尝试

NSString *newID=@"12390,12391,12392,12394,12394,12395,12396";
NSArray *arrays = [newID componentsSeparatedByString:@","];
NSMutableArray *arr = [NSMutableArray arrayWithArray:arrays];

Answer 4

NSString *newID=@"12390,12391,12392,12394,12394,12395,12396";  
NSArray *arrayIds = [newID componentsSeparatedByString:@","];  
NSString *str1=[arrayIds objectAtIndex:0];  
NSString *str2=[arrayIds objectAtIndex:1];  
.  
.  
.  

Answer 5

NSString * newID = @“12390,12391,12392,12394,12394,12395,12396”;

array = [newID componentsSeparatedByString：@“，”];

（如果你使用另一种方法）[array retain];
