我正在尝试制作一个使用照片浏览器的应用程序决定使用 MWPhotoBrowser。
这是代码，但我似乎无法使其工作：
视图控制器.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
视图控制器.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
我已经尝试过使用 ARC 和 wothout ARC
如果没有 ARC，我会得到 3 个错误：
架构 i386 的未定义符号： “_OBJC_CLASS_$_MWPhoto”，引用自：ViewController.o 中的 objc-class-ref “_OBJC_CLASS_$_MWPhotoBrowser”，引用自：ViewController.old 中的 objc-class-ref：未找到符号对于架构 i386 clang：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）
使用 ARC 我得到 2 个错误

问题 2 http://i.imgur.com/E0X1m.png
我还没有在这里完成，但我希望它被包裹在一个按钮中，这样我就可以单击它并在 MWPhotoBrowser 中显示图像
编辑
我已经升级了我的代码，从我的文件中删除了 ARC，现在我已经正确设置了目标。它现在会编译，但每次我尝试单击按钮时：“billede”我得到：
