My iPad application supports all the orientations and it worked fine in iOS 7 as well. However in iOS 8 , launching the application in Landscape mode made my login view draw the landscape view within a portrait frame.

1、xcode版本 2、xmpp 版本: https://github.com/robbiehanson/XMPPFramework 开始导入框架：（最好先在show in finder里面建立文件夹，再把xmpp框架里的东西拷贝到刚建立的文件夹，再把这些文件夹拖入工程） 第一步：先导入Vendor里面的东西 1、先导入Vendor（这里是xmpp所依赖的第三方库）文件夹里面的CocoaLumberjack。不需要添加别的库文件，编译成功。 2、再导入 CocoaAsyncSocket（xmpp底层的网络通信所使用的库），这里需要添加两个库文件： （涉及到数据加密，和安全相关）。编译成功 3、导入kissxml（用来解析xml文件，重点！）。需要导入 libxml2.dylib，然后修改项目配置。 （a）PROJECT - BuildSetting - 搜索 sear --Search Paths - Header Search Paths--路径后面添加/usr/include/libxml2 (b)原位置搜索other，linking --other linker flags ，添加 -lxml2 （c）如果编译不成功，出现tree file not find，就在TARGETS - 搜sear - search paths 添加一句$(SDKROOT)/usr/include

I am having a mac app in which I am deleting some data from user's Home directory. My app is rejected saying the below reason. The app only finds files in the ~/Downloads folder. It would be appropriate to have the user grant access to the Home folder. So I used NSOpenPanel for asking the access from the user but I have no idea about how to give access to user's hidden folders. EDIT I have successfully enabled sandboxing for my app but now on allow button, what should I do? Please guide me on this... Any help will be highly appreciated. Thanks in advance...
