将GIF图像转换为nsdata [英] Converting GIF images to nsdata

问题描述

我有一个iPhone应用程序，需要将图像以BLOB格式保存到数据库中.问题是，如果图像为.gif格式，则无法将其转换为NSDATA格式，因此我无法将其以BLOB格式保存到数据库中.

I have an iPhone application that needs to save an image onto the database in BLOB format. The problem is that if the image is in .gif format then it cannot be converted to NSDATA format and hence i am not been able to save that onto the database in BLOB format.

我该怎么办?

请帮助一些代码.

先谢谢了 欢乐

推荐答案

可以将gif图像转换为NSData ...下面是代码段:

A gif image can be converted into NSData...Here's the code snippet:

NSString *pathForGif = [[NSBundle mainBundle] pathForResource: @"gifFile" ofType: @"gif"];

NSData *gifData = [NSData dataWithContentsOfFile: pathForGif];

NSLog(@"Data: %@", gifData);

日志看起来像这样:
