IOS截取部分图片

截取部分图片这么简单:

- (void)loadView { 
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide]; 
    UIImage *image=[UIImage imageNamed:@"1.jpg"]; 
    
    
    CGRect rect = CGRectMake(60, 80, 331, 353);//创建矩形框 
    UIImageView *contentView = [[UIImageView alloc] initWithFrame:rect]; 
    contentView.image=[UIImage imageWithCGImage:CGImageCreateWithImageInRect([image CGImage], rect)]; 
    
    self.view=[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 
    [self.view addSubview:contentView]; 
    
    [image release]; 
}

虽然编写代码的过程是曲折的,但是摸到很多有用的东西,都是以后要用到的。
