Create Uiview Free

Question

I need to create a new screen (Uiview) translucent in my app, in the style of an Iad iOS 7, but my problem is that I have no idea how to look for it.

What I found so far are old things, with many DEPRECATED methods or creating XIB and using QUARTZ.

NOTE: More or less in the model below, but translucent equal to iOS7 Notifications View.

Answer 1

To leave the UIView only translucent, you just need to set up the property alpha of UIView with a value less than 1.

A solution to achieve the effect shown in your image is to create a UIView with alpha < 1 serving as an intermediate mask between the UIView in the background (background) and the UIView in the foreground (foreground).

There is also another effect called Blur which is being widely used lately (especially after the launch of iOS 7). The creation of this effect is more sophisticated than the previous case, however there are several tutorials and codes open source available on the internet dealing with the subject.

Answer 2

If it is really the Blur you want, just "steal" the layer of a Uitoolbar, as this tutorial here: http://www.guilmo.com/how-to-make-a-realtime-blur-on-ios-7/

Answer 3

Take a look at the https://github.com/m1entus/MZFormSheetController

You can play a lot. You create a view controller the way you and the storyboard you arrow the Storyboard ID to be able to instantiate it in the code, in the example below: "Nav".

To open a new View Controller inside the Form Sheet:

UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"nav"];

// abre o novo view controller
[self mz_presentFormSheetController:vc animated:YES completionHandler:^(MZFormSheetController *formSheetController) {
   //seu código
}];

Mzformsheetcontroller automatically leaves the translucent background and performs the animations by appearing and disappearing. You can set up some things, like blurring the background:

[[MZFormSheetBackgroundWindow appearance] setBackgroundBlurEffect:YES];
[[MZFormSheetBackgroundWindow appearance] setBlurRadius:5.0];
[[MZFormSheetBackgroundWindow appearance] setBackgroundColor:[UIColor clearColor]];
