Unity Upgrade 2017.2 and above

Hello  Unity Developers , Recently, I faced few issues with Unity Editor and I hope sharing it will help. What was I trying to do? Scenario? Upgrading to Unity 2017.2 & Unity 2017.3 I was trying to upgrade one of my project from Unity 2017.1.2 version to Unity 2017.2.1f1. On doing so, usually unity automatically updates the obsolete scripts to support new APIs. Once it got updated, I tried to play the game in editor and it worked. Then, what was the problem? While building the project to UWP application, there were some compile errors where Unity.VR need to be updated to Unity.XR. I fixed those errors, quit unity and tried building again.  Wait, Why did I quit Unity and then built it again? Its because unity has this weird issue, when there are compiler errors. Though I had fixed the errors, on building it again, the errors will not go away. We have to quit unity and then build it, TADA, the error will go away. Now coming back to other issues I fa

Copying Multiple Content Simaltaneously

We often used to thank   Larry Tesler    for his splendid invention "Cut/Copy/Paste". Think of the world without copy/paste :o :o :o Have you ever tried copying non-sequential content? Ctrl+v will paste the last copied content in the clipboard, whereas ctrl+c copies the content that are selected sequentially   to the clipboard. What if I wanted to copy multiple content from multiple web pages and pasting it in one go, instead of pasting one by one? Or without using paste command copy the multiple content directly to a file? Here is the solution for the Mac Users. [Windows user? Working on it. Will update asap ;) ]   Follow the steps below, which takes less than five minutes and save several minutes ;) 1)     Launch “Automator” 2)     Choose “Utilities” in the left pane 3)     Double Click “Run Shell Script” 4)     The “Run Shell Script” will be added to the right pane. 5)     Add the following script in the script content.

Percent Escape the reserved Characters in URI

URI encoding need to be done when performing network API calls based on RFC 3986. In order to encode any character, the following native method can be used: [uriString stringByAddingPercentEncodingWithAllowedCharacters : [ NSCharacterSet URLQueryAllowedCharacterSet ] ] But the above method is not compliant with RFC3986 and it does not encode the reserved characters like "!*'();:@&=+$,/?%#[]". Hence, the following method can be used for percent encoding the specific reserved characters. ((NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL, (__bridge CFStringRef) string, NULL,  CFSTR("!*'();:@&=+$,/?%#[]"), encoding))); }

#iOS8 #XCode6 #SizeClasses

       In Xcode 6, new feature called "Size classes" have been introduced. The size classes are used for making the storyboard compatible for all iOS Devices(iPhone & iPad, even iPod) in both portrait as well as Landscape orientations. To set the size class: 1) Choose "Universal" option while creating the project. 2) Check the auto layout checkbox in Main.storyboard -> File Inspector -> "Use Auto Layout" 3) Check the size classes check box in Main.storyboard -> File Inspector -> "Use Size Classes". There are two types of size classes: Regular and Compact. Hence the different configurations(screen sizes) include, 1) wAny hAny - Base configuration 2) wCompact hRegular - iPhone Portrait 3) wCompact hCompact - iPhone Landscape 4) wRegular wAny - iPad Landscape and portrait On selecting the base configuration, the storyboard works the same in all devices. This can be viewed in "preview" option in the assis

Collection View - 2D Display

/*Nothing but dividing items into number of columns and rows */ sizeForItemAtIndexPath() It returns the size for each item. In collection view, each cell is considered as item and not as rows or columns. To make it 2D(columns and rows), distribute the collection view frame size into several item sizes, in such a way that x number of items can be placed in a single row. For instance, if there are 50 items( 5 items in each row which is nothing but 5 columns in 1 row and there are 10 such rows).   Given collection view frame size is 1000. Now this can be done by dividing the frame size by number of columns,   i.e., 1000/5 = 200. So each items width will be 200.

Container View - Multiple View Controllers

       By default, Each Container View can have one child view controller only. Only one controller can be added to container using "Embed segue".       In order to add multiple view controller,  the following may help:      Use a separate container view controller and add it using embed segue to the container view. Now from the container view controller that is created, perform transition to different child view controllers using custom segues.

Separator Inset Problem - iOS 8

                    In iOS8, there is extra space in table view separators by default. It is nothing but the edge inset. To remove the separator edge inset, in iOS 7, custom separator insets can be set in the attributes inspector of the table view. In iOS 8, use the following in the table view controller: //set edge inset zero for default separator -(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath     {     if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {     [self. tableView setSeparatorInset:UIEdgeInsetsZero];   }     if ([self. tableView respondsToSelector:@selector(setLayoutMargins:)]) {     [self. tableView setLayoutMargins:UIEdgeInsetsZero];   }     if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {     [cell setLayoutMargins:UIEdgeInsetsZero];   } }
