iOS：UIPasteboard setImage：在iOS6和/或Xcode 4.5上失败 [英] iOS: UIPasteboard setImage: fails on iOS6 and/or Xcode 4.5

问题描述

更新：在Apple网站上添加了错误12408800.

Update: Added bug 12408800 on Apple's site.

我正在复制一个或多次UIImage到UIPasteboard，它一直在工作，直到我的手机升级到iOS 6。

I am copying some one or multiple UIImage to the UIPasteboard, and it's been working like gangbusters.. until my phone upgraded to iOS 6.

• Xcode 4.5 with iOS 5.1 - 确定


• Xcode 4.4 with iOS 6.0 - 也行OK （根据这篇文章 ）


• Xcode 4.5 with iOS 6.0 - FAIL

• Xcode 4.5 with iOS 5.1 - OK
• Xcode 4.4 with iOS 6.0 - Also OK (according to this post)
• Xcode 4.5 with iOS 6.0 - FAIL

（还测试了通过TestFlight分发，它的价值 - 仍然失败）

(also tested distributing via TestFlight, for what it's worth - still fails)

这是我的代码（超级基本等）：

Here's my code (super basic, etc):

// add image to clipboard
UIImage *image = [[UIImage imageNamed:@"testimage"];
[[UIPasteboard generalPasteboard] setPersistent:YES];
[[UIPasteboard generalPasteboard] setImage:image];

以下是当我尝试粘贴MMS / iMessage窗口时会发生的情况（对不起巨大的屏幕截图） ;视网膜显示..）：

And here is what happens when I try to paste in an MMS/iMessage window (sorry for huge screenshot; retina display..):

..以及iOS6模拟器中的Messages示例应用程序失败的示例（请参阅两个问号..？）：

..and an example of a failure on the Messages sample app in the iOS6 simulator (see the two question marks..?):

就像我说的，上面的代码已经工作了很长时间，所以我确定这是新的东西。

Like I said, the above code has been working for ages, so I'm sure this is something new.

有什么想法吗？在链接的帖子中，作者建议重新编译旧版本的Xcode - 但这不会导致其他iOS6库停止工作吗？

Any thoughts? On the linked post, the author suggests re-compiling on an old version of Xcode - but wouldn't that cause other iOS6 libraries to stop working?

推荐答案

这适用于我的iOS 6设备的Xcode 4.5。

This works for me on Xcode 4.5 for my iOS 6 devices.

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];        
NSData *imgData = UIImagePNGRepresentation(@"image");
[pasteboard setData:imgData forPasteboardType:[UIPasteboardTypeListImage objectAtIndex:0]];
