详解iOS App中调用AVAudioPlayer播放音频文件的用法
要给工程中添加音频,首先要导入音频的框架AVFoundation.framework
然后新建一个类继承于UIViewController,我这里就叫FirstVC.
首先在AppDelegate.m中初始化根视图
#import"AppDelegate.h" #import"FirstVC.h" @implementationAppDelegate
-(void)dealloc { [_windowrelease]; [superdealloc]; }
-(BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions { self.window=[[[UIWindowalloc]initWithFrame:[[UIScreenmainScreen]bounds]]autorelease]; //Overridepointforcustomizationafterapplicationlaunch. FirstVC*firstVC=[[FirstVCalloc]init]; self.window.rootViewController=firstVC; [firstVCrelease]; self.window.backgroundColor=[UIColorwhiteColor]; [self.windowmakeKeyAndVisible]; returnYES; }
