创建数组规定每组个数

NSArray *array = [UIFont familyNames];

_fontArray  = [[NSMutableArray alloc]initWithCapacity:13];

NSMutableArray *temp = nil;

for (int index = 0; index < [array count]; index++) {

//取出字体

NSString *font =array[index];

if (index % 5 == 0) {

temp =[[NSMutableArray alloc]initWithCapacity:5];

[_fontArray addObject:temp];

[temp release];

}//将整除5时，创建temp数组，添加到 _fontArray

[temp addObject:font];//将字体放到temp 中

}

//将字体放入数组
