Hello everyone
I hope to add objects to a NSMutableArray "myArray", The NSMutableArray is the array for FileObj which has a NSString property "fileName"
#import <UIKit/UIKit.h>
@interface FileObj : NSObject {
NSString *fileName;
}
-(void) setfileName:(NSString *)s ;
-(NSString *) getfileName ;
@end
//
// File.m//
#import "File.h"
@implementation FileObj
-(void) setfileName:(NSString *)s ;
{
fileName=s;
}
-(NSString *) getfileName ;
{
return fileName;
}
@end
I initialize the myArray here:
NSMutableArray *temarray;
temarray=[[NSMutableArray alloc] init];
self.myArray=temarray;
[temarray release];
the codes to add object to myArray
FileObj *newobj=[[FileObj alloc]init ];
NSString *fieldValue2 = [[NSString alloc] initWithUTF8String:@"aaaa"];
[newobj setfileName:fieldValue2];
[myArray addObject:newobj];
[fieldValue2 release]; //**if I enabled the line, it will cause crash**
//**if I disable the line, it will cause memory leak**
[newobj release];
Welcome any comment
Thanks
