Question

I am making a call to a database. After my call, I’ve found leaks in NSString. Anybody have a solution to remove it?

 NSString *pic = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 5)];

In above code, I found 90% leaks. I just read data from database.

Answer 1

please explain the question well else others can’t identify your exact problem.

I think you are you are assigning the value of [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 5)]; to your class object property.

You can release the assigned class string property in the corresponding class dealloc method.Also set it nil.

Example:

if you are doing

YourClass *classObj =[ YourClass  alloc] init];

classObj.myStringvariable = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 5)];

the class structure will like

@interface YourClass {

    NSString *myStringvariable ;

}

@property (nonatomic,retain)  NSString *myStringvariable ;

.m file will be

@synthesise myStringvariable ;


-(void)init{

 myStringvariable  = @"";

}

-(void)dealloc{

 [myStringvariable  release];
 myStringvariable  = nil;
}

Check it.. this structure will not show memory leak.
