How to set height and width of a UIAlertView? - iphone

Question

I have a UIAlertView with an image and a large button.
The problem is that the default UIAlertView is a very small size. It's image cannot be seen properly.
So, I want to increase the height and width of the UIAlertView. In other words, I want to create a custom UIAlertView. What would be the way to do that?
Thanks.

I am sending you my code, I am showing a TableView in AlertView, perhaps it will help you.
in header file paste this code.
#import <UIKit/UIKit.h>
#interface aaViewController : UIViewController <UIAlertViewDelegate, UITableViewDelegate, UITableViewDataSource>{
UITextField *textfield;
UITableView *tableView1;
NSMutableArray *_data;
}
#property (nonatomic, retain) NSMutableArray *_data;
- (void) showAlertView;
- (void) doAlertViewWithTextView;
- (void) doAlertViewWithTableView;
#end
and in your imlpementation(.m) file paste this code.
#import "aaViewController.h"
#implementation aaViewController
#synthesize _data;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
self._data = [NSMutableArray arrayWithObjects:#"Najeeb", #"Furqan", #"Khalid", nil];
[self doAlertViewWithTableView];
}
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return YES;
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
- (void) doAlertViewWithTextView {
UIAlertView *alert = [[UIAlertView alloc] initWithFrame:CGRectMake(0, 0, 300, 550)];
alert.title = #"Textview";

alert.delegate = self;
[alert addButtonWithTitle:#"Cancel"];
[alert addButtonWithTitle:#"OK"];
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(12, 90, 260, 200)];
textView.text = #"This is what i am trying to add in alertView.\nHappy New Year Farmers! The new Winter Fantasy Limited Edition Items have arrived!

Note: In your AppDelegate add as subView to this.
