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。

这也会起作用:
var string = "swift"
var resultStr = string + " is a new Programming Language"

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
非常简单:
let StringA = "Hello"
let StringB = "World"
let ResultString = "\(StringA)\(StringB)"
println("Concatenated result = \(ResultString)")
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)"
这也会起作用:
var string = "swift"
var resultStr = string + " is a new Programming Language"
