UIButton *testButton = [UIButton buttonWithType:UIButtonTypeSystem];

    [testButton setFrame:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/2, 100, 100)];

    [testButton setTitle:@"擷取螢幕尺寸" forState:UIControlStateNormal];

   

    

    [testButton.layer setMasksToBounds:YES];//設定按鈕的圓角半徑不會被遮擋

    [testButton.layer setCornerRadius:10];

    [testButton.layer setBorderWidth:2];//設定邊界的寬度

    

    //設定按鈕的邊界顏色

    CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB();

    CGColorRef color = CGColorCreate(colorSpaceRef, (CGFloat[]){1,0,0,1});

    [testButton.layer setBorderColor:color];
