UIImage和Base64互转

1.UIImage转成Base64

+ (NSString *)ImageTobase64:(NSString *)imagename {
    UIImage *_originImage = [UIImage imageNamed:imagename];
    NSData *_data = UIImageJPEGRepresentation(_originImage, 1.0f);
    NSString *_encodedImageStr = [_data base64Encoding];
    return _encodedImageStr;
}

 

2.Base64转成UIImage

+ (UIImage *)base64ToImage:(NSString *)_encodedImageStr { 
　　NSData *_decodedImageData = [[NSData alloc] initWithBase64Encoding:_encodedImageStr]; 
　　UIImage *_decodedImage = [UIImage imageWithData:_decodedImageData];
　　return _decodedImage;
}
