iphone - Using UIProgressView as a Progress indicator for goals

Question

I've tried figuring this out on my own, and am completely clueless as to how to accomplish it. Essentially what I'm trying to do is this:

The Overall Goal: Use the UIProgressView as a "different type" of indicator than what it's meant for.
Details: When a user 'completes' a 'goal' (by pressing a UIButton named "complete" in a separate UIViewController, let's call this one "View Controller 1") I'd like it to update a UIProgressView in a second UIViewController (call this one "View Controller 2"). There are several UIProgressViews in View Controller 2, each representing the # of goals in a category 'completed'. So I'd like to have a void method in View Controller 2 like this:

 (void)progressMade:(NSString *)category
{
   categoryOneProgressView.progress += 1/8 ;
   //this would be called from View Controller 1, after the "complete" button was pressed.
}

Thank you in advance for your help.

Answer 1

您可以做的是在 VIEW CONTROLLER 1 中触摸按钮，您可以将已完成目标的值存储在特定类别中。视图控制器 1 的示例代码：

-(void)methodTriggeredOnCompleted:(NSString *)category
{
    //Do you calculation for progress of a category 

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    [defaults setValue:saveProgressValue forKey:category];
    [defaults synchronize];
}

现在在 View Controller 2 中，您应该在 ViewDidLoad 方法或 ViewWillAppear 方法中获取存储在 NSUserDefaults 中的值并在进度条值中更新它

-(void)viewDidLoad
{
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    int val = [defaults valueForKey:category];
    categoryOneProgressBar.progress = val;
}
