UIScrollView的常见属性
1.CGPoint contentOffset:用来表示UIScrollView滚动的位置
2.CGSize contentSize:用来表示UIScrollView内容的尺寸,滚动范围
3.UIEdgeInsets contentInset:能够在UIScrollView的4周增加额外的滚动区域
#import "ViewController.h" @interface ViewController () @property (weak, nonatomic) IBOutlet UIScrollView *scrollView; @property (weak, nonatomic) IBOutlet UIImageView *mView; - (IBAction)scroll; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.scrollView.contentSize = self.mView.frame.size; // 总体内容的范围(滚动范围) self.scrollView.contentInset = UIEdgeInsetsMake(200, 400, 800, 1600);//设置内边距 }
-(IBAction)scroll{ CGPoint offset = self.scrollView.contentOffset; offset.x+=10; offset.y+=10; [self.scrollView setContentOffset:offset animated:YES]; } @end
