将plist文件中的数据赋给数组

NSString *thePath = [[NSBundle mainBundle] pathForResource:@"States" ofType:@"plist"];

NSArray *array = [NSArray arrayWithContentsOfFile:thePath];

点击键盘的Tap按钮，在不同的textField之间换行

//首先给不同的textField赋不同的且相邻的tag

//- (BOOL)textFieldShouldReturn:(UITextField *)textField

//{

//    if ([textField returnKeyType] != UIReturnKeyDone)

//    {

//        NSInteger nextTag = [textField tag] + 1;

//        UIView *nextTextField = [self.view viewWithTag:nextTag];

//        [nextTextField becomeFirstResponder];

//    }

//    else {

//        [textField resignFirstResponder];

//    }

//    return YES;

//} 

(BOOL)textFieldShouldReturn:(UITextField *)textField

有时候在 iPhone 游戏中，既要播放背景音乐，同时又要播放比如枪的开火音效。此时您可以试试以下方法

 

    NSString *musicFilePath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"wav"];       //创建音乐文件路径

    NSURL *musicURL = [[NSURL alloc] initFileURLWithPath:musicFilePath]; 

    AVAudioPlayer* musicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:musicURL error:nil];

    [musicURL release];

    [musicPlayer prepareToPlay];

    //[musicPlayer setVolume:1];            //设置音量大小

    //musicPlayer .numberOfLoops = -1;//设置音乐播放次数  -1为一直循环

 

要导入框架 AVFoundation.framework，头文件中 #import <AVFoundation/AVFoundation.h>；做成类的话则更方便。

 

隐藏状态栏[[UIApplication sharedApplication] setStatusBarHidden:YES];{

        NSInteger nextTag = [textField tag] + 1;

        UIView *nextTextField = [self.view viewWithTag:nextTag];

        [nextTextField becomeFirstResponder];

    }

    else {

        [textField resignFirstResponder];

    }

   

}
