我如何在Swift连接字符串?

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"];

NSString *resultStr=[NSString stringWithFormat:@"%@ is a new Programming Language",string];

但我想用swift语言来写。

当前回答

let the_string = "Swift"
let resultString = "\(the_string) is a new Programming Language"

其他回答

非常简单:

let StringA = "Hello"
let StringB = "World"
let ResultString = "\(StringA)\(StringB)"
println("Concatenated result = \(ResultString)")

\ this被用来将一个字符串附加到另一个字符串。

var first = "Hi" 
var combineStr = "\(first) Start develop app for swift"

你也可以试试这个:- +关键字。

 var first = "Hi" 
 var combineStr = "+(first) Start develop app for swift"

试试这段代码。

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: ",")

你可以使用附加API来实现它。这将返回一个通过将给定字符串追加到接收器而生成的新字符串。

API详情:此处

Use:

var text = "Hello"
text = text.appending(" Namaste")

结果:

Hello
Hello Namaste

你现在可以在Swift中使用stringByAppendingString。

var string = "Swift"
var resultString = string.stringByAppendingString(" is new Programming Language")
