API The way

Baidu intelligence （ Text recognition ）, Baidu API The map didn't provide OC An example of , Here you can find 

- (void)OCTest:(NSString*)token {
//***********post request ********************//

NSString *testURL =[NSString stringWithFormat:@"https://aip.baidubce.com/rest/2.0/ocr/v1/idcard?access_token=%@",token];

testURL = [testURL stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

NSURL *url = [NSURL URLWithString:testURL];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

// Set the request method 

request.HTTPMethod = @"POST";

// Set request body 

UIImage *testImage = [UIImage imageNamed:@"test.jpg"];

NSData *imageData = UIImagePNGRepresentation(testImage);

NSString *baseStr = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

NSString *urlEncode= (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(

NULL,

(__bridge CFStringRef)baseStr,

NULL,

(CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",

CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)));
NSLog(@"urlEncode is %@",urlEncode);
NSString *str =[NSString stringWithFormat:@"image=%@&id_card_side=%@",urlEncode,@"front"];

NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPBody = data;

NSURLSession *session = [NSURLSession sharedSession];

NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {

//

if (error) {

NSLog(@"error is %@",error);

}else

{

NSLog(@"data is %@",data);

NSDictionary *dic= [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];

NSLog(@" From the analysis dic is %@",dic);

}

}];

[dataTask resume];
}

If UI No design to take pictures UI, Here we suggest you use SDK, Good stability , Efficient .

SDK The way

If the real machine runs with an error report , hold lib All the simulators in are removed .

Real machine running error 、Archive/IPA/Upload AppStore Times wrong "Unsupported Architecture. Your executable contains unsupported architecture '[x86_64, i386]..."

For the convenience of developers debugging ,AipBase.framework A combination of simulator and real machine architecture , Before going online , Use lipo Tool to remove the relevant architecture , Reference resources ：

cd lib

# Use lipo -info You can see the included architectures 

lipo -info AipBase.framework/AipBase # Architectures in the fat file: AipBase are: i386 x86_64 armv7 armv7s arm64

# remove x86_64, i386

lipo -remove x86_64 AipBase.framework/AipBase -o AipBase.framework/AipBase

lipo -remove i386 AipBase.framework/AipBase -o AipBase.framework/AipBase

lipo -remove x86_64 AipOcrSdk.framework/AipOcrSdk -o AipOcrSdk.framework/AipOcrSdk

lipo -remove i386 AipOcrSdk.framework/AipOcrSdk -o AipOcrSdk.framework/AipOcrSdk

# Look again 

lipo -info AipBase.framework/AipBase # Architectures in the fat file: AipBase are: armv7 armv7s arm64

If you want to modify SDK Of UI, have access to AipOrcSdk The source code , Programming on the shoulders of giants , It's also very fragrant ！
