如何在Swift连接字符串?
在Objective-C中
NSString *string = @"Swift";
NSString *resultStr = [string stringByAppendingString:@" is a new Programming Language"];
or
NSString *resultStr=[NSString stringWithFormat:@"%@ is a new Programming Language",string];
但我想用swift语言来写。
当前回答
var language = "Swift"
var resultStr = "\(language) is a new programming language"
其他回答
来打印组合字符串
Println("\(string1)\(string2)")
或String3存储2个字符串组合的输出
let strin3 = "\(string1)\(string2)"
var language = "Swift"
var resultStr = "\(language) is a new programming language"
斯威夫特5:
数组的字符串变成一个单一的字符串
let array = ["Ramana","Meharshi","Awareness","Oneness","Enlightnment","Nothing"]
let joined = array.joined(separator: ",")
它被称为字符串插值。 它是用常量，变量，字面量和表达式创建新字符串的方法。 例子:
let price = 3
let staringValue = "The price of \(price) mangoes is equal to \(price*price) "
也
let string1 = "anil"
let string2 = "gupta"
let fullName = string1 + string2 // fullName is equal to "anilgupta"
or
let fullName = "\(string1)\(string2)" // fullName is equal to "anilgupta"
它也意味着串联字符串值。
希望这对你有所帮助。
你也可以在Swift中使用stringByAppendingFormat。
var finalString : NSString = NSString(string: "Hello")
finalString = finalString.stringByAppendingFormat("%@", " World")
print(finalString) //Output:- Hello World
finalString = finalString.stringByAppendingFormat("%@", " Of People")
print(finalString) //Output:- Hello World Of People
