保存照片到系统相册
保存照片到系统相册这个功能很多社交类的APP都有的,今天我们简单讲解一下,如何将图片保存到系统相册(Photo Album)。
1.创建UIImageView
创建UIImageView是为了将照片展示出来,我们是要把UIImage保存到系统相册(Photo Album):
复制代码#define SCREEN [UIScreen mainScreen].bounds.size
self.image = [UIImage imageNamed:@"iOSDevTip"];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake((SCREEN.width - 300) / 2, 70, 300, 150)];
imageView.image = self.image;
[self.view addSubview:imageView];
2.创建UIButton
创建UIButton并绑定actionClick:事件:
复制代码UIButton *button = [[UIButton alloc] init];
button.frame = CGRectMake( 100, 300, SCREEN.width - 200, 40);
[button addTarget:self action:@selector(actionClick:) forControlEvents:UIControlEventTouchUpInside];
[button setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[button setBackgroundColor:[UIColor orangeColor]];
[button setTitle:@"SavePhoto" forState:UIControlStateNormal];
[self.view addSubview:button];
- (void)actionClick:(UIButton *)button
{
}
3.保存照片到系统相册(Photo Album)
