IOS7, 8 modal translucent pop-up box

Implementation of Jump method in Source controller

Mkdialogcontroller *controller = [[Mkdialogcontroller alloc] init];

Controller.modaltransitionstyle = Uimodaltransitionstylecrossdissolve;

if ([[Uidevice currentdevice].systemversion Floatvalue] >= 8.0) {

Controller.providespresentationcontexttransitionstyle = YES;

Controller.definespresentationcontext = YES;

Controller.modalpresentationstyle = Uimodalpresentationovercurrentcontext;

[Self Presentviewcontroller:controller animated:yes completion:nil];

} Else {

Self.view.window.rootViewController.modalPresentationStyle = Uimodalpresentationcurrentcontext;

[Self Presentviewcontroller:controller animated:no completion:nil];

Self.view.window.rootViewController.modalPresentationStyle = Uimodalpresentationfullscreen;

}

But there is no animation effect after jump, need to be optimized
