ios语音识别功能

主要就是用到别人写好的一个第三方框架，，，在这很感谢愿意把自己的研究成果奉献给大家的人，不是谁都能做到这一点的。。

用的时候其实很简单。。。就一个文本框一个button。。。但是文本框，要用他们定义好的，，如下面代码，其他的就是把第三方写好的导入到自己项目里就行了。。。。。下面附带一个demo，，，如果自己项目里用到这个功能，只需导入需要的文件就行了。。。。。

// UILabel *myLabel = [[UILabel alloc]init];
// myLabel.contentMode = UIViewContentModeLeft;

textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
[textField setClearButtonMode:UITextFieldViewModeWhileEditing];
[textField setReturnKeyType:UIReturnKeyDone];

上面这几句用的很好。

#import "ViewController.h"
#import "VoiceTextField.h"
@interface ViewController ()

@end

@implementation ViewController {
    VoiceTextField *textField;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    textField = [[VoiceTextField alloc] initWithFrame:CGRectMake(0, 0, 200, 30)];
    textField.center = CGPointMake(self.view.frame.size.width/2, 50);
    textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    [textField setClearButtonMode:UITextFieldViewModeWhileEditing];
    [textField setReturnKeyType:UIReturnKeyDone];
    textField.placeholder = @"Please enter text";
    textField.textColor = [UIColor blackColor];
    [self.view addSubview:textField];
    [textField becomeFirstResponder];

    UIButton *btnTalk = [UIButton buttonWithType:UIButtonTypeCustom];
    UIImage *imgIcon = imageNamed(@"icon_mircophone2.png");
    [btnTalk setImage:imgIcon forState:UIControlStateNormal];
    [btnTalk setFrame:CGRectMake(0, 0, imgIcon.size.width, imgIcon.size.height)];
    btnTalk.center = CGPointMake(textField.frame.size.width+textField.frame.origin.x+btnTalk.frame.size.width/2, textField.frame.origin.y+textField.frame.size.height/2);
    [btnTalk addTarget:textField action:@selector(voiceMode) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btnTalk];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    [textField textMode];
}
