Iphone sdk已经实现了语音播放功能，我们只需调用相应的组建既可。下面实现一个用户输入单词，点击播放语音，能够播放出相应的语音的例子。
源代码：http://easymorse-android.googlecode.com/svn/trunk/Say/
引入的组建：
声明：
#import <UIKit/UIKit.h>
@interface SayViewController : UIViewController {
IBOutlet UITextField *word;
}
@property (nonatomic,retain) UITextField *word;
-(IBAction)say;
@end
实现：
#import “SayViewController.h”
#import <AVFoundation/AVFoundation.h>
@implementation SayViewController
@synthesize word;
-(IBAction)say
{
NSString* urlString = [@"http://translate.google.com/translate_tts?q="stringByAppendingString:word.text];
NSURL* url = [[NSURL alloc] initWithString:[urlStringstringByReplacingOccurrencesOfString:@" " withString:@"+"]];
NSData* mp3Data = [[NSData alloc] initWithContentsOfURL:url];
[url release];
AVAudioPlayer* player = [[AVAudioPlayer alloc] initWithData:mp3Data error:nil];
[mp3Data release];
[player play];
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn’t have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren’t in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
