ios - 问题 TextField 更改为搜索文本

Question

我正在为我的文本创建文本字段。

当我创建它时，它会显示一条附加到我的文本字段的线。

我附上了这张图片..

我的代码是

-(void)createTextField{

    if (([[UIDevice currentDevice]orientation]==UIDeviceOrientationLandscapeLeft)||([[UIDevice currentDevice]orientation]==UIDeviceOrientationLandscapeRight)) {
        [text setFrame:CGRectMake(640, 15, 300,40)];    
    }
    else {
        [text setFrame:CGRectMake(390,15,300,50)];
    }


    text.font = [UIFont systemFontOfSize:20];
    text.layer.cornerRadius = 20;
    text.delegate=self; 
    [text setTextColor:[UIColor blackColor]];
    text.alpha=1.0;
    text.autocorrectionType = UITextAutocorrectionTypeNo;
    text.returnKeyType=UIReturnKeySearch;
    UIImageView *searchLogo = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"icon-search-black.png"]];
    [text  setLeftView:searchLogo];
    [text setLeftViewMode:UITextFieldViewModeAlways];
    [searchLogo release];
    text.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    text.borderStyle=UITextBorderStyleRoundedRect;
    [text setBackgroundColor:[UIColor whiteColor]];

    [text setHidden:NO];
    [self addSubview:text];
    [text becomeFirstResponder];
}

它必须是 borderStyle 踢进来，即

text.borderStyle = UITextBorderStyleRoundedRect;

您可以使用 UITextBorderStyleNone，因为您已经使用 cornerRadius 自定义了边框样式。
