SizeToFit导航栏项目(UITextField)

Question

如何调整UITextField大小以适合整个UINavigationBar？到目前为止，我有这样的想法：

    locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,246,31)];
    locationField.delegate = self;
    locationField.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    locationField.textColor = [UIColor colorWithRed:102.0/255 green:102.0/255 blue:102.0/255 alpha:1.0];
    locationField.textAlignment = UITextAlignmentLeft;
    locationField.borderStyle = UITextBorderStyleRoundedRect;
    locationField.font = [UIFont fontWithName:@"Helvetica" size:15];
    locationField.autocorrectionType = UITextAutocorrectionTypeNo;
    locationField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;

我基本上想使用locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,246,31)];来适应UINavigationBar，可能是使用sizeToFit，只是不是100%确定如何实现它。

谢谢。

您可以尝试使用

[self.navigationItem setTitleView:locationField];

请看下面的代码：

    UITextField *locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,246,31)];
    locationField.delegate = self;
    locationField.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    locationField.textColor = [UIColor colorWithRed:102.0/255 green:102.0/255 blue:102.0/255 alpha:1.0];
    locationField.textAlignment = UITextAlignmentLeft;
    locationField.borderStyle = UITextBorderStyleRoundedRect;
    locationField.font = [UIFont fontWithName:@"Helvetica" size:15];
    locationField.autocorrectionType = UITextAutocorrectionTypeNo;
    locationField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    [self.navigationItem setTitleView:locationField];
    [locationField release];

不要紧，通过将CGRect从以下位置切换得到修复：

UITextField *locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,246,31)];

至

UITextField *locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,300,31)];
