nsmutabledictionary

问题 The title is a bit confusing...I'll explain I have an NSMutableArray I am populating with NSMutableDictionary objects. What I am trying to do is before the dictionary object is added to the array, I need to check whether any of the dictionaries contain a value equal to an id that is already set. Example: Step 1: A button is clicked setting the id of an object for use in establishing a view. Step 2: Another button is pressed inside said view to save some of its contents into a dictionary, then

问题 All, I'm trying to send the NSMutableDictionary "response" to another class of mine, or rather, have the other class pull the dictionary from this class. When the other class uses the "getResponse" method, it returns null. The code I have attached is my XML parser, which is what puts the information I need into the dictionary. At the very bottom is the method that shows "(null)" in the NSLog. I have commented it for you. EDIT: I do use the initXMLParser method to initialize in the other class

问题 I'm trying to use an NSMutableDictionary to pair my custom classes object with a UIButton as it's key. The UIButton that is the key is also a member of the object that I want to store as the object in the NSMutableDictionary. My Class definition looks like ths: @interface ClassA : NSObject { @public UIButton *button1; UIButton *button2; UILabel *label; } @property (nonatomic, retain) UIButton *button1; @property (nonatomic, retain) UIButton *button2; @property (nonatomic, retain) UILabel

问题 So I'm storing block actions into a nsmutabledictionary and then recalling them when a response comes back on a websocket. This turns async request into a block syntax. Here's the stripped down code: - (void)sendMessage:(NSString*)message responseAction:(void (^)(id))responseAction { NSString *correlationID = (NSString*)[[message JSONValue] objectForKey:@"correlationId"]; [self.messageBlocks setObject:responseAction forKey:correlationID]; NSLog(@"Sending message: %@", correlationID);

问题 I want to remove duplicates from nsmutablearray. Array Structure :- ( { "act_end_date" = ""; "act_entry_date" = "13/11/2014"; "act_recurrrance_type" = Daily; "act_start_date" = "2014-11-13"; "row_id" = 0; "act_id" = 2; } { "act_end_date" = ""; "act_entry_date" = "13/11/2014"; "act_recurrrance_type" = Daily; "act_start_date" = "2014-11-13"; "row_id" = 1; "act_id" = 2; } { "act_end_date" = ""; "act_entry_date" = "16/11/2014"; "act_recurrrance_type" = Daily1; "act_start_date" = "2014-11-15";

问题 This question already has answers here : How can i get Original order of NSDictionary/NSMutableDictionary? (5 answers) Closed 5 years ago . I am trying set objects for particular keys to an NSMutableDictionary in a for loop The code: for(int k =0;k<currenyArry.count;k++) { [_currenies setObject:@"0" forKey:currenyArry[k]]; } Here, _currenies is an NSMutableDictionary and currenyArry is an NSMutableArray . For example, currentArry is: [1,3,5,10,100,500,1000]; After setting the objects in

问题 I need to filter data in UITableview by text entered in UISearchbar . I followed this example but there data in NSMutableArray and I can't alter it under my requirements. My data is NSMutableDictionary . I'm stuck on this for long time. My data: NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *path = [[documentPaths lastObject] stringByAppendingPathComponent:@"data.plist"]; NSDictionary *dict = [NSDictionary

问题 I have the following code fragment: NSString* value = @"value"; NSString* key = @"key"; NSMutableDictionary* foo = [NSMutableDictionary dictionary]; NSDictionary* bar = [NSDictionary dictionary]; NSAssert([bar isKindOfClass: [NSMutableDictionary class]], @""); // passes the assert as both are NSCFDictionary; NSAssert([bar respondsToSelector: @selector(setValue:forKey:)], @""); // passes the assert because it NSCFDictionary does respond to the selector [foo setValue:value forKey:key]; // no
