SizeToFit导航栏项目（UITextField）

Question

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

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; 

我基本上要翻locationField = [[UITextField alloc] initWithFrame:CGRectMake(37,7,246,31)];以适应UINavigationBar的，可能使用sizeToFit，只要不是100％确定如何实现它。

谢谢。

你可以尝试

[self.navigationItem setTitleView:locationField]; 

下面

见代码：

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，得到它固定的由切换的CGRect：

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

到

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