Ios-ipad Uipopovercontroller

In the ipad development, there is a very interesting view controller, UIPOPOVERCONTROLLR, its initialization must be set up a "content view", the equivalent of itself just as a "container", and the content of the display needs another view.

Initialization

-(void) Show: (UIButton *) button{

Tableviewcontroller *tb=[[tableviewcontroller Alloc]initwithnibname:nil Bundle:nil];

Tableviewcontroller *popoverviewcontroller = [[Tableviewcontroller alloc]initwithnibname:nil Bundle:nil];

Popoverviewcontroller.title = @ "Choose the color you like";

Uinavigationcontroller *nav = [[Uinavigationcontroller alloc]

Initwithrootviewcontroller:popoverviewcontroller];

Self.poc = [[Uipopovercontroller alloc] initwithcontentviewcontroller:nav];

[Self.poc presentPopoverFromRect:button.bounds Inview:button Permittedarrowdirections:uipopoverarrowdirectionup Animated:yes];

}
