My attempt to draw UIBezierPath lines with different colors is failing me. All the lines change to the currently selected color. All my path and information are all stored in an NSMutableArray called pathInfo. In path info I drop in array that contains the Path, Color, Width, and Type of line. This works fine except all the lines turn to whatever color the user has selected. I would appreciate any help greatly! - (void)drawRect:(CGRect)rect { UIBezierPath *drawPath = [UIBezierPath bezierPath]; drawPath.lineCapStyle = kCGLineCapRound; drawPath.miterLimit = 0; for (int i = 0; i < [pathInfo count

I have an array with custom objects. Each array item has a field named "name". Now I want to remove duplicate entries based on this name value. How should I go about achieving this. Thanks in advance. You might have to actually write this filtering method yourself: @interface NSArray (CustomFiltering) @end @implementation NSArray (CustomFiltering) - (NSArray *) filterObjectsByKey:(NSString *) key { NSMutableSet *tempValues = [[NSMutableSet alloc] init]; NSMutableArray *ret = [NSMutableArray array]; for(id obj in self) { if(! [tempValues containsObject:[obj valueForKey:key]]) { [tempValues

I have an array like this: array: ( ( "http://aaa/product/8_1371121323.png", "http://aaa/product/14_1371123271.png" ), ( "http://aaa/product/9_1371121377.png" ) ) and I have to create another array from that one like this array: ( "http://aaa/product/8_1371121323.png", "http://aaa/product/14_1371123271.png", "http://aaa/product/9_1371121377.png" ) How can I do that? Is it possible to combine all the objects and separate them using some string? Sample Code : NSMutableArray *mainArray = [[NSMutableArray alloc] init]; for (int i = 0; i < bigArray.count ; i++) { [mainArray addObjectsFromArray:

I've contacts array where each contact is a dictionary. Each contact has a key "contact_type" which is an NSNumber. Contact type basically represents whether its a Facebook, LinkedIn or Mail contact etc. I've a search array which holds only NSNumber of contact_type's. What I want is to make a temporary array of contacts which I want to search using my search array. I am facing trouble using NSPredicate to create searched contacts array. Can some one guide me on how to do it? NSArray *contacts = ...; //your array of NSDictionary objects NSPredicate *filter = [NSPredicate predicateWithFormat:@

I am trying to sort an array of managed objects alphabetically. The attribue that they need to be sorted by is the name of the object (NSString) with is one of the managed attributes. Currently I am putting all of the names in an array of strings and then using sortedNameArray = [sortedNameArray sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; and then enumerating them back into an array with the objects. This falls apart when two names are the same so I really need to be able to sort by one attribute. How should I go about doing this? Dancreek Use NSSortDescriptor. Just

How can I convert an NSArray to an NSDictionary , using an int field of the array's objects as key for the NSDictionary ? - (NSDictionary *) indexKeyedDictionaryFromArray:(NSArray *)array { id objectInstance; NSUInteger indexKey = 0U; NSMutableDictionary *mutableDictionary = [[NSMutableDictionary alloc] init]; for (objectInstance in array) [mutableDictionary setObject:objectInstance forKey:[NSNumber numberWithUnsignedInt:indexKey++]]; return (NSDictionary *)[mutableDictionary autorelease]; } Try this magic: NSDictionary *dict = [NSDictionary dictionaryWithObjects:records forKeys:[records

What is __NSArrayI and __NSArrayM? __NSArrayI(or M) cause "unrecognized selector" error. How to convert to NSArray? I did test to parse json, twitter api. http://api.twitter.com/1/followers/ids.json?cursor=-1&screen_name=twitterapi ==> works fine. parsed object is NSCFDictionary class. (This dictionary contains __NSArrayM class) http://api.twitter.com/1/statuses/user_timeline.json?&screen_name=twitterapi ==> error. parsed object is __NSArrayM class. __NSArrayI is a code-word for an immutable array - that is, a "regular" NSArray which you cannot change. __NSArrayM is a code-word for a mutable
