Question

我想在我的项目中安装这个示例SegmentedControl，我去了老式的wai（将HMSegmentedControl.h和HMSegmentedControl.m添加到我的项目中。）创建并将ViewController的代码（来自示例项目）放在MyViewController中。 n和MyViewController.m，在发布后出现了这样的错误 - 如何解决？

编辑：以绿色突出显示此行，应用程序停止，第1行：断点1.1

HMSegmentedControl *segmentedControl2 = [[HMSegmentedControl alloc] initWithSectionImages:@[[UIImage imageNamed:@"1"], [UIImage imageNamed:@"2"], [UIImage imageNamed:@"3"], [UIImage imageNamed:@"4"]] sectionSelectedImages:@[[UIImage imageNamed:@"1-selected"], [UIImage imageNamed:@"2-selected"], [UIImage imageNamed:@"3-selected"], [UIImage imageNamed:@"4-selected"]]];

Answer 1

您已将Map类设置为storyboard或xib中的任何对象。

删除Map课程，请参阅图片

编辑：现在您有一个跟随错误，它告诉您正在尝试将nil对象插入数组或字典。

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderArray initWithObjects:count:]: attempt to insert nil object from objects[0]'

要跟踪此错误，请添加异常断点并运行该项目。（如下图所示）

enter image description here

现在您在以下行中遇到错误：

 HMSegmentedControl *segmentedControl2 = [[HMSegmentedControl alloc] initWithSectionImages:@[[UIImage imageNamed:@"1"], [UIImage imageNamed:@"2"], [UIImage imageNamed:@"3"], [UIImage imageNamed:@"4"]] sectionSelectedImages:@[[UIImage imageNamed:@"1-selected"], [UIImage imageNamed:@"2-selected"], [UIImage imageNamed:@"3-selected"], [UIImage imageNamed:@"4-selected"]]];

这意味着您的一张图片为nil。检查捆绑中的所有图像。

Answer 2

您似乎有一个未知的班级Map in your interface builder。它是此View Controller的UIView：

。

您应该删除Map（如N J Gadhiya所示）或创建一个继承自Map的课程UIView，具体取决于您要执行的操作。

您是否在故事板/ xib中添加了UIMapView？如果是这样，您需要向继承自Map的项目UIMapView添加一个类。

如果您已将另一个项目定义为具有类Map，那么您必须创建一个继承自该元素来自的类型的类Map。

不使用故事板来处理HMSegmentedControl
