I bring the issue forward which I face. I am creating a UITextField programmatically as below.
UItextField *mobileNumberField = [[UITextField alloc] initWithFrame:CGRectMake(10, 195, 300, 41)];
mobileNumberField.delegate = self;
mobileNumberField.borderStyle = UITextBorderStyleRoundedRect;
[mobileNumberField.layer setCornerRadius:14.0f];
mobileNumberField.placeholder = @"Mobile Number";
[self.paymentsHomeView addSubview:mobileNumberField];
The output is the attached image.

I dont know why is it breaking at the corners. Help me to fix my text field like the image attached below.

Just remove this line…
and add this code also..
