How to get the value of variable within the blocks - ios

Question

Is there anyway to check the value of 'type' variable with completionHandler.
-(void)sendApiMethod:(NSString*)apiName ApiType:(NSString*)type
{
[SendAPI setAPIWithName:#"APIName" completionHandler:^(NSArray *errors) {
if([type isEqualToString:#"Login"])
{
/// Call Some Other function
}
}];
}

I wrote a small piece of code to verify if works (only reading your question I would say yes as Droppy)
I added all there code in a ViewController in a Simple View App.
some assumption:
- all code there for sake of semplicity ....
- I have added a singleton as it seems You are calling a class method.
- instance method is a bit rough, it simply saves name and block
- I added a typedef for blocks to better reading it.
#import "ViewController.h"
typedef void (^CompletionBlock)(NSArray *errors);
#interface SendAPI : NSObject
-(void)setAPIWithName:(NSString*)name completionHandler: (CompletionBlock)completionHandler;
+(void)setAPIWithName:(NSString*)name completionHandler: (CompletionBlock)completionHandler;
+(SendAPI*)sharedInstance;
#property (strong) CompletionBlock completionBlock;
#property (strong) NSString * name;
#end
#implementation SendAPI : NSObject
static SendAPI * _singleton = nil;
+(SendAPI*)sharedInstance
{
if (_singleton == nil)
{
_singleton = [[SendAPI alloc] init];
}
return _singleton;
}
-(void)setAPIWithName:(NSString*)name completionHandler: (CompletionBlock)completionHandler;
{
self.completionBlock = completionHandler;
self.name = [name copy];
__weak SendAPI * weakRef = self;
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(4 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
NSError* err = [NSError errorWithDomain: #"delayed"
code:1111
userInfo: #{#"info": self.name}
];
weakRef.completionBlock(#[err]);
});
}
+(void)setAPIWithName:(NSString*)name completionHandler: (CompletionBlock)completionHandler;
{
[[SendAPI sharedInstance]setAPIWithName:name completionHandler:completionHandler];
}
#end
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self sendApiMethod:#"HELLO" ApiType: #"Login"];
}
-(void)sendApiMethod:(NSString*)apiName ApiType:(NSString*)type{
[SendAPI setAPIWithName:#"APIName" completionHandler:^(NSArray *errors) {
if([type isEqualToString:#"Login"])
{
/// Call Some Other function
NSLog(#"%#", errors);
}
}];
}
it does LOG correctly
