Ios – Table view doesn’t scroll when I use gesture recognizer

iosuigesturerecognizeruitableview

My app has a table view (with a scroll-into of course) and this view slides on and off with a gesture recognizer (like on the Facebook app).

If I use a button to slide [the table view onto the screen], it works fine but when I use a gesture recognizer, the table view can't be scrolled anymore.

Here is the code of gesture recognizer with the problem:

[self.view addGestureRecognizer:self.slidingViewController.panGesture];

Somebody have an idea?

Your gesture is probably preventing the scroll view gesture from working because by default only 1 gesture can be recognising at a time. Try adding yourself as the delegate of your gesture and implementing:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

self.slidingViewController.panGesture.delegate = self;

also, add <UIGestureRecognizerDelegate> to the list of protocols you implement

Ios – The simplest way to resize an UIImage

The simplest way is to set the frame of your UIImageView and set the contentMode to one of the resizing options.

Or you can use this utility method, if you actually need to resize an image:

+ (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)newSize {
    //UIGraphicsBeginImageContext(newSize);
    // In next line, pass 0.0 to use the current device's pixel scaling factor (and thus account for Retina resolution).
    // Pass 1.0 to force exact pixel size.
    UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
    [image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();    
    UIGraphicsEndImageContext();
    return newImage;
}

Example usage:

#import "MYUtil.h"
…
UIImage *myIcon = [MYUtil imageWithImage:myUIImageInstance scaledToSize:CGSizeMake(20, 20)];

Ios – How to scroll to the bottom of a UITableView on the iPhone before the view appears

I believe that calling

 tableView.setContentOffset(CGPoint(x: 0, y: CGFloat.greatestFiniteMagnitude), animated: false)

will do what you want.
