这是我的活动之一，我使用 NSURL 连接点击了一个 url，然后解析这个数据并以字节码获取 JSON 数据这个数据，如
NSString *ptr= { 82, 111, 111, 116, 32, 50, 32, 48, 32, 82, 10, 47, 83, 105, 122, 101, 32, 51, 50, 10, 47, 73, 110, 102, 111, 32, 49, 32, 48, 32, 82, 10, 62, 62、10、115、116、97、114、116、120、114、101、102、10、49、52、51、52、50、55、10、37、37、69、79、70、10。 ........ETC }
我在 NSString 中得到了这个，之后
NSMutableArray *bytes=[[NSMutableArray alloc]init];
[bytes addObject:ptr];
NSMutableData *data = [[NSMutableData alloc] initWithCapacity:bytes.count];
NSLog(@"file %@",data);
for (NSNumber *byteVal in bytes)
{
Byte b = (Byte)(byteVal.intValue);
[data appendBytes:&b length:1];
}
NSArray *docDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [docDirectories objectAtIndex:0];
NSString *fileName = [docDirectory stringByAppendingPathComponent:@"abcd.pdf"];
NSLog(@"file %@",fileName);
[data writeToFile:fileName atomically:NO];
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:@"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:@"abcd.pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:filePath];
NSURLRequest *requestFile = [NSURLRequest requestWithURL:targetURL];
NSLog(@"request path %@",requestFile);
这是输出。它会创建 pdf，但我不明白如何打开和查看生成的 pdf 文件。
文件 /Users/rahulsharma/Library/Application Support/iPhone Simulator/6.1/Applications/CD29ED82-8039-411F-8BBA-2784E5445EDE/Documents/abcd.pdf

请帮助我解决如何获取pdf的问题。
