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 method.

Example

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

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    NSString *path = [[NSBundle mainBundle] pathForResource:@"demo" ofType:@"mg"];
    NSURL *scriptUrl = [NSURL fileURLWithPath:path];
    MFContext *context = [[MFContext alloc] init];
    [context evalMangoScriptWithURL:scriptUrl];
    return YES;
}

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.view addSubview:[self genView]];
}

- (UIView *)genView{
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(50, 100, 150, 200)];
    return view;
}

@end

class ViewController:UIViewController{

- (UIView *)genView{
    UIView *view = UIView.alloc().initWithFrame:(CGRectMake(50, 100, 150, 200));
    view.backgroundColor = UIColor.redColor();
    return view;
}

}

Installation

CocoaPods

1. Add pod 'MangoFix' to your Podfile.

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

Usage

Objective-C

1. #import <MangoFix/MangoFix.h>
2. 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.
