您好我有需要被排序(字母表上名)對象的數組目標c溢出陣列中的多個陣列對的UITableView分組
ArtistVO *artist1 = [ArtistVO alloc];
artist1.name = @"Trentemoeller";
artist1.imgPath = @"imgPath";
ArtistVO *artist2 = [ArtistVO alloc];
artist2.name = @"ATrentemoeller";
artist2.imgPath = @"imgPath2";
ArtistVO *artist3 = [ArtistVO alloc];
artist3.name = @"APhextwin";
artist3.imgPath = @"imgPath2";
//NSLog(@"%@", artist1.name);
NSMutableArray *arr = [NSMutableArray array];
[arr addObject:artist1];
[arr addObject:artist2];
[arr addObject:artist3];
NSSortDescriptor *lastDescriptor =
[[[NSSortDescriptor alloc]
initWithKey:@"name"
ascending:YES
selector:@selector(localizedCaseInsensitiveCompare:)] autorelease];
NSArray * descriptors =
[NSArray arrayWithObjects:lastDescriptor, nil];
NSArray * sortedArray =
[arr sortedArrayUsingDescriptors:descriptors];
NSLog(@"\nSorted ...");
NSEnumerator *enumerator;
enumerator = [sortedArray objectEnumerator];
ArtistVO *tmpARt;
while ((tmpARt = [enumerator nextObject])) NSLog(@"%@", tmpARt.name);
工作正常。但現在我需要在一個分組的UITableView
self.sortedKeys =[[NSArray alloc]
initWithObjects:@"{search}",@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",@"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z",nil];
NSMutableArray *arrTemp0 = [[NSMutableArray alloc]
initWithObjects:@"000",nil];
NSMutableArray *arrTemp1 = [[NSMutableArray alloc]
initWithObjects:@"Andrew",@"Aubrey",@"Aalice", @"Andrew",@"Aubrey",@"Alice",@"Andrew",@"Aubrey",@"Alice",nil];
NSMutableArray *arrTemp2 = [[NSMutableArray alloc]
initWithObjects:@"Bob",@"Bill",@"Bianca",@"Bob",@"Bill",@"Bianca",nil];
NSMutableArray *arrTemp3 = [[NSMutableArray alloc]
initWithObjects:@"Candice",@"Clint",@"Chris",@"Candice",@"Clint",@"Chris",nil];
NSMutableArray *arrTemp4 = [[NSMutableArray alloc]
initWithObjects:@"Dandice",@"Dlint",@"Dhris",nil];
NSDictionary *temp =[[NSDictionary alloc]
initWithObjectsAndKeys:arrTemp0, @"{search}", arrTemp1,@"A",arrTemp2,
@"B",arrTemp3,@"C",arrTemp4,@"D",nil];
self.tableContents =temp;
拆分此awway彌補使用情況,以便與第一個字母的所有藝術家「」進來一個陣......與「B」在一個陣列等。
我需要做一些字符串比較還是有更好的方法?
謝謝。認爲可能有一個更小的方法,如:「通過選擇器從數組中返回數組」類似於排序描述符 – 2010-10-14 12:13:53
