缺乏bundle display name的提示json
不在项目中修改文件数组
致使missing file服务器
使用命令行删除全部的.svn文件网络
sudo find /Users/apple/Documents/已完成项目/PJZJ/pjw178/ -name ".svn" -exec rm -r {} \;app
能够参考我写的另外一篇博客中第一条进行定位处理svn

以下代码会产生一个数组越界的错误测试
NSArray *array=@[@"1",@"2"]; NSString *string=array[2];
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 1]'
NSMutableArray *array=[NSMutableArray array]; NSString *string; [array addObject:string]; //以上代码会报错,由于string为nil *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'
NSString *string; NSDictionary *dict=@{@"key1":string}; *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]'
不支持text解析spa
json解析错误.net
非法开始数字 02, 很是蛋疼
404错误
检查网址吧,尝试http测试工具。多是网址错误或者服务器挂了
-(UIImage *)imageAtTime:(float)time asset:(AVURLAsset *)avAsset{ CMTimeScale timeScale=avAsset.duration.timescale; AVAssetImageGenerator *gen = [[AVAssetImageGenerator alloc] initWithAsset:avAsset]; gen.appliesPreferredTrackTransform = YES; CMTime imageTime ; float vedioTime=CMTimeGetSeconds(avAsset.duration); if (time>CMTimeGetSeconds(avAsset.duration)) { imageTime=CMTimeMakeWithSeconds(avAsset.duration.value,timeScale); }else{ imageTime = CMTimeMakeWithSeconds(time, timeScale); } NSError *error = nil; CMTime actualTime; CGImageRef image = [gen copyCGImageAtTime:imageTime actualTime:NULL error:&error]; UIImage *thumb = [[UIImage alloc] initWithCGImage:image]; if (error) { NSLog(@"error%@",error); } return thumb; }
没有明显的报错信息,就是每次执行完这个语句,内存就会不断增长。
在处理图片完成后须要加入 CFRealease释放内存
CFRelease(image);
tableview cell 标示符重复
数据类型转换错误
