ios - Xcode 7 Null 传递给需要非空参数的被调用方

Question

我更新了 xcode 7 并给出了这个错误

Null 传递给需要非空参数的被调用者

 _recorder = [[AVAudioRecorder alloc]initWithURL:[NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/%@.%@", [NSHomeDirectory() stringByAppendingString:@"/Documents"], name, extension]] settings:nil error:nil];

Answer 1

如果困扰您的是警告，您可以使用此 -Wnonnull

抑制警告

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wnonnull"

_recorder = [[AVAudioRecorder alloc]initWithURL:[NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/%@.%@", [NSHomeDirectory() stringByAppendingString:@"/Documents"], name, extension]] settings:nil error:nil];

#pragma clang diagnostic pop
