A. Requirements1. Similar to QQ, top or bottom of the window conversion navigation bar 2. Add content to each page B.uitabbarcontroller1. Basic concept: (1) Content height iOS7 before content height: screen height-status bar height 44-bottom navigation bar height 49ios7 and after, content height is full screen 2. Using code creation Initialization (1) to create a Uitabbarcontrolleruitabbarcontroller use step
    • Initialize Uitabbarcontroller
    • Set the Rootviewcontroller for UIWindow to Uitabbarcontroller
    • Depending on the case, add the corresponding number of sub-controllers by the Addchildviewcontroller method
(2) Add a sub-controller Uitabbarcontroller There are 2 ways to add a controller
    • Adding a single child controller
-(void) Addchildviewcontroller: (Uiviewcontroller *) Childcontroller;

    • Set up a sub-controller array
@property (nonatomic,copy) Nsarray *viewcontrollers;  If the Uitabbarcontroller has n sub-controllers, then there will be N Uitabbarbutton inside Uitabbar as child controls if Uitabbarcontroller has 4 sub-controllers, then the structure of Uitabbar is roughly as shown Appdelegate:
1-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchoptions {2     //Override point for customization after application launch.3    4     //Set Window5Self.window =[[UIWindow alloc] init];6Self.window.frame =[[UIScreen mainscreen] bounds];7Self.window.backgroundColor =[Uicolor Graycolor];8 [Self.window makekeyandvisible];9    Ten     One     //set up a Uitabbarcontroller AUitabbarcontroller *tabbarcontroller =[[Uitabbarcontroller alloc] init]; -Self.window.rootViewController =Tabbarcontroller; -     the     //Adding a child controller -Uiviewcontroller *C1 =[[Uiviewcontroller alloc] init]; -C1.view.backgroundColor =[Uicolor Redcolor]; - //[Tabbarcontroller addchildviewcontroller:c1]; +     -Uiviewcontroller *C2 =[[Uiviewcontroller alloc] init]; +C2.view.backgroundColor =[Uicolor Bluecolor]; A //[Tabbarcontroller ADDCHILDVIEWCONTROLLER:C2]; at     -Uiviewcontroller *C3 =[[Uiviewcontroller alloc] init]; -C3.view.backgroundColor =[Uicolor Greencolor]; -     -Tabbarcontroller.viewcontrollers =@[c1,c2,c3]; -     in     -     returnYES; to}
(3) Set the navigation bar option style Uitabbarbutton What is displayed inside, determined by the Tabbaritem property of the corresponding sub-controller


Uitabbaritem has the following properties that affect the content of Uitabbarbutton
Title text
@property (nonatomic,copy) NSString *title;

Icon
@property (Nonatomic,retain) UIImage *image;

Icon When selected
@property (Nonatomic,retain) UIImage *selectedimage;

Reminder number @property (nonatomic,copy) NSString *badgevalue; Appdelegate:
1-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchoptions {2     //Override point for customization after application launch.3    4     //Set Window5Self.window =[[UIWindow alloc] init];6Self.window.frame =[[UIScreen mainscreen] bounds];7Self.window.backgroundColor =[Uicolor Graycolor];8 [Self.window makekeyandvisible];9    Ten     One     //set up a Uitabbarcontroller AUitabbarcontroller *tabbarcontroller =[[Uitabbarcontroller alloc] init]; -Self.window.rootViewController =Tabbarcontroller; -     the     //Adding a child controller -Uiviewcontroller *C1 =[[Uiviewcontroller alloc] init]; -C1.view.backgroundColor =[Uicolor Redcolor]; -C1.tabBarItem.title =@"Red"; + //[Tabbarcontroller addchildviewcontroller:c1]; -     +Uiviewcontroller *C2 =[[Uiviewcontroller alloc] init]; AC2.view.backgroundColor =[Uicolor Bluecolor]; atC2.tabBarItem.title =@"Blue"; - //[Tabbarcontroller ADDCHILDVIEWCONTROLLER:C2]; -     -Uiviewcontroller *C3 =[[Uiviewcontroller alloc] init]; -C3.view.backgroundColor =[Uicolor Greencolor]; -C3.tabBarItem.title =@"Green"; in     -Tabbarcontroller.viewcontrollers =@[c1,c2,c3]; to     +     -     returnYES; the}
3. Use storyboard to create initialization (1) drag into Uitabbarcontroller (2) drag into n Uiviewcontroller to use (3) to set the Uitabbarcontroller sub-controller in sequence (4) Set the Tabbaritem out of the sub-controller: Note: Selected image is not set, the system will automatically program the original artwork blue as Selected image4. The life cycle of the sub-controller (1) The life cycle of a single sub-controller is the same as the normal controller life cycle
