Objective C, Can't load an image from data returned by ASIHTTP request

- (vo开发者_如何学Goid)requestFinished:(ASIHTTPRequest *)request
{
    // Use when fetching text data
    NSData *data = [NSData dataWithData:[request responseData]];
    NSData *responseData = [request responseData];


    UIImage *img = [[UIImage alloc ]imageWithData:data];//it blows up here
    self.q.image = img;

    [img release];
    self.request = nil;
    [delegate imageDidLoad:self.indexPathInTableView];

}

I am downloading an image data using ASIHTTP request and it worked fine. But If I try to create an image using the data from ASIHTTP request then it blows up..What is the problem? Thanks in advance...

Its because you are using imageWithData: to create your image, you should use initWithData: or just [UIImage imageWithData:data] instead of alloc'ing first.

Your code doesn't work because imageWithData: is a static method on UIImage that generates an autoreleased UIImage instance. Because it is a static method, not an instance method, it isn't a recognised selector on the UIImage instance you get when you call [UIImage alloc]

as the error says the it's an unrecognized selector.

you should call - (id)initWithData:(NSData *)data.

[[UIImage alloc] initWithData:data];

or

[UIImage imageWithData:data];
