How to clip larger images to fit into tabBar icons in tabBarController built programmatically.

cocoa, ios, objective-c, uitabbar, uitabbarcontroller

Solution

Sample_image is larger in size than is required by tab.

Try this piece of code as this will resize the required image and return an `UIImage` instance with `30x30` size (size required for `UITabbar`).

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

Add This method

- (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;
}

Problem

I have created a tab controller programmatically. Now, I wanted to add images to the different tabs, for which I used : ``` self.tabBarItem.image = [UIImage imageNamed:@"Sample_Image.png"]; ``` The problem is Sample_image is larger in size than is required by tab. So just want to know how can I clip the image to fit into tabs.
