I finally solve my problem : The mapping method in the controller should be let json : AnyObject! = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &error) if (error != nil) { return completionHandler(nil, error) } else { var customer = Mapper<Customer>().mapArray(json)! //Swift 2 var customer = Mapper<Customer>().mapArray(JSONArray: json)! //Swift 3 } If it can help someone.
What you’re doing should work fine. For example NSArray *a = [NSArray arrayWithObjects:@”Foo”, @”Bar”, @”Baz”, nil]; NSLog(@”At index %i”, [a indexOfObject:@”Bar”]); Correctly logs “At index 1” for me. Two possible foibles: indexOfObject sends isEqual messages to do the comparison – you’ve not replaced this method in a category? Make sure you’re testing against NSNotFound for … Read more
I would declare a readonly NSArray in your header and override the getter for that array to return a copy of a private NSMutableArray declared in your implementation. Consider the following. Foo.h @interface Foo @property (nonatomic, retain, readonly) NSArray *array; @end Foo.m @interface Foo () @property (nonatomic, retain) NSMutableArray *mutableArray @end #pragma mark – @implementation … Read more
The problem is that CGPoint is actually just a C structure it is not an object: struct CGPoint { CGFloat x; CGFloat y; }; typedef struct CGPoint CGPoint; If you are on the iPhone you can use the NSValue UIKit additions to convert the CGPoint to an NSValue object. See this previous answer for examples: … Read more
If you create an NSArray you won’t be able to add elements to it, since it’s immutable. You should try using NSMutableArray instead. Also, you inverted the order of alloc and init. alloc creates an instance and init initializes it. The code would look something like this (assuming getData is a global function): NSMutableArray *stringArray … Read more
NSArray* newArray = [firstArray arrayByAddingObjectsFromArray:secondArray]; Or using mutable array version just add to it all objects from another array: [myMutableArray addObjectsFromArray:secondArray];
There is also a shorthand of doing this: NSArray *persons = @[person1, person2, person3]; It’s equivalent to NSArray *persons = [NSArray arrayWithObjects:person1, person2, person3, nil]; As iiFreeman said, you still need to do proper memory management if you’re not using ARC.
Assuming there’s no worry about escaping/unescaping commas contained within the strings, it should be this simple: NSArray *items = [theString componentsSeparatedByString:@”,”];
copy and mutableCopy are defined in different protocols (NSCopying and NSMutableCopying, respectively), and NSArray conforms to both. mutableCopy is defined for NSArray (not just NSMutableArray) and allows you to make a mutable copy of an originally immutable array: // create an immutable array NSArray *arr = [NSArray arrayWithObjects: @”one”, @”two”, @”three”, nil ]; // create … Read more
indexOfObjectIdenticalTo checks for the exact same id (same address). indexOfObject checks that isEqual: returns YES.
