I am trying to convert a Base64 image to an UIImage
in Objective C
.
我试图在目标C中将Base64图像转换为UIImage。
I am doing something like so :-
我正在这样做: -
(UIImage *)decodeBase64ToImage:(NSString *)strEncodeData {
NSData *data = [[NSData alloc]initWithBase64EncodedString:strEncodeData options:NSDataBase64DecodingIgnoreUnknownCharacters];
return [UIImage imageWithData:data];
}
But this function always returns nil
.
但是这个函数总是返回nil。
My Base64 string is like so :-
我的Base64字符串是这样的: -
https://pastebin.com/pwbvhN0G
I verified the validity of the image using https://codebeautify.org/base64-to-image-converter# and it displayed fine.
我使用https://codebeautify.org/base64-to-image-converter#验证了图像的有效性,它显示正常。
EDIT P.S I also include the data:image/png;base64
in the string.
EDIT P.S我还在数据库中包含数据:image / png; base64。
Is there a way I can fix this? Any help is appreciated.

If you follow the basic Apple developer tutorial,you can get the answer.But below the exact answer.
如果你按照基本的Apple开发人员教程,你可以得到答案。但下面的确切答案。
NSData *dataEncoded = [[NSData alloc] initWithBase64EncodedString:strEncoded options:0];
UIImage *image = [UIImage imageWithData:dataEncoded];
Also find the solution here Converting UIImage to NSData and NSData to NSString for posting images to a server
同时在此处找到解决方案将UIImage转换为NSData,将NSData转换为NSString,以便将图像发布到服务器
