Does not work on iOS 8 App Extension - 2 Errors

[Supertecnoboff]

Hi @dogo

I have two errors with this awesome app. One of them I managed to resolve, but the other I have not be able to solve. I am trying to implement SCLAlertView in an iOS 8 Extension (Widget).

The first error I got is in the SCLAlertView.m file in the viewWillLayoutSubviews method. There is a bit of code which determines if the app is in landscape, it doesn't work on an iOS 8 Extension, because UIApplication sharedApplication is not available.

So this is what I did to fix it:

if (SYSTEM_VERSION_LESS_THAN(@"8.0"))
    {
        if (self.view.frame.size.width > self.view.frame.size.height) {
            NSLog(@"Landscape");

            CGSize ssz = sz;
            sz = CGSizeMake(ssz.height, ssz.width);
        }

        else {
            NSLog(@"Portrait");
        }

        /*
        // iOS versions before 7.0 did not switch the width and height on device roration
        if (UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation]))
        {
            CGSize ssz = sz;
            sz = CGSizeMake(ssz.height, ssz.width);
        }*/
    }

The second issue I am having which I don't know how to fix is in the UIImage+ImageEffects.m file. There is a method at the very bottom of the source file called convertViewToImage - the first line of this method uses UIApplication sharedApplication so it won't work on iOS 8 Extensions. Do you know how to fix it?

+ (UIImage *)convertViewToImage
{
    UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];

    UIView *keyView = [self.view];
    CGRect rect = [keyWindow bounds];
    UIGraphicsBeginImageContextWithOptions(rect.size, YES, 0.0f);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [keyWindow.layer renderInContext:context];
    UIImage *capturedScreen = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return capturedScreen;
}

@dogo Also in a iOS 8 Extension Widget, the alert popup works but its appears at the bottom of the widget, not in the centre, do you know why this is the case and how to fix it?

HI @Supertecnoboff , which version are you using? the latest version uses
+ (UIImage *)convertViewToImage:(UIView *)view

And you need to use the methods that uses UIViewController as first parameter

@dogo Ok just upgraded to the new version, but sorry its worse. It has lots of deprecated warnings and it uses UIApplication sharedApplication even more now. Its not appropriate for use with iOS 8 widgets. So I think I will return to the previous version.

On a side note, I did find out why it was not showing in the middle of a widget, the issue arrises with this line of code: CGSize sz = [UIScreen mainScreen].bounds.size;

You have to manually set the size of your widget height property for it to work with widgets.

Right well I think I will close this now as I now longer have these issues. I fixed them by doing the following:

1. For the code which checks the device orientation:

if (UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation]))
        {
            CGSize ssz = sz;
            sz = CGSizeMake(ssz.height, ssz.width);
        }*/

I simply just removed it, as my app is for iOS 8 and higher only, so I don't even need that bit of code.

2. For the issue of displaying the alert in he correct vertical position in iOS 8 widgets, I am looking into either passing the value of the views height in manually or getting it to detect the views height automatically (which I am currently testing with).

3. Lastly, I did not upgrade to the latest version as its full of deprecations and uses UIApplication sharedApplication too much.

I made some changes related to extension view bounds.
Delete if (UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation])) { CGSize ssz = sz; sz = CGSizeMake(ssz.height, ssz.width); }
is really needed ? The presence in the code break something?

I'm curious, how the alert is present using as extension ? could you send me a screenshot or post here ehehe
