首先我在UI
ImageView上添加UILable,然后在屏幕截图UIView之后,图像不正确地捕获UIView Frame我也附加了图像url.
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;
}
