在Xcode中，我遇到了一些应该正常生成的奇数错误。
首先，在
- (void)touchesMoved:(NSSet *)touches withEvent(UIEvent *)event {
[self touchesBegan:touches withEvent:event];
marblebeingdragged = NO;
}
它给了我错误:
error: Semantic Issue: Use of undeclared identifier 'touchesMoved'
in the first line: `expected ';' before ':' token`
另外，在我的switch语句中:(请注意case和break语句中注释的错误)
switch (marblecolor) {
case 1: //Aqua
plusone.image = [UIImage imageNamed: @"Aqua/+1"]; //Parse Issue: Extraneous ']' before ';'
plustwo.image = [UIImage imageNamed: @"Aqua/+2"];
plusthree.image = [UIImage imageNamed: @"Aqua/+3"];
minusone.image = [UIImage imageNamed: @"Aqua/-1"];
minustwo.image = [UIImage imageNamed: @"Aqua/-2"];
minusthree.image = [UIImage imageNamed: @"Aqua/-3"];
break; //Semantic Issue: 'break' statement not in loop or switch statement
case 2: //Blue //Semantic Issue: 'case' statement not in switch statement
plusone.image = [UIImage imageNamed: @"Blue/+1"];
plustwo.image = [UIImage imageNamed: @"Blue/+2"];
plusthree.image = [UIImage imageNamed: @"Blue/+3"];
minusone.image = [UIImage imageNamed: @"Blue/-1"];
minustwo.image = [UIImage imageNamed: @"Blue/-2"];
minusthree.image = [UIImage imageNamed: @"Blue/-3"];
break; //Semantic Issue: 'break' statement not in loop or switch statement
case 3: //Green //Semantic Issue: 'case' statement not in switch statement
plusone.image = [UIImage imageNamed: @"Green/+1"];
plustwo.image = [UIImage imageNamed: @"Green/+2"];
plusthree.image = [UIImage imageNamed: @"Green/+3"];
minusone.image = [UIImage imageNamed: @"Green/-1"];
minustwo.image = [UIImage imageNamed: @"Green/-2"];
minusthree.image = [UIImage imageNamed: @"Green/-3"];
break; //Semantic Issue: 'break' statement not in loop or switch statement
case 4: //Semantic Issue: 'case' statement not in switch statement
plusone.image = [UIImage imageNamed: @"Grey/+1"];
plustwo.image = [UIImage imageNamed: @"Grey/+2"];
plusthree.image = [UIImage imageNamed: @"Grey/+3"];
minusone.image = [UIImage imageNamed: @"Grey/-1"];
minustwo.image = [UIImage imageNamed: @"Grey/-2"];
minusthree.image = [UIImage imageNamed: @"Grey/-3"];
break; //Semantic Issue: 'break' statement not in loop or switch statement
case 5: //Pink //Semantic Issue: 'case' statement not in switch statement
plusone.image = [UIImage imageNamed: @"Pink/+1"];
plustwo.image = [UIImage imageNamed: @"Pink/+2"];
plusthree.image = [UIImage imageNamed: @"Pink/+3"];
minusone.image = [UIImage imageNamed: @"Pink/-1"];
minustwo.image = [UIImage imageNamed: @"Pink/-2"];
minusthree.image = [UIImage imageNamed: @"Pink/-3"];
break;
}
最后，在我的
@end中给出了错误:expected declaration or statement at end of input。有关错误的任何线索？
最佳答案
对于初学者，您的- (void)touchesMoved:(NSSet *)touches withEvent(UIEvent *)event {行在withEvent之后需要一个冒号，因此它应该是- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {。
解决此问题，我们将看看有什么用。 (编辑:查看您的其他错误，在您修复方法声明拼写错误后，它们可能会消失。我当然希望@end错误会消失。)
