How to get requested image size for iOS8 PhotoKit?

Question

I am using the code below for fetching an image:

[[PHImageManager defaultManager] requestImageForAsset:asset 
targetSize:CGSizeMake(800, 600) 
contentMode:PHImageContentModeAspectFill 
options:options 
resultHandler:^(UIImage *result, NSDictionary *info) {
    NSLog(@"size:%@",NSStringFromCGSize(result.size));                
}];

I'm requesting an image size of 800 x 600, but I'm getting an image size of 45 x 60, which is very poor-quality.

How can i get the requested image size using PhotoKit?

Answer 1

I was able to get image of size 800*600 using below code:

PHImageRequestOptions* options = [[[PHImageRequestOptions alloc] init] autorelease];
options.version = PHImageRequestOptionsVersionCurrent;
options.deliveryMode =  PHImageRequestOptionsDeliveryModeHighQualityFormat;
options.resizeMode = PHImageRequestOptionsResizeModeExact;

[PHImageManager defaultManager]
requestImageForAsset:(PHAsset *)asset
targetSize:CGSizeMake(800, 600)
contentMode:PHImageContentModeAspectFit
options:options
resultHandler:^(UIImage *result, NSDictionary *info) {
   NSLog(@"Image size:%@",NSStringFromCGSize(result.size));
}];

And if you want to get full size image you can use PHImageManagerMaximumSize as targetSize.
