WCAlertView

iOS 7 and above not supported !

In iOS7, the UIAlertView window does not appear in -[UIApplication windows]. In fact, the UIAlertView itself is never added to any window, -[UIAlertView window] is always nil. Instead, the alert view manages a variety of undocumented views placed in -[UIApplication keyWindow] with no reference back to the alert view.

Info

WCAlertView is a subclass from UIAlertView with possibility of customization.

You can easly customize your UIAlertView.

How To Use

There are a couple of predefined styles, you might use them instead of writing your own.

WCAlertView supports blocks.

You might set default appearance for all WCAlertView's:

[WCAlertView setDefaultStyle:WCAlertViewStyleWhite];

Set default appearnce block for all WCAlertView's inside AppDelegate (similar to UIAppearance proxy)

[WCAlertView setDefaultCustomiaztonBlock:^(WCAlertView *alertView) {
        alertView.labelTextColor = [UIColor colorWithRed:0.11f green:0.08f blue:0.39f alpha:1.00f];
        alertView.labelShadowColor = [UIColor whiteColor];

        UIColor *topGradient = [UIColor colorWithRed:1.0f green:1.0f blue:1.0f alpha:1.0f];
        UIColor *middleGradient = [UIColor colorWithRed:0.93f green:0.94f blue:0.96f alpha:1.0f];
        UIColor *bottomGradient = [UIColor colorWithRed:0.89f green:0.89f blue:0.92f alpha:1.00f];
        alertView.gradientColors = @[topGradient,middleGradient,bottomGradient];

        alertView.outerFrameColor = [UIColor colorWithRed:250.0f/255.0f green:250.0f/255.0f blue:250.0f/255.0f alpha:1.0f];

        alertView.buttonTextColor = [UIColor colorWithRed:0.11f green:0.08f blue:0.39f alpha:1.00f];
        alertView.buttonShadowColor = [UIColor whiteColor];
}];

If you want to use UITextField for password or plain input text, use UIAlertViewStyle (available since iOS 5.x).

[WCAlertView showAlertWithTitle:@"Some title" message:@"Custom message" customizationBlock:^(WCAlertView *alertView) {

        alertView.alertViewStyle = UIAlertViewStyleSecureTextInput;

    } completionBlock:^(NSUInteger buttonIndex, WCAlertView *alertView) {

    } cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];

How to use:

[WCAlertView showAlertWithTitle:@"Custom AlertView Title" 
                        message:@"You can do a lot of additional setup using WCAlertView." 
                        customizationBlock:^(WCAlertView *alertView) {

                            alertView.style = WCAlertViewStyleVioletHatched;

    } completionBlock:^(NSUInteger buttonIndex, WCAlertView *alertView) {

    } cancelButtonTitle:@"Cancel" otherButtonTitles:@"Okay",nil];
WCAlertView *alert = [[WCAlertView alloc] initWithTitle:@"Custom AlertView Title" 
                                                message:@"You can do a lot of additional setup using WCAlertView." 
                                               delegate:nil cancelButtonTitle:@"Cancel" 
                                               otherButtonTitles:@"Okay", nil];

    alert.style = WCAlertViewStyleVioletHatched;

    [alert show];
