Hello Dev mates…
\nHope you are enjoying your work in\u00a0winters; (:<\/p>\n
Few days back I was working on a project where I needed to compress some files to create a zip archive; Although my\u00a0teammate\u00a0has done much of the work, I just refined some business logic and finalized the code to complete this feature; So lets start and see how we achieved this;<\/p>\n
1. Setup your project<\/strong><\/p>\n [code language=”objc” wraplines=”false”] \/\/in .m file 2. Create a zip file in any directory under\/Document;<\/strong><\/p>\n [code language=”objc” wraplines=”false”] 3. Decompress a zip archive;<\/strong><\/p>\n [code language=”objc” wraplines=”false”] Thats all; You can use this code as it is into your project; Leave a comment if you find yourself in any trouble;<\/p>\n Happy coding, and happy winters;<\/p>\n Hello Dev mates… Hope you are enjoying your work in\u00a0winters; (: Few days back I was working on a project where I needed to compress some files to create a zip archive; Although my\u00a0teammate\u00a0has done much of the work, I just refined some business logic and finalized the code to…<\/p>\n","protected":false},"author":1,"featured_media":4549,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[],"class_list":["post-3553","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ios"],"_links":{"self":[{"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/posts\/3553","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/comments?post=3553"}],"version-history":[{"count":1,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/posts\/3553\/revisions"}],"predecessor-version":[{"id":4550,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/posts\/3553\/revisions\/4550"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/media\/4549"}],"wp:attachment":[{"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/media?parent=3553"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/categories?post=3553"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aasimnaseem.com\/blog\/wp-json\/wp\/v2\/tags?post=3553"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
