Today, Liu Guobin teacher taught a demo of the actual combat, write music player

1, if in the Viewcontroller jump to other pages, another viewcontroller is storyboard dragged out, the initialization of the page needs to use Self.stroy re-call method, Instantiateviewcontrollerwithidentifier

2, but if the other page is not Viewcontroller and then jump to another page, the page is also used Stroyboard dragged out, then use Uistoryboard through their own mainstoryboard mark "Main" First, create an object to initialize another page with this object.

Uistoryboard *storyboard = [Uistoryboard storyboardwithname:@ "Main" bundle:nil];

Macro definition automatically gets the size of the screen

#define Screen_size [UIScreen mainscreen].bounds.size

Feature implementation jumps from the first page to Tabbarcontroller

@implementation Viewcontroller

-(void) Viewdidload {

[Super Viewdidload];

Uiscrollview *sc=[[uiscrollview Alloc]initwithframe:[uiscreen Mainscreen].bounds];

Sc.pagingenabled=yes;

for (int i=0; i<5; i++) {

Uiimageview *iv=[[uiimageviewalloc]initwithframe:cgrectmake (i*screen_size.width, 0, SCREEN_SIZE.width, SCREEN_ Size.Height)];

Iv.image=[uiimage imagenamed:[nsstringstringwithformat:@ "Welcome_3.0_%d.jpg", i+1]];

[SC Addsubview:iv];

}

CGRect bnfram=cgrectmake (0, 0, screen_size.width, screen_size.height);

UIButton *bn=[[uibutton Alloc]initwithframe:bnfram];

[Bn addtarget:self Action: @selector (MOO) forcontrolevents:uicontroleventtouchupinside];

[SC Addsubview:bn];

sc.delegate=self;

Considering the problem of screen size adaptation, the content of this contentsize takes a dynamic

Sc.contentsize=cgsizemake (5*screen_size.width, 667);

[Self.view ADDSUBVIEW:SC];

}

-(void) moo{
