当我构建和分析我的应用程序时,在代码[array1 release]
附近发生潜在泄漏......为什么会发生这种情况......?提前感谢
- (void) touchOnFeaturedCatalog
{
searchId == 2;
//featuredCatalogName = @"23064_Leeds2010";
//NSString *response = [ZoomCatalogAppDelegate getResponseFromServer:[NSString stringWithFormat:@"http://www.zoomcatalog.com/iphone/iphone.php?catalog=%@&iphone=Yes&pdf=No", featuredCatalogName]];
NSString *response = [ZoomCatalogAppDelegate getResponseFromServer:@"http://www.zoomcatalog.com/iphone/supplier.php"];
//NSString *response = [ZoomCatalogAppDelegate getResponseFromServer:@"http://test.atvescape.com/articles.php"];
//NSLog(@"Response = %@", response);
NSArray *array = [response componentsSeparatedByString:@"##"];
[array retain];
for(int i = 0; i < array.count; i++)
{
NSLog(@"Trying outer loop.... %d, %@, %@", i, [array objectAtIndex:i], featuredCatalogName);
NSArray *array4 = [featuredCatalogName componentsSeparatedByString:[array objectAtIndex:i]];
if(array4.count > 1)
{

对不起..

如果您只在本地使用对象(在创建它的方法中),您可以自动释放它。在函数调用结束之前,由便捷方法创建或返回的对象可用。除非你需要其他地方的对象,否则我建议放弃retain
来电。经验法则是,无论何时拨打alloc
,new
,retain
或copy
,您都会释放该对象。但是,如果使用便捷方法,则返回的对象将自动生成。
您似乎调用了[global_ContentString retain];
,但未能调用相应的版本。
