Swift

I-Scrollview kunye nokusetyenziswa kwayo kwi-Swift isetyenziswe kwiindawo zonke kuPhuhliso lweSicelo seMobile. I-Swift, ilulwimi oluluqilima nolusebenzayo oluphuhliswe nguApple, lubonelela ngeempawu ezininzi zokuphucula ujongano lomsebenzisi kunye namava omsebenzisi, enye yazo yiScrollview. I-Scrollview iququzelela ukubonisa umxholo ngaphezu koko isikrini sinokubamba kuphela ngokuvumela abasebenzisi ukuskrola nokujonga umxholo. Nangona kunjalo, ngamanye amaxesha ukubonakala kwebar yokuskrola ngaphakathi kweScrollview kunokuphazamisa kancinci, okanye abaphuhlisi banokufuna ukongeza uyilo lwebar yokuskrola yesiko.

Ngokuqinisekileyo, nantsi inkcazo eneenkcukacha malunga nendlela onokutshintsha ngayo ubungakanani beSwiftUI Tshintshela kwiSwift.

I-SwiftUI sisikhokelo se-Apple sokwakha ujongano lomsebenzisi kuwo onke amaqonga e-Apple ngamandla e-Swift. Ngamanye amaxesha, abaphuhlisi banokudibana nesidingo sokulungelelanisa ubungakanani bezinto ezithile ze-UI, njengokutshintsha. Ngokungagqibekanga, i-SwiftUI ayikuvumeli ukutshintsha ubungakanani boTshintsho ngokuthe ngqo, kodwa sinokusebenzisa ezinye iindlela zokusebenza ukuphumeza oku.

Masingene kwisisombululo sengxaki.

Ukwenza uTshintsho lwesiNtu kwi-SwiftUI

Ukunyenyisa ubungakanani boTshintsho kwi-SwiftUI, enye indlela kukwenza uTshintsho lwesiko. Oku kukuvumela ukuba ube nolawulo olupheleleyo kwimbonakalo kunye nobukhulu beTshintsho.

Nanku umzekelo wekhowudi eyenza utshintsho oluqhelekileyo:

struct CustomSwitch: View {
    @Binding var isOn: Bool
    var body: some View {
        Button(action: {
            self.isOn.toggle()
        }) {
            Rectangle()
                .fill(self.isOn ? Color.green : Color.gray)
                .frame(width: 50, height: 30)
                .overlay(Circle()
                            .fill(Color.white)
                            .offset(x: self.isOn ? 10 : -10),
                         alignment: self.isOn ? .trailing : .leading)
                .cornerRadius(15)
                .animation(.spring())
        }
    }
}

Ukuqonda iKhowudi yokuTshintsha ngokweSiko

Masicazulule into eyenziwa yile khowudi:

• Ubume beCustomSwitch: Oku kuchaza umbono wethu weSwiftUI yesiko. Inokubophelela kwixabiso le-boolean - imeko yokutshintsha.
• Iqhosha lentshukumo: Le block yekhowudi ye-Swift ikhankanya ukuziphatha xa iqhosha licofa. Apha, tshintsha ngokulula imo ye "isOn".
• Uxande: Umzekelo weSwiftUI's Rectangle structure, echaza iimpawu zemilo.
• Gcwalisa Umbala: Umbala weRectangle uxhomekeke ekubeni "isOn" yinyani okanye bubuxoki.
• Isakhelo: Isilungisi sesakhelo apha sichaza ububanzi kunye nobude bokutshintsha kwesiko.
• Isangqa: Isilungisi sokwaleka sikuvumela ukuba umaleko enye iSwiftUI Jonga ngaphezulu kwesele ikhona - apha, isangqa esimhlophe esisebenza njengeqhosha lokutshintsha.
• Ukuseta: Isilungisi sokulinganisa sisetyenziswa apha ukuhambisa iSangqa ngokuxhomekeke ekubeni "isOn" yinyani okanye ayiyonyani, inika inkohliso yokuba iswitshi iyajika.
• cornerRadius: Oku kusebenza ukusondeza kwiikona zoxande olungaphantsi.
• oopopayi: Isilungisi soopopayi sisebenzisa upopayi wasentwasahlobo () kulo lonke iQhosha - ke xa uswitsha, lizakuguquguquka kakuhle.

Ukuqhawula phezulu

Ukuba namandla okwenza ubungakanani beSwiftUI Tshintshela inokuba luncedo xa ulungelelanisa ujongano lomsebenzisi ukuze utshatise iimfuno ezithile zesicelo. Sifunde indlela enye yokuphumeza oku ngokwenza uTshintsho lwesiko. Ikhowudi yolonwabo!

khumbula: I-SwiftUI ibhetyebhetye kwaye iyakwazi ukwenziwa. Zive ukhululekile ukunyenyisa amaxabiso kunye neepropathi kwikhowudi engentla ukuze ulungele kangcono iprojekthi yakho kunye neemfuno zoyilo. Ukuba ufuna ukutshintsha ubungakanani bawo nawaphi na amanye amacandelo e-UI, indlela yokwenza isiko ingasetyenziswa ngendlela efanayo.

