[IOS]PDF阅读

Demo地址：http://download.csdn.net/detail/u012881779/9053759

内容：将一个PDF文件分页阅读，页面结构分两部分，覆盖全页的正文部分和页面下方的导航栏部分，并且正文与导航关联了一个对应关系。个人比较懒，就不描述细节了，清晰的PDF文件一般都比较大，若有下载Demo便自己替换reading.pdf文件看看效果。

若没有PDF文件的话，到百度文库里面下载就是，或者把Word转为PDF 。

随便放一段代码在这里呢，没啥好写的

#import "ViewController.h"#import "RoboDocument.h"#import "RoboViewController.h"@interface ViewController ()<RoboViewControllerDelegate>@end@implementation ViewController- (IBAction)PDFReadAction:(id)sender {    NSString *password = @"";    //直接获取的资源路径无法使用    //NSString *filePath = [[NSBundle mainBundle] pathForResource:@"reading" ofType:@"pdf"];    //将资源写入沙盒再获取路径    NSString *filePath;    if([self preparePDF]){        filePath = [self getPDFPath];    }        RoboDocument *document = [RoboDocument withDocumentFilePath:filePath password:password];    if (document != nil) {        RoboViewController *roboViewController = [[RoboViewController alloc] initWithRoboDocument:document small_document:nil];        [roboViewController showDocumentPage:1 fastScroll:NO];        roboViewController.valueDate = [[filePath componentsSeparatedByString:@"/"] lastObject];        roboViewController.delegate = self;        roboViewController.readOrPreview = YES;        [self.navigationController pushViewController:roboViewController animated:YES];    }}- (NSString*)getPDFPath {    NSArray *pathsToDocuments    = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    NSString *documentsDirectory = [pathsToDocuments objectAtIndex:0];    NSString *dbPathInDoc = [documentsDirectory stringByAppendingPathComponent:@"reading.pdf"];    return dbPathInDoc;}- (BOOL)preparePDF{    NSFileManager *fm     = [NSFileManager defaultManager];    NSString *pathBundle  = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"reading.pdf"];    NSString *pathdb      = [self getPDFPath];        if (![fm fileExistsAtPath:pathdb]) {        return [fm copyItemAtPath:pathBundle toPath:pathdb error:nil];    }        return YES;}@end
