ios - Blurry UILabel when added programmatically

Question

I am adding a UILabel to a view meant for loading purposes. However, it gets blurry after I added it. The weird thing is that I just about the same code for an loading view which is loaded ontop of an UITableViewController and it works great there. Yet, this one on top of an UIViewController is blurry.

This is my code:

float x = (self.view.frame.size.width-20)/2;
float y = (self.view.frame.size.height-70)/2;

// Add loading and sub text
UILabel *loadingText = [[UILabel alloc] initWithFrame:CGRectMake(10, round(y+30), round(self.view.frame.size.width-20), 21)];
[loadingText setTextAlignment:UITextAlignmentCenter];
[loadingText setNumberOfLines:0];
[loadingText setFont:[UIFont systemFontOfSize:17]];
[loadingText setText:NSLocalizedString(@"Please wait...
We are processing your request", @"LoadingPage")];
[loadingText sizeToFit];
[loadingText setBackgroundColor:[UIColor clearColor]];
[loadingText setCenter:self.view.center];
[loadingText setTag:2];

[view addSubview:loadingText];

Answer 1

Your label is blurry because the frame is using floating numbers.

To force integers value for your frame just do :

[loadingText setFrame:CGRectIntegral(loadingText.frame)];

You could also cast all your values composing your frame to int, but CGRectIntegral does all the job for you.
