    <p>I'm having an issue whenever I am saving a .png image to my iOS Applications.</p> <pre><code>-(UIImage *) getImageFromURL:(NSString *)fileURL { UIImage * result; NSData * data = [NSData dataWithContentsOfURL:[NSURL URLWithString:fileURL]]; result = [UIImage imageWithData:data]; return result; } -(void) saveImage:(UIImage *)image withFileName:(NSString *)imageName ofType:(NSString *)extension inDirectory:(NSString *)directoryPath { if ([[extension lowercaseString] isEqualToString:@"png"]) { [UIImagePNGRepresentation(image) writeToFile:[directoryPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.%@", imageName, @"png"]] options:NSAtomicWrite error:nil]; } else if ([[extension lowercaseString] isEqualToString:@"jpg"] || [[extension lowercaseString] isEqualToString:@"jpeg"]) { [UIImageJPEGRepresentation(image, 1.0) writeToFile:[directoryPath stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.%@", imageName, @"jpg"]] options:NSAtomicWrite error:nil]; } else { NSLog(@"Image Save Failed\nExtension: (%@) is not recognized, use (PNG/JPG)", extension); } } </code></pre> <p>The code above is what I'm using to download the images with, passing it a url to an image and then "png" as the file type.</p> <p>For some reason, the image saves onto the devices, but it saves in an incorrect format. I've tested this by pulling up the iPhone Simulator program application folder and looking at the images directly. They are indeed saved, but even Mac OS X can't open them up as "Images" with Preview.</p> <p>Am I doing something wrong? These images are actual png images that I'm just downloading to the device. This was previously working a week ago, now it isn't.</p>

    2. COThis is the code that was working before that I had, but then last week it just suddenly stopped working properly, on the simulator and on actual devices. It literally worked one day, then the next day, no changes were made, nothing, and it just stopped working.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
