Question

如何调整UITextField的大小以适应整个UINavigationBar？到目前为止，我有这个：

    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;

我基本上想要转换locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,246,31)];以适应UINavigationBar，可能使用sizeToFit，但不是100％确定如何实现它。

感谢。

Answer 1

您可以尝试

[self.navigationItem setTitleView:locationField];

见下面的代码：

    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];

没关系，通过切换CGRect来修复它：

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

到

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

SizeToFit导航栏项（UITextField）
