objective c - Passing Progress Bar Information to the View Controller -

-

I have a class that handles downloads and provides progress information. 

  - (zero) connection: (NSURLConnection *) connection was the receipt data: (NSData *) data {[Data data received: data]; Self.recievedlength = self.recievedlength + [data length]; // calculation of progress self.progress = 0; Self.progress = ((float) received / [filesize floatValue]); // NSLog (@ "% f", auto.progress); [Self display selectorMythrthread: @Selector (Passprogress) with object: not waiting until: no];   
 I have the following selector, which gives the float's progress information int form in the same class:  
     
  •  (float) pass progress {/ NSLog (@ "% F", self.progress); Return self Progress; }   
     My question is, how can I update the UIProgressView (progress bar) in the menu widgetor. The following does not work    NSLog (@ "Progress% F", [Class Eases Pass Progress]);   
     Any thoughts please do not want to write the download code in the main code controller.   
     
     
     Write a  protocol  in your main control controller in your main view controller To adopt

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
