Ii. business logic and knowledge points

 

1. There are two main classes: Class 1: homepage display class rootviewcontroller: uiimageview; Class 2: zombie class: zombieview: uiimageview.

2. play audio: # import <avfoundation/avaudioplayer. h>, which must be added,

 

 

Nsstring * deadpath = [[nsbundle mainbundle] pathforresource: @ "lose" oftype: @ "MP3"]; nsurl * deadurl = [nsurl fileurlwithpath: deadpath]; deadplayer = [[avaudioplayer alloc] initwithcontentsofurl: deadurl error: Nil]; [deadplayer preparetoplay];

3. Reminder box:

Uialertview * Alert = [[uialertview alloc] initwithtitle: @ "! ! "Message: @" You lost! "Delegate: Nil cancelbuttontitle: @" OK! "Otherbuttontitles: Nil]; [alert show];

[Alert release];

4. Import the package, which is generally placed in the. M file to prevent cross-compilation.

5. Timer,

Timer = [nstimer scheduledtimerwithtimeinterval: time target: Self

Selector: @ selector (MOVE) userinfo: Nil repeats: Yes];

 

[Timer invalidate]; // stop the timer

6. ry transform (matrix transformation)

// Change the zombie size

-(Void) changesize {// difficult, ry transform (matrix transformation) cgaffinetransform T = cgaffinetransformmakescale (2.0, 2.0); // scale the image and increase the animation [uiview animatewithduration: 0.35 animations: ^ {self. transform = T;} completion: ^ (bool finished) {// zoom out the animation [uiview animatewithduration: 0.35 animations: ^ {cgaffinetransform T1 = cgaffinetransformscale (self. transform, 0.5, 0.5); self. transform = T1;} completion: ^ (bool finished) {[self removefromsuperview] ;}];}
