存档时Xcode中存在几个键入问题的问题

在构建时我没有得到任何警告,但在归档时,我得到了很多涉及stringWithFormat的输入警告和一个使用NSNotFound的问题.我能够解决除了一个之外的所有stringWithFormat问题,并且仍然被NSNotFound问题困扰.这些列在下面.谢谢你的帮助

以下代码……

if ([[NSString stringWithFormat:@"%.*s",[data length],[data bytes]] isEqualToString:@"Success"]) {
        return YES;
    }

为格式字符串生成此警告…

Field precision should have type ‘int’,but argument has type ‘NSUInteger’ (aka ‘unsigned long’)

以下代码……

if (![_response rangeOfString:@"|TreatmentCards|0|"].location == NSNotFound) {
         return NO;

    }

生成…

Comparison of constant ‘NSNotFound’ (9223372036854775807) with expression of type ‘int’ is always false

NSUInteger location = [_response rangeOfString:@"|TreatmentCards|0|"].location;

if (location != NSNotFound) {
    return NO;
}
