Question

I am trying to increment progress bar and show percentage on a label. However, both remains without changes when “incrementaProgres” function is called. IBOutlets are properly linked on xib and also tested that, when function is called, variables have proper value. Thanks

from delegate:

loadingViewController *theInstanceP = [[loadingViewController alloc] init];
[theInstanceP performSelectorOnMainThread:@selector(incrementaProgres:) withObject:[NSNumber numberWithFloat:0.15] waitUntilDone:YES];

loadingView class:

- (void)viewDidLoad
{
    [super viewDidLoad];

    [spinner startAnimating];
    [progress setProgress:0.0];
}

- (void)incrementaProgres: (CGFloat)increment{

    [progress setProgress:(progresInc + increment)];
    carrega.text = [NSString stringWithFormat: @"%f", (progresInc + increment)];

}

Progress bar’s progress value is between 0.0 and 1.0, your code sets it in the increments of 15.0, which is out of range. Your increment should be 0.15, not 15.0.
