Custom iOS AlertView

v0.9.5

support for iOS7+

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

As a solution, this class creates an iOS-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.

Install

As simple as adding the following files to your project:

• CustomIOSAlertView.h
• CustomIOSAlertView.m

Or use Cocoapods:

pod 'CustomIOSAlertView', '~> 0.9.5'

Change notes

• Fixed rotation for IOS8

• Removed 7 from the class name. Just use CustomIOSAlertView from now on, like: [[CustomIOSAlertView alloc] init];

• 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

   CustomIOSAlertView *alertView = [[CustomIOSAlertView 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: (CustomIOSAlertView *)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:^(CustomIOSAlertView *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

• Rotation: rotates wrong with the keyboard on
