使用XCode Clang(静态分析器)发现内存泄露

XCode中引入了静态分析器,用于发现普通编译错误以外的错误

选择Build->Build and Analyze

请看下面这段代码

#import <Foundation/FOundation.h>

int main(int agrc, const char *argv[])
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSDate *date = [[NSDate alloc] init];
    NSLog(@"The time is: %@", date);
    
    [pool drain];
    return 0;
}

 

上面这段代码中, date对象在创建后没有被释放

所以, 我们应该加上[date release]

正确的代码

#import <Foundation/FOundation.h>

int main(int agrc, const char *argv[])
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSDate *date = [[NSDate alloc] init];
    NSLog(@"The time is: %@", date);
    [date release];
    [pool drain];
    return 0;
}
