Load SVG images in iPhone / iPad using Objective C

You might have struggled a lot to load SVG (Scalable Vector Graphics)  image(s) in your iPhone or iPad application using Objective C XCode. Objective C with Cocoa helps us to load png, jpg, tiff and other image formats file using UIImage and UIImageView but UIImageView will not allow you to load SVG files. 

What are SVG images?

Scalable Vector Graphics (SVG) is a XML-based file format for two-dimensional vector graphics. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted and, if required, compressed. As XML files, SVG images can be created and edited with any text editor, but it is often more convenient to create them with drawing programs such as Inkscape.

Now lets know how we can load SVG images in our iPhone or iPad application using Cocoa Objective-C.  UIWebView allows us to load SVG images directly to our app. The code to load SVG image is given below.

NSString *path = [[NSBundle mainBundle] pathForResource:@"image" ofType:@"svg"];

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:path];

NSURLRequest *req = [NSURLRequest requestWithURL:fileURL];

[webView setScalesPageToFit:YES];

[webView loadRequest:req];

(Solved) Integrate C++ code with Objective C in XCode

 

XCode is a IDE which works only on MAC systems. XCode provides support to program in Objective-C language, C, C++, OpenGL and etc.. Objective-C codes are saved in .m format, C files in .c and C++ files in .cpp format. But when you try to integrate C++ code with Objective-C code, then XCode shows an error. This is because Objective-C code performs late binding but C++ code performs Compile time binding. So there will be mismatch with the compiler. 

Techspace provides you a solution with which you will be able to integrate C++ files with Objective-C code. When you try to include "iostream" file in C++, XCode shows an error saying "iostream" file cannot be found. The solution for this is to save ".c" or ".cpp" file in ".mm"  format. 

".mm" specifies that instead of compiling with Objective-C compiler, compile the file with default c++ compiler. Now if you come across error saying any of the import or include files not found, then change the Objective-C file which is currently saved in ".m" format to ".mm". Now clean the project and re-build and run. This should work without any errors. 

Please post your comments below if you still get errors and find difficulty in finding solution for the problem. Stay tuned for lot many solutions.

Programming on the go for Android with Android IDE

Yes. You're hearing it right. You can now develop applications for Android from your very own Android phone.

Text Editor of AIDE

AIDE is a Java integrated development environment for developing Android applications directly from your android phone. Developers can now write, compile, build and run the code directly from their phones. AIDE comes with a rich and well thought interface and adds most of the developer tools that you would use if you were running it on eclipse. AIDE has made best use of limited screen real estate to make it easy for developers to work on. AIDE provides features like error correction as you type, quick fixes, suggestions, syntax highlighting, code refactoring, project file manager, integrated logcat viewer and much more. It just takes one single click to create a sample code and start working on it. AIDE also supports .classpath files created by your Eclipse project. In lame language, you can just move the whole eclipse project to your phone without any hassle.

Integrated Logcat in IDE

AIDE doesn't just do things, it does things right. Even though compilation is a resource intensive task, AIDE works seamlessly without any lag. The text editor brings awesomeness with pinch-to-zoom and infinite undo-redo things.Even though AIDE is mainly aimed at tablets, it works fine on a smartphone. AIDE shows that the new generation smartphones are more than just fancy bird games.

It may not make sense to develop apps from scratch on a smartphone, but its compatibility with the eclipse project files bring some hope.

You can get it here on Google Play.

Move from Wordpress to Google Blogger including images

Google Blogger and Wordpress provides best way to host a blog or website of our own. There are lot of advantages and disadvantages in both but this article doesn't tell you anything about those. This article helps you to move your blog/website from Wordpress to Blogger. Without stretching this matter for a long and make you tiresome with unwanted things, will strike with the steps to move from Wordpress to Blogger.

1. First login to your Wordpress dashboard.
2. Go to Tools->Export->All->Download/Export.
3. The file which you downloaded in step 2 will be in WXR file format. Blogger takes perfect XML file format. So we have to convert the WXR file to XML file. We have nice converter over net to help us with this task.
4. Go to http://wordpress2blogger.appspot.com/ and input the downloaded WXR file as input. (Note, the WXR file should not exceed 1MB. If it exceeds, then export several WXR files by selecting the start date and end date before exporting.) Now press Convert button and wait for 10-30 seconds to process the input file and download the converted file.
5. Now login to your blogger account and go to Settings->Other->Import Blog and provide the converted file as input.

That's it. You are done with moving your posts, comments, authors and time stamps from Wordpress to Blogger but the problem here is that the imported posts will contain the images/pictures URL of the old Wordpress. So we have to host all the images to different location and change the image source URL. Techspace provides you with a unique solution to import images to your posts and the steps go as given below.

• Create an account in Dropbox.

• Now login to Dropbox account and download the installation package and install in your system.

• Now login to your Wordpress hosted site like GoDaddy, Hostgator, Dreamhost etc... and download the contents of wp-content/uploads.

• Copy the contents of downloaded file to dropbox's Public folder and wait for the contents to sync to the dropbox account/cloud.

• Now open dropbox account from web browser and open Public folder and click on any of the file and click on Copy Public Link and copy file URL which is something like this http://dl.dropbox.com/u/66540040/ (Copy only till /u/66540040 sort. Here 66540040 is your_account_number).

 

   

 

• Now open the converted file from step 4 of first tutorial(above) using notepad or word-pad or any other file editing software and now Find and Replace http://www.your-blogname.com/wp-content/uploads/ with http://dl.dropbox.com/u/your_account_number/ and then upload the edited XML file to Blogger as input.
