TPTimeoutURLConnection

DESCRIPTION

In iOS 5 or below, there are a special specification that when HTTPBody is set to a NSURLRequest instance, the timeoutInterval is reset to 240 sec( see:https://devforums.apple.com/message/108292/). This specification is not written in API document definitely.

You cannot reset the timeoutInterval under 240 sec if you create NSMutableURLConnection instance.

To avoid this specification, you should invoke a timer, and cancel the connection by yourself.

This tiny library add a category which treats timer and cancel tasks in synchronous connection. This library also adds sample implementation for asynchronous connection.

In iOS 6 environment, this specification was changed and the timoutInterval will not be changed if you set HTTPBody value.

PLATFORM

iOS 5 and above. This library may be run in OS X environment, but I've not tested.

You have to enable ARC.

This library my be run under iOS6 environment, but the OS changed timeoutInterval specification, so you don't need to use it anyway.

PREPARATION

If you'd like to use synchronous connection, please copy URLConnection+TPTimeoutSync.h and URLConnection+TPTimeoutSync.m to your project.

If you'd like to use asynchronous connection, please copy TPURLConnection.h and TPURLConnection.m files. Then you should implement some methods for your delegate with seeing TPURLConnectionDelegate.h and TPURLConnectionDelegate.m.

USAGE

For synchronous connection, this library adds TPTimeoutSync category to NSURLConnection and provides sendSynchronousRequest:timeoutInterval:returningResponse:error: method.

The specification is same as sendSynchronousRequest:returningResponse:error: of NSURLConnection, but you can provide timeout value with timeoutInterval argument as NSURLRequest in a similar way.

For asynchronous connection, this library provides TPURLConnection class, which inherits NSURLConnection. This class adds initWithRequest:timeoutInterval:delegate: and initWithRequest:timeoutInterval:startImmediately: methods. Both method are as same as NSURLConnection's one, but you can set timeoutInterval.

If you use this class, you have to invalidate a timer, which is for checking timeout, in your delegate. You should check TPURLConnectionDelegate class for implementation details.

You should take care that the timeout value which is originally set to NSURLRequest might be changed by iOS when you set HTTPBody to NSURLRequest.
