Question

how to rotate uibutton like this in iphone sdk.....

Solution 1

If you have an IBOutlet Object.

theButton.transform = CGAffineTransformMakeRotation(M_PI / -4);

If you want to create run time button on view.

- (void)viewDidLoad {
    [super viewDidLoad];
    UIButton *btn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btn setFrame:CGRectMake(100, 100, 200, 44)];
    btn.transform=CGAffineTransformMakeRotation(M_PI / -4);
    [btn setTitle:@"RakeshBhatt" forState:UIControlStateNormal];
    [self.view addSubview:btn];
}

Solution 2

theButton.transform = CGAffineTransformMakeRotation(-M_PI / 4);

(Note: π/4 = 45°.)

Solution 3

rotate to degree

#define degreesToRadians(x) (M_PI * (x) / 180.0)

then use / 90 is the degree:

button.transform=CGAffineTransformMakeRotation(degreesToRadians(90));

Solution 4

The Swift version:

button.transform = CGAffineTransformMakeRotation(CGFloat(-M_PI_4))
