Problem 在表视图里面通过流畅而直观的动画来移动改变cell 和section 的位置 Solution 使用 moveSection: toSection 表视图方法，将部分移动到一个新的位置。您还可以使用moveRowAtIndexPath: toIndexPath: 方法移动表视图单元格从当前位置到另一个新的地方 Discussion 移动表视图细胞和部分不同于交换他们。让我们来看一个例子，这将使这个更容易理解。比方说，你有三个部分中的表视图：第A， B和C。如果您移动部分A到C组，表视图会注意到这一举动，然后将B部分转移到A段之前的位置，并将移动C节第B的前面的位置但是，如果B段被移动到C组，表视图不会有移动A节可言，因为它是坐在上面，并不会与重新定位干扰B段和C在这种情况下， B段将被移动到C段和C段第B移动单元格时，同样的逻辑也将使用表格视图。 为了证明这一点，让我么创建一个表视图，并拥有三个section，每个section包含三个预先加载的三个cell。让我们开始我们的视图控制器的实现文件： #import “ViewController.h ” static NSString *CellIdentifier = @“CellIdentifier”; @interface ViewController () <UITableViewDelegate

#import "ViewController.h" @interface ViewController () @end @implementation ViewController - ( void )viewDidLoad { [ super viewDidLoad ]; [ self ninePic ]; // Do any additional setup after loading the view, typically from a nib. } -( void )ninePic { NSMutableArray *_imageArr = [ NSMutableArray arrayWithCapacity : 10 ]; for ( int i = 0 ; i < 3 ; i++) { for ( int j = 0 ; j < 3 ; j++) { CGRect rect = CGRectMake ( 18.75 +j* 118.75 , 200 +i* 118.75 , 100 , 100 ); UIImageView *imageView = [[ UIImageView alloc ] initWithFrame :rect]; imageView. backgroundColor = [ UIColor purpleColor ]; [ self .

I have a list of strings in an NSMutableArray , and I want to sort them into alphabetical order before displaying them in my table view. How can I do that? There is the following Apple's working example, using sortedArrayUsingSelector: and localizedCaseInsensitiveCompare: in the Collections Documentation : sortedArray = [anArray sortedArrayUsingSelector: @selector(localizedCaseInsensitiveCompare:)]; Note that this will return a new sorted array. If you want to sort your NSMutableArray in place, then use sortUsingSelector: instead, like so: [mutableArray sortUsingSelector:@selector

I am doing JSON parsing and I want to show my parsed data in a UITableView . For that, I am trying to assign parsed data from NSMutableDictionary to NSArray to show in the table view but the array returns null . Here my array returns null value; NSMutableDictionary *tempDict1; NSArray *arr = [[tempDict1 valueForKey:@"rates"] componentsSeparatedByString:@";"]; code - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; self.responseData = nil; // NSArray

I have a navigational based application which has multiple views. Is it possible to use one single NSMutableArray for the whole applicaiton? Can i add objects to that NSMutableArray in one view and then remove object from the same NSMutableArray from some other view? I tried myappAppDelegate *appDelegate = (myappAppDelegate *)[[UIApplication sharedApplication] delegate]; but it gives me null when i try to access appDelegate's array. If anyone can give me any idea or helping link or tutrorial. Thanks in advance. If you are having multiple views in your application, and in that case you want to

I have NSMutableArray with 50 array elements. I need to generate randomly without any repetition. Can you suggest some sample codes. here is sample to get random int less than 1000. int y = arc4random() % 1000; to stay without duplicates, just check before inserting Create a local mutablearray copy of main array, and after getting random value, remove object available at random index from local array, process it till array count is 1. James Webster I have assumed you want to generate numbers. This is the answer I have used for generating M random numbers from N. Though it doesn't add them into

I created a simple database and put in NSUserDefaults. My database is NSMutableArray which has dictionaries and arrays inside in it. When I create NSMutableArray from NSUSerDefaults I can't add any objects to my mutable objects inside my NSMutableArray. Here is my code: NSMutableArray *arrayOne = [NSMutableArray arrayWithContentsOfFile:[self createEditableCopyOfIfNeededWithFileName:@"Form.plist"]]; NSUserDefaults *ayarlar = [NSUserDefaults standardUserDefaults]; [ayarlar setObject:arrayOne forKey:@"form"]; NSMutableArray *arrayTwo = [NSMutableArray arrayWithArray:[[ayarlar objectForKey:@"form"
