having a problem adding multiple ImageViews to my view. I have an array of images and what to cycle through them and add to my view. This snippet adds an image to view, but with no frame!
- (void)cycleImages:(NSArray *)images {
//create an image view
int fromLeft = 5;
int profilesCount = [images count] - 1;
for(int n = 0; n <= profilesCount; n++){
//add image view to view
[self.view addSubview:[[[UIImageView alloc] initWithFrame:CGRectMake(5, fromLeft, 48, 48)] initWithImage:[[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[images objectAtIndex:n]]]]]];
fromLeft = fromLeft + 53;
NSLog(@"%d", fromLeft);
}
}
Thanks for your help!

Its hard to read such code and you have mem leaks. Please, try this.
- (void)cycleImages:(NSArray *)images
{
int fromLeft = 5;
NSURL* url = nil;
UIImage* img = nil;
UIImageView* imgView = nil;
NSData* imgData = nil;
for (NSString* imgURLStr in images)//Using enumeration much more easy and in ObjC style
{
//Put breakpoint here and check all varibles initialized coorecly step by step
url = [NSURL URLWithString:imgURLStr];
imgData = [NSData dataWithContentsOfURL:url];
img = [[UIImage alloc] initWithData:imgData];
imgView = [[UIImageView alloc] initWithImage:img];
imgView.frame = CGRectMake(5, fromLeft, 48, 48);
[self.view addSubView:imgView];
fromLeft = fromLeft + 53;
NSLog(@"%d", fromLeft);
//Clean up
[img release];
[imgView release];
}
}
Thanks!
