how to set cornerRadius for only top-left and top-right corner of a UIView

Here's a method - I'm sure it could be shortened.... :D

-(UIView *)roundCornersOnView:(UIView *)view onTopLeft:(BOOL)tl topRight:(BOOL)tr bottomLeft:(BOOL)bl bottomRight:(BOOL)br radius:(float)radius {

UIRectCorner corner; //holds the corner


//Determine which corner(s) should be changed
if (tl) {
    corner = UIRectCornerTopLeft;
}
if (tr) {
    corner = UIRectCornerTopRight;
}
if (bl) {
    corner = UIRectCornerBottomLeft;
}
if (br) {
    corner = UIRectCornerBottomRight;
}
if (tl && tr) { //top
    corner = UIRectCornerTopRight | UIRectCornerTopLeft;
}
if (bl && br) { //bottom
    corner = UIRectCornerBottomLeft | UIRectCornerBottomRight;
}
if (tl && bl) { //left
    corner = UIRectCornerTopLeft | UIRectCornerBottomLeft;
}
if (tr && br) { //right
    corner = UIRectCornerTopRight | UIRectCornerBottomRight;
}

if (tl & tr & bl & br) {
    corner = UIRectCornerAllCorners; 
}

UIView *roundedView = view;
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:roundedView.bounds byRoundingCorners:corner cornerRadii:CGSizeMake(radius, radius)];
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = roundedView.bounds;
maskLayer.path = maskPath.CGPath;
roundedView.layer.mask = maskLayer;

return roundedView;
}

    UIButton *openInMaps = [UIButton new];

    [openInMaps setFrame:CGRectMake(15, 135, 114, 70)];
    openInMaps = (UIButton *)[self roundCornersOnView:openInMaps onTopLeft:NO topRight:NO bottomLeft:YES bottomRight:NO radius:5.0];

TSMessages

This framework provides an easy to use class to show little notification views on the top of the screen. (à la Tweetbot).

The notification moves from the top of the screen underneath the navigation bar and stays there for a few seconds, depending on the length of the displayed text. To dismiss a notification before the time runs out, the user can swipe it to the top or just tap it.

There are 4 different types already set up for you: Success, Error, Warning, Message (take a look at the screenshots)

It is very easy to add new notification types with a different design. Add the new type to the notificationType enum, add the needed design properties to the configuration file and set the name of the theme (used in the config file and images) in TSMessagesView.m inside the switch case.

Take a look at the Example project to see how to use this library. You have to open the workspace, not the project file, since the Example project uses cocoapods.
