                                                self.downloadButton.initialTitle = @”Download”;

self.downloadButton.completeTitle = @”Open”;
// Add a target (like a regular button)

[self.downloadButton addTarget:self action:@selector(downloadButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
-(void)downloadButtonPressed:(id)sender {

// Update the button’s state based on your downloading item’s state

if(!self.isDownloading && !self.isDownloaded) {

[self.downloadButton startProgressing];

[self downloadItem];

} else if(self.isDownloaded) {

[self openItem];

} else {

[self cancelDownloadingItem];

[self.downloadButton setProgress:0 animated:YES withCompletion:^{

[self.downloadButton reset];

}];
