小编har*_*eng的帖子

我正在使用Objective-C编写的第三个CocoaPods库来截取UITextView的截图.对于iOS 8来说没关系,但是在我更改了iOS 9和Swift 2的语法后,它会抛出一个错误:

由于未捕获的异常'CALayerInvalidGeometry'而终止应用程序,原因:'子层具有非有限位置[inf inf]'

这是来自图书馆的代码:

- (UIImage *)screenshotForCroppingRect:(CGRect)croppingRect
{
    UIGraphicsBeginImageContextWithOptions(croppingRect.size, NO, [UIScreen mainScreen].scale);
    // Create a graphics context and translate it the view we want to crop so
    // that even in grabbing (0,0), that origin point now represents the actual
    // cropping origin desired:
    CGContextRef context = UIGraphicsGetCurrentContext();
    if (context == NULL) return nil;

    NSLog(@"hiii :%f" , croppingRect.size.width);

    CGContextTranslateCTM(context, -croppingRect.origin.x, -croppingRect.origin.y);

    [self layoutIfNeeded];
    [self.layer renderInContext:context];

    UIImage *screenshotImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return screenshotImage;
}

问题是这一行:

[self.layer renderInContext:context];

我意识到这是因为我试图拍摄包含UIScrollView的UIView的快照.如果我删除UIScrollView子视图,则错误消失. …

有没有人有类似的情况？因此,应用程序打开,推送通知警报显示询问用户是否允许接收推送通知,测试单击"不允许",即使我有以下代码:

func testClickSystemAlert(){
        let app = XCUIApplication();
        XCUIApplication().alerts["“???” Would Like to Send You Notifications"].buttons["Allow"].tap()
    }

这是print的输出(XCUIApplication().debugDescription);

有一个单元格包含一个集合视图。我已经使用

cell.accessibilityLabel = @"daren_shangjia_0001_add_new_photo_album";

然后在 XCTest 中，我做

print(app.debugDescription);

我没有看到我提供的辅助功能标签。

Xcode 版本 8.2 (8C38)

有没有办法检测 UITests 是否在真实设备上运行？

谢谢
