我试图用我自己的数据集运行LibSVMAndroidClassification Android项目.它与已经提供的数据集完美配合,当我使用100行(小于原始大小的1%)的csv时,它也可以正常工作.但是当我尝试使用例如1000行的"Train CSV"时,我看到了这个错误.我甚至试图在Manifest.xml中设置android:largeHeap ="true"但没有任何改进.

这是我的logcat转储.

我想创建一个UIButton来显示在UIImageView上.我的代码段如下所示:

imageView = [[UIImageView alloc] initWithImage:image]; //initWithImage:image

imageView.userInteractionEnabled = YES; //to enable touch interaction with image



UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setTitle:@"ClickMe" forState:UIControlStateNormal];
[btn.titleLabel setFont:[UIFont systemFontOfSize:16]];


 btn.frame = CGRectMake(340, 550, 70, 50);

[btn addTarget:self action:@selector(onClickHotSpotButton)   forControlEvents:UIControlEventTouchUpInside]; //it wasnt working


[imageView addSubview:btn];
[self addSubview:imageView]; 

我的应用程序在我想要的图像的一部分上显示按钮,但它不响应点击图像.相反,它确实检测到单击,因为它在检测时记录输出.但我希望这个按钮被点击选择并执行一些功能.

提前致谢.
