ProgressView/ProgressBar Xcode

Question

我想知道如何設置進度條等於xcode中的最大用戶輸入。

@property (weak, nonatomic) IBOutlet UIProgressView *progressBar; 


- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
    _inputAmount.keyboardType = UIKeyboardTypeDecimalPad; 
    self.amount = [NSMutableArray new]; 
    [self.amount addObject:@"Total Amount of Push-Ups:"]; 
    [self.myList setDataSource:self]; 

    _inputAmount = UIProgressViewStyleBar; 
} 

這只是我的代碼snipet，該inputamount =進度條就是我想做的事，但我真的不知道該怎麼做。我希望最大的輸入量等於progressviewbar。所以我將不得不比較所有添加到數組中的＃。有任何想法嗎？謝謝！
