ios – 捕获UIView并另存为图像

1) Original Image Link :-

2) After Capture the image Link :-

代码： –

UIGraphicsBeginImageContext(vIEwImage.frame.size);    [vIEwImage.layer renderInContext:UIGraphicsGetCurrentContext()];    UIImage *vwImage = UIGraphicsGetimageFromCurrentimageContext();    UIGraphicsEndImageContext();    NSData *data=UIImagePNGRepresentation(vwImage);    NSArray *paths = NSSearchPathForDirectorIEsInDomains(NSdocumentDirectory,NSUserDomainMask,YES);    Nsstring *documentsDirectory = [paths objectAtIndex:0];   // Nsstring *imgname = [Nsstring stringWithFormat:imagename];    Nsstring *strPath = [documentsDirectory stringByAppendingPathComponent:imagename];    [data writetofile:strPath atomically:YES];

解决方法 您可以拍摄任何UIVIEw的屏幕截图或捕获任何UIVIEw,并将其保存为具有以下代码的图像.

- (UIImage *)captureVIEw {    //hIDe controls if needed    CGRect rect = [self.vIEw bounds];    UIGraphicsBeginImageContext(rect.size);    CGContextRef context = UIGraphicsGetCurrentContext();    [self.vIEw.layer renderInContext:context];       UIImage *img = UIGraphicsGetimageFromCurrentimageContext();    UIGraphicsEndImageContext();    return img;}
