NSArray writeToFile 第一次不工作（但下次工作）

Question

I am writing a huge NSArray of NSDictionaries. The file size when successfully written to a plist is about 549KB. The thing is, when I start my app, the first time I try to write it, it always returns NO (ie it didn't write), but then the next time it write just fine...Is there any way I can find out exactly what error occurred? Thanks.

Answer 1

Might be your array of dictionaries is empty? Try to debug your app.

Answer 2

Use NSData - writeToFile:options:error: instead and see what does the returned error (NSError) say.
