Memory leak in UIButton setFont method

Question

Hi,
Hope you all doing well, I am getting a memory leak while setting the font of UIButton. This is the code which I am using to set the font,
[MyBtn.titleLabel setFont:[UIFont boldSystemFontOfSize:12]];
whereas MyBtn is connected to IBOoutlet and I am not allocating memory to it.
I don't see any thing wrong in the code. Hopefully someone will help me out, I will be really thankful.

In instrument the responsible library is UIKit and UILabel is the leaked object so I am also not sure whether instrument is pointing the right line or not.
Below is the function in which I am getting the leak,
- (void) LayoutUI
[bgImageView setImage:[UIImage imageNamed:@"bgImage.png"]];
[topImageHeaderView setImage:[UIImage imageNamed:@"headerImage.png"]];
[logoImageView setImage:[UIImage imageNamed:@"logo.png"]];
[HeaderImageView setImage:[UIImage imageNamed:@"headerImageView.png"]];
[BackBtn setTitle:@"Back" forState:UIControlStateNormal];
[BackBtn.titleLabel setFont:[UIFont boldSystemFontOfSize:12]];
[BackBtn setBackgroundImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
//below is the Leaked line of code
[BackBtn.titleLabel setTextColor:[UIColor colorWithRed:(50.0/256.0) green:(100.0/256.0) blue:(200.0/256.0) alpha:1]];
[headerLbl setText:@"Header"];
//below two lines are leaked
[headerLbl setFont:[UIFont boldSystemFontOfSize:12]];
[headerLbl setTextColor:[UIColor colorWithRed:(50.0/256.0) green:(100.0/256.0) blue:(200.0/256.0) alpha:1]];
hopefully this will show a picture of what I am doing in my code.
One more thing all these UIlabels and UIImage are connected to IBOoutlet so I am not allocating memory to any of them but though I have tried to dealloc all of them in dealloc method but it didn't help me out.
