<Error>:CGDataConsumer(url_close):写入失败:-15

Question

<Error>: CGDataConsumer(url_close): write failed: -15.
<Error>: CFURLCreateDataAndPropertiesFromResource: failed with error code -15.

有谁知道什么可能触发这个错误及其含义？

Answer 1

我之前在使用错误定义的URL时看到了这一点.例如:

NSString *f = [NSTemporaryDirectory() stringByAppendingPathComponent:@"tmp.txt"];

// This is an invalid file url and will fail when you try to save to it.
NSURL *invalidFileURL = [NSURL URLWithString:f];

// This URL is acceptable.
NSURL *validFileURL = [NSURL fileURLWithPath:f isDirectory:NO];
