                                                             target:self action:@selector(submitClicked:)];

//Change submit button attributes here as you want
[submit setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                   [UIFont fontWithName:@"Helvetica-Bold" size:18.0], NSFontAttributeName,
                                   [UIColor whiteColor], NSForegroundColorAttributeName,

如果您想更改整个应用程序工具栏中的更改，请使用

[UIToolbar appearance].tintColor = [UIColor redColor];
[UIToolbar appearance].barTintColor = [UIColor greenColor];

您也可以使用以下代码进行更改：

 NSDictionary *attributes = @{
                                 NSForegroundColorAttributeName: [UIColor colorWithRed:220.0/255.0 green:104.0/255.0 blue:1.0/255.0 alpha:1.0],

                                 NSFontAttributeName: [UIFont fontWithName:@"Arial" size:16.0]
                                 };
    [[UIBarButtonItem appearance] setTitleTextAttributes:attributes forState:UIControlStateNormal];
