DFInvocation

This project is a reference to other people's code. If I use your code, please let me know.

This project is developed on the basis of NSInvocation. A dynamic call function that can be used for multiple parameters. At the same time,get the return value of the function .

Require

• iOS 8.0+
• Objective-C

Installation

There are two ways to use DFInvocation in your project:

• using CocoaPods
• by cloning the project into your repository

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the Get Started section for more details.

Podfile

platform :ios, '8.0'
target "ProjectName" do
pod 'DFInvocation' '1.0.0'
end

How to Use

Import the header file

#import "NSObject+DFInvocation.h"

Call the method which without arguments,just like this :

[self dfPerformSelector:@selector(customClassMethodWithoutArgument)];

Call the method which with only one argument, just like this:

NSArray *arguments = @[@"i am argumen 1", @"i am argumen 2"];
NSArray *resutlA = [self dfPerformSelector:@selector(customClassMethodWithOneArgument:) argument:arguments];

If the method has many arguments,your could call like this:

NSArray *arguments = @[@"i am argumen 1", @"i am argumen 2"];
NSArray *argumentsEx = @[arguments, @(1), @(CGRectMake(0, 0, 100, 200))];
NSArray *resutlEx = [self dfPerformSelector:@selector(customClassMethodWithManyArguments:argument2:argument3:) arguments:argumentsEx];

when the method argument is block, you could call like this:

First of all, Declaring "block"

void (^blk)(NSInteger ) = ^(NSInteger count) {
    NSLog(@"block %@", @(count));
};

and then call dfPerformSelector like this:

[self  dfPerformSelector:@selector(block:) argument:blk];

In the same time, if the method will return value, "dfPerformSelector" also return it.

How to Catch An Error

If your want to catch error when perform selector is mistake, you should change this to "YES".(Default is "NO")

[DFInvocationHelper sharedHelper].isCatchAndThrow = YES;
