I use a horizontal swipe gesture on the navigationBar to bring up an alert that contains diagnostic information.

// Boiler plate code. var target = UIATarget.localTarget(); var application = target.frontMostApp(); var mainWindow = application.mainWindow(); // Swipe gesture to bring up console. var navigationBar = mainWindow.navigationBar(); navigationBar.dragInsideWithOptions({startOffset:{x:0.0, y:0.0}, endOffset:{x:0.8, y:0.10}, duration:0.1});

Fortunately there are some definitions provided by Apple to help identify what the code is targeted for.

#if TARGET_IPHONE_SIMULATOR // Code for simulator. #else // Code for device #endif

Reference: wiki

// Boiler plate code. var target = UIATarget.localTarget(); var application = target.frontMostApp(); var mainWindow = application.mainWindow(); var keyBoard=application.keyboard(); var keys = keyBoard.keys(); keys.firstWithName("g").tap(); target.delay(0.5); keys.firstWithName("o").tap(); target.delay(0.5); keys.firstWithName("r").tap(); target.delay(0.5); keys.firstWithName("d").tap(); target.delay(0.5); keys.firstWithName("o").tap(); target.delay(0.5);

The easiest way to change this is to use the *defaults* app to write to the Xcode config:

defaults write com.apple.Xcode PBXCustomTemplateMacroDefinitions '{ORGANIZATIONNAME="Gordon Turner";}'

Works with Xcode 3.2.6.

In those situations, you will need to ‘pass a message’ to the object:

po (int)[textField superview]

Even then, there are occasions where you will have to use a selector:

print (int)[receivedData performSelector:@selector(count) ]

And finally, use a selector with an object as an argument:

print (int)[receivedData performSelector:@selector(count) withObject:myObject ]

Wireshark is my new Toy. Let me tell you why.

Ever try to save a Youtube video?

Save a streamed song or lecture?

In Canada, both actions usually are protected as long as it is for private or personal use. Practically, saving flash embedded content is a pain.

Aside It is possible to examine the browser cache directory or install plugins to intercept the embedded content. If that works for you great.

That is where Wireshark comes in. It is a cross platform network protocol analyzer based on Ethereal.

What does that really mean? Well it lets you examine the traffic coming into your computer, including the embedded content.

First grab Wireshark here: http://www.wireshark.org/

Next, install it and fire it up.

The following are instructions for capturing video from Youtube:

1. Start capture on network card.
2. Navigate to youtube video page, wait for video to completely load into the cache.
3. Stop caputure on the network card.
4. In the ‘Filter:’, paste ‘frame.len == 1434′, this should match the length of the segments of the video as it was downloading.
5. Right click on one of the segments and click on ‘Follow TCP Stream’.
6. This will assemble the TCP stream of the video with the headers.
7. Click on the ‘Save As’ and save locally.
8. Open a editor, like textpad and strip all the headers out of the top of the file.
9. Test it in a player like vlc.

Similar steps are required for flash files.
