Izicelo Uphuhliso for iOS: ukuqala phi?

Suku ngalunye kwandisa inani labantu abafuna ukufunda indlela yokwenza le nkqubo. Emva ngokuqokelela ulwazi kwi network eza kubo ingcamango yokuba kwezithembiso kakhulu uphuhliso izicelo iOS - Apple kaThixo operating system. Enyanisweni, iphupha - eli namnye, kunye nokufakwa kweenkqubo - omnye. Yenza isicelo sakho akukho lula. Kodwa hayi fantastically nzima. Yintoni ekufuneka uyenze?

ulwimi lokuprograma

Ukubhala inkqubo iqonga elithile, kufuneka usebenzise ulwimi oluthile lokwakha. izicelo Ukuphuhlisa for iOS and Android zahluke. Ukuba iqonga ukusuka "Google" umele ukhethe ulwimi Java; ngokuba ukhetho iOS phakathi Objective-C kunye Swift. Kangangexesha elide ukuze kukhule iOS iqonga kokuba wenziwe kuphela koncedo Objective-C ulwimi lokuprograma. Nangona ukuba iminyaka emininzi, oko kusenzeka kwaye isetyenziswa yi inani elikhulu developers. Kodwa ezingentle - yinto yokuvinjwa kokungena.

Ekubeni mthombo uphambili ngeniso na Apple kwingqwebo yayo isicelo, ngaba abasebenzi abanomdla izixhobo luncedo ngakumbi umdla. Ngenxa yesi sizathu, iinkomfa rhoqo ngababhekisi opohambili, esixelela malunga neenguqu kwiinkqubo zokusebenza. Ngo-2014, ababhekisi phambili abonisa ulwimi olutsha lokuprograma Swift, ephuhlisa izicelo iOS. Swift kulula ukufunda, kuba uye ngesivakalisi elula kakhulu kwaye mazitayitshwe ngamandla. Kuba abo bafuna ukufunda ukwakha izicelo iOS umnikazi ulwimi ingena kakuhle kakhulu.

Yintoni efunekayo ukuze uqalise

Ukongeza ulwazi olusisiseko lwenkqubo, kufuneka ube nalemiba ilandelayo:

• yokubhalela computer kunye OSX zokusebenza nenkqubo ebhodini;
• bume yophuhliso Xcode, into simahla.

Le iseti yenza izicelo ukuze ibaleke kuyi ekhethekileyo ngqo kwi computer. Kodwa kufuneka akhumbule ukuba kwixesha elizayo kusenokufuneka ahlawule $ 99 ukubhalisa konyaka ukufumana developers program. Emva kokuba intlawulo ziya kuba nako uku:

• eyenzelwe ukuba usebenzise udweliso lwenkqubo ayikho lo mshini kwaye kwizixhobo ezizizo;
• beka app evenkileni App Store;
• download inguqulelo entsha ye bume yophuhliso kunye iOS.

Xa iinguqulelo ezintsha ze Xcode kwakukho into efana 'ibhokisi yesanti ", ebizwa zebala. Apha umyili Ungabona ulwimi olutsha lokwakha.

Abantu abaninzi bafuna ukuqalisa ukubhala iinkqubo, kodwa ndicinga ukuba kunzima kakhulu. Kakade ke, ukuze abe umsebenzi, kufuneka ube eninzi ulwazi kunye namava amaninzi emva kwabo. Kodwa ukuze ukwenza isicelo encinane, akukho mfuneko yokuba ibe yobungcali.

Indlela ukuqala ekuphuhliseni izicelo iOS and Android? Ukufunda kwenzeka practice. Ngoko ke, kuyimfuneko ukuba siqale. imibono abaninzi - akusoloko elungileyo. Ngapha koko, ukuba umntu ayifunde layigqiba iincwadi ezilishumi lwenkqubo, computer, yena ngeke. Kufuneka senze.

yokudlala

Oku "ibhokisi yesanti" - oku yimeko-bume enye enkulu ukufunda ulwimi lokuprograma. Njengoko kubonakala? Umsebenzisi ongena umgca lwekhowudi kwaye ubone kwaoko ngenxa ngokubulawa. Xa kucaca ukuba isiqwenga ebhaliweyo isebenza ngendlela ekumele, oko nje kutshintshelwa le projekthi. Ngoncedo i 'ibhokisi yesanti "bebenoyilungisa imisebenzi efana nale:

• uphuhliso lwesivakalisi ulwimi lokuprograma;
• nokuphucula izakhono zokuhlela ngoncedo amalinge kunye API entsha;
• ukuphunyezwa izibalo ezilula yokalo emileyo;
• uphuhliso algorithm entsha ekujongile yakhe yonke.

Ukwakha izicelo iOS: ukuqalisa apho

Ithiyori - kuba ngokuqinisekileyo elungileyo, kodwa, njengoko kuchaziwe ngaphambili, ithatha practice. Ukuze simazi kakuhle i "ibhokisi yesanti", ufuna bume yophuhliso Xcode. Emva kokuqalisa kokuba umsebenzisi ungabona window, apho uceba ukwenza iprojekthi entsha okanye uqale zebala. Ndidinga indawo yesibini. Ngoku kufuneka ukuza igama uze ugcine i 'ibhokisi yesanti "kuyo nayiphi na indawo elula kwi khompyutha yakho. Hi ndlela leyi, uphuhliso izicelo iOS to Windows kwakhona kunokwenzeka, kodwa ke kufuneka ukuba ukusombulula iingxaki ezininzi. Le ukufakelwa nkqubo pirated yokusebenza, kunye hlela iifayile ebalulekileyo, kunye bugs ezininzi nezinobuzaza.

