问题 It's a fairly simple builtin in python for example: x = range(0,100) How can I accomplish the same feat using objective-c methods? Surely there is something better than a NSMutableArray and a for-loop: NSMutableArray *x = [NSMutableArray arrayWithCapacity:100]; for(int n=0; n<100; n++) { [x addObject:[NSNumber numberWithInt:n]]; } Yes, I am aware that doing this is most likely not what I actually want to do (ex: xrange in python), but humor my curiosity please. =) Clarification: I would like

问题 I got a NSMutableArray which I want to add strings to. I need to check if that string already exists on the array before adding ths string to it. Does anyway know a good way to do it? Thanks! 回答1: If order doesn't matter, the simplest way would be to switch to using an NSMutableSet. Sets are unordered and NSSets and NSMutableSets can contain each object only once. Only a counted set (NSCountedSet) can contain the same object multiple times. If order does matter, continue using NSMutableArray,

问题 I have a NSDictionary and a NSArray : self.dataDic = [[[NSDictionary alloc] init] autorelease]; self.dataDicKey = [[[NSArray alloc] init] autorelease]; These are the key and value of my NSDictionary : self.dataDic = @{@"Ring Cloud" :@[@"Contact Cloud", @"Image Cloud", @"Data Cloud"], @"Ring Tools" :@[@"Sticker Market", @"Live Poll", @"Mail"], @"Ring Apps" :@[@"Studio", @"Player"]}; Now what I want is to insert all the key value of my self.dataDic into self.dataDicKey sequentially. That means

问题 I have a uitableview that crashes when row is greater than one. It makes no sense at all since their are two objects in the array. It works perfectly for object one, but not two.
