MWPhoto"，引用自: objc-class-ref in ViewController.o "_OBJC_CLASS_$_MWPhotoBrowser"，引用: objc-class-ref in ViewController.ld:符号(S)未找到用于体系结构的i386 clang: i386：链接器命令失败，退出代码1(使用-v查看调用)

有了ARC，我得到了两个错误

问题2 http://i.imgur.com/E0X1m.png

我没有在这里做过，但是我希望它能被一个按钮包裹起来，这样我就可以点击它，在MWPhotoBrowser中显示一个图像。

编辑

我已经升级了我的代码，从我的文件中删除ARC，现在我已经设置了目标正确。它现在将编译，但是每次我试着点击按钮："billede“，我得到：

Answer 1

实际上解决了这个问题。我挣扎了4天终于拿到了。我阅读了https://github.com/mwaterfall/MWPhotoBrowser#method-1-static-library并理解了它，但我在用户头搜索路径上遇到了问题。我终于得到了它，将MWPhotoBrowser文件夹输入到我的MWPhotoBrowser“项目”文件夹中，然后坐在用户头上搜索路径到“.”而不是“./”，因为“./”给了我“././”

希望这能帮助那些可能和我站在同一个问题上的人！

顺便说一句，谢谢你们的帮助！

Answer 2

附件1:不能将对象添加到NSArray，而是使用NSMutableArray。

附件2: UIView没有"reloadData“方法，但是UITableView有。
