core location - Where to implement CLLocationManager -

-

I have a tab bar and 3 tab app, the user's current location is known to any of the three tabs must have. In this case will the app be the best place to implement CLLocationManager in the app?

Is it OK (good practice?) CLLocationManager delegation methods to put in App rep M file?

Where do you say that I am calling CLLocationManager as a place from any of the three tabs I am using -startUpdatingLocation ?

Thank you

App representative is an appropriate place to put it. Another option is to create a custom singleton factory class that contains a class method that returns to your location manager representative and applies the methods of the representative there. This will maintain your app representative class cleaner.

Here is a skeleton singleton class implementation based on Peter Hussie. It can be overkill, but it's a beginning. Finally add your representative methods.

Fixed MyCLLocationManagerDelegate * sharedInstance = Zero; + (Zero) start {if (Shared Instance == zero) Shared Instance = [[Autonomous] init]; } + (ID) sharedMyCLLocationManagerDelegate {// is already defined + start return share instance; } + (Id) allocWithZone: (NSZone *) area {// usually pre-defined + start @ synchronize (self) {if (shared instance) {// caller is expected to get a new object, then the last To save the release message in a manner, put it on // Returns [Maintain shared instances]; } Else {// when not already set, + starting is our collar // it's making a common example, let it go.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
