UIAlertView addSubview in iOS7

Solution 1:

Here is a project on Github to add any UIView to an UIAlertView-looking dialog on iOS7.

(Copied from this StackOverflow thread.)

Solution 2:

It took me only 1 day to create my own alert view that looks exactly like Apple's

1. Take a screenshot of Apple's alert for reference (font sizes, spacings, width)
2. Create a xib with title, message, custom view and tables for buttons (Apple uses tables instead of UIButton now, default table cell is good enough). Note you need 3 button tables: two for left and right buttons (whenever the number of buttons is 2), another one for the other cases (one button or more than 2 buttons).

3. Implement all the methods from UIAlertView on your custom alert.

4. Show/Dismiss - you can create a specific modal window for your alerts but I just put my alerts on top of my root view controller. Register your visible alerts to a static array. If showing the first alert/dismissing the last, change tint mode of your window/view controller to dimmed/to automatic and add/remove a dimming view (black with alpha = 0.2).

5. Blurred background - use Apple's sample code (I used opaque white)
6. 3D dynamic effects - use Apple's sample code (5 lines of code). If you want a nice effect, take a slightly bigger snapshot in step 5 and add inverse animators for alert background and foreground.

EDIT:

Both blurred background and the paralax effect sample code can be found in "iOS_RunningWithASnap" WWDC 2013 sample code

Paralax effect:

UIInterpolatingMotionEffect* xAxis = [[[UIInterpolatingMotionEffect alloc] initWithKeyPath:@"center.x"
                                                                                     type:UIInterpolatingMotionEffectTypeTiltAlongHorizontalAxis] autorelease];
xAxis.minimumRelativeValue = [NSNumber numberWithFloat:-10.0];
xAxis.maximumRelativeValue = [NSNumber numberWithFloat:10.0];

UIInterpolatingMotionEffect* yAxis = [[[UIInterpolatingMotionEffect alloc] initWithKeyPath:@"center.y"
                                                                                     type:UIInterpolatingMotionEffectTypeTiltAlongVerticalAxis] autorelease];
yAxis.minimumRelativeValue = [NSNumber numberWithFloat:-10.0];
yAxis.maximumRelativeValue = [NSNumber numberWithFloat:10.0];

UIMotionEffectGroup *group = [[[UIMotionEffectGroup alloc] init] autorelease];
group.motionEffects = @[xAxis, yAxis];
[self addMotionEffect:group];

The blurred background is the only complicated thing. If you can use an opaque color instead, use it. Otherwise it's a lot of experimenting. Also note that blurred background is not a good solution when the background is dark.

For the show/dismiss animationg, I am using the new spring animation method:

void (^animations)() = ^{
    self.alpha = 1.0f;
    self.transform = CGAffineTransformIdentity;
};

self.alpha = 0.0f;
self.transform = CGAffineTransformMakeScale(0.5f, 0.5f);

[UIView animateWithDuration:0.3
                      delay:0.0
     usingSpringWithDamping:0.7f
      initialSpringVelocity:0.0f
                    options:UIViewAnimationOptionCurveLinear
                 animations:animations
                 completion:^(BOOL completed) {
                         //calling UIAlertViewDelegate method
                     }];

Solution 3:

I wrote a full implementation of UIAlertView that mimics the complete UIAlertView API, but adds the contentView property we've all wanted for so long: SDCAlertView.

Solution 4:

For those who love simple and effective methods with out having to write lines of code. Here is a cool solution without using any other private frame works for adding subviews to ios 7 alert views,i.e.

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

Sample code for better understanding,

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(180, 10, 85, 50)];
UIImage *wonImage = [UIImage imageNamed:@"image.png"];
[imageView setImage:wonImage];

//check if os version is 7 or above
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
      [alertView setValue:imageView forKey:@"accessoryView"];
}else{
      [alertView addSubview:imageView];
}

Hope it helps some one,thanks :)

Solution 5:

For IOS7

UIAlertView *alertView1 = [[UIAlertView alloc] initWithTitle:@"Enter Form Name" 
                                               message:@""
                                               delegate:self 
                                               cancelButtonTitle:@"Cancel"
                                               otherButtonTitles:@"Ok", nil];
alertView1.alertViewStyle = UIAlertViewStyleSecureTextInput;
UITextField *myTextField = [alertView1 textFieldAtIndex:0];
[alertView1 setTag:555];
myTextField.keyboardType=UIKeyboardTypeAlphabet;

[alertView1 show];
