    <p>yes ,it happens when you capture image in Portrait orientation of your device and use that image in your application, because the default orientation of image is Landscape in any IOS Device, so you need to change the orientation of image after picking from Gallery to use in your app.</p> <p>I have put code to achieve this</p> <p><strong>Objective-C code</strong></p> <pre><code>- (UIImage *)fixOrientationOfImage:(UIImage *)image { // No-op if the orientation is already correct if (image.imageOrientation == UIImageOrientationUp) return image; // We need to calculate the proper transformation to make the image upright. // We do it in 2 steps: Rotate if Left/Right/Down, and then flip if Mirrored.

    1. CODipen, yes I ended up using something similar. but I am facing another problem, I want my saved image to be cropped to the content that I am displaying in my square video container. but thats not the case, its even saving the part of the image that is not visible in the box.

    2. COfor that you needs to use some cropping methods to crop image, which are available in QuartzCore framework.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
