iphone - Taking time to load the image from URL to UIImageview

Question

I am using this code for displaying the image from URL to UIImageview

UIImageView *myview=[[UIImageView alloc]init];

myview.frame = CGRectMake(50, 50, 320, 480);

NSURL *imgURL=[[NSURL alloc]initWithString:@"http://soccerlens.com/files/2011/03/chelsea-1112-home.png"];

NSData *imgdata=[[NSData alloc]initWithContentsOfURL:imgURL];

UIImage *image=[[UIImage alloc]initWithData:imgdata];

myview.image=image;

[self.view addSubview:myview];

But the problem is that its taking too long time to display the image in imageview.

Please help me...

Is there any method to fast the process...

Answer 1

Instead of dispatch_async, Use SDWebImage for caching the images.

This is best I have seen...

The problem of dispatch_async is that if you lost focus from image, it will load again. However SDWebImage, Caches the image and it wont reload again.
