我正在做一个CABasicAnimation并从嵌套的NSMutableArray中获取值。
第一次运行时一切都很棒但是在使用自定义函数或viewDidLoad再次调用时崩溃。
我把它分隔到这一行
int int1 = [[[locationsArray objectAtIndex:0] objectAtIndex:0 ]integerValue] ;
我认为这与int不是指针有关，但我已经迷失了，因为必须获得值而不会第二次崩溃

@interface TalentRVC : UIViewController <locationGlobalMenuDelegate, industryGlobalMenuDelegate>{

@end
的.m
-(void)buildArrays {
locationsArray = [NSMutableArray arrayWithCapacity: 8];
for (int i = 0; i!=8; i++){
NSMutableArray *array = [NSMutableArray arrayWithCapacity: 8];
[locationsArray addObject: array];
}
//Africa
[[locationsArray objectAtIndex:0] addObject: [NSNumber numberWithInt: 83]];
...
//Middle East
[[locationsArray objectAtIndex:1] addObject: [NSNumber numberWithInt: 89]];
...
NSLog(@"Built locationsArray");
}
所以在第一次运行locationsArray后从内存中转储？如果是这样，我该怎么办？
答案 0 :(得分：0)
更改此
locationsArray = [NSMutableArray arrayWithCapacity: 8];
到这个
locationsArray = [[NSMutableArray alloc] initWithCapacity: 8];
如果您使用ARC，您就完成了。如果不是，你必须考虑再次释放这个记忆的位置。
