set cornerRadius and setbackgroundimage to UIButton

Question

I am trying to set cornerRadius of UIButton but I dont know how to do it.

If I do like this:

button.layer.cornerRadius = 5;

works well, if I do like this :

button.layer.cornerRadius = 5;
[button setBackgroundColor:[UIColor colorWithPatternImage:radialGradient]];

the corners are not rounded.

I know I could solve this whit

 [button.layer setMasksToBounds:YES];

but I specifically looking for different solution, because I add some arrows to the button and if I set mask to bounds the arrow are masked.

EDIT :

radialGradient is made whit func

+ (UIImage *)getRadialGradientImage:(CGSize)size centre:(CGPoint)centre radius:(float)radius startColor:(UIColor *)startColor endColor:(UIColor *)endColor{

// Initialise
UIGraphicsBeginImageContextWithOptions(size, YES, 1);

// Create the gradient's colours
size_t num_locations = 2;
CGFloat locations[2] = { 0.0, 1.0 };

const CGFloat *component_first = CGColorGetComponents([startColor CGColor]);

CGFloat red1 = component_first[0];
CGFloat green1 = component_first[1];
CGFloat blue1 = component_first[2];

const CGFloat *component_second = CGColorGetComponents([endColor CGColor]);
CGFloat red2 = component_second[0];
CGFloat green2 = component_second[1];
CGFloat blue2 = component_second[2];

const CGFloat components[8] = { red1,green1,blue1,1,red2,green2,blue2,1}; // End color

CGColorSpaceRef myColorspace = CGColorSpaceCreateDeviceRGB();
CGGradientRef myGradient = CGGradientCreateWithColorComponents (myColorspace, components, locations, num_locations);

// Normalise the 0-1 ranged inputs to the width of the image
CGPoint myCentrePoint = CGPointMake(centre.x * size.width, centre.y * size.height);
float myRadius = MIN(size.width, size.height) * radius;

// Draw it!
CGContextDrawRadialGradient (UIGraphicsGetCurrentContext(), myGradient, myCentrePoint,
                             0, myCentrePoint, myRadius,
                             kCGGradientDrawsAfterEndLocation);

// Grab it as an autoreleased image
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

// Clean up
CGColorSpaceRelease(myColorspace); // Necessary?
CGGradientRelease(myGradient); // Necessary?
UIGraphicsEndImageContext(); // Clean up
return image;
}

Solution 1

Here is how I would create a button through code and set its background color.

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(100, 100, 100,50);
[btn setTitle:@"Hello" forState:UIControlStateNormal];
[btn setBackgroundColor:[UIColor colorWithRed:128.0/255.0f green:0.0/255.0f  blue:0.0/255.0f alpha:0.7]];
btn.frame = CGRectMake(100.0, 100.0, 120.0, 50.0);//width and height should be same  value
btn.clipsToBounds = YES;

btn.layer.cornerRadius = 20;//half of the width
btn.layer.borderColor=[UIColor redColor].CGColor;
btn.layer.borderWidth=2.0f;

[self.view addSubview:btn];

Below is the image of the button that is related with the above code

You can always play around with code and create the colors that you need for background and border. Hope this would help you out.

Solution 2

btn.clipsToBounds = YES; 

i Just added this and it worked for me. I was actually able to set corner radius to UIButton with setting an image to that particular UIButton.

Solution 3

You can also have:

btn.clipsToBounds = true;

Solution 4

If you are using the image in your button background then you need to set clipsTobounds to true.

button.layer.cornerRadius = 10 
button.clipsToBounds = true

Solution 5

//create button like this

     UIButton *cancel=[[UIButton alloc]initWithFrame:CGRectMake(9, 9,35,35)];
    cancel.backgroundColor=[UIColor  colorWithPatternImage:[UIImage imageNamed:@"BackX.png"]];
[cancel setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    [cancel.layer setBorderColor: [[UIColor blackColor] CGColor]];
    [cancel.layer setBorderWidth: 1.0];
    cancel.contentMode=UIViewContentModeScaleAspectFill;
    cancel.clipsToBounds=YES;
    cancel.layer.cornerRadius=8.0;
    [cancel addTarget:self action:@selector(cancelbtnclk1:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:cancel];

Before that add QuartzCore Framework and import QuartzCore/CoreAnimation.h in your .h file.

hope it will helps you..

Hi, thanks for reply, but I specifically dont want clipToBounds.

[Admin]

Yes, but then it is not cornered :D

[JAL]

Be careful, YES/NO should be used with Objective-C while true/false may be used for Swift.

[Luke]

@JAL You can also use true/TRUE and false/FALSE in Objective-C, along with YES and NO.

[JAL]

It's better to use YES/NO with the Objective-C BOOL type, since true/false map to the C bool type.

That is awesome! Now I know that bounds include border radius.
