Swift

I-Scrollview kanye nokusetshenziswa kwayo ku-Swift kusetshenziswe yonke indawo ekuthuthukisweni kwesicelo seselula. I-Swift, iwulimi oluqinile nolusebenzisa isikhathi olwakhiwe i-Apple, inikeza izici eziningi ezithuthukisa ukusebenzelana komsebenzisi nolwazi lomsebenzisi, enye yazo iScrollview. I-Scrollview isiza ukubonisa okuqukethwe okungaphezu kwalokho isikrini esingakubamba kuphela ngokunika amandla abasebenzisi ukuthi baskrole futhi babuke okuqukethwe. Nokho, ngezinye izikhathi ukubonakala kwebha yokuskrola ngaphakathi kwe-Scrollview kungase kuphazamise, noma onjiniyela bangase bafune ukungeza umklamo wabo wangokwezifiso webha yokuskrola.

Impela, nakhu ukubuka konke okuningiliziwe kokuthi ungashintsha kanjani usayizi we-SwiftUI Swift ku-Swift.

I-SwiftUI iwuhlaka lwe-Apple lokwakha izixhumanisi zabasebenzisi kuwo wonke amapulatifomu e-Apple ngamandla e-Swift. Kwesinye isikhathi, onjiniyela bangase bahlangabezane nesidingo sokulungisa usayizi wezingxenye ezithile ze-UI, njengeswishi. Ngokuzenzakalelayo, i-SwiftUI ayikuvumeli ukuguqula usayizi we-Switch ngokuqondile, kodwa singasebenzisa ama-workaround athile ukufeza lokhu.

Ake singene esixazululweni senkinga.

Ukudala Ukushintsha Ngokwezifiso ku-SwiftUI

Ukuze ulungise usayizi Wokushintsha ku-SwiftUI, indlela eyodwa iwukudala Ukushintsha ngokwezifiso. Lokhu kukuvumela ukuthi ukwazi ukulawula ngokuphelele ukubukeka nosayizi we-Switch.

Nasi isibonelo sekhodi edala ukushintshwa ngokwezifiso:

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 Ikhodi Yokushintsha Ngokwezifiso

Ake sihlukanise ukuthi le khodi yenzani:

• Isakhiwo se-CustomSwitch: Lokhu kuchaza ukubukwa kwethu kwe-SwiftUI ngokwezifiso. Inesibopho senani le-boolean - isimo sokushintsha.
• Isenzo senkinobho: Lokhu kuvinjwa kwekhodi ye-Swift kucacisa ukuziphatha lapho inkinobho icindezelwa. Lapha, vele uguqule isimo se-"isOn".
• Unxande: Isibonelo sesakhiwo sikanxande we-SwiftUI, esichaza izakhiwo zomumo.
• Gcwalisa Umbala: Umbala Wonxande uncike ekutheni i-“isOn” iyiqiniso noma amanga.
• Uzimele: Isilungisi sozimele lapha sisho ububanzi nobude beswishi yangokwezifiso.
• Imbondela: Isilungisi sembondela sikuvumela ukuthi wendlale okunye Ukubuka kwe-SwiftUI phezu kwaleyo ekhona - lapha, Umbuthano omhlophe osebenza njenge-switch knob.
• Okuxhunyiwe: Isilungisi se-offset sisetshenziswa lapha ukuhambisa Umbuthano kuye ngokuthi i-“isOn” iyiqiniso noma ingamanga, okunikeza inkohliso yokuthi iswishi iyashintsha.
• cornerRadius: Lokhu kusebenza ukufinyezwa emakhoneni Onxande ongaphansi.
• ukugqwayiza: Isilungisi sokugqwayiza sisebenzisa ukugqwayiza kwentwasahlobo() kuyo yonke Inkinobho - ngakho uma ushintsha, izoshintsha kahle.

Ukufaka phezulu

Ukuba nekhono lokwenza ngendlela oyifisayo usayizi we-SwiftUI Swift kungaba inzuzo lapho uhlanganisa ukusebenzelana komsebenzisi ukuze kufane nezidingo ezithile zohlelo lokusebenza. Sifunde indlela eyodwa yokufeza lokhu ngokudala Ukushintsha ngokwezifiso. Jabulela ukubhala ngekhodi!

