Mango

MangoFix is a DSL which syntax is very similar to Objective-C，MangoFix is also an iOS App hotfix SDK. You can use MangoFix method replace any Objective-C or Swift method (Support Swfit from MangoFxi 1.5).

SWfit Example

import UIKit
import MangoFix

let aes128Key = "123456"
let aes128Iv = "abcdef"

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        let context = MFContext.init(aes128Key: aes128Key, iv: aes128Iv)
        let encryptedScriptURL = URL.init("Your URL")
        context.evalMangoScript(with: encryptedScriptURL)
        return true
    }

}

Objctive-C Example

#import "AppDelegate.h"
#import <MangoFix/MangoFix.h>

static NSString * const aes128Key = @"123456";
static NSString * const aes128Iv = @"abcdef";

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    MFContext *context = [[MFContext alloc] initWithAES128Key:aes128Key iv:aes128Iv];
    NSURL *scriptUrl = [NSURL URLWithString:@"Your URL"];
    [context evalMangoScriptWithURL:scriptUrl];
	return YES;
}

@end

Installation

CocoaPods

Add pod 'MangoFix' to your Podfile.

Run pod install or pod update.
Import <MangoFix/MangoFix.h>

Usage

Objective-C

#import <MangoFix/MangoFix.h>
exec Mango Script by [context evalMangoScriptWithSourceString:@""];

MFContext *context = [[MFContext alloc] init];
// exec mango file from network
[NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://xxx/demo.mg"]] queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
    NSString *script = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    [context evalMangoScriptWithSourceString:script];
}];
	
// exec local mango file
NSString *sourcePath = [[NSBundle mainBundle] pathForResource:@"demo" ofType:@"mg"];
NSString *script = [NSString stringWithContentsOfFile:sourcePath encoding:NSUTF8StringEncoding error:nil];
[context evalMangoScriptWithSourceString:script];

Mango Type usage

Mango support type as fllow:

void

equivalent to Objective-C `void`.

BOOL

equivalent to Objective-C `BOOL`.

uint

equivalent to Objective-C `unsigned char`、`unsigned short`、`unsigned int`、`unsigned long`、`unsigned long long`、`NSUInteger`.

int

equivalent to Objective-C `char`、`short`、`int`、`long`、`long long`、`NSInteger`.

double

equivalent to Objective-C `double`、`float`、`CGFloat`.

id

equivalent to Objective-C `id`.

OCClassName *

NSString *str = @"";

Block

Block blokc = ^id(id arg){};

Class

Class clazz = NSString.class();

struct

struct CGRect rect;// must add struct keyword  before structure variables defined.

Pointer

Pointer ptr; // C pointer.

CFunction

CFunction<returnType,arg1Type,arg2Type,...> ptr = CFunction("c function name"); // CFunction.
