How to Add Subview Inside Uialertview for iOS 7

How to add subview inside UIAlertView for iOS 7?

You can really change accessoryView to customContentView in iOS7 (and it seems that in iOS8 as well) UIAlertView

[alertView setValue:customContentView forKey:@"accessoryView"];

Try this code:

UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"TEST" message:@"subview" delegate:nil cancelButtonTitle:@"NO" otherButtonTitles:@"YES", nil];
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
[av setValue:v forKey:@"accessoryView"];
v.backgroundColor = [UIColor yellowColor];
[av show];

Remember that you need set custom accessoryView before the call [alertView show]

We can add subviews to UIAlerView by adding subview to the presentedViewController's view when UIAlertView is presented. I have accessed UIAlertView like following way :

NSArray *subviews = [UIApplication sharedApplication].keyWindow.rootViewController.presentedViewController.view.subviews;

I have created a subclass of UIAlerView :

Header File :

@interface MLKLoadingAlertView : UIAlertView

- (id)initWithTitle:(NSString *)title;

@end

Implementation File :

#import "MLKLoadingAlertView.h"

#define ACTIVITY_INDICATOR_CENTER   CGPointMake(130, 90)

@implementation MLKLoadingAlertView

- (id)initWithTitle:(NSString *)title
{
    if ( self = [super init] )
    {
        self.title = title;
        self.message = @"\n\n";

        [self setDelegate:self];
    }

    return self;
}

// You can Customise this based on your requirement by adding subviews.
- (void)didPresentAlertView:(UIAlertView *)alertView
{
    NSArray *subviews = [UIApplication sharedApplication].keyWindow.rootViewController.presentedViewController.view.subviews;

    if( subviews.count > 1 )
    {
        // iOS while presenting an alertview uses a presening view controller. That controller's view has several subviews. I have picked one
        // subview from it which has frame similar to the alertview frame.
        UIView *presentedView = [subviews objectAtIndex:1];

         UIActivityIndicatorView *customActivityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
        [customActivityIndicator startAnimating];
        customActivityIndicator.center = ACTIVITY_INDICATOR_CENTER;

        [presentedView addSubview:customActivityIndicator];
    }
}

@end

In - (void)didPresentAlertView:(UIAlertView *)alertView method I have added the subviews to UIAlertView by accessing Presented View Controller's view.
