将文件复制到剪贴板

Question

大家好！有人知道如何实现这个吗？我的意思是：如果我想将一个字符串放到剪贴板中，我该怎么做？

NSPasteboard *pboard = [NSPasteboard generalPasteboard];
[pboard declareTypes:[NSArray arrayWithObject:NSPasteboardTypeString] owner:self];
[pboard setString:@"aString" forType:NSPasteboardTypeString];

但是如果我想将文件放入剪贴板怎么办？我想找到一种方法，使用文件路径作为参数，然后能够通过上下文菜单或CMD-V在Finder中将该文件粘贴到任何地方。

有人可以帮帮我吗？

非常感谢！

在经过数个小时的搜索后，我终于得到了一个简短的答案...

NSArray *fileList = [NSArray arrayWithObjects:filePath1, filePath2, nil];
NSPasteboard *pboard = [NSPasteboard generalPasteboard];
[pboard declareTypes:[NSArray arrayWithObject:NSFilenamesPboardType] owner:nil];
[pboard setPropertyList:fileList forType:NSFilenamesPboardType];

我快速地把这个东西组合在一起，但是已经使用CMD+V和上下文粘贴进行了测试。

NSURL *object = [[NSURL alloc] initFileURLWithPath:@"/Users/username/Desktop/main.png"];
NSPasteboard *pb = [NSPasteboard generalPasteboard];
[pb clearContents];

NSArray *objectsToCopy = [[NSArray alloc] initWithObjects:object, nil];
BOOL pasted = [pb writeObjects:objectsToCopy];

if(pasted) // paste was successful
    NSLog(@"pasted");

[object release];
[objectsToCopy release];
[pb release];

我没有尝试过这个，但据我理解文档，你所要做的（至少在OS X 10.6+中）就是这样：

NSURL *fileURL = [NSURL fileURLWithString:...];
NSPasteboard *pasteboard = [NSPasteboard generalPasteboard];
[pasteboard writeObjects:[NSArray arrayWithObject:fileURL]];

从剪贴板读取URL：

NSArray *urls = [pasteboard readObjectsForClasses:[NSArray arrayWithObject[NSURL class]]
                                          options:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:NSPasteboardURLReadingFileURLsOnlyKey]];
if ([urls count] == 1) {
    NSURL *myFileURL = [urls objectAtIndex:0];
    ...
}
