Custom iOS7 AlertView

v0.7

The addSubview is not available in UIAlertView in iOS7 any more. The view hierarchy for this class is private and must not be modified.

As a solution, this class creates an iOS7-style dialog which you can extend with any UIViews or buttons. The animations and the looks are copied too and no images or other resources are needed.

A demo screen

Install

As simple as adding the following files to your project:

  • CustomIOS7AlertView.h
  • CustomIOS7AlertView.m

Change notes

The initWithParentView method is now deprecated. Please use the init method instead, where you don't need to pass a parent view at all. In case the init doesn't work for you, please leave a note or open an issue here.

Quick start guide

  1. Create the UIView object changed

    CustomIOS7AlertView *alertView = [[CustomIOS7AlertView alloc] init];

  2. Add some custom content to the alert view (optional)

    UIView *customView ..;

[alertView setContainerView:customView];

  3. Display the dialog

    [alertView show];

More functions

  • Close the dialog

    [alertView close];

  • To add more buttons, pass a list of titles

    [alertView setButtonTitles:[NSMutableArray arrayWithObjects:@"Button1", @"Button2", @"Button3", nil]];

  • You can remove all buttons by passing nil

    [alertView setButtonTitles:NULL];

  • You can enable or disable the iOS7 parallax effects on the alert view

    [alertView setUseMotionEffects:TRUE];

  • Handle button clicks with a custom delegate

    First, set the delegate:

    [alertView setDelegate:self];

    Then add the delegate methods:

    - (void)customIOS7dialogButtonTouchUpInside: (CustomIOS7AlertView *)alertView clickedButtonAtIndex: (NSInteger)buttonIndex
{
    NSLog(@"Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]);
}

  • Handle button clicks with a code block

    [alertView setOnButtonTouchUpInside:^(CustomIOS7AlertView *alertView, int buttonIndex) {
    NSLog(@"Block: Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]);
    [alertView close];
}];

    You can also disable all other delegates by:

[alertView setDelegate:self]; ```

Todos

This is a really quick implementation, and there are a few things missing:

  • Adding more buttons: they don't exactly match the look with that of on iOS7

  • Keyboard support: the dialog might be mispositioned in some cases

Special thanks to

  • @tamasdancsi for his support with the initial code
  • @dingosky for his work on the parallax effects code
  • @raspu for his work on the protocol delegates, iOS6 support and onButtonClick blocks
  • @sbandol for his idea on adding the AlertView as the top most view in the hierarchy
  • @scorpiozj for his work on the rotation code
  • @kwent for adding performance optimisations
