Plist存图片

把图片转为base64的字符串存到数据库中或者plist文件中，然后用到的时候再取出来

//获取沙盒路径，

NSString *path_sandox = NSHomeDirectory();

//创建一个存储plist文件的路径

NSString *newPath = [path_sandox stringByAppendingPathComponent:@"/Documents/pic.plist"];

NSMutableArray *arr = [[NSMutableArray alloc] init];

//把图片转换为Base64的字符串

NSString *image64 = [self encodeToBase64String:image];

[arr addObject:image64];

//写入plist文件

if ([arr writeToFile:newPath atomically:YES]) {

NSLog(@"写入成功");

};

这样就存起来的，然后用到的时候再利用存储的字符串转化为图片。

NSData *_decodedImageData = [[NSData alloc] initWithBase64Encoding:image64];

UIImage *_decodedImage = [UIImage imageWithData:_decodedImageData];

//UIImage图片转成Base64字符串：

UIImage *originImage = [UIImage imageNamed:@"originImage.png"];

NSData *data = UIImageJPEGRepresentation(originImage, 1.0f);

NSString *encodedImageStr = [data base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

//Base64字符串转UIImage图片：

NSData *decodedImageData = [[NSData alloc]

initWithBase64EncodedString:encodedImageStr options:NSDataBase64DecodingIgnoreUnknownCharacters];

UIImage *decodedImage = [UIImage imageWithData:decodedImageData];
