Another UIButton background color issue

Question

Yet another simple issue with changing the background color of a UIButton. So I have figured after searching a bit that a common way is to either create an image or subview.

I have created a button in storyboard and connected it to an outlet. In my VC class I have the following

.h

@property (nonatomic, readwrite, strong) IBOutlet UIButton *uiLoginButton;

.m

- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"%s and frame rect %@", __PRETTY_FUNCTION__, self.uiLoginButton); //here uiloginbutton does not have any size!

CGRect buttonRect = CGRectMake(50, 50, 100.0, 100.0);

self.uiLoginButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.uiLoginButton.frame = buttonRect;
self.uiLoginButton.backgroundColor = [UIColor redColor];
NSLog(@"%s and frame rect %@", __PRETTY_FUNCTION__, self.uiLoginButton);    
}

No I have set the values in CGRectMake randomly because the IBOutlet button's frame is 0. How come?

What is the correct way to actually change the button's color?

Answer 1

If you are creating a button in nib you can change all the properties via nib itself. Like this

OR

If you want to do it codewise since you are adding it via nib points to note

• No need for an initialization.since it is a property from IB.
• Just directly provide frame via IB or in code via -setFrame: method
• To set color, you can use -setBackgroundcolor: method

So my .h

@property (nonatomic,strong) IBOutlet UIButton *uiLoginButton;

.m

[self.uiLoginButton setFrame:buttonRect];
[self.uiLoginButton setBackgroundColor:[UIColor redColor]];
