Ios 在 Swift 中追加字符串

发布于06月12日

我是IOS的新手.我目前正在使用Objective-C和SWIFT学习IOS.

要在Objective-C中附加字符串，我使用以下代码:

 NSString *string1 = @"This is";
 NSString *string2 = @"Swift Language";
 NSString *appendString=[NSString stringWithFormat:@"%@ %@",string1,string2];
 NSLog(@"APPEND STRING:%@",appendString);

有没有人请给我带路.

推荐答案

很简单:

For ObjC:个

     NSString *string1 = @"This is";
     NSString *string2 = @"Swift Language";

ForSwift:个

    let string1 = "This is"
    let string2 = "Swift Language"

For ObjC AppendString:

     NSString *appendString=[NSString stringWithFormat:@"%@ %@",string1,string2];

For Swift AppendString:个

    var appendString1 = "\(string1) \(string2)"
    var appendString2 = string1+string2

Result:个

    print("APPEND STRING 1:\(appendString1)")
    print("APPEND STRING 2:\(appendString2)")

Complete Code In Swift:个

    let string1 = "This is"
    let string2 = "Swift Language"
    var appendString = "\(string1) \(string2)"
    var appendString1 = string1+string2
    print("APPEND STRING1:\(appendString1)")
    print("APPEND STRING2:\(appendString2)")
