ipad subview not loading before code is executing - iphone

Question

I have a command that should be loading a subview before a particular piece of time intensive code executes. However the command runs, the timely code executes and then the subview shows up. Is there anything I can do to fix this problem?
progressViewController = [[ProgressView alloc] initWithNibName:#"ProgressView" bundle:[NSBundle mainBundle]];
[self.view addSubview:[progressViewController view]];
NSString *name=#"guy";
NSString *encodedName =[[NSString alloc] init];
int asci;
for(int i=0; i < [name length]; i++)
{
//NSLog(#"1");
asci = [name characterAtIndex:i];
NSString *str = [NSString stringWithFormat:#"%d,", asci];
encodedName =[encodedName stringByAppendingFormat: str];
}
NSString *urlString = [NSString stringWithFormat:#"someurl.com"];
NSURL *theUrl = [[NSURL alloc] initWithString:urlString];
NSString *result=[NSString stringWithContentsOfURL:theUrl];
result = [result substringFromIndex:61];
result = [result substringToIndex:[result length] - 20];
NSLog(result);
outLab.text=result;
[[progressViewController view] removeFromSuperview];

Answer 1

1) try
[self.view setNeedsUpdating]
after adding the subview
2)
try splitting the time intensive into another thread....
- (void) f
{
// executed in main UI thread
progressViewController = [[ProgressView alloc] initWithNibName:#"ProgressView" bundle:[NSBundle mainBundle]];
[self.view addSubview:[progressViewController view]];
[NSThread detachNewThreadSelector:#selector(doCompute) toTarget:self
withObject:nil];
}
- (void) doCompute
{
// in a different thread....so we need a autoreleasepool
NSAutoreleasePool *autoreleasepool = [[NSAutoreleasePool alloc] init];
// do your computation here...
[self performSelectorOnMainThread:#selector(taskComplete:)
withObject:result waitUntilDone:NO];
[autoreleasepool release];
}
- (void) taskComplete
{
// executed in UI thread
[self.progressView removeFromSuperView];
}

You could subclass the view and then use the viewDidLoad function to execute your long running code.
