我必须添加对我的OSX应用程序截图的能力,但是Apple演示只会给我整个屏幕图像,我只想要我的应用程序窗口图像.
我的代码是：
NSInteger displaysIndex = 0;
if(displays != nil)
{
free(displays);
}
CGError err = CGDisplayNoErr;
CGDisplayCount dspCount = 0;
/* How many active displays do we have? */
err = CGGetActiveDisplayList(0,NULL,&dspCount);
/* If we are getting an error here then their won't be much to display. */
if(err != CGDisplayNoErr)
{
return;
}
/* Allocate enough memory to hold all the display IDs we have. */
displays = calloc((size_t)dspCount,sizeof(CGDirectDisplayID));
// Get the list of active displays
err = CGGetActiveDisplayList(dspCount,displays,&dspCount);
/* Make a snapshot image of the current display. */
CGImageRef image = CGDisplayCreateImage(displays[displaysIndex]);
我应该在代码中改变什么,所以我只能收到我的应用程序的窗口？
解决方法
简单.
NSImage *captureImage = [[NSImage alloc] initWithData:[self.view dataWithPDFInsideRect:[self.view bounds]]];
请检查并让我知道.这是捕获的当前活动窗口.
