[！[带有标签栏控制器的模拟器] [1]] [1]

我创建了tabbar控制器，我想在其中放置图像，但图像变得更大..我在没有使用故事板的情况下以编程方式执行此操作。请帮助我

self.title=@"Speciality";
         NSArray *tabs;
        UIViewController *tab1 = [tabs objectAtIndex:0];
        tab1.tabBarItem.image = [UIImage imageNamed:@"home.png"];
        UIViewController *tab2 = [tabs objectAtIndex:1];
        tab2.tabBarItem.image = [UIImage imageNamed:@"special.png"];


        self.view =singleView;

试用此代码：

UIImage *image = [UIImage imageNamed:@"image.png"];
self.tabBarItem.image = [self imageWithImage:image scaledToSize:CGSizeMake(30, 30)];

- (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)newSize {
    UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
    [image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}
