如何实现聊天软件的图片显示的剪裁后的气泡呢
Objective-C:
- (void)viewDidLoad { [super viewDidLoad]; UIImageView *ImageView01 = [[UIImageView alloc] init]; [ImageView01 setFrame:CGRectMake(90, 190, 120, 180)]; [ImageView01 setImage:[UIImage imageNamed:@"style.jpg"]]; [self.view addSubview:ImageView01]; UIImage *bubble = [UIImage imageNamed:@"icon_chat_right_bg"]; UIImageView *ImageView = [[UIImageView alloc] init]; [ImageView setFrame:ImageView01.frame]; [ImageView setImage:[bubble stretchableImageWithLeftCapWidth:15 topCapHeight:15]]; CALayer *layer = ImageView.layer; layer.frame = (CGRect){{0,0},ImageView.layer.frame.size}; ImageView01.layer.mask = layer; [ImageView01 setNeedsDisplay]; }
Swift:
override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. var imageview01 = UIImageView(frame: CGRectMake(90, 190, 120, 180)) imageview01.image = UIImage(named: "style.jpg") self.view.addSubview(imageview01) var imageview02 = UIImageView(frame: imageview01.frame) imageview02.image = UIImage(named: "icon_chat_right_bg")?.stretchableImageWithLeftCapWidth(15, topCapHeight: 15) var layer = imageview02.layer layer.frame = CGRect(origin: CGPointZero,size: imageview02.layer.frame.size) imageview01.layer.mask = layer }
