Custom view which looks like UIAlertView - ios

Question

I need something what looks like UIAlertView (same background transparent and not full screen), blocks other UI parts and has some custom content.
This custom content are: two check-boxes with labels and two buttons YES/NO at the bottom.
Sub-classing or customizing UIAlertView doesn't looks useful (see this answer) and it is dangerous (code can be rejected by Apple). I was thinking to create own custom UIView (possible with UIViewController), but I have no idea how to make it look and feel like UIAlertView. I mean I'd like to make it that it changes its appearance dependent on iOS version (iOS7).
update:
I can abandon os version dependency, it would be nice to have, but this is additional feature.
The main question is: is there a good way to make such view which will look and feel like UIAlertView without large amount of work? Customizing UIAlertView directly looks complicated and dangerous.

I created my own custom view to look like iOS UIAlertView 7. With that technique you can create a custom alert for both iOS 6 and iOS 7.
For that, I created a UIView in my xib file of my UIViewController :
I added some #property for this view :
// Custom iOS 7 Alert View
#property (nonatomic, weak) IBOutlet UIView *supportViewPopup; // My UIView
#property (nonatomic, weak) IBOutlet UIView *supportViewPopupBackground; // The grey view
#property (nonatomic, weak) IBOutlet UIView *supportViewPopupAction; // The white view with outlets
// Property for customize the UI of this alert (you can add other labels, buttons, tableview, etc.
#property (nonatomic, weak) IBOutlet UIButton *buttonOK;
#property (nonatomic, weak) IBOutlet UIButton *buttonCancel;
#property (nonatomic, weak) IBOutlet UILabel *labelDescription;
On my viewDidLoad :
- (void)viewDidLoad
{
[super viewDidLoad];
// Support View
self.supportViewPopupAction.layer.cornerRadius = 5.0f;
self.supportViewPopupAction.layer.masksToBounds = YES;
// Add Support View
[self.view addSubview:self.supportViewPopup];
// Center Support view
self.supportViewPopup.center = self.view.center;
// Alpha
self.supportViewPopup.alpha = 0.0f;
self.supportViewPopupBackground.alpha = 0.0f;
self.supportViewPopupAction.alpha = 0.0f;
}
Action to display Popup :
- (IBAction)displayPopup
{
// Support View
self.supportViewPopup.alpha = 1.0f;
self.supportViewPopupBackground.alpha = 0.5f;
// Animation
[UIView animateWithDuration:0.5f
animations:^{
self.supportViewPopupAction.alpha = 1.0f;
}];
}
Action to dismiss Popup :
- (IBAction)dismissModal
{
// Animation
[UIView animateWithDuration:0.5f
animations:^{
self.supportViewPopup.alpha = 0.0f;
self.supportViewPopupBackground.alpha = 0.0f;
self.supportViewPopupAction.alpha = 0.0f;
}];
}
So, with that you can configure your supportViewPopupAction like you want with buttons, table view, labels, collection view, etc...
I spent time to write this example of alert view. I hope this will help you !

Custom views can be passed to PXAlertView: https://github.com/alexanderjarvis/PXAlertView

Answer 3

Some components as UIButtons and UITextFields are going to look different depending on the version, so that's going to be fine, the problem I see is going to be in the view that contains then.
My suggestion is to detect the version where the app is running and then draw the alert view based on that, or just create a custom design that will fit both.

Creat view depending on the iOS versions!
NSString *version = [[UIDevice currentDevice] systemVersion];
int major = [version intValue];
if (major < 7)
//alert for the iOS 6
else
//alert for the iOS 7