Xa sele basindiswayo iza kuphehlelelwa i zebala enye, nto leyo efunekayo.

Xa uqala kuqala, akukho nto umdla. Kodwa kuyimfuneko ukuba ufake ikhowudi yakho ngathi ngembonakalo iza kutshintsha ngoko nangoko.

Kuba Okokuqala, unga zama ukubhala oku kulandelayo:

var z = 3

ngokuba var y = 0; y <10; ++ y {

z + = z * y

}

z

println ( "japan: (z)")

Emva koku 'ibhokisi yesanti "kuzakutshintsha ukubonakala kwayo. Kumhlathi osekunene (lenjongo iziphumo) ibonisa amanani kumgca ngamnye, ezo zifunyenwe emva kubulawa. Kwakhona kumhlathi osekunene, ungakhetha ukubonisa ixesha bar, nto leyo evumela ukuba ukulandelela utshintsho ekuhambeni kwexesha eli binzana ekhethiweyo. Kwakhona ibonisa imveliso console kwisicatshulwa eyayiza kuba imveliso evela kwinkqubo.

ikhodi amazwana

izicelo Uphuhliso for iOS, kwakunye nezinye amaqonga, hayi ngaphandle izimvo, eyimfuneko ukuqinisekisa ukuba umphuhlisi kwaba lula ukuyisebenzisa kwi khowudi. Izimvo - le layini awahoywa ngexesha inkqubo nokusebenza. Iiplastiki zombini single-line kunye emininzi.

eziguquguqukayo

Ngoko ke, izicelo zibhalwa ngolwimi lokuprograma. Basekele wengxenye bume ulwimi. izicelo Ukuphuhlisa for iOS and Android kunokwenzeka ngaphandle kokusebenzisa variables hayi. Nanjengoko igama layo lixela, oko isikhongozelo, leyo iqulathe ixabiso elitshintshayo. Ngamnye variable kufuneka igama elikhethekileyo kwaye anokuqulatha zombini amaxabiso yamanani kunye netekisi. Ulwimi lokuprograma variables Swift ichazwa usebenzisa igama var and let. Kwimeko yesibini, variable alunako ukutshintshwa kwaye kufuneka ukuqaliswa kwi kwisibhengezo. Kwimeko yokuqala, variable into ukuqaliswa ngokukhawuleza ngaphambi kokuba uyisebenzise.

Nganye variable has uhlobo ethile. Oku kuba sistring, lencopho amanani indawo amaxabiso (iqhezu) boolean (lokwenyaniso nolobuxoki).

Imveliso kweziphumo

Isiphumo lwenkqubo uboniswa ku console. Yintoni na? Le nto inika intsebenziswano umsebenzisi kunye nekhompyutha. Ngoko ke, lo imveliso we console wayedla ngokuba esweni kunye igalelo console - keyboard. Ke intsingiselo yamagama omncinane itshintshile. Ngoko-wabiza window ethambileyo ukuba igalelo lomyalelo kunye nemveliso. Ukwakha izicelo iOS rhoqo kufuna ukurhoxiswa naziphi data. Ukuze wenze oku ku Swift kulwimi olunikiweyo umyalelo woshicilelo kunye println. Awafani zokuqala ukusuka yesibini eqala ngokuzenzekelayo umgca omtsha.

imisebenzi

Ingcinga ilandelayo ezisisiseko senkqubo - imisebenzi. It is a ulandelelwano oluthile lwezinto enze umsebenzi othile. umsebenzi ngalinye singathatha nasiphi na ixabiso, ndibuyele isiphumo. Ukuze usebenzise le sakhiwo, kufuneka kuqala makatsho kunye func elingundoqo. Emva iqulathe igama kunye yegama. Ukuba ixabiso kufuneka ibuyiselwe, emva kwizibiyeli abonisa uhlobo yayo. Ukuba ixabiso ukubuya ayikho, uhlobo alukhankanywanga, okanye ukubonisa "engenanto 'uhlobo - ungalanjathiswa. Kwindawo yegama kokuxabisekileyo ukuba itheko. Ukufowunela umsebenzi a ukubonisa igama nemilinganiselo ye iingxoxo.

Ungenza igama parameter kwi umnxeba umsebenzi saboniswa ngokuyimfuneko. Ukuza kuthi ga ngoku, oku yabakho uphawu 'grid ".

Ngoko unako ukubhala nayiphi na imisebenzi luncedo ukuba unako, umzekelo, ukubala exchange, ukuguqula enye iyunithi yomlinganiselo ukuya kwenye. Ngalo lonke ixesha kukho imfuneko yokusebenzisa kubo, nje ngokwaneleyo ukubiza le misebenzi, endaweni ukubhala ikhowudi ukusuka ekuqaleni.

Yintoni ngoku?

Ngoko ke, njengoko kubonakala ngentla apha, uphuhliso izicelo iOS ngezandla zabo kakuhle phezu imikhosi yayo nganye. Eyona nto ibalulekileyo - ukufunda iziseko ulwimi lokuprograma, ukuze siqhelane bume yophuhliso kunye ixesha elininzi lokuziqhelanisa yaye ngokufuthi. Loo nto inceda ukwenza inkqubela ebonakalayo. Kodwa njengoko kuchaziwe apha - nto nje kwasekuqaleni. Ukongeza kwihlabathi senkqubo iya kuba kakhulu umdla nentsonkothileyo, ibangel 'umdla. Kuya kusoloko ugcine ingqondo yakho elibukhali, ukuze udale into entsha nephilayo elungileyo. Ngapha koko, oomatshini Apple xa zisetyenziswa ehlabathini lonke. Ngako oko, isicelo sakho siya kukwazi ukuphonononga izigidi zabantu.
