来自本地文件 URL 的 iPhone-NSData

小开

最佳答案

// Given some file path URL: NSURL *pathURL
// Note: [pathURL isFileURL] must return YES
NSString *path = [pathURL path];
NSData *data = [[NSFileManager defaultManager] contentsAtPath:path];

Swift code:

let data = FileManager.default.contents(atPath: path)

To get this work you just need to do:

NSURL *imgPath = [[NSBundle mainBundle] URLForResource:@"search" withExtension:@"png"];
NSString*stringPath = [imgPath absoluteString]; //this is correct


//you can again use it in NSURL eg if you have async loading images and your mechanism
//uses only url like mine (but sometimes i need local files to load)
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:stringPath]];
UIImage *ready = [[[UIImage alloc] initWithData:data] autorelease];

Make sure your local URL starts with "file://" then you would just have to do this:

 NSData *fileData = [NSData dataWithContentsOfFile:fileURL.path];
