如何獲取文本標籤中的數組值而不是密鑰

Question

我有一個文本標籤，當我按下按鈕時會發生變化，標籤確實會隨着使用數組而改變，而不是數組的值我得到數組的鍵。

我應該怎麼做才能獲得這些值？

這是代碼：

NSString*path = [[NSBundle mainBundle]pathForResource:@"words" ofType:@"plist"]; 
    words = [[NSMutableArray alloc]initWithContentsOfFile:path]; 
    NSString*generateRandomLabel =[NSString stringWithFormat:@"%d", arc4random_uniform([ words count])]; 
    [self.randomLabel setText:generateRandomLabel]; 

Answer 1

NSString*path = [[NSBundle mainBundle]pathForResource:@"words" ofType:@"plist"]; 
words = [[NSMutableArray alloc]initWithContentsOfFile:path]; 
NSString*generateRandomLabel = nil; 
if ([words count] >0) 
    generateRandomLabel = [NSString stringWithFormat:@"%@", [words objectAtIndex:arc4random_uniform([ words count]-1)]]; // To make sure object is not out of bounds of array add -1 
else 
    generateRandomLabel = @"No values in array"; 
[self.randomLabel setText:generateRandomLabel];