Khumbula: I-SwiftUI ivumelana nezimo futhi ingenziwa ngezifiso. Zizwe ukhululekile ukulungisa amanani nezakhiwo kukhodi engenhla ukuze kulingane kangcono nezidingo zakho zephrojekthi nedizayini. Uma udinga ukushintsha usayizi wanoma yiziphi ezinye izingxenye ze-UI, indlela yokudala ngokwezifiso ingasetshenziswa ngendlela efanayo.

Ukuqonda iyonke itimu nokukhanga okubonakalayo kohlelo lokusebenza kuncike kakhulu ezintweni zobuhle ezizihlanganisayo; interface yomsebenzisi nolwazi lomsebenzisi. Isici esisodwa salokhu ukwenza ngezifiso imibala yangemuva yezakhi ukuze kuthuthukiswe ukukhanga kobuhle. Esimweni se-UIDatePicker noma i-UIPickerView, ukwenza ngokwezifiso umbala wangemuva kunganikeza ulwazi olungcono lomsebenzisi. Ulimi olusheshayo lunikeza izindlela ezimbalwa zokufeza lokhu. Lesi sihloko sizokuqondisa ukuthi ungakwenza kanjani lokho.

Impela. Ngezansi isibonelo sendlela engingayibhala futhi ngihlele ngayo isihloko.

I-Swift ingenye yezilimi zokuhlela ezinamandla kakhulu futhi ezinembile emhlabeni; isetshenziselwa i-macOS, iOS, watchOS, kanye nokuthuthukiswa kohlelo lokusebenza lwe-tvOS. Ngempela wulimi olukhethwa yi-Apple. Kulo mongo, sizokwethula inkinga evamile etholwe onjiniyela abaningi be-Swift, okungeza isilayidi. Sizokuqondisa ngokwakha isilayidi esilula ku-Swift futhi sibonise ukusebenza kwaso.

I-SwiftUI, uhlaka lwakamuva lwe-UI ye-Apple, ivumela abathuthukisi ukuthi baklame izinhlelo zokusebenza ngendlela echazayo, ikwenze kube lula futhi kube lula ukusebenza nazo. Iletha indlela entsha yokuklama i-UI ngezakhi zayo ezilula nezilula zolimi. Enye yezingxenye eziqondile kodwa ezibalulekile ku-SwiftUI i-TextField, inkambu yokufaka evumela abasebenzisi ukuthi bafake umbhalo ngekhibhodi. Kulesi sihloko, sizocubungula ukuthi yini eyenza i-TextField ku-SwiftUI ihluke, indlela yokwenza ngokwezifiso zayo, kanye nezinselele okungenzeka uhlangane nazo endleleni.

I-SwiftUI TextField, ngokuzenzakalelayo, iza nedizayini encane, engase inganakekeli ukunambitheka kwawo wonke umuntu. Ingase ingahambisani nayo yonke itimu yohlelo lwakho lokusebenza, noma mhlawumbe ufuna ukukunika umuzwa ohlukile ukuze usethe uhlelo lwakho lokusebenza luhluke kwezinye.

Njengolimi lokuhlela olusetshenziswa kabanzi oluklanyelwe i-iOS, i-macOS, nezinye izinhlelo zokusebenza ezimbalwa ze-Apple, i-Swift inikeza inqwaba yezici eziklanyelwe ukwenza lula ukwakhiwa kwezinhlelo zokusebenza ezigcwele izici. Isibaluli esisodwa esinjalo ukulungiswa kombala wefonti. Nakuba ubonakala ungabalulekile, umbala wefonti ungathuthukisa kakhulu ulwazi lomsebenzisi ngokuthuthukisa ukufundeka nokukhanga okubonakalayo. Nakuba umsebenzi ungase ubonakale unzima kwabaqalayo, ukuhlanganisa umbala wefonti ku-Swift kuwumsebenzi oqonde ngendlela emangalisayo onemigqa embalwa elula yekhodi.

Kulesi siqeshana, sizongena ekuhloleni okujulile kokuthi sisetshenziswa kanjani ukushintsha kombala wefonti ku-Swift.
