Question

I am loading a file and would like to show the progress in a UIProgressView. I can set the initial with:

[loadingProgressView setProgress: 0.00];

..in viewDidLoad this works perfectly.

The only thing I want to do then is to add 0.1 to the bar each loop but it does not update:

 while (eOF != 99999) {

    ...

    [loadingProgressView setProgress:loadingProgressView.progress + 0.10];

 }

I have checked around but not really found anything around just updating the bar each time I loop.

Anyone that can share some advice around this?

—UPDATE—

tried this without success:

while (eOF != 99999) {

    ...

    [loadingProgressView setProgress:loadingProgressView.progress + 0.10];
    [[NSRunLoop currentRunLoop] runUntilDate:[NSDate date]];

 }

MY FINAL SOLUTION

First, if this is the wrong way of closing this thread i do apologize!

After a lot of testing and investigation i finally did as follows to display my UIProgressView:

while (eOF != 99999) {

    ...

    [NSThread sleepForTimeInterval: 0.01];
    [self performSelectorOnMainThread: @selector(makeMyProgressBarMoving) withObject: nil waitUntilDone: NO];

 }



-(void)makeMyProgressBarMoving {
    float actual = [loadingProgressView progress];
    loadingProgressView.progress = actual + receivedData;
} 

…and now finally it works perfectly 🙂

However, thanks for all help, i learned a lot out of this.
