一、从系统“文件”APP选择文件上传
#import "ViewController.h"
@interface ViewController () <UIDocumentPickerDelegate>
@property (nonatomic, strong) UIDocumentPickerViewController *documentPickerVC;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
}
- (IBAction)tapSelectFileAction:(id)sender {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.35 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[self presentViewController:self.documentPickerVC animated:YES completion:nil];
});
}

float version = [[[UIDevice currentDevice] systemVersion] floatValue];
if (version >= 11) {
} else {
[MBProgressHUD showError:@"下载文件要求手机系统版本在11.0以上"];
return;
}
/**
/// 保存网络文件到沙盒一
NSURLRequest *req = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:filePath]];
NSData *fileData = [NSURLConnection sendSynchronousRequest:req returningResponse:nil error:nil];

NSFileManager *fm = [NSFileManager defaultManager];
NSString *fullPath = [self getNativeFilePath:[filePath componentsSeparatedByString:@"/"].lastObject];
BOOL downResult = [fm createFileAtPath:fullPath contents:fileData attributes:nil];
*/

// 设置代理
documentPickerVC.delegate = self;
// 设置模态弹出方式
documentPickerVC.modalPresentationStyle = UIModalPresentationFormSheet;
[self.navigationController presentViewController:documentPickerVC animated:YES completion:nil];
}
}
// 获得文件沙盒地址

BOOL isDir = NO;
NSMutableArray *theArr = [[filePath componentsSeparatedByString:@"/"] mutableCopy];
[theArr removeLastObject];

BOOL existed = [fileManager fileExistsAtPath:thePath isDirectory:&isDir];
if ( !(isDir == YES && existed == YES) ) { // 如果文件夹不存在
