我有一个@property (nonatomic,retain) NSMutableArray *transfer_array;
.h 文件,我有一个 .m 文件
@synthesize transfer_array = _transfer_array;
- (id)init
{
self = [super init];
if(self) {
self.transfer_array = [[NSMutableArray alloc] init];
}
return self;
}
我在这个函数中将对象添加到数组中
- (id)display:(double)imageXX andY:(double)imageYY withName:(NSString *)namee{
//if((self == [super init])){
NSLog(@"````````````````````````````````````````````````````````");
NSLog(@"imageX: %f",imageXX);
NSLog(@"imageY: %f", imageYY);
NSLog(@"name: %@", namee);
labelPoi = [[Poi alloc] init];
labelPoi.imageLocationX = imageXX;
labelPoi.imageLocationY = imageYY;
labelPoi.name = namee;
[self.transfer_array addObject:labelPoi];
每当我尝试访问另一个实例中的数组元素时,对象就会成功添加,例如:
- (void)viewDidLoad{
[super viewDidLoad];
NSLog(@"transfer_array count: %lu",(unsigned long)self.transfer_array.count);
然后数组为空。
任何帮助,将不胜感激!
