问题描述

我在UIWebView中显示本地pdf文件,但它在路径中显示异常,这是我的代码

I am display local pdf file in UIWebView but it shows exception in path here is my code

     NSString*fileName=content_Source;
     NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:@"pdf"];
     NSURL *url = [NSURL fileURLWithPath:path];
     NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webView setScalesPageToFit:YES];
    [webView loadRequest:request]

推荐答案

首先验证该字符串并分配给URL,例如波纹管.

first validate that string and the assign to URL like bellow..

   NSString *strURLPath = [self trimString: path];
   NSURL *url = [NSURL fileURLWithPath:strURLPath];

使用我的波纹管方法...

use my bellow method...

-(NSString*) trimString:(NSString *)theString {
    if (theString != [NSNull null])
        theString = [theString stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];
    return theString;
}