Ukuqonda umxholo opheleleyo kunye nesibheno esibonakalayo sesicelo kuxhomekeke ubukhulu becala kwizinto zobuhle ezibandakanya; ujongano lomsebenzisi kunye namava omsebenzisi. Umba omnye wale nto kukwenza imibala yangasemva yeempawu zokuphucula umtsalane wobuhle. Kumzekelo we-UIDatePicker okanye i-UIPickerView, ukwenza ngokwezifiso umbala ongasemva kunokubonelela ngamava angcono omsebenzisi. Ulwimi olukhawulezayo lubonelela ngeendlela ezininzi zokuphumeza oku. Eli nqaku liza kukukhokela kwindlela yokwenza oko.

Ngokuqinisekileyo. Apha ngezantsi kukho umzekelo wendlela endiya kubhala ngayo kwaye ndicwangcise inqaku.

I-Swift yenye yezona lwimi zinamandla kwaye zinomdla kwihlabathi; isetyenziselwa iMacOS, iOS, watchOS, kunye nophuhliso lweapp yetvOS. Ngokwenene lulwimi olukhethwa nguApple. Kulo mongo, siza kwazisa ingxaki eqhelekileyo efunyenwe ngabaphuhlisi abaninzi be-Swift, eyongeza isilayidi. Siza kukukhokela ngokwenza isilayidi esilula kwi-Swift kwaye sibonise ukusebenza kwayo.

I-SwiftUI, isakhelo se-UI yamva nje ye-Apple, ivumela abaphuhlisi ukuba bayile ii-apps ngendlela echazayo, iyenza ibe lula kwaye ibe lula ukusebenza nayo. Izisa indlela entsha yoyilo lwe-UI kunye nolwakhiwo lwayo olulula nolulula lolwimi. Enye yezinto ezithe ngqo kodwa ezibalulekileyo kwi-SwiftUI yi-TextField, indawo yokufaka evumela abasebenzisi ukuba bafake umbhalo ngekhibhodi. Kweli nqaku, siza kuphonononga ukuba yintoni eyenza i-TextField kwi-SwiftUI ibe yodwa, indlela yokwenza isitayile ngokwezifiso, kunye nemiceli mngeni onokuthi udibane nayo endleleni.

I-SwiftUI TextField, ngokungagqibekanga, iza noyilo oluncinci, olunokuthi lungakhathaleli incasa yomntu wonke. Isenokungahambelani nomxholo opheleleyo wosetyenziso lwakho, okanye mhlawumbi ufuna ukuyinika imvakalelo eyodwa ukuseta iapp yakho yahluke kwezinye.

Njengolwimi olusetyenziswa ngokubanzi lwenkqubo eyenzelwe ngokukodwa i-iOS, i-macOS, kunye nezinye iinkqubo zokusebenza ze-Apple, i-Swift ibonelela ngobuninzi beempawu eziyilelwe ukuququzelela ukuyilwa kwezicelo ezipakishweyo. Olunye olu phawu luhlengahlengiso lombala wefonti. Nangona ubonakala ungabalulekanga, umbala wefonti unokuphucula kakhulu amava omsebenzisi ngokuphucula ukufundeka kunye nokubukeka okubonakalayo. Nangona umsebenzi unokubonakala unzima kwii-novices, ukulungisa umbala wefonti kwi-Swift ngumsebenzi ocacileyo ocacileyo onemigca embalwa yekhowudi.

Kwesi siqwenga, siza kungena kuphononongo olunzulu lwendlela yokuphumeza utshintsho lombala wefonti kwi-Swift.

INkqubo eSwift kunye neNgcaciso yeSangqa - Uhlalutyo olunzulu

Inkqubo eSwift, umdlali owaziwayo kwibala lophuhliso losetyenziso, waziwa ngeempawu ezikhawulezayo, zale mihla, ezikhuselekileyo kunye nezokusebenzisana. Enye yeendima ezibalulekileyo ze-Swift kucwangciso kubuchule bayo bokwenza lula imisebenzi entsonkothileyo efana nokukhohlisa iimilo, ngokukodwa izangqa. Kolu phando, siza kugocagoca kwisisombululo esibanzi sokujongana nezangqa e-Swift, siphonononge inkcazo yekhowudi kwinkqubo yenyathelo nenyathelo, kwaye siqaqambise amathala eencwadi okanye imisebenzi ebandakanyekayo kule nkqubo okanye ukufana kwayo.
