Adding UIImage to UIAlertView is not working as expected

Question

I am working on an app. I tried to add an UIIMage to UIAlertView using below code,

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Instruction"
                                                    message:@"Please TAP on Screen to Continue."
                                                   delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(220, 50, 32, 32)];
UIImage *img = [UIImage imageNamed:@"pendingImg.png"];
[imageView setImage:img];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    [alert setValue:imageView forKey:@"accessoryView"];
}else{
    [alert addSubview:imageView];
}
[alert show];

My image is of dimension 32 × 32 pixels. I am getting the alert as shown,

Should I add constraints to this image? or anything else to be made?

You shouldn't generally mess around with the view heirachy of UIAlertView. It would be far safer, not to mention better to create your own alert style view. — Jacob King, Feb 27 '17 at 11:38
Try changing the content mode of the imageView to aspect fit. — Adeel Miraj, Feb 27 '17 at 11:43
Check if it is working with UIImageView's contentMode UIViewContentModeScaleAspectFit — Mukesh Lokare, Feb 27 '17 at 11:45

@Anbu.Karthik My question is to make the image look normal, above post is to add image to UIAlertView — Forte Zhu, Feb 27 '17 at 11:53

You can set imageView contentMode to UIViewContentModeScaleAspectFit,

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Instruction"
                                                    message:@"Please TAP on Screen to Continue."
                                                   delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(220, 50, 32, 32)];
UIImage *img = [UIImage imageNamed:@"pendingImg.png"];
 imageView.contentMode = UIViewContentModeScaleAspectFit;

[imageView setImage:img];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
    [alert setValue:imageView forKey:@"accessoryView"];
}else{
    [alert addSubview:imageView];
}
[alert show];

Might be Anbu.Karthik suggested link comment also helpful for you.

if you are using lager size , it automaticaly fit in image view — Anbu.Karthik, Feb 27 '17 at 11:58
imageView.contentMode = UIViewContentModeScaleAspectFit; was the culprit :) — Forte Zhu, Feb 27 '17 at 12:07

try this

 UIAlertView* alert = [UIAlertView alloc] initWithTitle: @"Instruction" message: @"Please TAP on Screen to Continue." delegate:nil cancelButtonTitle:@"no" otherButtonTitles:@"yes", nil];

    UIImage* img = [UIImage imageNamed:@"pendingImg.png"];
    UIImageView* imgview = [UIImageView alloc] initWithFrame:CGRectMake(0, 0, img.size.width, img.size.height)];
    [img setImage:imgMyImage];

    [alert setValue: imgview forKey:@"accessoryView"];
    [alert show];

It just adds image to UIAlertVIew, somehow I am getting that with my code. — Forte Zhu, Feb 27 '17 at 11:54

UIAlertView* alert = [[UIAlertView alloc] initWithTitle: @"Instruction" message: @"Please TAP on Screen to Continue." delegate:nil cancelButtonTitle:@"no" otherButtonTitles:@"yes", nil];

   UIImage* img = [UIImage imageNamed:@"add.png"];
    UIImageView* imgview = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, img.size.width, img.size.height)];
    [imgview setImage:img];
    [alert setValue: imgview forKey:@"accessoryView"];
    [alert show];
}

Adding UIImage to UIAlertView is not working as expected
