适合iOS开发,入门练手精品小项目--(1)Tom猫源码下载

admin

  一直以来想着,整理一下学习iOS开发的经历.借着这段空闲的时间,特意为想入门iOS开发,或者刚入门的新手,提供一些练手的小项目.
    Tom猫游戏,想必大家都很熟悉,各种版本的Tom猫.别看着这样一个小小的游戏,想要把它做成比较完美的项目,必须要多思考.比如说:1.界面的合理搭建;2.代码的封装性;3.CPU利用率;4.内存的优化.
    根据以上的几个侧重点,重写了Tom猫这个小项目,希望能对新手们有所帮助.大神们么井喷,本人实属入门级别而已.

(1)延时加载技术,也叫懒加载.提高CPU的利用率,加快启动速度.

1. - (NSDictionary *)imgs{
   
2. 
   
3. if (!_imgs) {
   
4. 
   
5. NSString *path = [[NSBundle mainBundle] pathForResource:@"tom.plist" ofType:nil];
   
6. 
   
7. NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];
   
8. 
   
9. _imgs = dict;
   
10. 
    
11. }
    
12. 
    
13. return _imgs;
    
14. 
    
15. }
    

复制代码

(2)代码的封装:注意设置控件的tag值时,最后使用100以后的值,避免与Xcode内部系统产生冲突.

1. - (IBAction)clickBtn:(UIButton *)sender {
   
2. 
   
3. //    NSLog(@"sender.tag = %ld",(long)sender.tag);
   
4. 
   
5. //根据绑定的tag值,来进行判断
   
6. 
   
7. switch (sender.tag) {
   
8. 
   
9. case 101:
   
10. 
    
11. {
    
12. 
    
13. int count = [self.imgs[@"pie"] intValue];
    
14. 
    
15. [self playAnimationWithCount:count andPrefixName:@"pie"];
    
16. 
    
17. }
    
18. 
    
19. break;
    
20. 
    
21. case 102:
    
22. 
    
23. {
    
24. 
    
25. int count = [self.imgs[@"cymbal"] intValue];
    
26. 
    
27. [self playAnimationWithCount:count andPrefixName:@"cymbal"];
    
28. 
    
29. }
    
30. 
    
31. break;
    
32. 
    
33. case 103:
    
34. 
    
35. {
    
36. 
    
37. int count = [self.imgs[@"drink"] intValue];
    
38. 
    
39. [self playAnimationWithCount:count andPrefixName:@"drink"];
    
40. 
    
41. }
    
42. 
    
43. break;
    
44. 
    
45. case 104:
    
46. 
    
47. {
    
48. 
    
49. int count = [self.imgs[@"eat"] intValue];
    
50. 
    
51. [self playAnimationWithCount:count andPrefixName:@"eat"];
    
52. 
    
53. }
    
54. 
    
55. break;
    
56. 
    
57. case 105:
    
58. 
    
59. {
    
60. 
    
61. int count = [self.imgs[@"fart"] intValue];
    
62. 
    
63. [self playAnimationWithCount:count andPrefixName:@"fart"];
    
64. 
    
65. }
    
66. 
    
67. break;
    
68. 
    
69. case 106:
    
70. 
    
71. {
    
72. 
    
73. int count = [self.imgs[@"scratch"] intValue];
    
74. 
    
75. [self playAnimationWithCount:count andPrefixName:@"scratch"];
    
76. 
    
77. }
    
78. 
    
79. break;
    
80. 
    
81. case 107:
    
82. 
    
83. {
    
84. 
    
85. int count = [self.imgs[@"knockout"] intValue];
    
86. 
    
87. [self playAnimationWithCount:count andPrefixName:@"knockout"];
    
88. 
    
89. }
    
90. 
    
91. break;
    
92. 
    
93. case 108:
    
94. 
    
95. {
    
96. 
    
97. int count = [self.imgs[@"angry"] intValue];
    
98. 
    
99. [self playAnimationWithCount:count andPrefixName:@"angry"];
    
100. 
     
101. }
     
102. 
     
103. break;
     
104. 
     
105. case 109:
     
106. 
     
107. {
     
108. 
     
109. int count = [self.imgs[@"stomach"] intValue];
     
110. 
     
111. [self playAnimationWithCount:count andPrefixName:@"stomach"];
     
112. 
     
113. }
     
114. 
     
115. break;
     
116. 
     
117. case 110:
     
118. 
     
119. {
     
120. 
     
121. int count = [self.imgs[@"foot_right"] intValue];
     
122. 
     
123. [self playAnimationWithCount:count andPrefixName:@"footRight"];
     
124. 
     
125. }
     
126. 
     
127. break;
     
128. 
     
129. case 111:
     
130. 
     
131. {
     
132. 
     
133. int count = [self.imgs[@"foot_left"] intValue];
     
134. 
     
135. [self playAnimationWithCount:count andPrefixName:@"footLeft"];
     
136. 
     
137. }
     
138. 
     
139. break;
     
140. 
     
141. default:
     
142. 
     
143. break;
     
144. 
     
145. }
     
146. 
     
147. }

(3)设置序列帧动画效果:注意图片无缓存加载方式,以及图片对象数组的及时释放.

1. - (void)playAnimationWithCount:(int)count andPrefixName:(NSString *)name{
   
2. 
   
3. if(self.imgView.isAnimating){
   
4. 
   
5. return;
   
6. 
   
7. }
   
8. 
   
9. NSMutableArray *imgArray = [NSMutableArray array];
   
10. 
    
11. for (int i = 0; i < count; i++) {
    
12. 
    
13. NSString *imgName = [NSString stringWithFormat:@"%@_%02d.jpg",name,i];
    
14. 
    
15. NSString *imgPath = [[NSBundle mainBundle] pathForResource:imgName ofType:nil];
    
16. 
    
17. UIImage *image = [UIImage imageWithContentsOfFile:imgPath];
    
18. 
    
19. UIImage *newImage = [self getImage:image andSize:[UIScreen mainScreen].bounds.size];
    
20. 
    
21. [imgArray addObject:newImage];
    
22. 
    
23. }
    
24. 
    
25. self.imgView.animationImages = imgArray;
    
26. 
    
27. self.imgView.animationDuration = count * 0.1;
    
28. 
    
29. self.imgView.animationRepeatCount = 1;
    
30. 
    
31. [self.imgView startAnimating];
    
32. 
    
33. //必须把创建的数组,在播放动画完成后,置为nil,进行释放.
    
34. 
    
35. [self.imgView performSelector:@selector(setAnimationImages:) withObject:nil afterDelay:count * 0.1];
    
36. 
    
37. }
    

复制代码

(4)开辟子线程对图片进行重采集工作,减轻主线程的任务,加快速度,以及优化内存.

1. - (UIImage *)getImage:(UIImage *)image andSize:(CGSize)size{
   
2. 
   
3. UIGraphicsBeginImageContext(size);
   
4. 
   
5. CGRect imageRect = CGRectMake(0, 0, size.width, size.height);
   
6. 
   
7. [image drawInRect:imageRect];
   
8. 
   
9. UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
   
10. 
    
11. UIGraphicsEndImageContext();
    
12. 
    
13. return newImage;
    
14. 
    
15. }
    

复制代码

预览Tom猫项目的效果:





总结:每写一个新的项目,或者老项目,其实知识点都是在逐渐累加的过程.新的方法,新的技术,新的优化效果等等,都是在实践操作,查资料,看博客等中获取到的.编程之路,就是一条学习之路.
