使用

标准情况

HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
	[self.navigationController.view addSubview:HUD];
	
	HUD.delegate = self;
	HUD.labelText = @"Loading";
	HUD.detailsLabelText = @"updating data";
	HUD.square = YES;
	
	[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];

- (void)myTask {
	// Do something usefull in here instead of sleeping ...
	sleep(3);
}	
	

带进度条的情况

HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
	[self.navigationController.view addSubview:HUD];
	
	// Set determinate mode
	HUD.mode = MBProgressHUDModeAnnularDeterminate;
	
	HUD.delegate = self;
	HUD.labelText = @"Loading";
	
	// myProgressTask uses the HUD instance to update progress
	[HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];
	

- (void)myProgressTask {
	// This just increases the progress indicator in a loop
	float progress = 0.0f;
	while (progress < 1.0f) {
		progress += 0.01f;
		HUD.progress = progress;
		usleep(50000);
	}
}
