How to use it

Calling class method

    //============Calling class method============//
    Class MFMailComposeViewController = (NSClassFromString(@"MFMailComposeViewController"));
    
    if ([MFMailComposeViewController canSendMail] == YES) {
        NSLog(@"can send mail");
    }

Calling instance method

    // please read UIAutocorrectInlinePrompt.h at https://github.com/nst/iOS-Runtime-Headers/blob/master/Frameworks/UIKit.framework/UIAutocorrectInlinePrompt.h
    //============Calling instance method============//
    //============UIAutocorrectInlinePrompt============//
    Class UIAutocorrectInlinePrompt = NSClassFromString(@"UIAutocorrectInlinePrompt");
    id obj = [[UIAutocorrectInlinePrompt alloc] init];
    
    /**
     * using NSObject's performSelector:withObject method
     */
    if ([obj respondsToSelector:@selector(setFrame:)]) {
        // wrap CGRect with object, performSelector:withObject: require object
        NSValue *value = [NSValue valueWithCGRect:CGRectMake(0, 0, 100, 100)];
        [obj performSelector:@selector(setFrame:) withObject:value];
    }
    
    /**
     * using NSInvocation to support limitless argument
     */
    SEL setFrameSelector = @selector(setFrame:);
    if ([obj respondsToSelector:setFrameSelector]) {
        CGRect rect = CGRectMake(0, 0, 200, 200);
        
        NSInvocation *inv = [NSInvocation invocationWithMethodSignature:[obj methodSignatureForSelector:setFrameSelector]];
        [inv setSelector:setFrameSelector];
        [inv setTarget:obj];
        [inv setArgument:&rect atIndex:2];  //arguments 0 and 1 are self and _cmd respectively, automatically set by NSInvocation
        [inv invoke];
    }
