Question

我想更改我的UIBarButtonItems的图像，但没有色调，也没有调整大小。使用导航栏中的按钮就可以了。

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;

我不知道该怎么做。甚至可以在工具箱中删除BarButtonItem的色调？我只是希望我的图像没有任何变化。我该怎么办？

提前致谢！

问题在于你的UIButton初始化代码，试试这个：

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 */
