Private browsing with UIWebView on the iPhone & iPad -

-

How do the existing apps apply this feature ???

Can I only store cookies for some sites, and only inside my app? It's my understanding that web views store cookies in shared mode ... so that they can be shared with other apps that use Safari and UIWebView.

NSHTTPCookieStorage , cookies are not shared between applications:

iPhone OS Note: Cookies are not shared between applications in the iPhone OS.

It seems that they should be "private" by default. You can also use [NSHTTPCookieStorage sharedHTTPCookieStorage] to set cookie storage policy to not store all cookies on an object, or you can use deleteCookie: If you need to clean the method after yourself.

Other content is loaded with your UIWebView when you create NSURLRequest that is loaded with your webview, as you can determine if a cache policy content will be accumulated. For example: 

  NSURLRequest * request = [NSURLRequest requestWithURL: [NSURL URLWithString: URL] cachePolicy: NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval: 60.0] [WebView loadRequest: request];

NSURLRequestReloadIgnoringLocalAndRemoteCacheData tells the request to ignore the cache and load the request from the network. I'm not sure if this also protects the network from being cached, but be sure that you can alway remove it from your own: 

  [NSURLCache sharedURLCache] removeCachedResponseForRequest: request];

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
