我是iOS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);
有人请指导我。
非常简单:
对于ObjC:
NSString *string1 = @"This is"; NSString *string2 = @"Swift Language";
ForSwift:
let string1 = "This is" let string2 = "Swift Language"
对于ObjC AppendString:
NSString *appendString=[NSString stringWithFormat:@"%@ %@",string1,string2];
对于Swift AppendString:
var appendString1 = "\(string1) \(string2)" var appendString2 = string1+string2
结果:
print("APPEND STRING 1:\(appendString1)") print("APPEND STRING 2:\(appendString2)")
在Swift中完成代码:
let string1 = "This is" let string2 = "Swift Language" var appendString = "\(string1) \(string2)" var appendString1 = string1+string2 print("APPEND STRING1:\(appendString1)") print("APPEND STRING2:\(appendString2)")
