Today just upgraded Xcode7, built-in the latest version of the iOS9 SDK, wrote a small demo to find the image can not be downloaded, while the system printout:
APP Transport Security has blocked a cleartext HTTP (/HTTP) resource load since it is insecure. Temporary exceptions can be configured via your app ' s info.plist file.
A look at this HTTP I think of the apple in the iOS9 began to use a more secure HTTPS protocol, and now most of the company's server estimates are not upgraded to this, which led to the failure of the download, iOS9 by default is HTTPS, but can also be set to tell the system we also use HTTP, Here's how:
Search in Filter Info.plist , select Info.plist to edit
According to the above-mentioned way to add information, the correct changes will see this look, note the type NSAppTransportSecurity Dictionary , NSAllowsArbitraryLoads for Boolean , copy and paste, do not have more space, segment fault page directly copied, often more one out of space!
Note that there is also a unit test below Info.plist , it is not useful to modify that file!
With the above settings can be the same as the previous use of HTTP, but the personal feeling is not server-side updates, support HTTPS or more secure ...
