在ios中添加一个格式为数字和声音的字符串

Question

如何以数字$ sound的格式返回附加的字符串，然后当它返回时，将字符串分解为两个部分，如objective-c中的（数字和声音文件名）

Answer 1

整数版：

int number = 10;    
NSString *sound = @"sound";
NSString *combinedString =
  [sound stringByAppendingString:
     [NSString stringWithFormat:@"%d$%@",number,sound]];

字符串版本：

NSString *number = @"10";    
NSString *sound = @"sound";    
NSString *combinedString = 
  [sound stringByAppendingString:
    [NSString stringWithFormat:@"%@$%@",number,sound]];

输出：10 $声音

NSArray *combinedObjects  = [combinedString componentsSeparatedByString:@"$"];    
NSString *mynumber=[combinedObjects objectAtIndex:0];//10    
NSString *mysound= [combinedObjects objectAtIndex:1];//sound

Answer 2

将NSString与$

分开

NSArray* separatedString = [yourString componentsSeparatedByString:@"$"];
