iphone - How much contentOffset changes in UIScrollview for zooming? -

-

In UIScrollview, when I scroll / drag, I have changed the ScrollView content which shows how many scrolls / Was dragged scrollview. In this way, I have updated the scrollviewsview for scrolling.

However, when I zoom in ScrollView (using pinch zooming), the offset of content scrollwatch also changes. I do not understand how much content offset has changed because I can not relate the changes with the zoomscale value to know the changes in the content for zooming anyway?

My intention is to get the value of the material to change while zooming (which is not because I get the material offset change due to zooming) so that I update the subview of my scrolls accordingly You can.

I got stuck in here. Any help will be very much appreciated.

Thanks

I have set up A small test project, and it looks like content offset is multiplied by zoomScale . So if you want to account for it, before using it, divide it with zoomScale

Perhaps it is best to describe it with a short example: I have a scrollview , And added a scene that pans around the pan and zooms a little zoom. For that scene, I've added a little red view, which I want to keep in the same situation, no matter whoever it is. I'm looking at the content offset of ScrollView, and I've implemented it like this: CGPint ContentForce = Self. Scrollviewconsetset; CGFloat zoomscackel = self.scrollView.zoomScale; Self.moveView.frame = CGRectMake ((contentOffset.x + 10) / zoomcale, (contentOffset.y + 10) / zoomscale, 10, 10);

It puts moveView in the same position on the screen, when the user zooms, then scaling.

I hope this clears one thing, but if I can do it for help, then I know.

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>
