Ios 为iPhone应用定制工具栏

我想更改我的uibarbuttonims的图像，但不带颜色，也不调整大小。 我在导航栏上的按钮很好

这是我的方法：

    UIButton *mySettingsButton = [UIButton buttonWithType:UIButtonTypeCustom];
    UIImage *settingsImage = [UIImage imageNamed:@"settings-greyscale.png"];
    mySettingsButton.frame = CGRectMake(0.0, 0.0, settingsImage.size.width, settingsImage.size.height);
    [mySettingsButton setBackgroundColor:[UIColor clearColor]];
    [mySettingsButton setImage:settingsImage forState:UIControlStateNormal];
    [mySettingsButton addTarget:self action:@selector(performSettingsSegue)  forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *mySettingsBarButton = [[UIBarButtonItem alloc] initWithCustomView:mySettingsButton];
    UIBarButtonItem *settingsBarButton = (UIBarButtonItem *)[self.view viewWithTag:1000];
    settingsBarButton = mySettingsBarButton;

我不知道该怎么办。甚至有可能去除工具箱中的巴布托石？我只想我的形象没有任何变化。 我该怎么办

提前谢谢

问题出在UIButton初始化代码中，请尝试以下操作：

UIButton *mySettingsButton = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *settingsImage = [UIImage imageNamed:@"settings-greyscale.png"];
mySettingsButton.frame = CGRectMake(0.0, 0.0, sttingsImage.size.width, settingsImage.size.height);
/* then your code */
