在我的应用程序中使用了https://github.com/mwaterfall/MWPhotoBrowser库.. 但我无法分配图像 url 如何分配图像 url。请解决我的问题请检查我的代码：
-(NSUInteger)numberOfPhotosInPhotoBrowser:(MWPhotoBrowser *)photoBrowser
{
return _photos.count;
}
- (MWPhoto *)photoBrowser:(MWPhotoBrowser *)photoBrowser photoAtIndex:(NSUInteger)index
{
if (index < _photos.count)
return [_photos objectAtIndex:index]; return nil;
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableArray *photos = [[NSMutableArray alloc] init];
// photos=[[NSMutableArray alloc]initWithObjects:@"1.jpg",@"2.jpg",@"3.png", nil];
photos=[[NSMutableArray alloc]initWithObjects:@"http://www.google.co.in/imgres?imgurl=https://alaskabibleteacher.files.wordpress.com/2014/09/apple-tree.jpg&imgrefurl=http://brokenbelievers.com/2014/09/19/the-apple-tree/&h=606&w=808&tbnid=uY1OY_HyQ8hE1M:&docid=vKsOHUHBZ2CVFM&ei=1mXuVcu1O8rbuQTW_7Z4&tbm=isch&ved=0CDEQMygBMAFqFQoTCMv4zcvO5scCFcptjgod1r8NDw",@"http://www.apple.com/ipad/home/images/social/og.jpg?201508031746", nil];
for (int i = 0; i < photos.count; i++)
{
[photos addObject:[MWPhoto photoWithURL:[NSURL URLWithString:photos[i]]]];
}
_photos = photos;
MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithDelegate:self];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:browser];
[browser showNextPhotoAnimated:YES];
[browser showPreviousPhotoAnimated:YES];
[self presentViewController:nc animated:YES completion:nil];
}
我更新了我的代码和错误... 我收到一个错误： [MWPhoto length]: unrecognized selector sent to instance 0x7febf97f4740 2015-09-08 10:43:16.231 Salon[3926:66068] *** 由于未捕获的异常而终止应用程序'NSInvalidArgumentException'，原因：'-[MWPhoto 长度]：无法识别的选择器发送到实例 0x7febf97f4740'
