非常感谢大家对我的关注！！！！
打开文件的方法：
1.获取文件的沙盒路径path
2.将path路径转化URL
3.用webView显示出来
#import "WebViewController.h"
@interface WebViewController ()<UIWebViewDelegate>
@property(nonatomic, strong)UIWebView *webView;
@end
@implementation WebViewController
- (void)viewDidLoad {
[super viewDidLoad];
_webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height - 64)];
_webView.delegate = self;
_webView.scalesPageToFit = YES;
[self.view addSubview:_webView];
//获取文件路径
NSFileManager *manager = [NSFileManager defaultManager];
NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//获取document文件夹路径
NSString *documents = [array lastObject];
//拼接绝对路径
NSString *documentPath = [documents stringByAppendingPathComponent:@"myReport/file"];
//存数据的具体文件夹
// [manager createDirectoryAtPath:documentPath withIntermediateDirectories:YES attributes:nil error:nil];
//得到文件名
NSArray *fileNameArray = [manager subpathsAtPath:documentPath];
NSString *path = [NSString stringWithFormat:@"%@/%@", documentPath, fileNameArray[0]];
//加载文件
[self loadDocument: path inView:_webView];
}
#parm mark - 加载文件
- (void)loadDocument:(NSString *)documentPath inView:(UIWebView *)webView{
// NSString *path = [[NSBundle mainBundle] pathForResource:documentName ofType:nil];
NSURL *url = [NSURL fileURLWithPath:documentPath];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
