Is it possible to do operadores ternarios in swift ?
I have this type of code that I repeat many times, and I wanted to know if I can simplify it using operadores ternarios . condicion ? resultadoTrue : resultadoFalse
if fechaHasta != "" {
labelFecha.text = fechaHasta
}
Without knowing much about swift, I think what you need is this:
question ? answer1 : answer2
Example:
let contentHeight = 40
let hasHeader = true
let rowHeight = contentHeight + (hasHeader ? 50 : 20)
Instead of:
let contentHeight = 40
let hasHeader = true
let rowHeight: Int
if hasHeader {
rowHeight = contentHeight + 50
} else {
rowHeight = contentHeight + 20
}
Yes, in fact, it is equal to many languages that also use them (PHP for example). For your example it would be:
print(fechaHasta != "" ? labelFecha.text = fechaHasta : "lo que quieras poner si es falso")
I've put the function print so you can see it in the console but you could match it without problems to a variable.
Claro is easy
var fecha = ""
fecha = fecha == "" ? labelFecha.text = "no hay fecha" : labelFecha.text = fechaHasta
Compare fecha equals empty string, if true labelFecha.text say "no date", : mean "otherwise" labelFecha.text equals variable fechaHasta .
