ProgressView / ProgressBar Xcode

Question

我想知道如何将进度条设置为等于xcode中的最大用户输入。

@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;
}

这只是我的代码的一小部分，inputamount =进度条是我想要做的，但我不确定如何做到这一点。我希望最大输入量也等于进度视图。所以我必须比较添加到数组中的所有#s。有任何想法吗？谢谢！
