背景描述
#import "TMUStoreMemoryDataCache.h"
static TMUStoreMemoryDataCache * _instance = nil;
@implementation TMUStoreMemoryDataCache
+ (instancetype)shareInstance{
//static TMUStoreMemoryDataCache * instance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_instance = [[TMUStoreMemoryDataCache alloc]init];
});
return _instance;
}
我在一下代码中创建的单例，使用全局的static _instacce，就会出现以下错误，这个断点即使不打开All Exceptions`也会出现。后来我将上面全局的变量改成局部的，就不在出错。问题原因尚未找到
Execution was interrupted, reason: EXC_BREAKPOINT (code=1, subcode=0x101c2f740). The process has been returned to the state before expression evaluation.
解决
将全局_instace换成局部的instace，就能解决
原因
还未找到具体原因
