Adding a UIImage to UIImageView programmatically

In .h file I declare this;

IBOutlet UIImageView *image;

In .m file;

UIImage *image1 = [UIImage imageName:@"http://image.com/image.jpg"];
image = [[UIImageView alloc] initWithImage:image1];
image.frame = CGRectMake(0,0, 50,50);
[self.view addSubView:image];

and I connected the UIImageView from the Interface builder. But I need to do this Only by code (without using the Interface Builder). Can someone help me modify the code so that I could do this only by code?

and i connected the UIImageView from the Interface builder

That was a mistake. If you do that, the image view pointed to by your image instance variable will be the wrong one - the one in the nib. You want it to be the one that you created in code.

So, make no connection from Interface Builder; in fact, delete the image view from Interface Builder so you don't confuse yourself. Make sure your instance variable is also a property:

@property (nonatomic, retain) UIImageView* image;

Synthesize the property:

@synthesize image;

Now your code will work:

UIImage *image1 = [UIImage imageName:@"http://image.com/image.jpg"];
self.image = [[UIImageView alloc] initWithImage:image1];
// no memory management needed if you're using ARC
[self.view addSubview:self.image];

You will need to play with the frame until the location is correct. Note that the frame will automatically be the same size as the image, by default.

I THINK you have some problem in displaying a remote image in uiimageview so i thing u should do that fashion.

NSData *receivedData = [[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://image.com/image.jpg"]] retain];
UIImage *image = [[UIImage alloc] initWithData:receivedData] ;

UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(0,0, 50,50);
[self.view addSubView:image];

[image release];
[imageView release];

UIImage *someImage = [UIImage imageName:@"http://image.com/image.jpg"];
UIImageView* imageView = [[UIImageView alloc] initWithImage:someImage];
[self.view addSubView:imageView];

you dont need to connect. This code will work without connecting. Leave IBOutlet out.
