Question

CALayer *layer = [_locationBtn layer];
//[layer setMasksToBounds:YES];
[layer setCornerRadius:0.0];
[layer setBorderWidth:1.0];
[layer setBorderColor:[[UIColor grayColor] CGColor]];

[_locationBtn addTarget:self action:@selector(dropDownMtd) forControlEvents:UIControlEventTouchUpInside];
_locationBtn.frame = CGRectMake(20, 170, 280, 40);
[_locationBtn setTitle:@"Select location" forState:UIControlStateNormal];
[self.view addSubview:_locationBtn];

Answer 1

So the solution:
The issue seems to be with the button title color (which I presume was the same color as its background).
So, by setting the title color ( aColor ) different:

[_locationBtn setTitleColor:aColor forState:UIControlStateNormal]
