我想创建一个连接到 iPhoto 图库的应用程序。所以现在我想从图书馆阅读事件和图片本身。
是否有一种优雅/简单的方法来执行此操作,还是我必须手动读取 iPhoto 用户数据的捆绑结构?
到目前为止我只找到了一个拍照者:Is there a UIImagePicker for the Mac Desktop
更新:我找到了另一个相关的 SO 帖子:Selecting iPhoto images within a cocoa application
最佳答案
你可以用 NSAppleScript 做到这一点。这是从我的应用程序中复制/粘贴的一些内容,经过一些改动只是为了展示这个想法。
NSAppleEventDescriptor d = .. compile this script ..
@"tell application \"iPhoto\" to properties of albums"
for (int i = 0; i < [d numberOfItems]; i++)
{
NSAppleEventDescriptor *albumDesc = [d descriptorAtIndex:i];
// <NSAppleEventDescriptor: 'ipal'{
// 'ID ':4.265e+09,
// 'purl':'utxt'("http://www.flickr.com/photos/..."),
// 'pnam':'utxt'("Vacation"),
// 'alTy':'pubs',
// 'alCh':[ ],
// 'alPx':'msng' }>
NSString *albumName = [[albumDesc descriptorForKeyword:'pnam'] stringValue];
NSString *albumId = [[albumDesc descriptorForKeyword:'ID '] stringValue];
你可以做同样的事情来找到图片
NSString *scp =
[NSString stringWithFormat:@"tell application \"iPhoto\" to properties of photos of album id %@",
[album objectForKey:@"id"]];
NSAppleEventDescriptor *d = ... compile scp ...
// 1 based!?
for (int i = 1; i <= [d numberOfItems]; i++)
{
NSAppleEventDescriptor *photoDesc = [d descriptorAtIndex:i];
// Yes.. this happens. Not sure why?!
if (!photoDesc)
continue;
// <NSAppleEventDescriptor: 'ipmr'{
// 'pnam':'utxt'("IMG_0058.JPG"),
// 'pwid':768,
// 'pdim':[ 768, 1024 ],
// 'alti':1.79769e+308,
// 'filn':'utxt'("3133889525_10975ba071_b.jpg"),
// 'ipth':'utxt'("/Users/lagnat/Pictures/iPhoto Library/Masters/2010/11/10/20101110-002341/3133889525_10975ba071_b.jpg"),
// 'idat':'ldt '($F57C69C500000000$),

// 'ID ':4.295e+09,

NSString *path = [[photoDesc descriptorForKeyword:'ipth'] stringValue];
NSString *imgname = [[photoDesc descriptorForKeyword:'pnam'] stringValue];
