我有var lights_array = [];
$.when($.getJSON("resources/php/getjson.php",function(data){
})).then(function(json){
var verajson = json;
var lights_obj = verajson.devices;
for (i = 0; i < verajson.devices.length; i++) {
var lights_ids = verajson.devices[i].id;
lights_array.push(lights_ids);
}
console.log(lights_array[9]); //I get on console the value of the index 9 on the console
});
console.log(lights_array[9]); //I get an "underfined" here
型号：
Player.h：
PlayerPlayer.m：
#import <Foundation/Foundation.h>
@interface Player : NSObject
@property (nonatomic, strong) UIImage *image;
@property (nonatomic, strong) NSMutableArray *answers;
@end
然而，这会显示错误：#import <Foundation/Foundation.h>
#import "Player.h"
@interface Player ()
@end
@implementation Player
- (id)init {
if (self = [super init]) {
self.answers = [[NSMutableArray alloc] init];
self.image = [UIImage imageNamed:@"defaultProfileImage"]; // <-------------- error
}
return self;
}
@end
我如何在模型中使用UIImage？
答案 0 :(得分：5)
您需要导入
#import <UIKit/UIKit.h>
以便识别UIImage
