在objc中動態添加字符串

Question

我想從result.text動態添加字符串值，我希望以這種方式顯示它[@"17052648287",@"17052607335"]而不會丟失值。我該怎麼做？

NSMutableArray *strings = [@[@"17052648287",@"17052607335"] mutableCopy]; 

添加上編碼

- (void)captureResult:(ZXCapture *)capture result:(ZXResult *)result{ 
    if (!result) return; 

if(self.hasScannedResult == NO) 
{ 
    //Scan Result, added into array 
    NSString *scanPackage = [NSString stringWithFormat:@"%@", result.text]; 

    scanLists = [NSMutableArray new]; 
    [scanLists addObject:scanPackage]; 

    NSUserDefaults *preferences = [NSUserDefaults standardUserDefaults]; 
    NSMutableArray *strings = [[NSMutableArray alloc]init]; 
    strings = [@[result.text] mutableCopy]; 
    [preferences setObject:strings forKey:@"strings"]; 
    NSMutableArray *stringsArray = [preferences objectForKey:@"strings"]; 
    for (NSString *string in stringsArray) { 
     NSLog(@"string: %@", string); 
    }

聲明一個結果數組：你在何處獲得result.text

NSMutableArray * array = [NSMutableArray new]; 

寫下面的代碼：

NSString *scanPackage = [NSString stringWithFormat:@"%@", result.text]; // If this code is working for you 
[array addObject: scanPackage]; 
NSString *combined = [array componentsJoinedByString:@","]; 
NSLog(@"combined: %@", combined);
