1、想要使用此功能首先要在工程内加入框架
QuickLook.framework
2、在你需要展示的界面加入头文件
#import <QuickLook/QuickLook.h>
3、实例化
QLPreviewController *myQlPreViewController = [[QLPreviewController alloc]init];
myQlPreViewController.delegate =self;
myQlPreViewController.dataSource =self;
[myQlPreViewController setCurrentPreviewItemIndex:0];
//此处可以带导航栏跳转、也可以不带导航栏跳转、也可以拿到View进行Add
[self.navigationController pushViewController:myQlPreViewController animated:YES];
4、代理方法
#pragma mark - QLPreviewController代理
- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller
{
return 1;
}
- (id<QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index
{
NSString* path = [[NSBundle mainBundle] pathForResource:arr[IndeX] ofType:nil];
return [NSURL fileURLWithPath:path];
}
- (void)previewControllerDidDismiss:(QLPreviewController *)controller
{
NSLog(@"预览界面已经消失");
}
//文件内部链接点击不进行外部跳转
- (BOOL)previewController:(QLPreviewController *)controller shouldOpenURL:(NSURL *)url forPreviewItem:(id <QLPreviewItem>)item
{
return NO;
}
