我想在该项目中安装此示例SegmentedControl，然后转到老式wai（将HMSegmentedControl.h和HMSegmentedControl.m添加到我的项目中。）在MyViewController.n和MyViewController中创建ViewController（来自示例项目）的代码并将其放入.m，启动后出现了这样的错误-如何解决？

编辑：
该行以绿色突出显示，应用程序停止，线程1：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"]]];
最佳答案
您已将Map类设置为情节提要或xib中的任何对象。
删除Map类查看图片
编辑：现在您有以下错误，它告诉您您正在尝试将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]'
若要跟踪此错误，请添加异常断点并运行项目。 （如下图所示）
现在，您在以下行出现错误：
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"]]];
这意味着您的图片之一是
nil。检查包中的所有图像。关于ios - 不能与Storyboard一起使用HMSegmentedControl，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/29234656/
