iPhone – Howe Capture UiView Top UiView

+ (UIImage *) imageWithView:(UIView *)view
{
UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage * img = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
 
return img;
}

- (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;

}

UIImage *tempImageSave=[self captureView];

UIImageWriteToSavedPhotosAlbum(tempImageSave,nil,nil,nil);

NSData *imageData = UIImagePNGRepresentation(tempImageSave);
NSFileManager *fileMan = [NSFileManager defaultManager];
< br />NSString *fileName = [NSString stringWithFormat:@"%d.png",1];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex :0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[fileMan createFileAtPath:pdfFileName contents:imageData attributes:nil];

-(UIImage *)convertViewToImage:(UIView *)viewTemp
{
 UIGraphicsBeginImageContext(viewTemp. bounds.size);
 [viewTemp drawViewHierarchyInRect:viewTemp.bounds afterScreenUpdates:YES];
 UIImage *image = UIGraphicsGetImageFromCurrentImageC ontext();
 UIGraphicsEndImageContext();

 return image;

}

UIImage *tempImageSave = [self convertViewToImage:yourView];

Me There is UIView showing Graph.. Now I need to capture it to UI Image and I searched it with google and got the following code. But if I use it in my code it doesn’t work. Even if I use breakpoint compiler, it can’t reach This. I use it in my UIView. Am I wrong?

+ (UIImage *) imageWithView:(UIView *)view
{
UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage * img = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
 
return img;
}

You can use the following methods to take a screenshot of any view of the iPhone app or the entire screen

- (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;

}

and call it a bellow…

UIImage *tempImageSave=[self captureView];

You can also save this image with the ripple line of this album..

UIImageWriteToSavedPh otosAlbum(tempImageSave,nil,nil,nil);

You can also use the corrugated line of this document directory to save this image.

NSData *imageData = UIImagePNGRepresentation(tempImageSave);
NSFileManager *fileMan = [NSFileManager defaultManager];

NSString *fileName = [NSString stringWithFormat:@"%d.png",1];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[fileMan createFileAtPath: pdfFileName contents:imageData attributes:nil];

If the view contains layer images or some graphics-related data, use the following methods.

-( UIImage *)convertViewToImage:(UIView *)viewTemp
{
 UIGraphicsBeginImageContext(viewTemp.bounds.size);
 [viewTemp drawViewHierarchyInRect:viewTemp.bounds afterScreenUpdates:YES];
 UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
 UIGraphicsEndImageContext();

 retu rn image;

}

And use the following method.

UIImage *tempImageSave = [self convertViewToImage:yourView];< /pre> 

I hope this helps you.
