Question

我刚刚遇到苹果过去提供的旧拼图资料。当我想知道是否有人可以提供帮助时，我遇到了一些错误。

我收到错误：错误：'endTrackingPiece：position：'参数2的不兼容类型错误：'continueTrackingPiece：position：'

参数2的不兼容类型

- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
    UITouch*                touch = [touches anyObject];

    //Check if we have a double-tap in the piece view and notify the application controller or begin tracking piece dragging
    if([touch tapCount] >= 2)
    [(AppController*)[[UIApplication sharedApplication] delegate] resetPiece:self];
    else {
        _tracking = YES;
        [(AppController*)[[UIApplication sharedApplication] delegate] beginTrackingPiece:self position:[touch locationInView]];
    }
}

- (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
    UITouch*                touch = [touches anyObject];

    //Continue tracking piece dragging
    if(_tracking)
    [(AppController*)[[UIApplication sharedApplication] delegate] continueTrackingPiece:self position:[touch locationInView]];
}

- (void) touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
{
    UITouch*                touch = [touches anyObject];

    //Finish tracking piece dragging
    if(_tracking) {
        [(AppController*)[[UIApplication sharedApplication] delegate] endTrackingPiece:self position:[touch locationInView]];
        _tracking = NO;
    }
}

提前致谢

这里的问题是locationInView期望UIView *作为参数，请参阅此处的参考：

http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITouch_Class/Reference/Reference.html

因此，对于这三行中的每一行，修复都是要改变

[touch locationInView]

到

[touch locationInView: self]

在此之前，您可能需要更改项目文件中的基本SDK，如果它指的是Aspen1.2.sdk，我找到的版本是。我将它更新到iOS4.3（这是在XCode 4中，我应该添加。）

如果您想要删除弃用警告，请更改

_puzzles = [[[NSFileManager defaultManager] directoryContentsAtPath:path] mutableCopy];

到

_puzzles = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:NULL] mutableCopy];

在AppController.m _resetPuzzle。

完成上述操作后，我得到一个在iOS模拟器中运行的干净建筑项目。确保你的音量没有静音，否则你会错过“Yay！”当你完成一个谜题：）
