我正在使用此方法截取我的应用的屏幕截图:
+ (NSData*)TakeScreenshot
{
// Create a graphics context with the target size
// On iOS 4 and later, use UIGraphicsBeginImageContextWithOptions to take the scale into consideration
// On iOS prior to 4, fall back to use UIGraphicsBeginImageContext
CGSize imageSize = [[UIScreen mainScreen]bounds].size;
if (NULL != UIGraphicsBeginImageContextWithOptions)
UIGraphicsBeginImageContextWithOptions(imageSize, NO, 0);
else
UIGraphicsBeginImageContext(imageSize);
CGContextRef context = UIGraphicsGetCurrentContext();
// Iterate over every window from back to front
for (UIWindow *window in [[UIApplication sharedApplication] windows])
{
if (![window respondsToSelector:@selector(screen)] || [window screen] == [UIScreen mainScreen])
{
// -renderInContext: renders in the coordinate space of the layer,
// so we must first apply the layer's geometry to the graphics context
CGContextSaveGState(context);
// Center the context around the window's anchor point
CGContextTranslateCTM(context, [window center].x, [window center].y);
// Apply the window's transform about the anchor point
CGContextConcatCTM(context, [window transform]);
// Offset by the portion of the bounds left of and above the anchor point
CGContextTranslateCTM(context,
-[window bounds].size.width * [[window layer] anchorPoint].x,
-[window bounds].size.height * [[window layer] anchorPoint].y);
// Render the layer hierarchy to the current context
[[window layer] renderInContext:context];
// Restore the context
CGContextRestoreGState(context);
}
}
// Retrieve the screenshot image
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
NSData *imageData = UIImageJPEGRepresentation(image, 100);
UIGraphicsEndImageContext();
return imageData;
}
问题是,我没有看到状态栏。我只有一个没有状态栏的白色区域。如何使用状态栏和其他控件(如tabbar,导航栏等)截取整个屏幕的屏幕截图。
提前致谢!

你正在使用的是official way Apple建议截取屏幕截图。
问题在于此方法会在屏幕上截取您的应用程序输出,而不是整个屏幕。状态栏位于自己的窗口中,无法在您的应用程序中使用。
您应该将自己的状态栏创建为图像并将其添加到项目中,或者只剪切您不需要的屏幕截图。
然后,我建议在论坛中搜索您的问题的可能重复内容,例如:Capturing full screenshot with status bar in iOS programmatically

没有公共方法可以让您截取整个屏幕(即状态栏)。有一个private method虽然UIGetScreenImage
允许您使用实现此功能。但是,由于它是一种私有方法,如果您将其提交到App Store,您的应用将被拒绝。
