MD7中的MDAudioPlayerTableViewCell崩溃

Question

我必须在我的iOS应用程序中使用MDAudioPlayerTableViewCell自定义tableView单元格.

它在iOS5和iOS6中运行良好,但在iOS7中运行不正常.

当我运行它时,出现以下错误崩溃消息并崩溃.

2013-10-03 21:07:36.401 MyApp[656:60b] -[UITableViewCellScrollView drawContentView:]: unrecognized selector sent to instance 0x15f71390
2013-10-03 21:07:36.403 MyApp[656:60b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITableViewCellScrollView drawContentView:]: unrecognized selector sent to instance 0x15f71390'

libc++abi.dylib: terminating with uncaught exception of type NSException

这是代码cellForRowAtIndexPath.

static NSString *CellIdentifier = @"Cell";

    MDAudioPlayerTableViewCell *cell = (MDAudioPlayerTableViewCell *)[tbl dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil)
    {
        cell = [[MDAudioPlayerTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

我如何为iOS7解决它？

假设你有一个扩展UIView的cellview

@interface CellView : UIView

- (void) drawRect:(CGRect)r;

@end

在您的实现中,您有类似这样的东西

@implementation CellView

- (void)drawRect:(CGRect)r {
    [(Cell *)superview drawContentView:r];
}

@end 

只需替换它

@implementation CellView

- (void)drawRect:(CGRect)r {
    UIView *superview = [self superview];
    if (![superview isKindOfClass:[UITableViewCell class]]) {
        superview = [superview superview];
    }
    [(Cell *)superview drawContentView:r];
}

@end
