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

This can be viewed in "preview" option in the assis...

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 t...
