iOS代码
-(void)base64Image{
NSString *path = [[NSBundle mainBundle] pathForResource:@"ll.png" ofType:nil];
UIImage *savedImage = [[UIImage alloc] initWithContentsOfFile:path];
NSData *data =UIImageJPEGRepresentation(savedImage, 1.0);
NSString *encodedImgStr = [data base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
// NSString *path1 = [[NSBundle mainBundle] pathForResource:@"aa.jpg" ofType:nil];
// UIImage *savedImage1 = [[UIImage alloc] initWithContentsOfFile:path1];
// NSData *data1 =UIImageJPEGRepresentation(savedImage1, 1.0);
// NSString *encodedImgStr1 = [data1 base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
NSString *data_url = [NSString stringWithFormat:@"%@",encodedImgStr];
NSLog(@"++++----%@",data_url);
NSMutableDictionary *dic = [[NSMutableDictionary alloc] initWithCapacity:10];
[dic setObject:data_url forKey:@"imageString"];
[ZHRequestTools HTTPPostWithUrl:@"/Api/v1/index/test" Parames:dic commplete:^(id result, NSInteger StatusCode) {

总结
1、前端将图片转换成base64 是这种格式的data:image/jpeg;base64,asaskjxibasjh(base64字符串)
2、iOS 将图片转换base64 没有 data:image/jpeg;base64, 要额外获取文件的mime 拼接上
