Question

我正在尝试在实用程序模板应用程序的侧视图上显示一些数据，但应用程序在viewDidLoad方法结束时中止。我是iOS新手，可以做一些指导。

[super viewDidLoad];
self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor];
NSString *thePath = [[NSBundle mainBundle] pathForResource:@"SavedData"ofType:@"plist"];
NSMutableDictionary *tempRootDictionary;
NSMutableArray *tempMutableArray;
if (thePath && (tempRootDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:thePath])) {
    NSArray *keys = [tempRootDictionary allKeys];
    int keysCount = [keys count];
    tempMutableArray = [NSMutableArray arrayWithCapacity:keysCount];
    for (int i=0; i<keysCount; i++) {
        NSDictionary *dictionary = [tempRootDictionary objectForKey:[keys objectAtIndex:i]];
        MyModelObject *aModelObject = [[MyModelObject alloc] init];
        [aModelObject setName:[dictionary objectForKey:@"name"]];
        [aModelObject setContext:[dictionary objectForKey:@"context"]];
        [aModelObject setUsername:[dictionary objectForKey:@"username"]];
        [aModelObject setPassword:[dictionary objectForKey:@"password"]];
        [tempMutableArray addObject:aModelObject];
        [aModelObject release];
        [dictionary release];
    }
} else {
    return;
}

非常感谢帮助，非常感谢......

我在发布的代码中看到的唯一明显问题是：

[dictionary release];

在您设置字典的行上，您只获得对tempRootDictionary中对象的引用，而不是它的新alloc'd实例。所以不要发布它。删除该行。
