ios - UIButtonTypeDetailDisclosure 颜色变化

Question

我已将 UIButtonTypeDetailDisclosure 的图像更改为下图，但问题是图像变成了蓝色。我的问题在哪里？

- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation
{
*infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

[infoButton setImage:[UIImage imageNamed:@"carcar.png"] forState: UIControlStateNormal];

pinView.rightCalloutAccessoryView = infoButton;
} 

最后更新:用最后一个 infoButton.frame 解决。

    UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeCustom];

    UIImage *carImage = [UIImage imageNamed:@"carcar.png"];

    if ([carImage respondsToSelector:@selector(imageWithRenderingMode:)])
    {
        carImage = [carImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    }

    [infoButton setImage:carImage forState: UIControlStateNormal];

    infoButton.frame = CGRectMake(0, 0, 32, 32);

    pinView.rightCalloutAccessoryView = infoButton;

我遇到了类似的问题并按如下方式解决(使用您的代码):

UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[infoButton setTintColor:[UIColor clearColor]];

UIImage *carImage = [[UIImage imageNamed:@"carcar.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

[infoButton setBackgroundImage:carImage forState:UIControlStateNormal];
